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.v200805140145 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 ?
I'm afraid I don't depend on IDE support for my EJB3 needs - I just work with the code directly. But I believe that Oracle just announced a new bundling of Eclipse with plugins to support their technologies. You might try it.
Sometimes the only way things ever got fixed is because people became uncomfortable.
