    derek lee Newbie

      Hi , guys

        i integrated jBPM with spring just following /devguide/html_single/index.html#springIntegration.

       

      import jbpm.tx.spring.cfg.xml , then configurate springHepler and processEngine. however,it throwed out  exception as follow:

      i think that because i didn't configurate a sessionFactory in the file applicationContext.xml. but if i configurate a sessionFactory, then i should also configurate a dataSource  and  the property like mappingResources for it. we have the dataSource and the  mappingResources content in jbpm.hibernate.cfg.xml already. so do we need to configurate these content again? or maybe i walk on a wrong way.

       

      anyone can help?

       

      Thanks
