How to integrate JMS with JBPM

[sangram konde]

 Hello all,

   I want to implement JMS (any like RabbitMQ, ActiveMQ....) in JBPM.

   We are calling JBPM workflow from REST APIs.

   Basically when we do the API request for the workflow then it will have a queue for the workflow request on JBPM side. 

   I am also googling it but not getting the proper solutions.

   If anybody has worked on the same then please provide the suggestion for this. It will be very helpful.

   Thanks in advance!!!

could you elaborate more on what you need JMS for? Would you like to call jBPM over JMS instead of REST or you want to use JMS from within the process

OK....

        The current flow is..  

There are different workflows with respective to different APIs.

We have a java client in our API to call JBPM workflow which is deployed on JBPM server.

If we hit multiple request for the workflow using REST API then workflow runs simultaneously ( or asynchronously).

We don't want that functionality. 

What we need is that if we hit multiple request for workflow( may be different or same workflow ) then it should go into the queue and then it will run one by one

So, my requirement is to implement a queue using any JMS which will add request to the queue for consumer.

And I guess this functionality will reside and should be implemented on JBPM side itself.

It should be synchronous that means it will not go for the second request until and unless first request gets success.

As per my understanding ...

  Producer    - REST API

  Queue       - JMS queue (should be in JBPM)

  Consumer  - JBPM/Any other technologies.

Please guide me If I am in wrong direction.

Thanks,

darn.  I am on the same situation.  Did you get a solution?

such feature is out of the box available with KIE Server JMS support. Execution server (aka kie server) can be accessed via REST or JMS. See docs for more details.

As I understand from your post, you are looking for sequential execution like iteration. There is no control over sequence in JMS, as the purpose is message delivery. You may use multi task with sequential type.There are three types - parallel, sequential and looping. I hope you have list object to hold the iterative data. For proper assertion, need more details.
