Hi,

Closing the database context failed: An exception of type org.jbpm.JbpmException was thrown, with the message: problem closing services {persistence=org.jbpm.persistence.JbpmPersistenceException: hibernate commit failed} 

A more detailed stack trace is provided by the appserver (jboss 4.2.0.GA) :
