Triggering BPM process wsdl from EJB in CE 7.2

Hi all,

I have a BPM process that has a start message trigger. I am trying to trigger this process from an EJB. and finally the EJB would be exposed as a web service.

The steps that I followed for the same:

-> I copied the URL of the WSDL (start trigger) from Configuration Mgmt -> Process Repository -> Select the process and choose 'Start Process' . The WSDL URL appears in the bottom table.

-> I imported the WSDL into an EJB module DC. Right click , Import WSDL. I could see 3 wsdl files in my DC. One with the name rootwsdl_TriggerDummyProcess.wsdl, the other 2 are rootwsdl_importedwsdl_1_TriggerDummyProcess.wsdl and rootwsdl_importedwsdl_2_TriggerDummyProcess.wsdl.

-> The wsdl that has the start trigger's location is rootwsdl_TriggerDummyProcess.wsdl. I created a web service client for this WSDL using the wizard.

-> I cretaed a session bean and wrote the code in the attached text file to execute the WSDL. The host and port are removed in this attachment.

-> I used the wizard to expsoe the EJB as a web service

->Now when I try to execute this web service, I get the below exception

Caused by: java.io.IOException: Server returned HTTP response code: 405 for URL: http://<host>:<port>/bpm/demosapcom/testbpm/DummyProcessTrigger

Can someone please advise how to go abotu resolving this?

Thanks in advance

Hi Subathra,

I have to ask, why would you want to wrap the BPM Start WS in a further layer in the form of an EJB? If you want to trigger the start of a BPM process as a WS, why not just call the BPM Start WS directly? I'm basically unclear on what you are trying to do and why - maybe give a bit more information on this and we can help more.

Gareth.

  Hi Gareth,
  
  I have just stated part of the requirement in here. The BPM process has to be triggered from the EJB as part of an end-to-end scenario.

      Hi Jun Wu,
      
      We need to execute a web service from EJB. The web service would invoke BRM rules. As you mentioned, it is as per our design. As a start, we are trying to invoke a sample web service, which in this case is the BPM process WSDL. Any case, I would like to know the cause of the error. What is that I am missing.
      
      Thanks

        Still cannot understand why you have to put those call in ejb.
        For wsdl URL, better get it from service registry.
