[Fix] SOAP Message Factory response error

I am writing both the server and the client. The server builds the XML using JAXB marshalling and piping back to the client in the HTTP socket. From the client the request is built using the message factory and sent over the connection factory instantiation. When the response is received the SAAJ API indicates the response was bad and equals null. The client is a applet.

Error Message
Jun 29, 2008 5:01:49 PM com.sun.xml.internal.messaging.saaj.client.p2p.HttpSOAPConnection post
SEVERE: SAAJ0008: Bad Response; null
com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: java.security.PrivilegedActionException: com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Bad response: (-1null

Client Code

Code

GeSHi (java):
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
if(connection == null)
	connection = soapConnectionFactory.createConnection();
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();
SOAPHeader header = message.getSOAPHeader();
SOAPBody body = message.getSOAPBody();
header.detachNode();
QName bodymain = new QName("icb_xml");
SOAPBodyElement mainbodyElement =  body.addBodyElement(bodymain);
...
...
...
 URL endpoint = new URL(serverurl);
System.out.println("b");
SOAPMessage response = connection.call(message, endpoint);
