I am running it fine on 4.0.2. There are just slightly different deployment instructions.
some people have reported problems with 4.0.2 and WARs referencing EJB3's. We haven't had the cycles yet to determine whether this is user error or our error.
jlward4 can you please post deployment instruction as i am struggling to get ejb3.0 Entity bean example running on jboss4.0.2.
By the way, I thought there were no desployment descriptors for ejb3.0
