NoClassDefFoundError: com/opensymphony/workflow/loader/AbstractWorkflowFactory

I wrote a custom WorkflowFactory and make it works in a test environment.

Using the same config inside a web application it throws a strange NoClassDefFoundError

java.lang.NoClassDefFoundError: com/opensymphony/workflow/loader/AbstractWorkflowFactory

Don't stay hours  (as I did) looking for class-path issues. It's not ClassNotFoundException but NoClassDefFoundError and I'm quite sure that class-path is correct.

Any ideas?
