How to get a token for Facebook using only login and password?

'm working on proxy XMPP that listen on port 5222 for Gtalk and I need token to change the request of users and sent it to the server that's why I use this url:

String url = "http://ift.tt/wFWebw?" +
            "accountType=GOOGLE&Email=" + user + "&Passwd=" +
            password + "&service=mail";

which give me token and I can work. But I need to do the same thing for facebook but I can't find an url that does the same thing, I found this

http://ift.tt/1vhxeqF...

But there are many parameters that I don't have like redirect_uri it's for my web service, but I don't have a web service, I just need it for a proxy... Someone can help me to have a dynamic token for facebook using only login and password?
