Always get "unknown method" with PHP server

[Alexander Langer]

Hi there!   I'm about to implement some communication between a PHP XML-RPC server and a Java client. The server is doing fine, a PHP client is working perfectly, but I just can't get a Java client to work. Every time I get a "Error: Unknown method".   I'm now at a point where I try to connect to a PHP server sample script, which looks like this: <?php require_once("XML/RPC/Server.php"); function sumAndDifference($params) { $xval = $params->getParam(0); $x = $xval->scalarval(); $yval = $params->getParam(1); $y = $yval->scalaraval(); $struct = array('sum' => new XML_RPC_Value($x + $y, 'int'), 'difference' => new XML_RPC_Value($x - $y, 'int')); return new XML_RPC_Response(new XML_RPC_Value($struct, 'struct')); } $sumAndDifference_sig = array(array('struct', 'int', 'int')); $sumAndDifference_doc = 'Add and subtract two numbers'; new XML_RPC_Server(array('sample.sumAndDifference' => array('function' => 'sumAndDifference', 'signature' => $sumAndDifference_sig, 'docstring' => $sumAndDifference_doc))); ?> After that I tried to connect for debug purposes, but I only got this:   C:\work\pfc\dev\Process_Viewer\classes>java org.apache.xmlrpc.XmlRpcClient http://localhost/pfl/server-test.php sample.sumAndDifference 1 3 Error: Unknown method   Has anyone an idea of what I may be doing wrong? I'm using current versions of the java library as well as the PEAR PHP module...   Thanks, al
