Sending http request

[shivang sarawagi]

Hi Friends,

I just need a little help. Kind of stranded don't know how to proceed. If you could please help me out.

I am developing a facebook application in java. For that I have to go through an authentication process for the app.

These are the steps

1.Create a Facebook Application

2. Request https://graph.facebook.com/oauth/authorize?client_id=MY_API_KEY& redirect_uri=http://www.facebook.com/connect/login_success.html&
scope=publish_stream,offline_access,create_event

3.Facebook will redirect you to http://www.facebook.com/connect/login_success.html? code=MY_VERIFICATION_CODE

4.Request https://graph.facebook.com/oauth/access_token?client_id=MY_API_KEY& redirect_uri=http://www.facebook.com/connect/login_success.html& client_secret=MY_APP_SECRET&code=MY_VERIFICATION_CODE

5.Facebook will respond with access_token=MY_ACCESS_TOKEN

For the second step I used response.sendRedirect(); and sent the request. But as per the third request when the facebook redirects me to a url its just a page with
success written in it. Now I don't know how to proceed with the 4th step. How do I extract the verification code and send the request again.

Can you please tell is there any way to send the request again, maintaining the flow of the app.

Thanks
