Error in simple Java code to invoke roller's metaweblog xml-rpc

[pein]

Hi, I have the following code:
       try {
            XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
            config.setServerURL(new
URL("http://localhost:8080/roller/giggs";));
            XmlRpcClient client = new XmlRpcClient();
            client.setConfig(config);
            Hashtable h = new Hashtable();
            h.put("description","from xml-rpc");
            h.put("title","test post from xml-rpc");
            Object[] params = new Object[]{"Blog ID", "giggs11x", "123", h,
true};
            System.out.println("here");
            String result = (String)client.execute("metaWeblog.newPost",
params);
            System.out.println(result);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

And i got the following error:
[Fatal Error] :1:63: White spaces are required between publicId and
systemId.
