But the result of the endeavor is just as before. Not surprisingly I can pick up the proxy (local IF) from the session in my ImageServlet successfully. But once I try to access a method, at the first time Seam is complaining like this: Caused by: org.jboss.seam.RequiredException: @In attribute requires non-null value: shopTree.applicationUser | However, I have verified that the field applicationUser is available in the Seam context. Moreover, I have debugged the Seam action-method which is implemented in the same SFSB and verified that the field has already been populated on a previous request. At the second request to the ImageServlet, I am getting javax.ejb.NoSuchEJBException: Could not find stateful bean: a4i810-vbn2mr-f8u25ljn-1-f8u49lh5-12 My only explanation is that JBoss' JNDI-implementation delivers a serialized instance (copy) of the original instance that is available in the EJB-container. However, AFAIK, this would not fit with the JBoss' specification, which says that JNDI-lookups for local IF's (in the same VM) result in a reference to the instance, not in a serialized copy. Anymore hint for me? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4103416#...
