[JBoss jBPM] - problem reagarding task node configuration in jbpm - jbpm-users

Wednesday, 22 July 2009

Hi, 
    In my jbpm processdefinition I have configured a task node but on deployment of the
processdefinition.xml I am getting error as below

  | 14:35:40,281 ERROR [LoginAuthenticationFilter] org.hibernate.exception.DataException:
could not insert: [org.jbpm.taskmgmt.def.Task]

And the problem of this error is because of task node insert...If I alter my jpdl without
any tasknode configuration it will be deployed successfully without any problem...

Can anyone please tell me what can be root cause of the problem? It might be the prb wid
my hibernate.cfg.xml so for your reference I am sending you the same as below
