Log SOAP Messages

I created a class that intercepts the Request-Response cycle of SOAP message exchange and I wanted to log the exchange of messages. What's the best way so that I could log the SOAP message in my log file?

I dont want it to be pretty printed in my log file but I just want to access and view the request and response SOAP envelope.

I tried with this code:

public class LogHandler{    
    private static final Logger _LOG;
    @Override
    protected void handleResponse(SOAPMessage message)
        logSOAPMessage(message);
    }
    @Override
    protected void handleRequest(SOAPMessage message)
        logSOAPMessage(message);
    }    
    private void logSOAPMessage(SOAPMessage message){
      _LOG.info(":: Logging SOAP Message :: " + message.toString());
    }
}

But doesnt get the required message.

:: Logging SOAP Message :: oracle.j2ee.ws.saaj.soap.soap11.Message11@715346

Any hints?
