Re: PEAR XML-RPC incompatible with Apache Java xmlrpc?

Hi Justin, thanks for your reply. I couldn't figure out where the problem was, but it must be something low-level. I caught the XML response of PHP via output-buffering to a logfile, and it is perfectly valid. Simply printing this message out in PHP does work, Java recognizes it. I believe PEAR XML-RPC sends some headers or strange characters that the Java SAX parser stumbles upon. The exception says the error is in line 1, column1 of the XML stream. Maybe a unnecessary newline? A UTF-8 BOM? A HTTP problem? I really was unable to find the error, and I'm tired of trying to figure it out. Now I use the Incutio library, which does everything I want it to do. Works flawlessly. I would appreciate it if Greg Beaver's attempt at a new PEAR XML-RPC library was accepted, it sounds really great. Not too shabby what that guy can do in "a fit of boredom" in 2 nights... Regards, Michael

Hi Michael, I'm the guy who did the fix for the "method not found" bug in the PEAR XMLRPC that you added to. (I couldn't believe the lucky accident that still allowed the code to work with that bug!!!) Thought I'd let you know that I was working with Apache XMLRPC vs PHP as client/server and server/client when I came across the above bug, though when I'd fixed it, all worked fine... What's the structure of the XML RPC Response that PHP is returning? (you're right about PHP needing a new RPC library... the PEAR one is getting old shall we say) See following message that appeared here a few days ago.

Line counts:

Client:             147
Server:             270

base xml-rpc class: 64

php driver:         320

xmlrpc-epi driver: 68

interface:          9

TOTAL:              878

TOTAL AT ANY TIME: 560-810 These are prior to commenting. Basic usage is as follows: <?php require_once 'XML/RPC5/Client.php'; $client = new XML_RPC5_Client('http://pear.chiaraquartet.net/xmlrpc.php'); print_r($client->{'system.listMethods'}()); ?> Note that the above syntax allows "." in a method name, as in $obj->{"methodname"}([params]); A call method is available for those who are made queasy by this syntax $client->call('system.listMethods'[, $param1, $param2, ...]); You can also extend the class in two ways to automatically define the class, and call methods normally Option #1: <?php require_once 'XML/RPC5/Client.php'; class myclass extends XML_RPC5_Client {

     protected $rpcclass = 'system';

} $client = new myclass; print_r($client->listMethods()); ?> Option #2: <?php require_once 'XML/RPC5/Client.php'; class XML_RPC5_Client_system extends XML_RPC5_Client {} $client = new XML_RPC5_Client_system; print_r($client->listMethods()); ?> The server is also easy to use, and supports full introspection. Unlike other generic server implementations, it easily supports multiple classes implementing different XML-RPC classes (one class for all "package.*" methods, one class for all "channel.*"). The best feature is that it automatically pulls introspection data from the class using reflection, and so server setup is something like the following: Option #1 (inheritance): <?php require_once 'XML/RPC5/Server.php'; class MyServer extends XML_RPC5_Server {

     /**
      * method summary - will be retrievable by introspection
      * @param string This comment is ignored by docblock parser
      * @param int
      * @return array
      */
     function someFunc($a, $b = 1)
     {

//.....

     }

     /**
      * does something else
      * @param array
      * @return mixed
      */
     function somethingElse($arr)
     {
     }

} $server = new MyServer('xmlrpc.php', 'rpcclass'); // handles rpcclass.someFunc, rpcclass.somethingElse MyServer::run(); ?> Let's say you have a pre-existing class that extends another class, and so you can't make it extend XML_RPC5_Server. No problem! Just use the interface provided, and it will work. Option #2 (interface): <?php require_once 'XML/RPC5/Server.php'; class MyServer extends XML_RPC5_Server implements XML_RPC5_Interface_Server {

     private $_uri;

     public function __construct($uri)
     {
         $this->_uri = $uri;
     }

     /**
      * method summary - will be retrievable by introspection
      * @param string This comment is ignored by docblock parser
      * @param int
      * @return array
      */
     function someFunc($a, $b = 1)
     {

//.....

     }

     /**
      * does something else
      * @param array
      * @return mixed
      */
     function somethingElse($arr)
     {
     }

     public function getXmlrpcServerMethodMap()
     {
         // map rpc method names to real methods
         return array();
     }

     public function getXmlrpcServerUri()
     {
         return $this->_uri;
     }

     public function getXmlrpcServerClassName()
     {
         return 'rpcclass';
     }

     public function getSignatures($rpcclass, $phpclass)
     {
         return XML_RPC5_Server::getSignatures('rpcclass', $this);
     }

} $server = new MyServer('http://pear.chiaraquartet.net/xmlrpc.php'); XML_RPC5_Server::registerServer($server); XML_RPC5_Server::run(); ?> The best thing is that basic methods in the interface or the server are ignored when creating the method lists. Also, by putting a "@noxmlrpc" tag anywhere in a docblock, a method will be ignored. Only public methods will be exposed, obviously. So, then the question is raised - what does PEAR want to do, assuming the code is liked? Should I propose XML_RPC5 through PEPr? Or just keep it off-pear in my chiara channel? I will be using it in Chiara_Server to cut LOADS of code away from the xml-rpc stuff and remove the xmlrpc extension dep. It would also be wonderful for PEAR2, but that is a long ways off. Needless to say, this is a pure php5-only implementation (I might enter it in the Zend contest, who knows) that uses lots of php5-only features (__call(), reflection, exceptions, interfaces, PPP, simplexml), and can't be backported at all.
