Hi,

I try to get my own process running in the jbpm-console. I build a package via guvnor, this performs successfully.  Afterwards, i try to run this process, the Process starts but aborted  when its ended with a HTTP 500 exception. I looked into the log file and found the following exception:

( The jboss told me that he cant store the instance object. Why? And how it is possible to store a process correctly or how can i avoid storing a process?) 

I used JBOSS 4.2.3, a MySQL Database and Eclipse 3.6.x. It would be really great if someone could help me.

javax.persistence.PersistenceException: java.lang.IllegalArgumentException: IOException while storing process instance 2: java.lang.Object
