I have a Java program, which launches a app, but before starting, it checks for the version.txt file, and if it doesn't exist, or there is a newer version available off my site, it downloads it. Well, not quite. I've got the part that checks for updates, and file existence, but not the updating part. I'm hoping I could make a launcher similar to the Minecraft game updater. So, I'll check for newer versions, and if one is available, it downloads the required files, and with a progress bar.
Thanks, Matthew.

Oops, forgot to say that..
I've found some tutorials on Google about downloading files in Java, but I'd like to build it so that I have a progress bar, and it downloads it in zip format, to keep files smaller, and make updating quicker.

well, use one of the tutorials, to download/check if the update exists, here is a tutorial on jProgressBars:http://docs.oracle.com/javase/tutorial/uiswing/components/progress.html then you would have to unzip the archive:http://java.sun.com/developer/technicalArticles/Programming/compression/ and then execute the update using the processbuilder class maybe:http://www.javabeat.net/tips/8-using-the-new-process-builder-class.html
