hi guys,

I am trying to upload my rules from jboss-brms to my eclipse in order to run it against the working memory.
The following is my code and change-set.xml file and I am getting the following error stack.
I have started the jboss-server and it is connected correctly.
But I am not able to figure out the error I am getting and is my change-set and code proper?
The error says that it is unable to parse change-set.xml and unable to connect to the server. I have just specified the url path in my change-set file and the types of files it should be looking out for.
What else do I need to incorporate for it to connect to the server??? I could not find much help in the documentation.

Please help me. I am relatively new to Drools.

Code in my Runner class:

KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
        ResourceFactory.getResourceChangeScannerService().start();
        ResourceFactory.getResourceChangeNotifierService().start();

        // creating a knowledge agent
        KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();

        KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent", kbase,aconf );
        kagent.applyChangeSet( ResourceFactory.newUrlResource("http://localhost:8280/jboss-brms/org.drools.guvnor.Guvnor/Guvnor.html"));
        StatefulKnowledgeSession ksession = kagent.getKnowledgeBase().newStatefulKnowledgeSession();

//     StatelessSession workingMemory = ruleBase.newStatelessSession();
        ArrayList<Ip> ipList = new ArrayList<Ip>();

        ksession.setGlobal("ipList", ipList);
        ksession.insert(al);
        ksession.fireAllRules();
        ksession.dispose();

my change-set.xml file:

<change-set xmlns='http://drools.org/drools-5.0/change-set'
             xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
             xs:schemaLocation='http://drools.org/drools-5.0/change-set.xsd' >

       <resource source='http://localhost:8280/jboss-brms' type='BRL' />
   </add>
</change-set>

error stack:
