These are almost always a result of having display_errors on on the
server. Make sure the script where you server the XML-RPC server has
display_errors turned off.

So far, so good -- you've defined the php docblock correctly, which is
the other typical pitfall for the various server classes.

You should never return anything other than the XML-RPC response; doing
otherwise will result in invalid XML, which means the client will not be
able to parse it.

On the server side, try logging the request and response to a file to
see first what you're receiving (you want to be sure the XML received is
valid) and what you're returning (you need to know if you're always
returning a fault exception, or if the XML is indeed valid). Easy way to
do that:
$response = $server->handle();
$request = $server->getRequest();
$log = new Zend_Log(new Zend_Log_Writer_Stream('/tmp/xmlrpc.log'));
$log->info("Request:\n$request");
$log->info("Response:\n$response");
echo $response;
If you see that you're always getting a fault response, you should check
your application code (i.e., the class(es) you've attached to the
server) to see if there are any exceptions being thrown -- perhaps in
the constructor. Finally, it's entirely possible that the application
class isn't being loaded in the first place, which would lead to *no*
response whatsoever; make sure your class is being loaded either via
__autoload or a require_once call.
Hopefully with that information, you should be able to debug a bit
further.
