Integrate a Java stand alone application to the Web
<p>I develop Java applications with Eclipse that process data. So far I only developed stand alone applications that take data from file or database, process the data, and output the results to the console/file/database. </p>

<p>I would like put my application online. I never did any web development, but from my understanding, the only difference is that my code needs to be on a web server that can get http requests from users, and return http response based on my application's result. </p>

<p>I would like to get advice on the easiest way I can do this. What technology do I need to learn and what tools I can use for making the transition easier. I would also like to separate my code from the code related to the web stuff. </p>

<p>Thanks a lot! </p>
