    dynamic endpoint

    Alex B Newbie

      Hi everyone!

       

      Please help!

      I managed to make a BPEL process that starts with receiving a parameter, then invoking a webservice that returns a wsdl url according to this parameter. Next I need to invoke the webservice who's wsdl was returned on previous step. So, my wsdl url is dynamic.

      How to assign the returned wsdl url to webservice invokation?  How is it possible to invoke a webservice with dynamic endpoint?

      I tried to assign the received wsdl url to partnerlink of invoked webservice, but it didn't work. Guess it is needed to do some more things...

      Could you give me an example? I found some on Apache ODE site, but it didn't work.

       

      I'm using BPEL Designer in Eclipse

       

      Thanks!

          Hi Alex

           

          Riftsaw does not have such an example. Are you saying that you have tried the DynPartner example from the Apache ODE project, and it does not work in RiftSaw?

           

          It might be a bug, so if you know the example works fine in Apache ODE 1.3.4, but not in RiftSaw, then can you raise a bug in the riftsaw jira attaching the relevant example (or referencing it if the Apache ODE one) and including info on the riftsaw/jbossas/esb version you are using and environment details?

           

          Regards

          Gary

            Any luck with this?

            I've directly adapted the ODE example to my simple test case and can't get this to work. Specifically, I use the  'Simple URL without wrapper' option discussed here: http://ode.apache.org/endpoint-references.html and used in the DynPartner sample, and get this error when the WSDL SOAP location does not match the statically assigned address:

             

            18:26:32,954 ERROR [DispatchImpl] Cannot dispatch message

            ...

                    at org.jboss.ws.core.soap.SOAPMessageUnMarshallerHTTP.read(SOAPMessageUnMarshallerHTTP.java:75)

             

            Also, when I try copying the original endpoint ref (which appears legal according to the BPEL spec) with:

            <bpel:copy>

              <bpel:from partnerLink="responderPartnerLink" endpointReference="partnerRole"/>

              <bpel:to variable="epRef"/>

            </bpel:copy>

             

            I get a long string of exceptions starting with:

            I'm going to start trying this with OSE in Tomcat next.

              Sure enough, both of these behaviors work fine in ODE running on Tomcat. I'm going to write up Jira issues for each separately. Dynamic endpoints are a critical capability for my application.
