Problems with web services task!

Question asked by massimosassi on Mar 31, 2014
Latest reply on Aug 27, 2014 by fahad1
Hello, I’m trying to implement a web service task with activiti but I'm not able to solve a problem.

I'm following examples in “activiti in action book” and in the “cxf-module SimplisticDataFlow” example on the github activiti repository (https://github.com/Activiti/Activiti/tree/master/modules/activiti-cxf)

I want to call a simple external web service (http://webservices.daehosting.com/services/isbnservice.wso?WSDL ) but when I try to run a Unit test I have always  the following error (Failure Trace)

I’ve also tried with other simple external web service but I have always the same error.
When the process start the “web service task” the error appears. 

Could you help me ? Any Idea about how to proceed ?
Thanks in advance for your help !!!
