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&quo...;
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'
