Ok, but more info would be helpful. You say jbpm is agnostic to the environment. Are these the core libraries:
http://community.jboss.org/thread/PicExportError jbpm-flow
http://community.jboss.org/thread/PicExportError jbpm-flow-builder
http://community.jboss.org/thread/PicExportError jbpm-bpmn2
And, does any documentation exist that explains the various "other" non-jboss deployments (just core, core + tools, etc...)?
