Do I have to use the EMF? I just want to be able to serialize the Map that contain the sessions. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/643217#643217] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

That seems to work but sometimes I get the following error. I am not sure how that happens but it does when i try to resume a session. I a try the resume a second time it goes through without issue.
