What's the best way to add a self-update feature to a Java Swing application?

Question

I\'m trying to figure out a way to add a self-update feature to a Java/Swing application I\'m working on.

Basically I\'ve got a bunch of jar files with extra functio

Answer 1

we had a swing app 6 years ago that had self-update. like you suggested,

1)it downloaded the latest jars over http,
2) copied them to a folder.
3) since the swing app is launched using a .BAT file, after user said YES, we would shut down the swing app and look for any files in the update folder. if yes, launch another .BAT file to copy the NEW JARs to the required directory.
4) then re launch the swing app.
