Deployment of a process with a web service task

[chris_joelly]

Hello,

i tried to create a simple process using a webservice which works fine with a Java client,
but when i integrate it in a bpmn process the deployer throws the following exception:

Caused by: org.activiti.engine.ActivitiException: Could not find importer for type http://schemas.xmlsoap.org/wsdl/ | webservice-task.bpmn20.xml | line 24 | column 52
Could not import item of type http://schemas.xmlsoap.org/wsdl/ | webservice-task.bpmn20.xml | line 24 | column 52

i studied the user guide and the CXF samples but i can not see the problem. Is there some
confusion how i define the mappings? Initially i got some errors because i did not understand
the mapping definition in the process definition well, but these problems seem to be fixed now.

Thanks in advance

Can't see the problem looking at yuour process.
Can you create a simple unit test for it, so I can test it myself?
