Java updating

[Reason7194]

Hello everyone, I have been searching google for decent tutorials on starting to learn how to create a program thought could be updated remotely. Possibly a window on the program could be updated to "Apple and Nanners" where it was just originally just "Apples". Could anyone point me in the direction of locating a tutorial on how to start learning where to begin? I know that sql has to be combined with Java so that information could be sent to a database then the program could read from the database to be updated. At least that is my concept of what I think happens when a update happens.

the requirements don't seem to be fully spec'd out

If you just intend on doing a data update, then you can achieve data updates through api calls to a authoritative source and a persistence layer on the client side.

If you intend to do binary updates, theres many different approaches you can take. The firefox method, which is download a completely new binary, swap and restart or you can do it the chrome way and download a binary diff (specialized compressed bsdiff in chromes case) and patch the binary diff against the binary and restart.

Reason7194,

i coded it by writing to a file, or downloading a complete .jar and then start the new version via process exec.

there are way better solutions (update deamon, updating single classes etc.) but i think this one is the easiest to start with.
