[rules-issues] Error while invoking Guvnor Rule from DRools project

Hi, We are trying to invoke Guvnor rule(drools-5.0.0.M1-guvnor) from a Drools project. For creating the rule in Guvnor, following steps were followed: 1) Created a category through Guvnor UI 2) Created a Package named "myNewPackage" under that category. 3) Created and imported a model to this package by uploading it through Guvnor. 4) Created a Rule with myNewPakage as the destination package. 5) Validated and saved the rule and built the package. Attached is the Java code for invoking the above created Guvnor rule from a Drools project. We are getting the following error while running the Java code: RuleAgent(default) INFO (Fri Jan 16 19:11:21 IST 2009): Configuring with newInstance=false, secondsToRefresh=-1 RuleAgent(default) INFO (Fri Jan 16 19:11:21 IST 2009): Configuring package provider : URLScanner monitoring URLs: http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/myN ewPackage/LATEST RuleAgent(default) EXCEPTION (Fri Jan 16 19:11:26 IST 2009): null.
