    Problem with very latest cvs checkout jbpm.3 on Windows and

    David Sanchez Novice

      Thought swithing platforms might help. Seems either I'm not connecting to the db at all or the schema isn't correct.

      fresh jboss-4.0.2
      fresh cvs of jbpm.3

      All these ant commands went fine.

      ant compile;ant build;ant build.processes
      ant -f build.deploy.xml create.db
      ant -f build.deploy.xml create.jbpm.configuration

      ant -f build.deploy.xml start.jboss...produced errors shown below.

      Also, do I really need to use "deploy.service.archive" and "deploy.webapp" If I use the above ant targets? It worked for me before not to need them.
