[rules-users] Drools as osgi bundle in Jboss AS

[km.sujeet]

Hi, 

I am trying to run "Hello World" using drools as osgi bundle in Jboss AS.
Deployed below jars  to Jboss container :

drools-compiler-6.0.0.Beta1.jar
drools-core-6.0.0.Beta1.jar
drools-templates-6.0.0.Beta1.jar
kie-api-6.0.0.Beta1.jar
kie-internal-6.0.0.beta1.jar

While deploying my own bundle to Jboss which has "Hello World" Drools
application, I get below exception:

Caused by: org.drools.RuntimeDroolsException: Unable to load dialect
'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'

Then added "org.eclipse.jdt.core_3.8.3.v20130121-145325.jar" to classpath of
OSGI bundle (Hello World Bundle) and deployed again.

Above exception has got resolved, but application is not working.
Code below :

public void start(){
		
		logger.info("started.");
		System.out.println("Hello World in client!! ");
		
		//droolsSession = createKnowledgeSession();
		
		MessageTest message = new MessageTest();
        
        message.setMessage("Testing Hello World");
        message.setStatus(MessageTest.HELLO);
        
        droolsSession.insert(message);
        droolsSession.fireAllRules();		
		
		
	}
	
	@SuppressWarnings("deprecation")
	private StatefulKnowledgeSession createKnowledgeSession() {
		System.out.println("Inside createKnowledgeSession!! ");
		KnowledgeBuilderFactoryServiceImpl knowledgeBuilderFactoryServiceImpl  =
new KnowledgeBuilderFactoryServiceImpl();
        KnowledgeBuilder kbuilder =
knowledgeBuilderFactoryServiceImpl.newKnowledgeBuilder();
        kbuilder.add((Resource) new ClassPathResource("Sample.drl"),
ResourceType.DRL);
        
        System.out.println("Completed createKnowledgeSession!! ");
        if (kbuilder.hasErrors()) {
            if (kbuilder.getErrors().size() > 0) {
                for (KnowledgeBuilderError kerror : kbuilder.getErrors()) {
                    System.err.println(kerror);
                }
            }
        }
        KnowledgeBase kbase = kbuilder.newKnowledgeBase();
        return kbase.newStatefulKnowledgeSession();
        //return kbase.newStatefulKnowledgeSession();
    }
