i already connect to internet.

but if im trying to access the site, it only gives me the code (page source) of it.

why is that?

HttpConnection is a request-response protocol. It will help you send and receive data, but not to re-build accessed web page on your device. To build and application that will able to interpret web coding you would have to build mobile web browser such as Opera.
However if you just wish to upload/download or send/receive data from web server, perhaps also link to database, HttpConnection is what you need to use
