Process Definition Location in a WAR File

[darthmaul]

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?

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.

Looking at the Todo and DVDStore examples, the deployments are EAR files.  The docs only make mention of an EAR deployment as well.  Does this mean that I can use JBPM with Seam only when deploying to an EAR?

Thanks.

Nothing to do with not finding the file but some parsing error of your jpdl.

[harpritt]

I just got this one.

1) check the reference to yout Jpdl process definition is corect in your components.xml

2) make sure the process diagram is correct.....mine was jibberish the first time round. Do this - nick the process definition from the DVD example.

Im happy again.
