has jBPM/jPDL all capabilities of BPEL

[ingedeut]

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.
