xml rpc...

[francisco_viola]

Hi!
I submitted this example:
"
<?php

require_once("XML/RPC/Server.php");

ob_start();

function hello($args)
{
/ O método getValues() retorna um array com todos os
parâmetros passados à função, convertidos de
tipos XML RPC para tipos PHP com a
função XML_RPC_decode()/

 $vals= $args->getValues();

/ nós simplesmente retornamos um XML_RPC_Values contendo o
resultado com o tipo 'string'/

 $out="Hi {$vals[0]} !";
 $val = new XML_RPC_Value($out, 'string');
  return new XML_RPC_Response($val);

}

function add($args){
$vals=$args->getValues();

  $out=$vals[0] + $vals[1];
  $val = new XML_RPC_Value($out, 'double');
  return new XML_RPC_Response($val);

}

$methods=array(
'hello' => array(
'function' => 'hello',
'signature' => array(
array(
$GLOBALS['XML_RPC_String'],
$GLOBALS['XML_RPC_String']
)
),

         'docstring' => 'Greets you.'
        ),



        'add' => array (
           'function' => 'add',
           'signature' => array(
              array(
                    $GLOBALS['XML_RPC_Double'],
                    $GLOBALS['XML_RPC_Double'],
                    $GLOBALS['XML_RPC_Double']
              )
           ),
           'docstring' => 'Adds two numbers'
        )


);

$server = new XML_RPC_Server($methods);

?>
"
and I had this result:
"

    This XML file does not appear to have any style information associated with it. The document tree is shown below.
  ...
    faultCode
    105
  ...

    faultString
    XML error: Invalid document end at line 1

..

"
could someone help me to understand what is the problem?

thanks
francisco
