    11g Release 1 Patch Set 3 (WLS 10.3.4)

    763269
      Hi.

      While creating new server in OEPE Helios(11.1.1.6) I found that WLS 10.3.4 is available for selection. However I didnt find any information neither links to download it. Only 10.3.3 is available.

      When and where it is\would be available for download?

      Thanks

            frf,

            Hello, as part of the WebLogic 10.3.4 release on friday - we verified JPA 2.0 functionality for enterprise users using JPA as their persistence pattern. The main issues were JPA 2.0 XSD validation and JPA 2.0 container managed persistence unit injection.
            The details of the following post outline what happens out of the box and how JPA 2.0 can be officially enabled on JEE5 compliant WebLogic 10.3.4 install +(with or without the QWG8 patch)+
            In 10.3.3.0 you were required to use the FilteringClassLoader via the *<wls:prefer-application-packages>* addition to your application managed persistence unit - this workaround is now deprecated and not required in 10.3.4.0 for both application and container managed persistence contexts.
            Specifically we will start retesting EE applications using a SSB injected @PersistenceContext container managed JTA transactional JPA 2.0 persistence units with/without JPA 2.0 XSD elements.

            I verified the server and it is using SVN rev# *8635 from 6 Dec 2010* https://fisheye2.atlassian.com/changelog/eclipselink/?cs=8635
            Essentially in order to enable JPA 2.0 functionality on WebLogic 10.3.4 shipped on 14 Jan 2011 - you apply the QWG8 patch below or manually edit your server classpath to put the JPA 2.0 persistence specification API jar and the com.oracle.jpa2support_1.0.0.0_2-0.jar ahead of the other liibraries on the classpath.
            commEnv.cmd: line 67
            
            @rem Set BEA Home
            set BEA_HOME=C:\opt\wls1034r20110115
            @rem Enable JPA 2.0 functionality on WebLogic Server 10.3.4 with the following patch line for commEnv.cmd:67
            set PRE_CLASSPATH=%BEA_HOME%\modules\javax.persistence_1.0.0.0_2-0-0.jar;%BEA_HOME%\modules\com.oracle.jpa2support_1.0.0.0_2-0.jar
            Everything is shipped with WebLogic 10.3.4 but JPA 1.0 is enabled by default so that this JEE5 capable server is backwards compatible with JEE5/JPA1 out of the box. Without the above patch you will see the following.

            <15-Jan-2011 5:58:40 o'clock PM EST> <Info> <Management> <BEA-141107> <Version: WebLogic Server 10.3.4.0 Fri Dec 17 20:47:33 PST 2010 1384255 >

            We have the required bundles in the modules directory...
            javax.persistence_1.0.0.0_2-0-0.jar (upgraded from 1-0-2)
            org.eclipse.persistence_1.0.0.0_2-1.jar (upgraded from 2-0)

            A very quick test of a JPA 2.0 container managed app with the following persistence.xml in the ejb.jar works as detailed below.

            There are 3 issues we must check.
            1) JPA 2.0 XSD parsing errors: as expected there are no more JPA 2.0 schema parsing issues.
            2) New JPA 2.0 schema elements like the *<shared-cache-mode>NONE</shared-cache-mode>* element - this passes validation but we need to verify runtime functionality
            3) JPA 2.0 runtime API like a entityManager.getMetamodel(); call on the Servlet or Statless session bean
            4) JPA 2.0 weaving/instrumentation - Again we need to verify something like weaving of Entities contaiing lazy IndirectLists are weaved properly by the container.

            Note: All testing in this post is on a WebLogic 10.3.4.0 install out-of-the-box. The only modification I made was in creating a derby 10.5.3.0 JTA global datasource "localJTA" on the server - and drop a container managed JPA 2.0 app as an EAR in the autodeploy directory on the default user domain.

                    </properties>       
                </persistence-unit>
            For 3) we get the following exception out of the box on a servlet if we do not apply the above mentioned patch below - because the container defaults to Java EE 5 functionality - or JPA 1.0
            http://download.oracle.com/docs/cd/E18476_01/doc.220/e18480/weblogicchap.htm

            and(FrontController.java:346)

            or 3) The same exception if we try to run JPA 2.0 on the DI entityManager from the SSB in the EJB container classLoader
            javax.ejb.EJBException: EJB Exception: : java.lang.NoSuchMethodError: javax/persistence/EntityManager.getMetamodel()Ljavax/persistence/metamodel/Metamodel;

            We also get the Kodo/OpenJPA provider when we attempt to weave.

            Therefore there is still a little bit of configuration required.

            Enabling JPA2 support
            1) install the QWG8 patch, or
            2) manually add the com.oracle.jpa2support_1.0.0.0_2-0.jar ahead of the server classpath by following the instructions in the documentation at
            http://download.oracle.com/docs/cd/E17904_01/web.1111/e13720/using_toplink.htm#EJBAD1309
            or doing it manually by modifying the following line
            C:\opt\wls10340_pub110115\wlserver_10.3\common\bin\commEnv.cmd

We check this by either checking that our Entity is an instanceof org.eclipse.persistence.internal.weaving.PersistenceWeaved interface, or debug into the Entity and look for our bytcode instrumented weaved fields that start with _persistence*.  The question is - we need a weaved field or weaved function that was introduced for JPA 2.0

            com.oracle.jpa2support_1.0.0.0_2-0.jar forensics
            I had a look at the patch jar com.oracle.jpa2support_1.0.0.0_2-0.jar that WebLogic 10.3.4 ships with that allows installers to enable JPA 2.0 (JSR-317) support to superceed the default JPA 1.0 (JSR-220) support. It looks like the container proxy code for container managed EntityManagerFactory and EntityManager $Proxy objects has been updated so that a JPA 2.0 EntityManager $Proxy object get injected with the proper API level object via the InvocationHandlerFactory, FactoryInterceptor. The Query proxy has been updated as well. There is a fix for Kodo(OpenJPA) and OpenJPA related to the recent change and deprecation of certain functions of those providers. The EclipseLink JPA 2.0 provider (as the provider for TopLink) did not need weblogic changes beyond placing the JPA javax.peristence 2.0 specification jar higher on the classpath.

              This is great info, Michael -- thanks! Is there a Wiki or some central page with this and similar info so we don't have to search through forum posts for such critical info?

                Hi,
                Yes, you can start at the wiki for the open source EclipseLink project. In the context of WebLogic 10.3.4 - I can only speak to the (JSR-317) JPA 2.0 using the EclipseLink JPA provider as part of TopLink - you can navigate to the following EclipseLink JPA related pages. For other EE technologies in WebLogic and also JPA2 I would consult the official documentation links above to start.

                  Thanks, Michael. Since this is such a critical issue (ability to use JPA 2.0 on JavaEE 5 servers), it would be helpful for them to put a link on the main page to this. A big problem is you start using JPA 2.0-specific features, run unit tests, and think everything's OK, then find that you can't easily deploy against your JavaEE 5 server. It would be much better to know before you start experimenting that you're going to have issues (or at least a convoluted config) if you're stuck on < 10.3.4 (my company is stuck on 10.3.1).

                  I'd like to see a link for something like "IMPORTANT: Using JPA 2.0 on JavaEE 5 servers" on:
                  http://wiki.eclipse.org/EclipseLink
                  http://wiki.eclipse.org/EclipseLink/UserGuide

                  http://www.eclipse.org/eclipselink/jpa.php

                  Maybe it's overkill, but such explicit warnings would be a big help. Thanks!
