[PEAR::SOAP] How to determine which functions are available to a Client

Hello! I found PEAR-SOAP and it's great, but due to the absence of documentation I did not find out how to confine the available methods of my server class. You can found an example at: http://nopaste.php.cd/25773 Unfortunately the dispatch map seems not to be used by the SOAP_Server class. With my current configuration in the server class file my client can call every method. This should not be. How can I set the methods which are available for a SOAP client and which are not. Another question: How can I set an alias name for a method? This means: My SOAP client calls the method foo and the server maps it (because I made somewhere an entry for that) to my real method bar. Do I have to use WSDL for that? It would be nice if you give me a short example how to solve the described problems. Thanks in advance, herojoker
