simple SOAP Request/Response

[Anonymous]

Hi all,
actionR and locationR are form parameters in the same jsp page.
Somehow I always get exception. It is so simple, what might be the problem?
I just want to get the acknowledgement and show success message on the jsp page.

boolean successful = false;
String dateR, actionR, locationR;
dateR = request.getParameter("date");
actionR = request.getParameter("actionR");
locationR = request.getParameter("locationR");
if (dateR==null) dateR="....today"; //using DateFormat...
if (  actionR!=null && !actionR.equals("") && locationR!=null && !locationR.equals("")  ) {
try {
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnectionsoapConnection     = soapConnectionFactory.createConnection();
// Create the request message and give it Content!
MessageFactory messageFactory  = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();
SOAPPart soapPart   = soapMessage.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPHeader header     = envelope.getHeader();
SOAPBody body      = envelope.getBody();
SOAPFactory soapFactory = SOAPFactory.newInstance();
Name bodyName= envelope.createName("myBodyName", "b", "http://somewhere.org/WS/");
SOAPBodyElement bodyElement= body.addBodyElement(bodyName);

Name name = envelope.createName("locationCode");
SOAPElement locationCode = bodyElement.addChildElement(name);
locationCode.addTextNode(locationR);
name = envelope.createName("type");
SOAPElement type = bodyElement.addChildElement(name);
type.addTextNode(actionR);
name = envelope.createName("date");
SOAPElement date = bodyElement.addChildElement(name);
date.addTextNode(dateR);
java.net.URL endpoint = new URL(".....");
javax.xml.soap.SOAPMessage responseSOAPMessage = soapConnection.call((javax.xml.soap.SOAPMessage)soapMessage, endpoint);
soapConnection.close();

SOAPPart sp = responseSOAPMessage.getSOAPPart();
SOAPEnvelope se = sp.getEnvelope();
SOAPBody sb = se.getBody();
java.util.Iterator it = sb.getChildElements(bodyName);
SOAPBodyElement bodyElementResponse= (SOAPBodyElement) it.next();
if (bodyElementResponse!=null) {
successful = true;
out.println("SUCCESSFULLY TRANSMITTED!!!");
}
    } 
    catch (Exception ex) {
    ex.printStackTrace();
    }
}

Well!.. whats the error message ?

sth like:

Message: Server caught unhandled exception from servlet [jsp]: Server caught unhandled exception from servlet [jsp]: SOAPEnvelope
Target Servlet: jsp
StackTrace: 
Root Error-1: SOAPEnvelope
java.lang.Exception: SOAPEnvelope
java.lang.Throwable(java.lang.String)
java.lang.Exception(java.lang.String)

Do You know what line it is failing on? That would be helpful. If it is failing in the try catch you listed, the printstacktrace should show what line you failed at.

Error 500 is of no help...

Error 500
An error has occured while processing request:http://localhost:8000/xxxxx.jsp
Message: Server caught unhandled exception from servlet [jsp]: org.apache.commons.discovery.tools.DiscoverSingleton  

Actually I re-debugged it. It is a Throwable, not an Exception!
