Re: [rules-users] Drools, slf4j and Eclipse Error on DroolsTest.Java

This isn't my code. It's created when a Drools project is created in Eclipse. I guess that's why this is so frustrating. It's supposed to demonstrate a very simple Drools program and I can't get it to work. It's hard to debug someone else's code when you don't know the language yet. Code is kSession.insert(message); Thanks sdjoe [via Drools] wrote: > Hard to say without seeing your code.
