Com.evermind.server.rmi.OrionRemoteException

Question

Hi I have a simple AXIS2 webservice and BPEL process deployed on the same box but on two seperate OC4J's.
I then have a remote junit test which I invoke from a remote client and it works fine.
I then take this test case into JunitPerf and create a simple load test.
Bearing in mind the services are simple and only return a boolean.
The load test works fine for five users, but when I try any more than 5, say 10 for instance I get this exception,
com.evermind.server.rmi.OrionRemoteException: Disconnected: Unknown command: 100

Mt test case effetcively looks like this,
package test.bpel;
import java.util.Hashtable;
import java.util.Map;
import javax.naming.Context;
import junit.framework.TestCase;
import org.w3c.dom.Element;
import com.collaxa.xml.XMLHelper;
import com.oracle.bpel.client.Locator;
import com.oracle.bpel.client.NormalizedMessage;
import com.oracle.bpel.client.delivery.IDeliveryService;
public class TestFileCreateFromTemplate extends TestCase {
     private StringBuffer xml = new StringBuffer();
     public TestFileCreateFromTemplate(String name){
          super(name);
     public void testProcessFileCreateFromTemplate(){
          xml.append("<ns1:FileCreateFromTemplateReq xmlns:ns1=\"http://www.thalesgroup.com/arrcc2is/GENB/FileCreateFromTemplate\">");
          xml.append("<ns1:templateNameLocation>Test</ns1:templateNameLocation>");
          xml.append("<ns1:newFileName>Test</ns1:newFileName>");
          xml.append("<ns1:newFileLocation>Test</ns1:newFileLocation>");
          xml.append("<ns1:destinationFolder>Test</ns1:destinationFolder>");
          xml.append("<ns1:securityClassification>Test</ns1:securityClassification>");
          xml.append("<ns1:dateOfCreation>12/2/2007</ns1:dateOfCreation>");
          xml.append("<ns1:viewFileOnCreation>true</ns1:viewFileOnCreation>");
          xml.append("<ns1:arrayOfMetadata xmlns:ns2=\"http://uk.thalesgroup.com/arrcc2is/geni/geni_common/geni_types\">");
          xml.append("<ns2:metadataField>");
          xml.append("<ns2:name>Test</ns2:name>");
          xml.append("<ns2:valueAsString>Test</ns2:valueAsString>");
          xml.append("<ns2:valueAsInteger>1</ns2:valueAsInteger>");
          xml.append("<ns2:valueAsLong>1</ns2:valueAsLong>");
          xml.append("<ns2:valueAsDouble>1</ns2:valueAsDouble>");
          xml.append("<ns2:valueAsBoolean>true</ns2:valueAsBoolean>");
          xml.append("</ns2:metadataField>");
          xml.append("</ns1:arrayOfMetadata>");
          xml.append("</ns1:FileCreateFromTemplateReq>");
          try {
               String jndiFactory = "com.evermind.server.rmi.RMIInitialContextFactory";
               String jndiUsername = "oc4jadmin";
               String jndiPassword = "babylon5";
               String jndiProviderUrl = "opmn:ormi://wells175732.int.rdel.co.uk:6004:OC4J_SOA/orabpel";
               Hashtable jndi = new Hashtable();
               jndi.put(Context.PROVIDER_URL, jndiProviderUrl);
               jndi.put(Context.INITIAL_CONTEXT_FACTORY, jndiFactory);
               jndi.put(Context.SECURITY_PRINCIPAL, jndiUsername);
               jndi.put(Context.SECURITY_CREDENTIALS, jndiPassword);
               Locator locator = new Locator("default","bpel",jndi);
               IDeliveryService deliveryService =
                         (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
               NormalizedMessage nm = new NormalizedMessage( );
               nm.addPart("payload", xml.toString() );
               System.out.println("Making Request: ");
               NormalizedMessage res = deliveryService.request("FileCreateFromTemplate", "process", nm);
               Map payload = res.getPayload();
               System.out.println("Got Request: ");
               Element element = (Element)payload.get("payload");
               System.out.println("RESPONSE XML: ");
               System.out.println( XMLHelper.toXML(element) );
          } catch(Exception e) {
               e.printStackTrace();
               fail("TEST FAILED BECAUSE : " + e.getMessage());
The load test class is a follows, very basic,
package test.bpel;
import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
import com.clarkware.junitperf.LoadTest;
import com.clarkware.junitperf.TestFactory;
public class ARRCLoadTest extends TestCase{
     private static final int users = 10;
     private static final int iterations = 1;
     public ARRCLoadTest(){}
     public static Test suite(){
          TestSuite suite = new TestSuite();
          suite.addTest(testUnderLoad());
          return suite;
     public static Test testUnderLoad(){
          Test factory = new TestFactory(TestFileCreateFromTemplate.class);
          Test loadTest = new LoadTest(factory, users, iterations);
          return loadTest;
Any ideas why this would be happening. I was thinking is there a maximum of concurrent users somewhere to be set in the enterprise manager.
I also checked my BPEL Console instances for this specific bpel process and they have been created for all 10 processes.

Kumar,
From the stack trace you have posted, it appears that in line 87 of file "ResourceMgrEJB.java" (in package "com.dsr.sov02.resourcemgr.sf"), you are invoking a non-existent method. Have you looked at that line of the code?
Good Luck,
Avi.
