[jira] Created: (ODE-841) Migrating BPEL Extension support to ODE
trunk
Migrating BPEL Extension support to ODE trunk
---------------------------------------------
Key: ODE-841
URL: https://issues.apache.org/jira/browse/ODE-841
Project: ODE
Issue Type: New Feature
Components: BPEL Runtime
Affects Versions: 1.3.4
Reporter: Milinda Lakmal Pathirage
Assignee: Milinda Lakmal Pathirage
Fix For: 1.3.5
Current trunk doesn't have BPEL extension support even though extension support is there on 2.x-experimental branch. Also when dealing with long running extensions like BPEL4People, it's hard implement that type of extensions with the current support provided by ODE 2.x-experimental branch. First we need to port extension support in 2.x-experimental branch to trunk and then improve the support for long running extensions.

Waruna Ranasinghe commented on ODE-841:
---------------------------------------
I have finished work on long running extensions.
I have introduced a new AbstractLongRunningExtensionOperation class.
The extender of the above class should implement 2 abstract methods.
One method is to invoke the long running external service or an equivalent
The other method is to do your work after receiving the response from the external service
I have also introduced AbstractExtensionCorreationFilter class. This class should be extended in-order to get the correlation values from the response message.
The implemented class should be mentioned in the ode-axis2.properties file (i.e. ode-axis2.extension.correlation.filter=class name)
The QName of the filter also should be mentioned in the deploy.xml file, so that the filter is used to add a correlation key to the the provide's partner link
<provide partnerLink="b4pPartnerLink" correlationFilter="filter:sampleFilter">
<service name="apprv:ClaimServiceCB" port="ClaimPortCB"/>
</provide>
I'll attach the patch asap.
comments and suggestions are welcome

Any estimates when this feature will be available, and in which version (1.3.5 I hope?)
Thanks for all your hard work!

---------------------------------
Let's do it via extension activity interface, since
1. it's a good idea to be able to implement other custom activities with similar capabilities
2. not make brick with everything for BpelRuntimeContextImpl

Milinda Lakmal Pathirage commented on ODE-841:
----------------------------------------------
While implementing BPEL4People extension on top of current extension infrastructure, I noticed that we must give the extension developer the advantage of JACOB and Channels.
For example, let's take BPEL4People scenario. Once BPEL engine invoke the task engine to create a task, BPEL process must go to a state where it waits for the response task engine without blocking any threads. And when the task is completed and when task engine send the notification to the process, process should start from the place where it waits for a response from task engine. this situation is same as one-way <invoke> followed by a <receive>. But we let the extension developer the chance to handle the selection of correct process instance.
After a quick hack, I was able to facilitate this by adding some extra attributes to deploy.xml provide configurations, changing integration layer, introducing new Channel and couple of other hacks to the BpelRuntimecontextImpl. But it's a very ugly hack and we should provide a better way of handling this situation by making the extension development and deployment mechanism more flexible.
We are still working on figuring out a better solution for this. It's really helpful if community can tell what they think about providing this kind of flexibility for BPEL extension development and if you guys have better alternative please feel free to comment on this.

--------------------------------------
Cool, thanks. No, the refactoring is not (yet) needed. It has been introduced to allow for having multiple OModels in parallel, but we don't have this yet in trunk and would also prefer an approach with less code duplications.
I remember that I actually wanted to change the extension validator part to become a extension compiler, but I think I can do this when merging your patch. Is the patch complete now (given the fact that we don't want to port the refactoring)?

Waruna Ranasinghe updated ODE-841:
----------------------------------
Attachment: ODE-841-complete.patch
This is the complete patch with extension support. (You may ignore the previous ODE-841.patch)
This includes the long running extensions as I have mentioned in the previous comment.

Hi all,
I started porting BPEL extension support to trunk.
For now, I have completed compilation part.
I will continue implementing rest of it as well.

----------------------------------
Attachment: ODE-841.patch
The patch is generated against revision 957131
I have included all the functionalities required for bpel extensions in to BpelRuntimeContextImpl.
But in the experimental branch (2.0), BpelRuntimeContextImpl class was re-factored in to BpelRuntimeContextImpl and RuntimeInstanceImpl. Do I need to do the same in the current trunk as well?
