java.lang.IllegalArgumentException: Could not find message
Hi,
I haven't much experience in the field jBPM and I am new to the community. I've been trying to implement a project using WSDL in the JBoss jBPM since few days. However, I always get the following error message:
java.lang.IllegalArgumentException: Could not find message

Does anyone know what could be the problem maybe. The process has just 2 service task, which call two operations in the WSDL. The XML process definition is:
