[jboss-user] Null class exception

Hello, I have an ejb jar created with maven, and included in an EAR file. The EJB jar is very simple, just one DAO class. When I deploy the EAR I get this: 00:50:26,984 INFO [org.jboss.ejb3.deployers.Ejb3DependenciesDeployer] Encountered deployment AbstractVFSDeploymentContext@681086685{vfs:///opt/Programs/jboss-6.0.0.Final/server/default/deploy/intracore.ear/addblox-impl-1.0-SNAPSHOT.jar/} 00:50:27,040 WARN [org.jboss.ejb3.interceptor.InterceptorInfoRepository] EJBTHREE-1852: InterceptorInfoRepository is deprecated 00:50:27,254 WARN [org.jboss.ejb3.interceptor.InterceptorInfoRepository] EJBTHREE-1852: InterceptorInfoRepository is deprecated 00:50:27,261 WARN [org.jboss.ejb3.Ejb3AnnotationHandler] JBMETA-4: did not find any bean meta data for annotation bean UserService, will create some 00:50:27,711 ERROR [org.jboss.weld.integration.instantiator.RedirectingBeanInstantiatorDeployer] Error during undeploy: vfs:///opt/Programs/jboss-6.0.0.Final/server/default/deploy/intracore.ear/addblox-impl-1.0-SNAPSHOT.jar/: java.lang.IllegalStateException: Not installed: org.jboss.ejb.bean.instantiator/intracore/addblox-impl-1.0-SNAPSHOT/UserService at org.jboss.dependency.plugins.AbstractController.uninstall(AbstractController.java:790) [jboss-dependency.jar:2.2.0.GA] at org.jboss.dependency.plugins.AbstractController.uninstall(AbstractController.java:669) [jboss-dependency.jar:2.2.0.GA] I looked around and found few bugs with work around http://community.jboss.org/thread/160334 However the MANIFEST.MF file contains no MAIN-CLASS: at all. Any advice ? It's a bit urgent. Thank you.
