Java APIs

I have written the following code to connect content engine and process engine..

MY content engine is connected fine and good...But process engine is not connecting

code:

public String PE_CONNECTION_POINT = "PEConnection";
public Connection ceConnection;
public Domain ceDomain;

public void testFileNetConnection()
{

/*
* Connect to Content Engine and retrieve a list of
* properties for the base 'Document' document class
*/
ceConnection =
Factory.Connection.getConnection(FILENET_URI);

Subject ceSubject =
UserContext.createSubject(ceConnection, FILENET_USERNAME, FILENET_PASSWORD, null);

UserContext.get().pushSubject(ceSubject);

ceDomain = Factory.Domain.fetchInstance(ceConnection, CE_DOMAIN, null);

ObjectStore ceObjectStore = Factory.ObjectStore.fetchInstance(ceDomain, CE_OBJECTSTORE, null);

ClassDefinition classDef =
Factory.ClassDefinition.fetchInstance(ceObjectStore, "pawan", null);

PropertyDefinitionList properties = classDef.get_PropertyDefinitions();

for (Iterator propertyIter = properties.iterator(); propertyIter.hasNext();) {
PropertyDefinition property = (PropertyDefinition) propertyIter.next();

System.out.println("Property: " + property.get_DisplayName());
}

//this.instantiateFolder(ceObjectStore);
//this.createFile(ceObjectStore, ceDomain);
UserContext.get().popSubject();

/*
* Connect to Process Engine and retrieve a list of
* Queues for this Connection Point
*/
VWSession peSession = new VWSession();
peSession.setBootstrapCEURI(FILENET_URI);
String[] queueNames = null;
try
{
peSession.logon(FILENET_USERNAME ,FILENET_PASSWORD,PE_CONNECTION_POINT);

queueNames =
peSession.fetchQueueNames(VWSession.QUEUE_PROCESS);
}
catch(Exception es){es.printStackTrace();}

for (String queue : queueNames)
{
System.out.println("Queue: " + queue);
}

}
The output of above code I have attached part of successful connection of the content engine and the error of process engine

When to remove the above error I add IBMORB.jar in enviroment variable then I get following error

log4j:WARN The log4j system is not properly configured!
log4j:WARN All ERROR messages will be sent to the system console until proper configuration has been detected.
