I'm sure there will be restrictions on the architecture designs that can be constructed in some cases.
But this is at least a step forward towards JPA 2.0 in PS2 with application managed JPA utilizing EclipseLink 2.0.
The container managed support for JPA 2.0 will be in a subsequent patchset.
If you take a look at the analysis on the EclipseLink website for using JPA 2.0 with WLS, you may see some other alternatives. These would not be supported, but may offer you some options if you want to explore yourself.

i have a project JPA (hibernate provider) base that i can deploy in two formats:
2) portlet in a container porlet, for example liferay.
if my project JPA is deployed like application my persistence.xml is read perfectly and my app works ok!
if my project JPS is deployed like porlet my persistence is junked or bypassed and In the screen is appeared the next message:
<openjpa-1.1.1-SNAPSHOT-r422266:807362 fatal user error> org.apache.openjpa.pers
istence.ArgumentException: A JDBC Driver or DataSource class name must be specif
ied in the ConnectionDriverName property.
i understand that my persistence.xml isn´t reading!!
In tomcat server runs like applications and porlet, i think that i have a problem when app runs in weblogic 10.3.2 + liferay 5.2.3 like porlet... because i´m sure that my persistence.xml is bypassed!!!!
i need help! thanks guys!!!
For 10.3.2.0 (EclipseLink 1.2) and 10.3.3.0 (EclipseLink 2.0) the recommended approach is still option 3 - for a no-server-mod version.
However, on this page are other options including container managed scenarios with their own issues that involve modifying the server classpath directly like...
The page will be modified immediately after any subsequent version of WebLogic is out.

See the recent OTN post from 20110115 detailing the latest release of Oracle WebLogic Server and some retesting of the previous issues related to JSR-317 JPA 2.0 support below.
Re: Deploy Hibernate based EAR file on Weblogic 10.3.3?
The latest release of Oracle WebLogic Server has been available on OTN at the following location since 20110115.
This release provides support for JSR-317 JPA 2.0 container managed applications using the QWG8 patch or a manual prepending classpath change.
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 as well as the persistence.xml renaming one is now fully deprecated and not required in 10.3.4.0 for both application and container managed persistence contexts.
As of 20110115 the 5 outstanding issues below look to be fixed by applying the http://download.oracle.com/docs/cd/E17904_01/web.1111/e13720/using_toplink.htm#EJBAD1309 patch for QWG8 or manually prepending to the WebLogic 10.3.4.0 server classpath.

A JPA 2.0 EE application using EclipseLink as the JPA2 persistence provider on WebLogic is detailed in the analysis section below1) JPA 2.0 XSD parsing - verified
2) New JPA 2.0 schema elements like <shared-cache-mode>NONE</shared-cache-mode> - verified
3) JPA 2.0 runtime API like a entityManager.getMetamodel(); call on the Servlet or Stateless session bean - verified
4) JPA 2.0 weaving/instrumentation - this will require a more detailed lazy model and more debugging to fully verify
5) Dependency Injection of a container managed JPA 2.0 entityManager on a EJB component like a stateless session bean - verified
