I have a program allowing script files to “compete” with each other in a games such as Tic Tac Toe .

The visualization is made in the console and looks something like this:

|  XO |
| OX O|
|  X  |
- X is the winner! Meh..

Not very exciting.

I was thinking of making a Swing visualisation, but after seeing a presentation on the Raphaël JavaScript vector graphics library I decided that I’d be cool to make the visualization browser based, even though every thing will be running on the same computer.

Do I need a full fledged web server to accommodate for this? How does the JavaScript communicate with the Java program?

    Building a Swing interface would be the most straightforward solution, but this would probably be the messiest one as well.

    The web browser solution is probably the most satisfying if you already have a web server going, but has a lot of overhead to set up and properly understand. Then again, you have layers of different technology to play with and get confused in (java, JSP, HTML, javascript, css, etc).

    These days, with HTML5 and available javascript libraries, the web interface is in my opinion the best choice for most interfaces, so you might as well set up your machine and have it available for the next project.

    Any communication between the server (Java) and the browser will take place with a HTTP request from the browser.

    This may happen in two ways:

    a) By pressing a submit button on a browser HTML page and rendering a HTML page on the server as a response (usually through server side scripting like JSP, although you could generate the entire page through java code)

    b) By using Ajax in javascript to make an asynchronous call to the server, which will respond with data that you can then interpret and render with javascript (probably the best solution for what you are trying to do). There are many ready javascript libraries to help you with this, including jQuery.

    In method b, you would essentially be waiting on the server side for a post from the browser and then you would be responding with a page written in XML, json or even pure text. Your javascript code would then interpret the data and render it on the browser HTML page (which you will have loaded at the starting point for the application).
