[one-users] RPCXML response problem

[Joey]

Hi,

I refer to the ./src/oca/java/org/opennebula/client/Client.java. Its 
"call" method is defind as:

     public OneResponse call(String action, Object...args)
     {
         boolean success = false;
         String  msg = null;

         try
         {
             Object[] params = new Object[args.length + 1];

             params[0] = oneAuth;

             for(int i=0; i<args.length; i++)
                 params[i+1] = args[i];

*Object[] result = (Object[]) client.execute("one."+action, params);*

*success = (Boolean) result[0];*

             // In some cases, the xml-rpc response only has a boolean
             // OUT parameter
             if(result.length > 1)
             {
                 try
                 {
                     msg = (String) result[1];
                 }
                 catch (ClassCastException e)
                 {
                     // The result may be an Integer
*msg = ((Integer) result[1]).toString();*
                 }
             }


         }
         catch (XmlRpcException e)
         {
             msg = e.getMessage();
         }

         return new OneResponse(success, msg);
     }

You're right. Apologize for my incorrect advice. :-P
