I had generated the decisiontable using the eclipse plugin for drools 4.x. using the eclipse the DecisionsampleTest works fine but on running it from the command line gets the following error: org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule name=HelloWor com/sample/Rule_HelloWorld_11_0.java (8:411) : The method update(Decisio com/sample/Rule_HelloWorld_11_0.java (9:453) : The method update(Decisio at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:2 at com.sample.DecisionTableTest.readDecisionTable(DecisionTableTest.java
