Here is the methods I wrote to marshal SOAPMessages. This would provide
output similar to what you see in TCPMon.
I have modified it to take any object and add it as <element
...>..</element> in the SOAP.
/**
* @param object passed to create SOAPMessage
*/
public static String marshal(Object msg)
{
if (msg == null)
return null;
RPCElement rpcElement = new RPCElement("soapmessage");
// Structure of a SOAP Envelope is
// SOAPEnvelope
// --> RPCElement
// --->
RPCParam * n
// Create RPCParam of each ISMessage param.
// Serialize. Encapuslate it with RPCElement
// that contains the dummy method name. Set
// RPCElement as body in SOAPEnvelope
String paramName = "param"
Class cl = param.getClass();
Object value = param;
QName xmlTypeQName = getTypeQName(cl); //
AxisEngine provides implementation of this. I have not shown it here. If
you need it email me.
ParameterDesc paramDesc = new ParameterDesc();
paramDesc.setQName(new QName("", paramName));
paramDesc.setTypeQName(xmlTypeQName);
paramDesc.setJavaType(cl);
RPCParam rpcParam = new RPCParam(paramName,
value);
rpcParam.setParamDesc(paramDesc);
rpcElement.addParam(rpcParam);
SOAPEnvelope message = new SOAPEnvelope();
message.addBodyElement(rpcElement);
StringBuffer sb = new StringBuffer();
String retStr = null;
try
{
// This is Axis Specific code to serialize
SOAPEnvelope
// MessageContext is used through out AxisEngine
which
// is used as scratchpad by different modules of
Axis.
// Hence it is important tha twe set the
SOAPEnvelope in
// message context
MessageContext mc = new
MessageContext(aa.getAxisEngine());
Message soapMsg = new Message(message);
mc.setMessage(soapMsg);
// We need to add content type header as it is
used during
// deserialization to unmarshal any attachements
present.
// Content header will specify the multipart
mime header contents
// along with boundry tags.
sb.append(HTTPConstants.HEADER_CONTENT_TYPE).append(": ");
long contentLength = soapMsg.getContentLength();
if (log.isDebugEnabled())
log.debug(" ContentLength " +
contentLength);
// This Call does all the magic of analyzing
soap message and
// any attachements to form the header
String contentType =
soapMsg.getContentType(mc.getSOAPConstants());
sb.append(contentType);
sb.append("\r\n"); // Required CR for Content
Header
ByteArrayOutputStream bos = new
ByteArrayOutputStream();
soapMsg.writeTo(bos); // Serialize the actual
soap message along with attachments
sb.append(bos.toString());
retStr = sb.toString(); // Combine content
header with body and we are done
if (log.isDebugEnabled())
log.debug(" Marshalled Msg is \n" +
retStr);
}
catch (Exception e)
{
log.error(" Exception occured while dumping
ISMessage ", e);
}
return retStr;
}

Why don't you trace the soap message on TCP level using a tool like
ngrep or ethereal?
