I am building a mobile webapp and need to pull and push data to OpenERP V7.

If I understood the only way to communicate with OpenERP is XML-RPC or JSON-RPC.

Questions: 1/ I found document with XMLRPC but not for JSON. Any idea where I can get it ? 2/ Testing XMLRPC with Javascript and jquery.xmlrpc.js

I wrote :

  $.xmlrpc({
    url: 'http://mySErverName:8069/xmlrpc/common',
    methodName: 'login',
    params: ['myDb', 'admin', 'password'],
    success: function(response, status, jqXHR) { alert('OK')},
    error: function(jqXHR, status, error) { alert('Error : ' + error.debug ) }
    });

But when executing, function error is executed but error has no value inside. So I don't what's wrong.

What is the best way to use xmlrpc with Javascript ? What is wrong with the code I posted ?
