Hi I am using Drool-5.2.0 final, Guvnor 5.2.0 final and designer-2.0-jboss.war in Drools-Guvnor. In Designer, I created simple process with start node, one task node, and end node. I made Task type of task node as "Script". I entered simple java code as System.out.print("Hi "); in the Script option of the task node. Sorry I dont know API's used for loading this process in Eclipse. So can any one tell me the API's used for loading this process in Eclipse.? I tried alot, but i am getting exceptions as: java.lang.NullPointerException at org.drools.common.AbstractWorkingMemory.startProcess(AbstractWorkingMemory.java:1090) at org.drools.impl.StatefulKnowledgeSessionImpl.startProcess(StatefulKnowledgeSessionImpl.java:301) at com.simple.Mainclass.main(Mainclass.java:30) I am also sending my code: package com.simple; import org.drools.KnowledgeBase; import org.drools.agent.KnowledgeAgent; import org.drools.agent.KnowledgeAgentFactory; import org.drools.io.Resource; import org.drools.io.ResourceFactory; import org.drools.rule.FactType; import org.drools.runtime.StatefulKnowledgeSession; public class Mainclass { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub try { KnowledgeBase kbase=readBase(); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); ksession.startProcess("sayhi"); //ID of the process which is created in Designer // ksession.fireAllRules(); ksession.dispose(); } catch(Throwable t) { t.printStackTrace(); } } private static KnowledgeBase readBase() { KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("AccountAgent"); Resource changeset = ResourceFactory.newClassPathResource("com/simple/ProcessChangeSet.xml"); kagent.applyChangeSet(changeset); KnowledgeBase kbase = kagent.getKnowledgeBase(); return kbase; } } Please guide me in proper way. Thanks in advance.
