Hi,
You are right. WSDL is a standard and it should work on what ever implementation that respects the specifications.
It might be a bug in the Activiti implementation using JAXB to do the XML mapping.
Making the same web service using CXF and not Axis was only a suggestion so that we can move forward in our analyses.
Between, i have never worked with Axis and i have never seen this JAXBElement exception …
I think that it is not trying to call the web service, but it is only trying to do the XML mapping from the wsdl … If only an Activiti cxf developer may confirm my supposition ..
Well, you should be able to call your web service without any problem (if it is the same SOAP version (1.1 /1.2 … ) and is JSR compliant …)
For example : Axis 1.0 is not compatible with 'JSR 222 Java Architecture for XML Binding (JAXB) 2.0'
Best Regards,
Atif
I was under the impression that it did not matter what tools were used to create a Service as long as it produced WSDL that accruately described it; and, if it did, clients written with any tool could call that Service. Am I mistaken? (After all, as you probably guessed, this is my first exposure to Web Services and my understanding may be quite naïve.)

Another question. Is Activiti Explorer trying to somehow call the Web Service at the time of deployment? This exception is happening when I try to deploy the BPMN20 file using Explorer (or using a test case to deploy).
I think that it is not trying to call the web service, but it is only trying to do the XML mapping from the wsdl … If only an Activiti cxf developer may confirm my supposition ..
If recreating the Web Service using only CXF gets me around the problem, will that mean that I will only be able to call from Activiti only those Web Services that were created using only CXF?

I am sorry it took me several days to learn enough about CXF to use it to rebuild my web service. Thank you for your patience.
I managed to have Eclipse create the Web Service using cxf. Then deploy the modified BPMN20.xml file that contained the Web Service Task.
I am, however, not able to start the Web Service Task. I start the process in Explorer, put data in the Start Task form, and then see the exception shown below. Would you please be able to look at my WSDL and BPMN20 files (shown below) to see what I have done wrong?
Before trying to invoke the web service via Activiti, I had Eclipse generate a client that calls the web service successfully. I moved the client to another PC in our network and it still called the web service (running on my desktop) successfully. I do not know if it will help, but I put a copy of the client generated by Eclipse below as well. I also included a copy of the Java class I used to have Eclipse create the web service.
