Before I start shouting "CRIITICAL BUG" is there anything I should check in
relation
to configuration of jboss that may cause the problem:
The following code snippet inside the stateless session bean SimpleSessionBean:
System.out.println("Looking up referance");
Object ref = jndiContext.lookup("CategoryBean");
System.out.println("Got reference");
CategoryHome home = (CategoryHome)
PortableRemoteObject.narrow (ref, CategoryHome.class);
Category cat = home.create("xxx");
System.out.println(cat.getCategoryID());
cat.remove();
home.create("xxx");
produces the following error in jBoss (latest CVS)
