org.drools.RuntimeDroolsException: invalid package name

I am a new bie to JBPM.

I have created bpmn file with a start ,diverge and two scripts and a converge and endtask.

MY code is

package com.sample;

import java.util.HashMap;
import java.util.Map;

import org.drools.KnowledgeBase;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.runtime.StatefulKnowledgeSession;
import org.drools.runtime.process.ProcessInstance;


 public class ProcessTest {

public static void main(String[] args){

    KnowledgeBuilder kbuilder =      KnowledgeBuilderFactory.newKnowledgeBuilder();

    kbuilder.add( ResourceFactory.newClassPathResource("sample.bpmn"),

                  ResourceType.BPMN2 );
    KnowledgeBase kbase = kbuilder.newKnowledgeBase();

    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

    Map<String,Object> params=new HashMap<String,Object>();

    params.put("income", 1200);


    ProcessInstance processInstance = ksession.startProcess("com.sample.bpmn.hello",params);
}

}

But i am getting the following error 

org.drools.RuntimeDroolsException: invalid package name

I have given package name com.sample in sample.bpmn

My sample.bpmn file is

sample.bpmn

Found the solution for this issue. This is related to config change in the Diverge gateway Constraints. For each constraint, try using **Type: code and Dialect: java. Also do not forget to put semicolon ; at the end of the statement in the Textual editor of each constraint. Best way to check this is to open the RF file in a text editor and validate the content.

Something like:

<constraints>
  <constraint toNodeId="3" toType="DROOLS_DEFAULT" name="Flight" priority="1" type="code" dialect="java" >return income &gt; 1000;</constraint>
  <constraint toNodeId="4" toType="DROOLS_DEFAULT" name="Train" priority="1" type="code" dialect="java" >return income &lt; 1000;</constraint>
</constraints>

Hope this will help.
