PASSED Manual Testing using the following steps:

1. Use WebLogic 10.3.6.

2. Add jar file in WebLogic lib folder. ( commons-lang.jar, antlr.jar, mozilla jars)

3. We have to tell Weblogic to load portal/plugin JARs from WEB-INF and not by its original class loader. In weblogic.xml set prefer-web-inf-classes flag to true. This tells weblogic to load classes from web-inf folder first.

   <container-descriptor> <prefer-application-packages> <package-name>antlr.*</package-name> <package-name>org.mozilla.*</package-name> </prefer-application-packages> </container-descriptor>

4. Start the server.

5. Login liferay.

6. Deploy Plugins "OpenSocial plugin" and "kaleo-web plugin".

7. Check deploy the plugins is working.

Fixed on:

Tomcat 7.0 + MySQL 5. Portal 6.1.x EE GIT ID: 6698dc5c5f413f7a0b5c8abb544f68f9eb203551.
Tomcat 7.0 + MySQL 5. Portal 6.2.x GIT ID: ba03a80f588dcfccfaa674fe4dfbe872e32b35cf.

OpenSocial plugin and kaleo-web plugin work fine on the portal.

Committed on:
Portal 6.2.x GIT ID: c54c76c0f426d1f864589e8b5b5292a603a60d8f.

How to test this: simple remove PRE_CLASSPATH setting from setDomainEnv.cmd (if there is any) and try some of the related LPSs.

For example: to add OpenSocial plugin; or to approve web content using kaleo-web.
