Socket to stream data over internet (with Xport)?

I am just looking to see if anyone has experience doing this. I have had a look at some of the examples on

http://www.arduino.cc/playground/Interfacing/SerialNet

If I am not mistaken, most of them require a computer based server (connected via USB or similar). I am hoping to simply have a standalone Arduino to do this. A friend has suggested to me to try programming a java applet to put on the xport server (which supports java), and write a socket this way.

Is that viable? If so, any idea how I should get started, unfortunately my experience with java is next to nil… I have also seen some javascript-based socket options around, but other than them having the word, socket, in common, I am really not sure how to start.

Any help would be much appreicated!
