[jboss-user] [JBoss jBPM] - Re: jpdl and sca tuscany integration - any?

[Radu3000]

Tom,

Thanks for your reply.

In the end it boils down to the age old question: what is first chicken or the egg?  Process importing components or components importing process.

Let's take the approach of process importing components - chicken first.  Given the current process fragment:
<node name="Parse service request">
  |       <action class="com.bofa.crme.gps.servlet.RequestParserImpl"/>
  |       <transition name="next" to="Transform GCIB request to WCC request"/>
  |    </node>
I could change it to:

import ..\sca\ConsumerFacade.composite
  | ...
  |    <node name="Parse service request">
  |       <action sca-component-reference="RequestParser"/>
  |       <transition name="next" to="Transform GCIB request to WCC request"/>
  |    </node>

And done! Isn't this a cleaner separation of process and assmbly responsibility?  With a bit more work to integrate an sca tuscany runtime and jpdl runtime - there is so much to gain!  JPDL can tap into any (almost any - sca component types are constantly growing ...) type of components defined in sca.   The component impls would also implement ActionHandler - easy right?  

The SCA api is straight forward:
// line below can be triggered by the above 
  | // "import ..\sca\ConsumerFacade.composite" statment
  |         scaDomain = SCADomain.newInstance("ConsumerFacade.composite");
  | 
  | // line below is triggered when you need the action to be executed
  |         requestParserService = scaDomain.getService(RequestParserImpl.class, "RequstParserComponent");

So what is left?  
1. Change jpdl schema to allow:
      <action sca-component-reference="RequestParser"/>
2. Make some room in jpdl api to allow references to scaDomain.getService(...) calls.

I would be glad to contribute some time to the above.

Regards,
Radu Marian
