    The OCE Database 12c certifications include Maximum Availability, Data Guard Administrator, RAC and Grid Infrastructure Administrator, and Performance Management and Tuning credentials. consummate these certifications require prerequisite certifications. Performance Management and Tuning takes the OSP Database 12c as a prerequisite, while Data Guard Administrator candidates absorb the election of earning either the OCP Database 12c or 11g credential. The RAC and Grid Infrastructure Administrator provides candidates the most flexibility, allowing candidates to choose from the OCP Database 11g, OCP Databases 12c, Oracle Certified Expert – true Application Clusters 11g and Grid Infrastructure Administration, or OCE Database 10g true Applications Clusters Administration.

    Once the prerequisite credentials are met, candidates can then achieve Data Guard Administrator, RAC and Grid Infrastructure Administrator or Performance Management and Tuning by passing one exam. Achieving OCP 12c plus the RAC and Grid Infrastructure Administration and Data Guard Administration certifications earns the Maximum Availability credential.

    Oracle Database Certified Implementation Specialist

    Oracle besides offers three Certified Implementation Specialist credentials: the Oracle true Application Clusters 12c, Oracle Database Performance and Tuning 2015, and Oracle Database 12c. Specialist credentials target individuals with a background in selling and implementing Oracle solutions. Each of these credentials require candidates to pass a sole exam to earn the designation.  

    Oracle Industries Certifications

    Oracle Industries is another sizeable category, with more than 25 individual certifications focused on Oracle software for the construction and engineering, communications, health sciences, insurance, tax and utilities industries. consummate these certifications are Certified Implementation Specialists for the various Oracle industry products, which means they identify individuals who are proficient in implementing and selling industry-specific Oracle software.

    Oracle Java and Middleware Certifications

    The Java and Middleware certifications are spread across several subcategories, such as industry Intelligence, Application Server, Cloud Application, Data Integration, Identity Management, Mobile, Java, Oracle Fusion Middleware evolution Tools and more. Java and Middleware credentials picture consummate levels of the Oracle Certification Program — Associate, Professional and so on — and include Java Developer, Java Programmer, System Administrator, Architect and Implementation Specialist.

    The highly approved Java category has certifications for Java SE (Standard Edition), and Java EE (Enterprise Edition) and Web Services. Several Java certifications that require a prior certification accept either the corresponding Sun or Oracle credential.

    Oracle Operating Systems Certifications

    The Oracle Operating Systems certifications include Linux and Solaris. These certifications are geared toward administrators and implementation specialists.

    The Linux 6 certifications include OCA and OCP Linux 6 System Administrator certifications, as well as an Oracle Linux Certified Implementation Specialist certification. The Linux 6 Specialist is geared to partners but is open to consummate candidates. Both the Linux OCA and Specialist credentials require a sole exam. To achieve the OCP, candidates must first earn either the OCA Linux 5 or 6 System Administrator or OCA Linux Administrator (now retired) credential, plus pass an exam.

    The Solaris 11 certifications include the OCA and OCP System Administrator certifications as well as an Oracle Solaris 11 Installation and Configuration Certified Implementation Specialist certification. The OCA and OCP Solaris 11 System Administrator certifications identify Oracle Solaris 11 administrators who absorb fundamental knowledge of and base-level skills with the UNIX operating system, commands, and utilities. As indicated by its name, the Implementation Specialist cert identifies intermediate-level implementation team members who install and configure Oracle Solaris 11.

    Oracle Systems Certifications­

    Oracle's Systems certifications include Engineered Systems (Big Data Appliance, Ex­­adata, Exalogic Elastic Cloud, Exalytics, and Private Cloud Appliance), Servers (Fujitsu and SPARC) and Storage (Oracle ZFS, Pillar Axiom, Tape Storage, glitter Storage System). Most of these certifications are geared toward individuals who sell and implement one of the specific solutions. The Exadata certification subcategory besides includes Oracle Exadata X3, X4 and X5 Expert Administrator certifications for individuals who administer, configure, patch and monitor the Oracle Exadata Database Machine platform.

    Oracle Virtualization Certifications

    The Virtualization certifications cover Oracle Virtual Machine (VM) Server for X86. Oracle offers two Certified Implementation Specialists credentials, one targeting Oracle VM 3.0 for X86 and the other focused on VM 2.0 for X86. Both specialist credentials recognize individuals who sell and implement Oracle VM solutions.  

    The Oracle VM 3.0 for x86 Certified Implementation Specialist Certification is geared toward the intermediate-level team member who is proficient in installing OVM 3.0 Server and OVM 3.0 Manager components, discovering OVM Servers, configuring network and storage repositories and more. Candidates interested in the VM 2.0 credential should note that the exam retires on May 31, 2018.

    Related Jobs and Careers

    The sheer breadth and depth of Oracle's certification program is rife with chance for professionals who want to work with Oracle technologies, or who already carry out and want their skills to live recognized and validated. Although there are many specific Oracle products to specialize on in varying capacities, the main job roles are administrators, architects, programmers/developers and implementation specialists.

    Every company that runs Oracle Database, Oracle Cloud, Oracle Linux or Solaris, Oracle operating systems and so on needs qualified administrators to deploy, maintain, monitor and troubleshoot these solutions. They besides requisite architects to artery and design solutions that meet industry needs and are preempt to the specific environments in which they’re deployed.

    On the evolution front, ComputerWorld indicates that programmers and developers continue to live "leading players in the IT world." That magazine ranks associated skills as the most sought-after by hiring managers in 2017, tied with aid desk support. (Database administration isn't far behind.) A quick search on Indeed.com results in over 12,000 hits for "Oracle developer," which is a considerable indication of both requisite and desire. Not only carry out developers create and modify Oracle software, they often must know how to design software from the bottom up, package products, import data, write scripts and develop reports.

    And of course, Oracle and its partners will always requisite implementation specialists to sell and deploy the company's solutions. This role is typically accountable for tasks that must live accomplished to catch a solution up and running in a client's environment, from creating a project artery and schedule, to configuring and customizing a system to match client specifications.

    Oracle Training and Resources

    It's not surprising that Oracle has an extensive library of exam preparation materials. Check the Oracle University website (education.oracle.com) for hands-on instructor-led training, virtual courses, training on demand, exam preparation seminars, practice exams and other training resources.

    A candidate's best bet, however, is to first choose a certification path and then follow the links on the Oracle website to the required exam(s). If training is recommended or additional resources are available for a particular exam, Oracle lists them on the exam page.

    Another considerable resource is the Oracle Learning Paths web page, which provides a lengthy list of Oracle product-related job roles and their recommended courses.


    Where is Java EE headed to? [UPDATE] | killexams.com true questions and Pass4sure dumps

    Discussions about Java EE‘s future persist. After JAXenter launched its interview chain with Java EE Guardians, people started a conversation on Reddit, so they decided to meander it here and invite everyone to participate. 

    Java Champion Lukas Eder

    We asked Java Champion Lukas Eder to comment on the current state of Java EE, as well as on the mount of Java EE Guardians and MicroProfile.

    JAXenter: Considering the current state of Java EE, carry out you referee they requisite an initiative to protect its legacy?

    Lukas Eder: That’s a very bewitching open-ended question. And they can gape at it from different angles (all subjective, of course). First off:

    Do they requisite Java EE in the first place?

    The Java EE “market” is big; a lot of companies (let’s convoke them companies) want to build “standard” software and a lot of infrastructure software vendors (let’s convoke them vendors) want to catch a piece of the cake by selling “standard” software platforms (and/or services related to the “standard” platforms) to these companies.

    These companies want to absorb as slight cognitive friction as workable when going from one project to the next, but it is a poisonous thing to absorb too many choices in terms of technology. They pay the vendors to guarantee this requisite of friction. Many companies catch a free ride because many vendors present the platform software for free as Open Source.

    There is no Java EE standard.

    Java EE evangelists used to fancy to paint a standards-biased picture where the UI framework market (often their favorite example) was shared mostly between Java EE’s JSF and Spring’s MVC. Of course, as the epigram goes: “The only statistics you can confidence are those you falsified yourself”. If you gape at “the market” from a different angle, there’s besides Angular JS which dominates it, probably much more than JSF and MVC combined.

    We’ve had Struts, before that JSP (still the best Java web UI tech if you search information from me) and before Java EE (and before J2EE), there were other technologies, and surely, in the future, there will live other technologies. And that’s just talking about UI frameworks. So, you can behold that even within the “standards” scope there are a lot of choices — which is not surprising, given XKCD 927.

    So, in my opinion, there is no Java EE standard. Java EE is only a recommended set of libraries that are guaranteed by Java EE certification to work together.

    Therefore, the confess to the question carry out we need Java EE in the first space is “Yes.” However, this is the case only if said certification is your highest priority as an API consumer. Spring is an alternative to the Java EE “standards” where innovation and unusual features are added without too much of a formal process by a sole vendor: Pivotal. They noiseless add exactly the very value as Java EE to most customers, though. That value is: “It just works”. The contrast is the following: there’s no certification, but confidence in the vendor after many years of excellent delivery. And, there’s no competition in the implementation process because many APIs are proprietary Open Source.

    Spring is an alternative to the Java EE “standards”.

    Of course, if you build decent integration tests yourself, there’s a third alternative to Java EE and Spring. You don’t requisite either. You can choose any whimsical set of third party libraries as long as you confidence each individual vendor to “do the privilege thing” (which is often the case anyway, no matter if you’re using Java EE or Spring). For instance, if you’re using jOOQ (or Hibernate), you can expend that library in a “standalone application”, in a Spring application, or in a Java EE application just the same.

    Now back to the actual question:

    Do they requisite a group fancy the Java EE Guardians?

    If Java EE was a truly open gauge (like HTML, or SQL to some extent), they wouldn’t live in the situation that we’re in. Oracle would just live one more stakeholder in a large consortium and it would live their own election whether they withdraw from the consortium or not, without affecting the consortium as a whole.

    Still, because of the artery the JCP is organized, Oracle pretty much dictates what happens in the “standard”. For instance, the TCK for most aspects of Java EE are not open, freely available or even available without the requisite to accept very restrictive terms.

    Should Oracle “secretly” want Java EE’s death, then that’s exactly what’s going to happen.

    Now, Oracle seems to absorb lost interest in Java EE (although they carry out not know that for sure) and frankly they didn’t carry out an excellent PR job explaining their strategy. There is a lot of skepticism in the industry with respect to the future of Java EE. Given Oracle’s tight grip on the legal aspects of Java EE, there can live no fork or truly open gauge without Oracle’s consent. So, should Oracle “secretly” want Java EE’s death, then that’s exactly what’s going to happen.

    I personally don’t referee the Java EE Guardians can carry out a lot in this case. It’s worth trying, sure. The Guardians consummate absorb a mountainous personal stake given the fact that their professional careers depend on Java EE. But as I explained above, there are non-certified alternatives fancy Spring, or random third party library collections that carry out the job just the same, so, perhaps, the best artery to retract forward is to create a unusual “Spring” from scratch that is governed by a true open gauge consortium, free from any legal ties to Java EE, and with or without Oracle. Let’s convoke it … “Summer” (Note that the community just published “MicroProfile”, which seems to live an initiative which does precisely that.)

    JAXenter: How could Java EE live brought forward? Should Oracle live convinced that they will catch a better recrudesce from continuing to invest in Java EE? Should the focus remain on the community’s support? 

    Lukas Eder: There was an bewitching discussion on Reddit’s /r/java just recently. /user/thesystemx, who frequently comments on the subject, said:

    At terminal Devoxx I spoke to several spec leads and people from Oracle, and they told me (off the record) that the direct licensing income lonely is enough to quicken Java EE, and that excludes the tag on sales for related products.

    And my first thought was…

    The direct licensing income of a sole Exadata installation is probably enough to quicken Java EE as well, so perhaps this is an order of magnitude thing (i.e. a “what’s this boring, irrelevant stuff over there desist wasting my time thing”)

    As you can see, as a community, they can only speculate about what’s going on privilege now. I believe that the industry is not bewitching enough for Oracle. Plus, neither is the community because it isn’t Oracle’s. It’s Red Hat’s, Pivotal’s, IBM’s, and everyone else’s community. Oracle inherited a rather difficult legacy from Sun. Jonathan Schwartz (the former Sun CEO) testified in court in the Oracle vs. Google case that Java was “free”. Quoting from the Ars Technica series:

    The strategy was, they conform on these open APIs, then they compete on implementations.

    This is what an open gauge does, and it was certainly Sun’s intention to “sell” Java EE as an (almost) open standard. But perhaps, after consummate these years. After doing some proper math, it just showed that this particular (almost) open gauge provides benefits to competitors much more than to Oracle. Again, as we’re lacking official PR from Oracle, they can only guess. The fact is, they as a community cannot bring forward Java EE without Oracle. Oracle CEO Safra Catz made this very limpid in the Oracle vs. Google lawsuit:

    […] And that Android was an unauthorized fork of Java.

    This means that any unauthorized fork of Java EE will have the very portion as Android. Besides, I sincerely doubt that they can convince Oracle to give us more free lunch, so the future of Java EE is, without an actual statement from Oracle’s side, on hold.

    Mike Croft —Java Middleware consultant at Payara

    We asked Payara’s Mike Croft to comment on the current state of Java EE, as well as on the mount of Java EE Guardians and MicroProfile.

    JAXenter: Considering the current state of Java EE, carry out you referee they requisite an initiative to protect its legacy? 

    Mike Croft: work on Java EE has slowed, but it hasn’t stopped. The JCP involves more than just Oracle, though they are the biggest players at the moment. The Java EE Guardians’ focus is on getting some action from Oracle; their belief is that this is crucial to the success of Java EE. I conform that movement from Oracle is valuable for the future of Java EE, whether that is Oracle working on the JSRs they lead or in relinquishing them to the community. It is valuable to bethink that Java EE isn’t only Oracle, however, and there are a huge number of people and corporations of varying size which absorb a vested interest in its future. The Guardians group is just one pains of many and consummate efforts are needed in this, just as in any community-led project.

    Java EE isn’t only Oracle, however, and there are a huge number of people and corporations of varying size which absorb a vested interest in its future.

    JAXenter: How could Java EE live brought forward? 

    Mike Croft: Java EE already has a artery to meander forward in the version 8 specifications. My personal view is that Oracle can noiseless stand to grow their industry by investing in Java EE. They absorb not heard any official, public response from Oracle as to their plans, so they can’t live positive that the requisite of activity is permanent or only temporary as they upshot more resource into the “other projects” that has been renowned on mailing lists. We, as a community, can’t stand noiseless and wait for confirmation, though.

    It’s this requisite of knowledge which has driven Red Hat, Payara, Tomitribe, IBM and the LJC, who each absorb significant interests in Java EE, to advertise microprofile.io as a artery to bring about open collaboration. This is not an pains designed to exclude Oracle, but to leverage the incredible power of the wider Java community to address the needs of modern Java EE users. The level is to iterate quickly and to collaborate openly on a standard. Standards are incredibly valuable in technology to avoid fragmentation and, from here, the future looks bright.

    Java Champion Lukas Eder

    JAXenter: Mike Croft said that the JCP involves more than just Oracle. What’s your prefer on that? 

    Lukas Eder: That’s exactly how it ought to be, but for historic reasons it’s not true, and probably never will be. The JCP *is* Oracle, mostly, from a legal and operative perspective.

    But Payara and the others who joined forces to create this MicroProfile initiative can create their own committee (as I’ve mentioned in my previous responses on JAXenter), which is truly open, governed by a foundation, not a corporation. There will noiseless live politics, of course, but it would certainly aid meander this forward as the legal hurdles would probably live much reduced.

    [MicroProfile’s strategy is to] catch up with Spring whose Spring Boot totally dominates the microservices hype.

    JAXenter: carry out you referee MicroProfile is hoping for a reaction from Oracle?

    Lukas Eder: I referee that MicroProfile backers carry out not want to add more FUD to the debate. They thus openly invite Oracle to join. In my opinion, however, the strategy is to meander forward with innovation and not wait for Oracle, but most importantly: to catch up with Spring whose Spring Boot totally dominates the microservices hype. If Oracle does determine to become Part of MicroProfile, fine. But in my opinion, that would live rather surprising.

    JAXenter: He besides mentioned that “standards are incredibly valuable in technology to avoid fragmentation”; you said there is no Java EE standard. Why are your viewpoints so different?

    Lukas Eder: Of course he says that. He couldn’t quicken Payara and not absorb this belief :).

    And I don’t fully disagree with Mike. What I signify by Java EE is not a “standard” is this: There are good, “obvious” standards and less good, less “obvious” ones.

    A satisfactory standard is a gauge that removes fragmentation where fragmentation creates friction, overhead, bureaucracy in the market without adding any value. satisfactory examples for satisfactory standards are:

  • Electric voltages
  • Electric outlets (I noiseless hope there will eventually live a world-wide standard, instead of dozens, but at least the EU mostly uses just one)
  • USB
  • Train track widths
  • DIN A4, A5 paper formats
  • JDBC
  • JMS
  • All of these standards simplify industry for everyone by destroying the industry of those who try to sell deviating, proprietary interfaces. For example, DIN A4 means 297mm x 210mm. Vendors of printers, photocopying machines, document processing software, paper, envelopes, binders, briefcases, etc. etc. can consummate uphold “the standard” and consumers don’t absorb to purchase a briefcase for JAXenter publications and a different briefcase for other documents.

    A sinful gauge is a “standard” that hinders innovation by adding complexity in a very opinionated environment.

    JDBC is an exceptionally satisfactory gauge in software, as it removes the requisite for knowing about vendor-specific APIs and network protocols in order to access mostly RDBMS (although it works besides with other data stores).

    There are some satisfactory Java EE standards, fancy JMS, Servlets, JavaMail and others, mostly those that define (again) protocol abstractions, or things that are too irksome to live implemented a second time in a different artery (JAXB, JavaMail).

    A sinful standard is a “standard” that hinders innovation by adding complexity in a very opinionated environment, where differing opinions are satisfactory for the market, as each belief can vary greatly in how it adds value to a consumer. There are a lot of industry standards fancy the ISO 9001 for quality management or the ISO 29119 software testing standards, which are mostly certifications that companies fancy to present off to impress customers. They don’t really signify anything concrete as it is much too intricate to derive from a simple yes/no flag what this really means in the context of a concrete corporation.

    Java EE “shines” here with sinful “standards” fancy EJB, MVC, JPA, JSF, CDI, Bean Validation, Batch, and much more. consummate of these things carry out not belong in a gauge because they are:

  • Complex
  • Often a sinful default choice
  • Often not the only choice, specifically not the de-facto election (e.g. bean validation, batch)
  • Very opinionated in terms of architecture and design, which greatly restricts the solution space for consumers
  • Take JSF, for instance. It’s a server-side UI component API specification. How many component APIs did they already have? AWT, Swing, JavaFX, Gwt, Vaadin, Wicket, JSF, and many others, lesser known ones. In this case, JSF is “just another” component API (specification). Of course, it’s one of the most approved ones today, but that’s only the case because it profits from the Java EE “brand”.

    JPA is a different story. It solves dozens of problems, which is a very sinful thing for a “standard” API. It solves:

  • Mapping (that’s the best part)
  • Querying (in several different, conflicting ways: mapping, utility finder methods, JPQL, criteria API, fetch graphs, aboriginal queries, query annotations, etc. etc., nonexistent of them are satisfactory, given that SQL is incredibly more powerful)
  • Native SQL (in my opinion, the stored procedure uphold shows the desperation in this API to withhold up with true world needs by shoe horning a feature into an API that was not designed for the mere actuality of stored procedures)
  • Transactions (Why? There’s already JTA…)
  • Locking
  • Caching
  • It’s a heterogeneous monster that should live split in 10 different APIs. Don’t catch me wrong. It’s fine for an *implementation* fancy Hibernate to present consummate these features out of the box. But the specification shouldn’t carry out that. It’s simply not a satisfactory standard.

    To confess your question: As I mentioned already in my previous answers, the industry likes having guarantees that positive things work together. It’s satisfactory to know that JDBC works and that jOOQ or Hibernate work on top of JDBC and that nonexistent of these APIs will wreck in the future. JDBC is a standard. jOOQ and Hibernate aren’t. They’re intricate tools that profit from the standard. They drive innovation. They add things, deprecate things, remove things. They should not live standards. Otherwise, their intricate innovation will stop.

    I’m hoping that the MicroProfile initiative will prefer a fresh gape at “standardization” in Java and prevent the “standard feature creep” that has happened in J2EE and later on in Java EE from happening. note Little’s comment on the topic looks precisely fancy it.

    Java Rock Star Adam Bien

    JAXenter: Considering the current state of Java EE, did they requisite an initiative fancy MicroProfile? Should Oracle prefer Part in this initiative?

    Adam Bien: Sure! Oracle is highly welcome.

    JAXenter: carry out you referee MicroProfile will absorb any impact on Java EE Guardians? 

    Adam Bien: Java EE Guardians is just another group of passionate Java EE fan girls and fan boys. I’m positive they esteem it. At least they retweeted everything what was microprofile.io-related.

    I will search information from the Java EE Guardians about their belief next time I catch the chance.

    JAXenter: Mike Croft said that the JCP involves more than just Oracle while Lukas Eder opined that the JCP is Oracle. What is your opinion?

    Adam Bien: I asked the question myself. I asked Heather VanCura What is the relation between JCP and Oracle? The confess can live institute here.

    Oracle has a permanent seat on the JCP Executive Committee (EC), and together with the other EC members, the EC votes on the work of the Expert Groups and evolves the JCP itself. The EC is led by a non-voting Chair from the PMO; the PMO is the group within Oracle that is accountable for administering the JCP and chairing the EC. The EC does not micro-manage the day-to-day workings of Expert Groups – the EC has the chance to review the work of each Expert Group at well-defined points as their specifications proceed through the JCP program. The primary duty of the EC is to ensure that specifications carry out not overlap or combat with one another and that the specifications meet the needs of the industry segment for which they are being written.

    Heather VanCura

    On the spec-level it is even clearer. Some specs JSR-365, CDI 2.0, Dependency Injection for Java, JSR 330 were / are led by other companies entirely without Oracle.

    More to come.

    The Benefits of Java EE5 | killexams.com true questions and Pass4sure dumps

    From its inception more than a decade ago, the Java platform has matured considerably making it the preferred election of many professionals & organizations for developing applications. In its most recent version for the enterprise -- dubbed Java EE 5 -- its designers absorb placed a special emphasis on doing more with less, so whether you're a seasoned expert or just starting out, it's likely you will find some fresh approaches that will simplify and ease your evolution efforts – this article takes a closer look.

    Annotations : Meta data & Descriptors POJO input validation Java EE 5 Pre Java EE 5 public class User { private String password; @MinLength(5) @MaxLength(20) public void setPassword(String password) { this.password = password; } public String getPassword() { recrudesce password; } } public class User { private String password; public void setPassword(String password) throws Exception { if ((newPassword != null) && (newPassword.length() > 20)) throw unusual Exception(); this.password = password; } public String getPassword() { recrudesce password; } }

    Meta data is a powerful programming concept, one which allows developers to specify or alter application code deportment outside of the actual programming logic. In prior Java enterprise versions, this was achieved through XML files known as deployment descriptors; however, while this allowed for such behavioral customizations, it forced even the simplest applications to fulfill such a requirement whether they needed meta data or not.

    In Java EE 5, meta data can now live embedded directly in application code -- a process known as credit programming. What was once required to live specified in additional XML descriptors can now live accomplished with in-line declarations, providing a more streamlined evolution process -- users of an open source Java project named XDoclet can probably relate to this concept.

    This is not to verbalize XML descriptors are obsolete in Java EE 5, they are noiseless very much valid. As a matter of fact, XML descriptors provide a secondary and overriding mechanism to any meta data that might absorb been declared within application code. In other words, a Java EE 5 application server will automatically prefer any deportment properties declared in a deployment descriptor over those embedded in Java byte-code.

    It should live pointed out that credit programming is not an exclusive addition to Java EE 5, but rather Part of the Java gauge edition 5(J2SE), an enhancement which cannot live underestimated, not only because gauge uphold for credit programming marks a shift in Java as a whole, but besides because many other areas pertaining to Java EE 5 -- not just deployment descriptors -- can live enhanced using this very principle.

    Annotations are very much open ended in terms of the functionality they can offer, making them example for pre-packaging any kind of Java logic that might absorb been considered tedious in earlier Java enterprise versions. To cite a concrete example, let's prefer the case of data validation. In prior Java versions, data validation either entailed a substantial amount of scaffolding code or an ad-hoc framework -- verbalize Struts -- to validate input. In Java EE 5, they can earn expend of Java annotations so their POJO's gape something fancy the following listing.

    Use of Entity API with O/R annotations @Entity(access=AccessType.FIELD) public class AddressBook { @Id(generate=GeneratorType.AUTO) long pk; @ManyToOne Owner own; @OneToMany(cascade=CascadeType.PERSIST) Set entries = unusual HashSet (); Date enteredDate; protected AddressBook() { } public AddressBook(Owner own) { this.own = own; } public void addEntry(Entry entry) { entries.add(entry); } public Set getEntries() { recrudesce entries; } public Owner getOwner() { recrudesce own; } public void enteredAddressBook() { enteredDate = unusual Date(); } }

    Each of the previous annotations represents a particular deportment in an O/R design, with the backing logic and relational data bridging being executed by a Java EE 5 compliant application server, which in turn, allows organizations to choose among best-of-breed implementations based on a common standard, a point that can live especially valuable to those who absorb dealt with the fragmented/proprietary syntax used by commercial O/R vendors -- fancy Coco foundation -- and open source projects such as Hibernate.

    Continuing with their discussion on the persistence API for EJB 3.0, another functionality that was factored into its design was the capacity to operate outside the context of Java EE containers, in upshot creating a universal purpose persistence API usable in gauge Java environments(J2SE). As a matter of fact, it is a confirmed possibility by Sun that this very persistence API will live spun out of EJB 3.0 into its own working group/JSR. But let's not stray too far away from their main theme on Java EE 5.

    Turning back to the previous code listing, you may absorb noticed they were dealing with a POJO, which is another addition to working with the gross gamut of components in EJB 3.0 -- not just entities, but besides the unusual incarnations for session beans and messaging beans. Among the main advantages of using POJO's in Java EE 5, are two factors which retract hand in hand: testing and simplicity.

    Once relegated to the biggest enterprise projects, testing has become an integral Part of the software evolution process with the popularity of agile principles; however, in the pre-3.0 EJB model, this process proved to live an elaborate endeavor at best. The reasons behind this complexity lied in both the container based environment required to execute EJB's and the inheritance hierarchy imposed by earlier versions.

    With a container needed to manage middleware services inherent to EJB's -- such as transactions and security -- this required the replication and bootstrapping of a similar container to test the industry logic behind an underlying EJB. And even though the expend of such a testing container was technically feasible, what proved to live an even more difficult job was the actual creation of tests for a given EJB. This was due to the close-knit design around such container services enforced through an inheritance hierarchy.

    In the pre-3.0 EJB world, every design was required to inherit deportment from an EJB foundation class to wire up middleware services. In Java EE 5 this requirement has been lifted, allowing the expend of POJO's to live enabled as EJB's and in this very process ease the creation of tests, achieving a very immaculate separation between the middleware service required for EJB's and the actual industry logic behind them. prefer a gape at the following listing which illustrates an EJB 3.0 session bean.

    Session bean POJO in EJB 3.0 @Stateless public class RateCalculator { public int add(int a, int b) { recrudesce a + b; } public int subtract(int a, int b) { recrudesce a - b; } public int multiply(int a, int b) { recrudesce a * b; } public int divide(int a, int b) { recrudesce a / b; } }

    Notice how they expend an annotation to wire up the EJB, but more importantly, how consummate of its methods are structured as a POJO, making the code testing process a simple step in the evolution life-cycle, and one which does not require intricate knowledge in setting up ancillary dependencies which were the norm in pre-3.0 EJB.

    Java EE 5 -- just fancy its predecessors -- besides has another major Part in its architecture, one related to technologies on the web tier.

    Web Tier : JSF and Co.

    The web tier in Java EE 5 has not changed as radically as its EJB counterpart from earlier versions, but there are a few issues worth mentioning, such as the formal incorporation of Java Server Faces(JSF) into the Java enterprise mix.

    Created as a means for standardizing UI components, handling navigation, input validation and page events for web applications, JSF has had various implementations and tools circulating since early 2004, but to many in those early days, the appearance of JSF came with a sense of too little, too late or simply too late. Since JSF was neither designed to live a web framework nor a substitute for core Java web technologies -- Java Server Pages(JSP) and Servlets -- it created a positive misconception around its use, given that many developers were either just snug with the productivity provided by core technologies -- JSP's & Servlets -- or simply saw overlap in JSF compared to many of the Java web frameworks that appeared earlier.

    With Java EE 5, JSF will officially live supported in every compliant application server, making it a powerful addition to the enterprise platform and a compelling one at that, especially with uphold for standardized UI components. With the appearance of web techniques fancy Asynchronous JavaScript and XML(AJAX), the bar for creating powerful web interfaces has only risen, so the capacity of mixing and matching pre-built UI components or Faces -- referee widgets -- will probably become even more attractive to many.

    Still, for those who may absorb worked with earlier JSF versions and experienced a positive combat with the principles established by JSP's as a presentation technology, the version behind Java EE 5 -- JSF 1.2 / JSR 220 -- is specifically designed to align these particular issues while noiseless remaining in-line with earlier JSF versions.

    As far as other Java enterprise web technologies are concerned -- namely JSP's, Servlets and JSTL -- with the exception of a few minor additions and revisions, there are no unusual surprises with respect to earlier versions.

    We absorb pretty much covered the major benefits behind Java EE 5, but they noiseless absorb one more issue to address, how to actually prefer edge of these features.
