EJB Handles in jboss3.0 not Serializable?
Hi,
Redeploying a web app fails to reconstitute/persist EJB handles. Seeing as EJB handles are persistable proxies for EJB objects, this must be a bug surely. I've seen elsewhere on this forum that someone had similar troubles sending handles to Object output streams. I've only tried so far with the catalina container, but am pretty positive it's not a web container issue.
Simple code:
javax.ejb.Handle aHandle = someEJB.getHandle();
myHttpSession.setAttribute("gonnaLoseItHandle", aHandle);
Produces the following on restart:
