Re: [rules-users] RuntimeDroolsException: Unable to load

Hello Edson,Eric was kind enough to reply that he "solved" his problem by including ALL of the jars in the drools lib distribution directory in his classpath -- not just the drools jars, mvel, and eclipse jars. If I do this, JBoss 4.2.1 complains about not being able to parse its xml configuration files, so I'm narrowing the jars I'm including to see if I can isolate what's missing.

I will dig down to find the problem and we can have an answer available to all. This is for sure a classpath problem, so just a matter of finding out exactly what is missing.
