[rules-users] Dynamic Loading of Rules from BRMS

[jillika iyer]

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 ( which is a java error but just attaching it for
giving more info).

I have started the jboss-server and it is connected correctly.

I am getting a java based error which says that it is unable to parse
change-set.xml and unable to connect to the server.

I just want to know if I am not the right path for creating the required
change-set.xml file due to which I am getting the java connection error.

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???

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'
>
   <add>
   <!-- Add for specifying URLs-->
       <resource source='http://localhost:8280/jboss-brms' type='DRL' />
       <resource source='http://localhost:8280/jboss-brms' type='DSLR' />
       <resource source='http://localhost:8280/jboss-brmss/sample-dsl.dsl'
type='DSL' />";
       <resource source='http://localhost:8280/jboss-brms' type='BRL' />
   </add>
 </change-set>
