In Canvas –Give the callback url of your application


We can start coding the application now.

Create the Twitter object & get the request token by passing the application Consumer key & secret.

To get the user client

FacebookJsonRestClient class is used for getting user client returns the object in JSON format.

FacebookJsonRestClient userClient =getUserClientsession);

public static FacebookJsonRestClient.getUserClient(HttpSession session) { 

  return (FacebookJsonRestClient)session.getAttribute(FACEBOOK_USER_CLIENT); 

}

User session doesn't have a Facebook API client setup yet.

Pass the API key & Application secret to get the valid userclient
And store it in a session.

     userClient = new FacebookJsonRestClient(api_key, secret); 

     session.setAttribute(FACEBOOK_USER_CLIENT, userClient);

Pass the Facebook url with your api key & required permission redirect the call.

You can check the permission available in Facebook .

 facebook = new FacebookWebappHelper(req, res, api_key, secret); 

 nextPage = req.getRequestURI();

 nextPage = nextPage.substring(nextPage.indexOf("/", 1) + 1); 

 //cut out the first /, the context path and the 2nd / 

 System.out.println(nextPage);

 boolean redirectOccurred = facebook.requireLogin(nextPage);                   

if(redirectOccurred){

         res.sendRedirect("http://www.facebook.com/login.php?api_key=dbfc65d0e72f5c103gg0gfgd8c5&connect_display=popup&v=1.0&next=http://www.facebook.com/connect/login_success.html&cancel_url=http://www.facebook.com/connect/login_failure.html&fbconnect=true&return_session=true&session_key_only=true&req_perms=read_stream,publish_stream,offline_access,sms,email,user_location");

Long  facebookUserID = userClient.users_getLoggedInUser();

To get friends Id’s

JSONArray arrayObj = (JSONArray)userClient.friends_get();

Get the id’s from Array & store it in a list

List userIds = new ArrayList();

for(int i=0;i try {								

   userIds.add((arrayObj.getString(i));

 } catch (JSONException e) {

	e.printStackTrace();

 }

}

Set the necessary fields in the ProfileField,that you need from a
User.

EnumSet fields = EnumSet.of (                  	            com.google.code.facebookapi.ProfileField.NAME,                  	            com.google.code.facebookapi.ProfileField.PIC,                                        com.google.code.facebookapi.ProfileField.CURRENT_LOCATION, com.google.code.facebookapi.ProfileField.FIRST_NAME, com.google.code.facebookapi.ProfileField.LAST_NAME);

  JSONArray userArray = null;

   try {

	userArray = client.users_getInfo(userIds, fields);

       } catch (FacebookException e1) {	

        e1.printStackTrace();

       }

       for(int i=0;i< userArray.length();i++){

   try {						

	  for (int j = 0; j < userArray.length(); j++) {

           JSONObject obj = userArray.getJSONObject(j);

           System.out.println("User Id"+obj.getString("uid"));

           System.out.println("Pic url "+obj.getString("pic"));

           System.out.println("Name"+obj.getString("first_name")
