Error reconnecting SessionBean

zenix Mar 16, 2004 6:03 AM

Hello,
My tools:
JBoss 3.2.2
J2SDK 1.4.2_03
JBoss-IDE 1.2.3

I'm having problems reconnecting my CartBean from Delegate.

java.io.InvalidClassException: org.jboss.util.id.UID; local class incompatible: stream classdesc serialVersionUID = 4588799618105892224, local class serialVersionUID = -8093336932569424512

This error means that i have two versions off... what?

I don't have multiple Jboss versions.

Here's my .packagin-file:

Hi all,

I get the same error trying to recreate a Stateful Session EJBObject from a cached handle.

To re-read the object I use the following:

byte[] bytes = new String(id).getBytes();
java.io.ByteArrayInputStream io = new java.io.ByteArrayInputStream(bytes);
java.io.ObjectInputStream os = new java.io.ObjectInputStream(io);

javax.ejb.Handle handle = (javax.ejb.Handle)os.readObject();
return handle.getEJBObject();

Is there another way to retain the reference besides sticking the object itself into the httpSession?

TIA,

Graham
