Hi All,

I am for an application which extracts information from facebook search, hence i require to login facebook. i have registered my application in facebook developers site and have got api key and secret key. in my code i am getting an exception when i am trying to login. Here is my code for login to facebook:

import com.facebook.api.FacebookRestClient; import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpState; import org.apache.commons.httpclient.NameValuePair; import org.apache.commons.httpclient.methods.GetMethod; import org.apache.commons.httpclient.methods.PostMethod; import org.apache.commons.httpclient.params.HttpClientParams;

public class FaceLogin { public FaceLogin(){ getUserID("username", "password"); }

private static void getUserID(String email, String password) { String session = null; try { HttpClient http = new HttpClient(); http.setParams(new HttpClientParams()); //http.getHostConfiguration().setHost("http://www.facebook.com/"); http.setState(new HttpState()); String api_key = "****some key****";
String secret = "****some key****";
FacebookRestClient client = new FacebookRestClient(api_key, secret); client.setIsDesktop(true);

        String token = client.auth_createToken();
        final String loginId = "http://www.facebook.com/login.php";
        GetMethod get = new GetMethod(loginId + "?api_key=" + api_key + "&v=1.0&auth_token=" +token);
        System.out.println("Get="+get);
        http.executeMethod(get);

        PostMethod post = new PostMethod(loginId);

        post.addParameter(new NameValuePair("api_key", api_key));
        post.addParameter(new NameValuePair("v", "1.0"));
        post.addParameter(new NameValuePair("auth_token", token));
        post.addParameter(new NameValuePair("fbconnect","true"));
        post.addParameter(new NameValuePair("return_session","true"));
        post.addParameter(new NameValuePair("session_key_only","true"));
        post.addParameter(new NameValuePair("req_perms","read_stream,publish_stream"));
        post.addParameter(new NameValuePair("lsd","8HYdi"));
        post.addParameter(new NameValuePair("locale","en_US"));
        post.addParameter(new NameValuePair("persistent","1"));
        post.addParameter(new NameValuePair("email", email));
        post.addParameter(new NameValuePair("pass", password));


        System.out.println("Token ="+token);
        int postStatus = http.executeMethod(post);
        System.out.println("Response : " + postStatus);

        session = client.auth_getSession(token);                            // Here I am getting error
        System.out.println("Session string: " + session);
        long userid = client.users_getLoggedInUser();
        System.out.println("User Id is : " + userid);

    } catch (Exception e) {
        e.printStackTrace();

    }
}
public static void main(String k[])
{
    FaceLogin facebookLoginObj=new FaceLogin();
}

}

I am getting the following exception:
