#18501 — automatically updating application

Hi. 
I'm developing application that has to automatically update. 
Now it works as a windows service (using prunsrv http://commons.apache.org/daemon/procrun.html ) 
I'm wondering if you have any ideas that will help  

the plan is much about: 
1. application downloads update package 
2. application runs update package and ends itself 
3. update package do update (java classes or maybe a script ? ) 
4. update package ends and starts application (starts windows service) 

using java during update is easy/comfortable ? or maybe some kind of scripts? BeanShell? (i don't want to learn a new scripting language - i don't have a time for this  ) 
are there any advantages of using scripting languages? (over plain java)

If you do not have time to do it right the first time, then you will
most likely end up spending way too much time on it.

Have you checked out whether you can use OSGI?

     Have you looked at Java Web Start?  (If "Yes" and it won't
work for you, please describe where it lets you down: Maybe
someone knows a way to have it pick you up again.)

Eureka! I've always felt that JWS could exert a buoyant force.

Andrew Thompson has helpfully summarized related information here:

If a Windows service can use Java Web Start then it will certainly
be simpler than OSGI.

but rather because its opponents eventually die, and a new generation grows up that is familiar with it.
