I would like to build a GUI to define a Process Flow.
1. Does JBPM support that? NOt the Eclipse Plugin. Web-based?
2. Is there a out-of-the-box implementation of JBPM GUI?
3. Can I reuse, JPDL plugin as web-based GUI?
4. How can we use XPDL in JBPM?
2: Yes, the eclipse plugin
3: JPDL designer? No
4: Look at the PVM project. XPDL will be implemented on top of the PVM (process Virtual Machine) just like JPDL, BPEL, Seam-pageflow and possibly others
