    has jBPM/jPDL all capabilities of BPEL

    Younes Yahyaoui Novice

      Hi,

       

      i want to know if jBPM/jPDL has the same capabilites of BPEL. For example has jBPM the capabilites to model repeatuntil or scope or pick (which exist in BPEL).

       

      i have read that it is possible in jBPM to  write my custom node ? how to do this (any example or documentation )

       

       

      Thanks in advance

          Hi Younes,

           

          If you want to achieve repeat,  you could use decision to emulate.

          <state name='start state'>
            <transition to='decision  repeat'/>
          </state>
          <decision  name='decisoin repeat' expr='#{repeat}>
            <transition  name='repeat' to='start state'/>
            <transition  name='continue' to='continue'/>
          </decision>
          <state  name='continue'/>

           

          And I think you could use sub-process or group to emulate scope.

           

          There is no activity equals with Pick/Recieve for BPEL.  You could put a state to let process instance turn into wait state, then if there is some message come in, you could invoke executionService.signalExecutionById() to let process instance continue.
