I wonder how I can depoly a webservice task in the activiti explorer

alexpiero

Afiter I import the bpmn20.xml of a webservice task in the Activiti Explorer, I press the deploy button but it turns out :

One of the attributes 'class', 'delegateExpression', 'type', 'operation', or "expression" is mandatory on serviceTask.

How can I solve this problem with the Activiti Explorer?
I would appreciate a lot if anyone can help.

Please post you process xml to see why it goes wrong.

Thanks a lot for your reply.
I just use the test process definition xml in the source code of activiti-master 5.14:

Thank you very much!

I can't reproduce this issue. When I deploy this process definition in the Activiti Explorer I get the message that it can't parse the WSDL schema. And that's because the activiti-cxf module is not part of the Activiti Explorer by default. Did you copy the activity-cxf module manually?

Best regards,

alexpiero

Thanks for your reply!
I have added the activiti-cxf.jar to the location of Activiti Explorer: C:\Program Files\Java\apache-tomcat-7.0.39\webapps\activiti-explorer\WEB-INF\lib
Is there anything wrong with my operation?
Would you please add the activiti-cxf.jar manually and try again with my process definition xml?
I'm waiting for your outcome and thank you very much!
