Error connecting with login URI

[Abel Fernández del Pino]

Hi,
I'm a newbie on Google API. I've read the documentation but I have an error whith autentication that I don't know how to solve it.
My code is:

import com.google.gdata.client.docs.DocsService;
import com.google.gdata.data.docs.DocumentListEntry;
import com.google.gdata.data.docs.DocumentListFeed;
import java.net.URL;

public class Docs{
    public static void main(String[] args){
        try{
            System.getProperties().put("http.proxySet", "true" );
            System.getProperties().put("http.proxyHost", "proxy" );
            System.getProperties().put("http.proxyPort", "port" );
            System.getProperties().put("http.proxyUser", "user");
            System.getProperties().put("http.proxyPassword", "pwd");
           
            URL url_feed=new URL("https://docs.google.com/feeds/documents/private/full");           
            DocsService client = new DocsService("UIC-GDocs-v1");
            System.out.println("authenticating ....");
            client.setUserCredentials("myu...@gmail.com", "mypwd",ClientLoginAccountType.HOSTED_OR_GOOGLE); //Line with the error
            System.out.println("authenticated.");
            DocumentListFeed feed=client.getFeed(url_feed, DocumentListFeed.class);
            for(DocumentListEntry entry : feed.getEntries()){
               System.out.println(entry.getTitle().getPlainText());               
            }
        }catch (Exception ex){
            System.err.println("Exception: "+ex.getMessage());
            ex.printStackTrace();
        }
    }   
}

And the error is:

authenticating ....

Are you trying to use the Client Login Procedure?
