I've been reading through "Section 7.2.3, Using your new work item in your processes" to see how to pass process variables to a work item. Even though the values of each process variable are getting passed each work item, I'm getting the following XML error in the Eclipse console:
| 1 | 02/05 11:43:16,406[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 40, 62): cvc-id.2: There are multiple occurrences of ID value '_4_Source_IPInput'. |
| 4 | 02/05 11:43:16,409[main] ERROR drools.xml.ExtensibleXmlParser.error - (null: 40, 62): cvc-attribute.3: The value '_4_Source_IPInput' of attribute 'id' on element 'dataInput' is not valid with respect to its type, 'ID'. |

*parameters passed into work item: 111.111.111.111, 2013 05 02 09:00:00, 2013 04 02 09:00:00*
Note the last line in red shows the values are being passed. Does anyone see anything in the folllowing that would cause the Drools XML error?
**********
public class ProcessMain {
public static final void main(String[] args) throws Exception {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
// start a new process instance
Map<String,Object> params = new HashMap<String,Object>();
params.put("processIP", "111.111.111.111");
params.put("processStartDate", "2013 05 02 09:00:00");
params.put("processEndDate", "2013 04 02 09:00:00");
ksession.getWorkItemManager().registerWorkItemHandler("IP Conversations", new IPConversationsWorkItemHandler());
ksession.startProcess("com.sample.bpmn.hello",params);
}
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2);
return kbuilder.newKnowledgeBase();
}
}
***********
The Work Item Handler is:
**********
package com.sample;
import org.drools.runtime.process.WorkItem;
import org.drools.runtime.process.WorkItemHandler;
import org.drools.runtime.process.WorkItemManager;
import java.sql.*;
import java.util.*;
public class IPConversationsWorkItemHandler implements WorkItemHandler {
public void executeWorkItem (WorkItem workItem, WorkItemManager manager) {
// extract parameters
String sourceIP = (String) workItem.getParameter("Source_IP");
String startDate = (String) workItem.getParameter("Start_Date");
String endDate = (String) workItem.getParameter("End_Date");
System.out.println("parameters passed into work item: " + sourceIP + "," + startDate + "," + endDate);
// notify manager that work item has been completed
manager.completeWorkItem(workItem.getId(),null);
}
public void abortWorkItem (WorkItem workItem, WorkItemManager manager) {
// do nothing, not planning to abort operation at this time
}
}
*********
*********
The work item definition file has the following entry:
import org.drools.process.core.datatype.impl.type.StringDataType;
[
[
"name" : "IP Conversations",
"parameters" : [
"Source_IP" : new StringDataType(),
"Start_Date" : new StringDataType(),
"End_Date" : new StringDataType()
],
"results" : [
"Source_IPs" : new StringDataType(),
"Source_Ports" : new StringDataType(),
"Dest_IPs" : new StringDataType(),
"Dest_Ports" : new StringDataType(),
"Recv_Time" : new StringDataType()
],
"displayName" : "IP Conversations"
],
]

Here is my thread safe ProcessPersistenceContextManager if someone needs it.
It needs to be set on the Environment param (env.set(EnvironmentName.PERSISTENCE_CONTEXT_MANAGER, persistenceContextManager);) before you pass it to JPAKnowledgeService.newStatefulKnowledgeSession(kbase,null, env)
-----------------------------------------
public class MyJpaProcessPersistenceContextManager implements
ProcessPersistenceContextManager, PersistenceContextManager {
private EntityManagerFactory emf;
private ThreadLocal<EntityManager> appScopedEntityManager=new ThreadLocal<EntityManager>();
protected ThreadLocal<EntityManager> cmdScopedEntityManager=new ThreadLocal<EntityManager>();
public ProcessPersistenceContext getProcessPersistenceContext() {
return new JpaProcessPersistenceContext(cmdScopedEntityManager.get());
}
public MyJpaProcessPersistenceContextManager(Environment env) {
this.emf = (EntityManagerFactory) env.get(EnvironmentName.ENTITY_MANAGER_FACTORY);
}
public PersistenceContext getApplicationScopedPersistenceContext() {
if (this.appScopedEntityManager.get() == null) {
this.appScopedEntityManager.set(this.emf.createEntityManager());
}
return new JpaPersistenceContext(appScopedEntityManager.get());
}
public PersistenceContext getCommandScopedPersistenceContext() {
return new JpaPersistenceContext(this.cmdScopedEntityManager.get());
}
public void beginCommandScopedEntityManager() {
if (cmdScopedEntityManager.get() == null ||
(this.cmdScopedEntityManager.get() != null && !this.cmdScopedEntityManager.get().isOpen())) {
this.cmdScopedEntityManager.set( this.emf.createEntityManager());
}
cmdScopedEntityManager.get().joinTransaction();
appScopedEntityManager.get().joinTransaction();
}
public void endCommandScopedEntityManager() {
if (this.cmdScopedEntityManager.get()!=null){
this.cmdScopedEntityManager.get().flush();
this.cmdScopedEntityManager.get().close();
}
}
public ThreadLocal<EntityManager> getCmdScopedEntityManager() {
return cmdScopedEntityManager;
}
public ThreadLocal<EntityManager> getAppScopedEntityManager() {
