User development, A new message was posted in the thread "mysql and JBPM Integration Problem": http://community.jboss.org/message/520684#520684 Author : null null Profile : http://community.jboss.org/people/ranjix Message: -------------------------------------------------------------- thanks Ronald, I can only assume that the original poster encountered the error while playing with the jBPM and then believing it was related. I personally ran into the issue while running the "all" configuration of the JBOSS AS and after I tried to configure some MDBs (so, as far as I know, unrelated to jBPM). Since the original post was in this section of forum, I put my question here as well...            postOffice = (PostOffice)JMXAccessor.getJMXAttributeOverSecurity(getServer(), postOfficeObjectName, "Instance"); in the ServerPeer class (line 1377) returns null. More debugging when I can get back to this, hopefully soon... ranjix -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/520684#520684
