I have an processdefinition in which each node needs a ActionHandler with a particular implementation. To make it cleaner I have an Abstract class that implements the ActionHandler and each of the handler for the node extends it. Now when I run this definition keeping the abstract class as part of the par file, everything seems to work fine. But if I moved the abstract class into a common.jar and have the processdefinition access it during runtime, its throwing classdefnotfound exception for executioncontext. Any thoughts, how I can abstract the repeating code into a separate jar that can be accessed by the definitions.
