RE: [Wrapper-user] Self Updating Application

[<nic...@uk...>]

You cant change a jar's contents - you can only create a new jar - and in
any case the file lock will prevent you.

George,
What you are wanting to do here is "hot deployment" like most application
servers / servlet engines have...

If you can use an appserver/servlet engine, then maybe you want to have a
look at:
1) JNLP - Its what is used for Java Web Start - but it you can use the JNLP
framework to do updates for anything.. server included.
2) OSGI

Maybe leave the jar as it is, but change its contents?
Like changing the chair that you (the java app) are sitting on..
You may get classloader problems if you do such a thing.

Onderwerp: [Wrapper-user] Self Updating Application

Does anybody know io a good way to have the wrapper service restart the jvm
with an updated version of the jar the contains app that is running? I want
to make my service self updating but I can't replace the jar file because
Windows has it locked.
