Print out the SOAP request

[Jeppe Sommer]

How can I print out the SOAP request to see how the SOAP Envelope looks like?

package soap;
 
import java.util.*;
import java.net.*;
import java.io.*;
import org.apache.soap.*;
import org.apache.soap.encoding.*;
import org.apache.soap.encoding.soapenc.*;
import org.apache.soap.rpc.*;
 
import javax.servlet.*;
import javax.servlet.http.*;
 
public class SOAP extends HttpServlet  {
 
   private static final String URL ="https://myWebSERVICE.asmx";

public void service ( HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
 
    try {
     // Address of SOAP router 
         URL url = new URL( URL );
         
   // buyersReferenceID
         String to= "12312312";
         
   // SellerPartyId
         String from = "22222222";
   
   //Object which create the OIOXML invoice 
   soap.ReadingList obj_read = new soap.ReadingList();
   
   //Get the OIOXML document converted to String
   String OIOXMLDocument = obj_read.convertToString();
   System.out.println( OIOXMLDocument );
   
         // Build the call
         Call call = new Call();
         call.setSOAPMappingRegistry( new SOAPMappingRegistry() );
         call.setEncodingStyleURI( Constants.NS_URI_SOAP_ENC );
         
   //Target URI
   call.setTargetObjectURI("http://test.com/MessageBroker");
   
   //Method name
   call.setMethodName("SubmitDocument");
         Vector params = new Vector();
         
   //Add parameter to
   params.addElement( new Parameter( "to", String.class, to, null ) );
         
   //Add parameter from
     params.addElement( new Parameter("from", String.class, from, null ) );
         
   //Add parameter document
     params.addElement( new Parameter("document", String.class, OIOXMLDocument, null ) );
 
     call.setParams( params );
 
         // Invoke the call to the SOAP server AND SOAP ACTION URI
         Response resp = call.invoke( url, "" );
   
         // Print the returned string
         boolean status = resp.generatedFault();
     System.out.println( status );
         Parameter ret = resp.getReturnValue();
         Object value = ret.getValue();
         System.out.println(value);
 }
 catch ( Exception e ){ 
    
   e.printStackTrace();
 }
   }
}

It would be much less messy to use a tool like TCPMon to visualize the SOAP request and response. That's also part of the Axis download, and the documentation is here.

[Jeppe Sommer]

Is that the only way to use a tool like "tcpmon" to see how the envelop looks like? I hope there was a certain method to print out what is sent to the webservice...

you may use a message handler to print out the soap messages.
by using handlers you can intercept a message before going out or comming in.
for more information look at :

Here's a code snippet I used to print out a SOAP message.

import javax.xml.soap.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamResult;
 
SOAPMessage reply = ...
 
// Create the transformer
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
// Extract the content of the reply
Source sourceContent = reply.getSOAPPart().getContent();
// Set the output for the transformation
StreamResult result = new StreamResult(System.out);
transformer.transform(sourceContent, result);
System.out.println();

When implementing this code snippet in a web service msg handler, where does the println go to?

[Ulf Dittmer]

@Paul:

It uses standard out, so whereever that goes, the output will go. On the server it usually ends up in one of the log files, but that depends on which server is used.
