    jbpm webapp as a portlet

    Luca Faggioli Newbie

      Hi all!

      I'm trying to integrate jBPM into JBoss-Portal, that is, I'm trying to change the jbpm webapp into a portlet.
      Has anyone already tried that and succeded?

      When I try to reach the first page, I get an error and this is how my server log looks like
