Hi,

I am new to drools.

I am using drools 6.5.0 and wildfly 10.

My drools rules are executed in eclipse perfectly.

I am developing a REST application with drools rules and executing through REST url.

My REST application is deployed successfully on wildfly.

But, If I call the url, it throws the below exception in wildfly console.

Is it mandatory to deploy KIE server for the rule execution?  Because in tomcat the same application is working fine without KIE server.

I have the following code :

droolsTest.java

    KieServices ks = KieServices.Factory.get();  // working fine

    KieContainer kContainer = ks.getKieClasspathContainer();  // Error thrown in this statement

    KieSession kSession = kContainer.newKieSession("ksession-rules");

    Message message = new Message();

    message.setMessage("Hello World Testing");

    message.setStatus(Message.HELLO);

    kSession.insert(message);

    kSession.fireAllRules();

    System.out.println("Drools Rules execution is Completed");

Could any one provide your help.
