Hi I am having the following problem:
I am able to start the web cosole successfully and see all the process List
that I want to execute.
My scenario is the following: User Task1 -> User Task2 -> Send Mail
What I did is:
1- upload the jar file into Guvnor
2- upload the rf file into Guvnor
3- Build the package and restart the server
4- After logining into GWT console I can run the process and see in the User
Task1 and I can complete the task with no errors but the problem is that I
am not being able to reach to USER TASK2
any suggestions??
is there problem in the upload in the Guvnor??
is there anything additional that I can do??
Please if anyone have any suggestions on this topic???

Does your test case work if you run it from Eclipse directly (for
example using a knowledge agent to load them from guvnor or simply
loading from file system) and using the Eclipse task client (to
eliminate the possibility that there is something wrong with the
process)? Might be useful if you could show us the process itself as well.

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:

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??

Kris I also found the following issue if the USER TASK 1 and USER TASK 2 are
assigned to the same user I can see both tasks and execute them but if for
example Task 1 is assigned to admin and Task 2 is assigned to admin1 after
logging out and logging in as admin1 I cant see that the tasks that are
assigned to him in order to complete the process. Another issue if I have
another scenario a User Task Followed by LOG for example The User task is
executed but the process that is following it which is a LOG in our example
is never reached or executed.
PS. for the LOG process I defined a special handler for it which only
contanins System,out,
public class MyLogHandlerCall implements WorkItemHandler
{
public void executeWorkItem(WorkItem workItem, WorkItemManager manager)
{
try
{
System.out.println("RAAAAMMMM TEST");
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void abortWorkItem(WorkItem workItem, WorkItemManager manager)
{
System.out.println((new StringBuilder()).append("Aborting work item
").append(workItem).toString());
manager.abortWorkItem(workItem.getId());
}
}
Please advise!!!!!
