Eclipse support for EJB 3 on OC4J

Hi there!
I'm having some trouble trying to create a new EJB project with Eclipse 3.4(Ganymede) using Oracle OC4J Standalone 10.1.3 because in the EJB Module Version there is no option for 3.0 version. Although OC4J is J2EE 1.4 compliant, Oracle states(in official documentation) that it also has EJB3 support.
I've tried changing the plugin.xml file in folder [ECLIPSE_HOME]/plugins/org.eclipse.jst.server.generic.oc4j_1.5.205.v20080 5140145 to add 3.0 version to the supported versions but than I get a NullPointer Exception when trying to publish it.

Does someone have experience in using these technologies in Eclipse, or should I really consider using Oracle JDeveloper :( ?

Even i am also facing the same problem. any solution please
