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:

</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??
