Greetings,

I have created and deployed two web applications(say webapp1, webapp2) that generates SOAP message to access a remote web service. We are using Jboss 5.0.0.GA.
Both these applications run fine, if I run then individually. That is, when I start the jboss server and access webapp1 first. Then, I do not have any trouble with webapp1. Now, when I access webapp2, I get the error message listed below.

I get the same error message, when I start the jboss server and access webapp2 for the first and try to access webapp1 second.

So, if I am testing webapp1 and want to test webapp2, I have to restart the jboss server and access webapp2 as soon as the server starts up.

This is the code I have in webapp1
******************* Code on webapp1 ***************

 QName serviceQName = new QName(namespace, serviceName);
 Service service = Service.create(serviceQName);
 QName portQName = new QName(namespace, portName);
 service.addPort(portQName, SOAPBinding.SOAP11HTTP_BINDING,
 endpointAddress);
 Dispatch<SOAPMessage> dispatch = service.createDispatch(portQName,
 SOAPMessage.class, Service.Mode.MESSAGE);

 final String operationName = props.getProperty(svc
 + ".operationName");
 MessageFactory factory = MessageFactory.newInstance();
 SOAPMessage soapRequest = factory.createMessage();
 soapRequest.setProperty("WRITE_XML_DECLARATION ", false);
 SOAPBody body = soapRequest.getSOAPBody();
 QName payloadName = new QName(namespace, operationName, "ns1");
 SOAPBodyElement payload = body.addBodyElement(payloadName);
 SOAPElement message = payload.addChildElement("arg0");
 message.addTextNode(userName);
 message = payload.addChildElement("arg1");
 message.addTextNode("");
 soapRequest.writeTo(System.out);
 SOAPMessage soapResponse = null;
 soapResponse = dispatch.invoke(soapRequest);
 soapResponse.writeTo(System.out);

This is the code I have in webapp2

 //First create the connection
 SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
 connection = soapConnFactory.createConnection();
 //Next, create the actual message
 MessageFactory messageFactory = MessageFactory.newInstance();
 SOAPMessage message = messageFactory.createMessage();
 //Create objects for the message parts
 SOAPPart soapPart = message.getSOAPPart();
 SOAPEnvelope envelope = soapPart.getEnvelope();
 SOAPBody body = envelope.getBody();
 //Populate the body
 //Create the main element and namespace
 SOAPElement bodyElement = body.addChildElement(envelope.createName(operationName,"ns0",namespace));
 //Add content bodyElement.addChildElement("parameter").addTextNode(param);
 //Save the message
 message.saveChanges();
 message.writeTo(System.out);
 //Set the destination
 URL destination = new URL(wsdlURL);
 //Send the message and get a reply
 SOAPMessage reply = connection.call(message, destination);
 System.out.println("\nRESPONSE:\n");
 reply.writeTo(System.out);
