How Can I Patch a Java Application?

[raisenero]

Can anyone point me to a resource that contains any information on
patching a Java destop application once it has been deployed? I'm sure
the standard Java library must contain facilities I can use to build a
patch program but I'm not sure where to begin looking.

Sorry but need more information. What do you mean by 'patching a java
app after it has been deployed?'

Thanks in Advance...

I mean by replacing the .class files that are contained inside a .jar
file.

The simplest thing is to make a new jar of the replacement classes, and put
it first in the class path.

JavaWebStart (Part of J2SE), and its ability to deploy patches from
jdiff files - if you get it to work. Sun claims it just works, but there
are many people who say they can't get it to work.
