[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:
   
      
      
   
I could change it to:
-----------
import ..\sca\ConsumerFacade.composite
...
   
      <action sca-component-reference="RequestParser"/>
      
   
-----------
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
