[rules-users] Trying to get Eclipse Java code to call Guvnor

I'm using the example code from the Red Hat Magazine - http://magazine.redhat.com/2008/08/12/jboss-drools-how-to-tuning-guvnor- part-1/ - to try to get the sample code to work, but I keep getting the following error: Exception in thread "main" java.lang.NullPointerException at java.util.Properties$LineReader.readLine(Unknown Source) at java.util.Properties.load0(Unknown Source) at java.util.Properties.load(Unknown Source) at org.drools.agent.RuleAgent.loadFromProperties(RuleAgent.java:299) at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:256) at test.GuvnorTest.main(GuvnorTest.java:15) It appears to be unable to find my 'Guvnor.properties' file, but I have it in the classpath (I actually have it in several different places on my C: drive as I tried to figure out why it couldn't find it). Does anyone have any thoughts on what's wrong here? I'd appreciate any guidance. It seems like this should be a simple answer but I haven't been able to figure it out.
