how to get the xml bytes

[Lucio Crusca]

Hello *,

I'm coding some XMLRPC client tests for certain XMLRPC webservices. The server 
is Django and it's being written by someone else, but that's only to say I 
have no control over that code. All I have to do is to write client Java tests 
for the documented services.

Now one of my tests fails. The developer who writes server code asked me to 
add to my failed test output the xml string sent by my client to his server. 
Here is my current java code:

    XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
    config.setServerURL(new URL(url));
    config.setBasicUserName("admin");
    config.setBasicPassword("admin");

    XmlRpcClient client = new XmlRpcClient();
    client.setConfig(config);

    String rpcmethod = "resources.myrpcservice";
    params = new Object[]{1};
    client.execute(rpcmethod, params);

(basically cut & pasted from the examples). How do I intercept the xml string 
my client sends to the server?

Thanks in advance,
Lucio.
