I have an RCP application that uses Jess and have added code to switch to JBoss. I can create a sample rules project in Eclipse, but when I simply move the rules and the Java source from the JBoss rules project into my RCP, I get extensive errors. I have added the JBoss builder and the JBoss dependencies to the build path. I get extensive errors when I merely try to open, edit, or save the drl file, but I tried to run the code anyway. I guess basic question is how to add JBoss rules to an existing RCP project.

When the code is executed, it obviously opens the rules because the errors that I get indicate it has opened it. Here is the exception trace.
