How to write a self-updating program in Java? [closed]

Question

How can i make a Java program which can update itself. I make this program for use within small team. I do not need any advanced features. I just need a simple and minimal solution.

Answer 1

Java Web Start is meant specifically for this. You ship one jnlp file, and java takes care of fetching the newest version from a server.

Apart from that, you can download updated classes and replace them at runtime.
