I did some Java, but I'm really swamped. You may get away with very simple changes that you probably can do yourself (like here ). Possible problem areas however are anything that interfaces with storage, especially when it requires write access (like loading and saving your designs), because an applet runs in the protected browser environment and has no direct local disk access. OTOH you may consider what they say here about Java Web Start . When you run an applet in a page, you have to first download it. This is not any faster nor much different from downloading the Java application. I'm not sure what exactly the problem is you're trying to solve with the conversion to an applet. Running a Java app can be as simple as downloading the jar file and double-clicking on it, and you're done with it.
