Problems with Actitivi 5.9 and Web Service calls

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"?>

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
