Webservice SOAP Message Monitoring or Logging
Can someone tell me how to capture SOAP messages passed between client and server webservice applications.
I have tried using both tools. pocket soap http://www.pocketsoap.com/pocketsoap/
Violinist http://www.fiddlertool.com/fiddler/
I may be missing some settings, it doesn't work for me.
help would be more appreciated.

if you're curious, you can write a handler in Java that extends the GenericSOAPHandler class and prints the output wherever you like. In this (simple) case, the server log is:
@SuppressWarnings("rawtypes")
public class MyHandler extends GenericSOAPHandler {
private void print(InputStream input, OutputStream out) throws Exception {
try {
DocumentBuilder parser;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
parser = factory.newDocumentBuilder();
Document document = parser.parse(input);
Transformer serializer = TransformerFactory.newInstance().newTransformer();
serializer.setOutputProperty(OutputKeys.INDENT, "yes");
serializer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
serializer.transform(new DOMSource(document), new StreamResult(out));
} catch (TransformerException e) {
// A fatal error occurred
throw new Exception(e);
}
}
@Override
protected boolean handleInbound(MessageContext msgContext) {
SOAPMessageContext soapMessageCtx = (SOAPMessageContext) msgContext;
SOAPMessage soapMessage = soapMessageCtx.getMessage();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
try {
soapMessage.writeTo(outputStream);
byte[] array = outputStream.toByteArray();
ByteArrayInputStream inputStream = new ByteArrayInputStream(array);
System.out.println("SOAP request message:\n");
print(inputStream, System.out);
} catch (SOAPException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return true;
}
@Override
protected boolean handleOutbound(MessageContext msgContext) {
SOAPMessageContext soapMessageCtx = (SOAPMessageContext) msgContext;
SOAPMessage soapMessage = soapMessageCtx.getMessage();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
try {
soapMessage.writeTo(outputStream);
byte[] array = outputStream.toByteArray();
ByteArrayInputStream inputStream = new ByteArrayInputStream(array);
System.out.println("SOAP response message:\n");
print(inputStream, System.out);
} catch (SOAPException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return true;
}
}
You also need to make sure your handler is included in the jaxws-handlers-server.xml of your server implementation:
<handler-chains xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee javaee_web_services_1_2.xsd">
<handler-chain>
<protocol-bindings>##SOAP11_HTTP</protocol-bindings>
<handler>
<handler-name>DebugHandler</handler-name>
<handler-class>handlers.MyHandler</handler-class>
</handler>
</handler-chain>
</handler-chains>

Here's my code in C ++ to fetch the xml message using Soap Toolkit 3.0 before submitting.
.
.
.
Serializer->EndEnvelope();
/* ___________________ */
char * bufferxml = NULL;
_variant_t punt = _variant_t((IUnknown*)Serializer);
punt.lVal += 48;
_variant_t punt1 = *punt.ppunkVal;
punt1.lVal += 32;
_variant_t punt2 = *punt1.ppunkVal;
punt2.lVal += 4;
memcpy(&bufferxml, (char *) *punt2.ppunkVal, sizeof(char *));
punt2.lVal += 4;
int lengxml = *(punt2.pintVal);
bufferxml[lengxml] = '\0';
/* ___________________ */
// Send the message to the web service
Connector->EndMessage();
.
.
.
punt.Detach();
punt1.Detach();
punt2.Detach();
punt.Clear();
punt1.Clear();
punt2.Clear();
Serializer.Release();
.
.
.
Hope it really helps you, this is my design and it worked for me.
