I am getting the following exception trying to deploy a jar containing
three beans, the first one being Guest/GuestBean/GuestHome.
[Container factory] Binding an EJBReference Guest
[Container factory] Binding Guest to internal JNDI source:
org.gaws.guestbook.entitybeans.GuestBean
[Container factory] java.lang.NullPointerException
[Container factory] at
org.jboss.ejb.Container.setupEnvironment(Container.java:405)
va:405)
[Container factory] at
org.jboss.ejb.Container.init(Container.java:264)
I am using a MySQL DB for the entity persistence and THINK I have it
setup correctly. It seems to load the driver and create the Minerva
pool just fine.
Any help would be greatly appreciated.
Thanks,
Garret
