[rules-users] Working in the GWT console

[ramram8]

Hi Kris
I am new to Drools. I didn't perform a test case from eclipse by using a
knowledge agent to load them from guvnor. Well I have a question after I
build the application on Guvnor should I do something like copythe .pkg to a
specific location or just restart the server and Launch the GWT console.
What I did is the following:

1- I uploaded a jar file of my process into Guvnor below is the sample java
file that i am using:

package com.fp;
import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderError;
import org.drools.builder.KnowledgeBuilderErrors;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.logger.KnowledgeRuntimeLogger;
import org.drools.logger.KnowledgeRuntimeLoggerFactory;
import org.drools.process.instance.impl.demo.SystemOutWorkItemHandler;
import org.drools.process.workitem.wsht.WSHumanTaskHandler;
import org.drools.runtime.StatefulKnowledgeSession;


public class TestDrools
{

	public static final void main(String[] args) 
	{
		try 
		{
			System.out.println("\n\n\n  ======== i am here ");
			
			KnowledgeBase kbase = readKnowledgeBase();
			
//			// create the entity manager factory and register it in the environment
//			EntityManagerFactory emf =
//			    Persistence.createEntityManagerFactory(
"org.drools.persistence.jpa" );
//			Environment env = KnowledgeBaseFactory.newEnvironment();
//			env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
//			env.set( EnvironmentName.TRANSACTION_MANAGER,
//			         TransactionManagerServices.getTransactionManager() );
//
//			// create a new knowledge session that uses JPA to store the runtime
state
//			StatefulKnowledgeSession ksession =
//			    JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env
);

			final StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
			
			// start the transaction
//			UserTransaction ut =
//			  (UserTransaction) new InitialContext().lookup(
"java:comp/UserTransaction" );
//			ut.begin();

			KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
			ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new
WSHumanTaskHandler());
			ksession.getWorkItemManager().registerWorkItemHandler("Log", new
SystemOutWorkItemHandler());
			
			// perform multiple commands inside one transaction
			ksession.startProcess("testDroolsFlow");
			//ksession.fireAllRules();

			// commit the transaction
//			ut.commit();
			
			
			
		} catch (Throwable t) 
		{
			t.printStackTrace();
		}
	}
	
	private static KnowledgeBase readKnowledgeBase() throws Exception 
	{
		KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
		kbuilder.add(ResourceFactory.newClassPathResource("testDroolsFlow.rf"),
ResourceType.DRF);
		KnowledgeBuilderErrors errors = kbuilder.getErrors();
		if (errors.size() > 0) 
		{
			for (KnowledgeBuilderError error: errors) 
			{
				System.err.println(error);
			}
			throw new IllegalArgumentException("Could not parse knowledge.");
		}
		KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
		kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
		return kbase;
	}
	
}

2- uploading the process rule flow below is the .rf file that i am using:

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"

    <connection from="4" to="6" />
  </connections>

</process>

3- building the default package and creating a snapshot.

4- restarting the JBOSS server and launching the console.

Are the steps that i am performing correct or is there something missing??
