First time using face4j, not a big J2EE expert either, so it might be some simple misstake.

I downloaded the libraries, addded both dependencies and the 1.7.1 jars to the Google Appengine project.

Servlet's code is:

package hu.edudroid.facebook_sample.server;

import java.io.IOException; import java.io.PrintWriter;

import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

import com.face4j.facebook.Client; import com.face4j.facebook.enums.Display; import com.face4j.facebook.enums.HttpClientType; import com.face4j.facebook.enums.Permission; import com.face4j.facebook.factory.FacebookFactory;

public class FacebookServlet extends HttpServlet {

private static final String APP_SECRET = "xxxxxx";
private static final String APP_ID = "xxxxxxxx";
private static final String REDIRECT_URL = "xxxxxxxxxxx";

private static final long serialVersionUID = -5750323052726353067L;

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    Client client = new Client(APP_ID, APP_SECRET);
    FacebookFactory facebookFactory = new FacebookFactory(client, HttpClientType.URL_FETCH_SERVICE);
    String redirectURL = facebookFactory.getRedirectURL(REDIRECT_URL, Display.POPUP, Permission.EMAIL, Permission.OFFLINE_ACCESS);
    System.out.println("Redirecting " + redirectURL);
    PrintWriter out = resp.getWriter();
    out.write(redirectURL);
    out.flush();
}

}

How could I make this work?

Never mind, my bad. It was not enough to add libraries to the project, but I had to copy it to WEB-INF/lib

Hi!

Thanks for the support. I have another problem: I'm progressing with the Facebook login, and have a problem with threads on appengine.

I got the following error. It seams that threads are not supported in appengine https://developers.google.com/appengine/docs/java/runtime#The_Sandbox. What is the workaround?

That error should not have happened. Please send me the code so that I can look into it.

Hi!

Sorry again, my mistake, I should sleep more. It was the error you pointed out in the tutorial, I used the wrong http client. Sorry for bothering you again. Now everything works fine, great library, thanks.
