title: Exception: Method not found: execute_kw
body: <p>I am calling create method of OpenERP through XMLRPC by:</p>
  
  <pre><code>Object[] valuesAllOL = new Object[]{ record };
  Object[] all = new Object[]{TINY_DB, uid, PASSWORD, tableName, CREATE_OP, valuesAllOL};
  
  Integer id = (Integer) xmlrpcClient.execute(COMMON_METHOD, all);
  </code></pre>
  
  <p>Where <code>record</code> is a <code>hashmap</code>.</p>
  
  <p>And:</p>
  
  <pre><code>COMMON_METHOD = "execute_kw";
  CREATE_OP = "create";
  </code></pre>
  
  <p>I've got the following error:</p>
  
  <pre><code>org.apache.xmlrpc.XmlRpcException: Traceback (most recent call last):
    File "/opt/odoo/openerp/service/wsgi_server.py", line 75, in xmlrpc_return
      result = openerp.http.dispatch_rpc(service, method, params)
    File "/opt/odoo/openerp/http.py", line 114, in dispatch_rpc
      result = dispatch(method, params)

      raise Exception("Method not found: %s" % method)
  Exception: Method not found: execute_kw

  <p>Any help would be appreciated</p>
