    Process Definition Location in a WAR File

    neilac333 Novice

      I am attempting to deploy a Seam app that utilizes JBPM. I have a single page definition file and a single process definition file. Both are located, for the time being, at the root of my WAR file, and both are in my components.xml file in the proper places (without slashes or anything).

      When I deploy my WAR to WebLogic 9.2, the page definition file is processed correctly, but the process definition file is not. I get a MalformedURLException when JBPM tries to find it. What can I do to ensure that the process definition file is located correctly? Why would one file be processed but not the other?

      Here is the log:

      As a corollary, I would like to put these files and others like them that come along in the future in their own directory relative to the root. Is this possible? How would I indicate that in components.xml?

      Thanks for your insight.

          Taj Newbie

          Hi,

          I get the same problem.

          The JBOSS classloader loads the process definition xml files using its custom class loader, for some reason it searches for the xml file with respect to the lib - jbpm-jpdl.jar. Place this jar in the WEB-INF/lib and then place your process definition xml files directly in the class folder under WEB-INF\classes.

          If you want to create your own folder, configure like this -

          Use

          pdSubProcess = processDefinition.parseXmlResource("<ownfolder>/processdefinition.xml");
          jbpmContext.deployProcessDefinition(pdSubProcess);


          and

          create the folder as

          WEB-INF\classes\ownfolder\processdefintion.xml

          I am not sure why this happens though.

          Refer http://www.jboss.com/index.html?module=bb&op=viewtopic&t=133773

          Cheers
