Hai
  I was also facing the same issue and your replay was helpful and 
i have added droolsjbpm-ide-common-5.2.0.M2.jar to the class path of my
project as you suggested .But i am getting
 the following exception.

java.lang.IllegalStateException: java.lang.reflect.InvocationTargetException

Any help would be appreciated.

Hi,

If it is not the case already, could you try adding the 
drools-ide-common jar (along with its dependencies) to the classpath 
of your project?

Best regards,

Bruno.

Hi,

I've been experimenting with the Guided Rule Editor plug-in in 
Eclipse.  I've built a Drools Project using the default Hello World 
sample application.  I've created a new Guided Rule in my project 
called GuidedRule.brl and get the associated drools.package with 
it.  The rule is simple:


WHEN

THEN

  System.out.println(Rule has fired);

I build the knowledge base as follows:

   * private** static* KnowledgeBase readKnowledgeBase()* throws* 
Exception {


KnowledgeBuilder kbuilder = 
KnowledgeBuilderFactory./newKnowledgeBuilder/();



kbuilder.add(ResourceFactory./newClassPathResource/(SampleGuided.drl), 
ResourceType./BRL/);


KnowledgeBuilderErrors errors = kbuilder.getErrors();

   * if* (errors.size()  0) {

   * for* (KnowledgeBuilderError error: errors) {

System./err/.println(error);

}

   * throw** new* IllegalArgumentException(Could 
not parse knowledge.);


}

KnowledgeBase kbase = 
KnowledgeBaseFactory./newKnowledgeBase/();



kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());


   * return* kbase;

}

The only line changed is adding the resource of type BRL.

When I try to run, I get the following error:

I've tried variations to add the drools.package as a PKG type, I've 
had the rules (and package) in both com.sample and /src/main/rules, 
but I can't seem to resolve the problem.  drools.package has been 
updated to include the package name (package com.sample;) and I import 
the message class as well (even though it isn't being used currently).


I suspect the issue is simple, but I haven't been able to figure it 
out.  Any help would be appreciated.
