Can't find a persistence unit named
Hi All,
I am a newbie to ejb3. For my learning , i created a ejb application with a stateless session bean , a pojo class , a persistence.xml file with hibernate as persistence provider , postgresql as DB and jboss server 5.0.0 CR2.
The external jar added are ejb3-persistence.jar , hibernate-core and hibernate-entitymanager.jar
When i start jboss server , the following error is displayed
ERROR [AbstractKernelController] Error installing to Real: name=vfszip:/E:/software%20download/jboss-5.0.0.CR2-jdk6/jboss-5.0.0.CR2/server/default/deploy/Chapter3.jar state=PreReal mode=Manual requiredState=Real

I have tried other solution like removing the class-path from manifest file but same result is displayed.
Any help is appreciated
