Problems with Actitivi 5.9 and Web Service calls

[erny18031]

Hi.

Hi would like to use the standard BPMN way to call web services (no specific clients).

My BPMN is something like this:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" 
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Whenever I run the test (whithout activiti-cxf) I get :

org.activiti.engine.ActivitiException: Could not find importer for type http://schemas.xmlsoap.org/wsdl/ | diagrams/ProcesoEjemplo.bpmn20.xml | line 16 | column 50
Could not import item of type http://schemas.xmlsoap.org/wsdl/ | diagrams/ProcesoEjemplo.bpmn20.xml | line 16 | column 50
‍‍‍‍

When I include activiti-cxf, I get the following error:

java.lang.ClassCastException: com.sun.codemodel.JCodeModel$JReferencedClass cannot be cast to com.sun.codemodel.JDefinedClass
   at org.activiti.engine.impl.webservice.CxfWSDLImporter.importStructure(CxfWSDLImporter.java:152)

   at org.activiti.engine.impl.bpmn.parser.BpmnParse.parseImports(BpmnParse.java:310)

What do I wrong?

Thanx.

Hi,

Can you create a unit test that reproduces this error?

Best regards,

Hi,

I am trying to test a public webservice by invoking it from webservice task. I have modified the .bpmn xml with the entries.
could anyone share a example on how to invoke a public webservice and how to test it,

Also can we create 2 service task and link them to pass the output of 1 service as input to another.

I´m using the Activiti 5.10 and I have the same problem.
When I´m goint to deploy the process I get the error: "could not find importer for type http //schemas.xmlsoap.org/wsdl/"

I´ve attached the unit Test for this process, this page does not allow me to upload the files, so here we go…

Try adding activiti-cxf as a dependency, the webservice-parsing is handled by this class: org.activiti.engine.impl.webservice.CxfWSDLImporter
