[rules-users] Drools Compile Error

Hi, I have a rule that looks like this : package com.sample rule "Inner Class Test" when com.sample.OuterClass.InnerClass.InnerInnerClass( ) then System.out.println( "" ); end The inner class referenced by this rule is defined like this: package com.sample; public class OuterClass { public class InnerClass { public class InnerInnerClass { } } } I am getting an error "Unable to resolve ObjectType ' com.sample.OuterClass.InnerClass.InnerInnerClass'". What am I doing wrong? I am using XMLBeans-generated POJOs in my application and these POJOS contain a lot of deeply nested inner classes and these are giving me compile-errors in Drools. Thanks, Narendra
