<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>( 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?) </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I used JBOSS 4.2.3, a MySQL Database and Eclipse 3.6.x. It would be really great if someone could help me.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>javax.persistence.PersistenceException: java.lang.IllegalArgumentException:
