I modified XMLRPC for transport with Apache HttpClient. This
modification can solve all your problems, I think. I didn't share this
modification with others because I didn't test it (and I don't know
how to make diff :) yet thouroghly.

I did it, because used URLConection has some problems and has no
funcionality I need (aborting connection).

some code snippets to help you patch the lib (you need to modify some
other constructors - I deleted them, I'm not going to use them):

your program
---------------------------------------

HttpClient client = new HttpClient();
client.setConnectionTimeout(1000);
PostMethod method = new PostMethod("http://example....");
XmlRpcClient xmlrpc = new XmlRpcClient(client, method);
Vector result = (Vector) xmlrpc.execute("getShowColumns", params);

XmlRpcClient
---------------------------------------

private HttpClient client;
private PostMethod postmethod;
....

public XmlRpcClient(HttpClient client, PostMethod method)
    {
        this.postmethod = method;
    this.client = client;
.....
public Object execute(String method, Vector params)
            throws XmlRpcException, IOException
    {
        Worker worker = getWorker(false);
        try
        {
            Object retval = worker.execute(method, params);
...
Object execute(String method, Vector params)
                throws XmlRpcException, IOException
        {
.....
byte[] request = buffer.toByteArray();

                //URLConnection con = url.openConnection();
                //con.setDoInput(true);
                //con.setDoOutput(true);
                //con.setUseCaches(false);
                //con.setAllowUserInteraction(false);

            postmethod.setRequestHeader("Content-Length",
Integer.toString(request.length));
            postmethod.setRequestHeader("Content-type", "text/xml;
charset=UTF-8");

                if (auth != null)
                {
                    postmethod.setRequestHeader("Authorization",
"Basic " + auth);
                }
            postmethod.setRequestBody(buffer.toString());
            try {
int statusCode = client.executeMethod(postmethod);
if (statusCode == HttpStatus.SC_OK) {
InputStream in = postmethod.getResponseBodyAsStream();
parse(in);
} else {
System.out.println("fetch error");
}
            } catch (IOException ioe) {
            System.out.println(ioe);
            } finally {
            postmethod.releaseConnection();
            }
            }


Hope these changes are ok and it'll help you. I'm using it in
prototype of my program and it works great...

If anyone from XMLRPC lib developers can check this and say if it's
smart enough to get into main tree, or it's stupid change, I will be
glad.
