[rules-users] Drools function not working with Javassist facts

[Ayush]

Laune,
Thank you a lot for your reply. Here I go explaining the code.

*I'm generating dynamic java objects. In this the class file is made once
and on each request we make a new instance and insert it in drools session*

    public Object getFact () 
		throws CannotCompileException, InstantiationException,
IllegalAccessException {

        if (msgClass != null) {
            return msgClass.newInstance ();
        } else {
            final ClassPool pool = ClassPool.getDefault ();
            CtClass msgCtClass = null;
            System.out.println ("creating new class...");
            msgCtClass = pool.makeClass ("drools.dynamic.Message");
            final CtField field = new CtField (CtClass.intType, "Count",
msgCtClass);
            field.setModifiers (Modifier.PRIVATE);
            msgCtClass.addField (field);

            final CtMethod getter = CtNewMethod.getter ("getCount", field);
            msgCtClass.addMethod (getter);

            final CtMethod setter = CtNewMethod.getter ("setCount", field);
            msgCtClass.addMethod (setter);

            msgClass = msgCtClass.toClass ();
            return msgClass.newInstance ();

           }
       }

*After getting the object I create drools knowledgebase and session*
     final Object obj = new FactGenerator ().getFact ();

        final KnowledgeBase knowledgeBase = createKnowledgeBase ();
        final StatefulKnowledgeSession session =
knowledgeBase.newStatefulKnowledgeSession ();
        try {
            // final Message msg = new Message ();
            // msg.setMessage ("Test message");
            // msg.setStatus (0);
            // session.insert (msg);

            session.insert (obj);
            System.out.println ("Firing rule...");
            final int count = session.fireAllRules ();
            System.out.println ("rules count: " + count);
        } finally {
            session.dispose ();
        }

*Here is the drl file I'm using *

import drools.dynamic.Message;

rule "Hello World"
	dialect "mvel"
	when
		$m : Message()
	then
		
		//System.out.println("count: "+$m.getCount());
		System.out.println("count: -999");
		//logMessage();
		//System.out.println("Message: "+message);
		
		retract($m);
		
end

function void logMessage() {
	
}
-----------------------------------

The above rule works perfect when I'm running it without the function
logMessage(). 
*Below are the jar files I'm using in project *

- antlr-2.7.7.jar
- antlr-3.3.jar
- antlr-runtime-3.3.jar
- drools-clips-5.3.0.Final.jar
- drools-compiler-5.3.1.Final.jar
- drools-core-5.3.0.Final.jar
- drools-transformer-jxls-5.1.0.M2.jar
- knowledge-api-5.3.0.Final.jar
- mvel2-2.1.0.drools14.jar
