Im using the example code from the Red Hat Magazine - - 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(

        at org.drools.agent.RuleAgent.newRuleAgent(

        at test.GuvnorTest.main(

It appears to be unable to find my 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 couldnt find it).  Does anyone have any thoughts on whats wrong here?

Id appreciate any guidance.  It seems like this should be a simple answer but I havent been able to figure it out.
