HT4314 How to connect Game Center to another Facebook account?

Question

Hi,
Please tell me how to connect my Game Center app to a new Facebook account. I tried to do it from the iPad Settings menu but there were no such option...

If you're using MIDP 1, which is what you need if you plan on deploying the game on an available phone, then the only protocol that you can count on being supported is Http. So if you're looking for portability across a large number of devices then that's what you should use (HttpConnection specifically). Also, since there is no push architecture in MIDP 1, you'll need to use the technique called "polling", which means you're clients are going to have to send requests to the server every few seconds to check for updates in the game.
I actually did a little 2 player tic tac toe to teach myself MIDP, and the code is available at planet source code:
http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=3398&lngWId=2
(If the link doesn't work just make a search for MIDP under the Java section).
You have to add a line to the JAD file that has the URL of the servlet, or you can replace:
String url = getAppProperty("TicTacToe.URL");in sendMessage() with a hard-coded string.
The servlet is very very crude, since I have little experience using Java on the server side and I was more interested in doing the client, and it just links the first two available players and automatically starts a game. But I think it might serve as good starting point for you. And of course, if you are more comfortable with other server-side technologies then you should use them instead of a servlet.
