Thanks for your reply.

 

  Please let me know if there is any thing I can help on jBPM 4.

 

  There are more and more people around me plaining to use jBPM for their project's process engine.  Beside a core processEngine, many people intend to use a complete BPM solution.  I think that is what jBPM5 aim to, see the BAM, Report(BI) and so and.

 

  And I am also agree the opinion of Sebastian that jBPM5 could use a popular DI container, like spring or guice, we needn't create a DI container by ourself. Then we could focus on ehancing the core process engine and related modules.

 

  In addition, it may be a wonderful thing if jBPM5 could support BPEL. the PVM definitely has ability to do this.  It will make the integartion from BPEL and BPMN more easier.
