Without stopping the JVM you want to change the files that the JVM is using?
I wonder. Hopefully, you can copy the files to another location, if the
application dont have any open inputstream. But the JVM current execution
path will not change if you donot restart it.
Thanks & Regards

On unix (posix, linux) systems you can move anything even when in use.
Files that are open will remain open, and the application will continue
to use them. Problems will arise when the application attempts to open
new files, because then they have to be at the expected location.
If you really want zero downtime, you can set up softlinks to make the
program believe that everything is still in its old location during the
transition phase.
On the other hand, if you prepare it well, you can stop, move and start
in a matter of seconds, and most users will never notice it was down.
And the risk of the whole thing crashing down because of some
peculiarity in the application due to the unexpected move is probably
big enough to want to avoid that situation.

I would be doing it on red hat. Would it just be easier to email all the
users and say its down for maintenance and then just move it?

I doubt you would even be able to do so, at least not in Windows.

No, that is not safe. Tomcat may access any file in a webapp at any
time, plus files in its work area.

Ok thanks what i meant is that the tomcat directory is in
~/tomcat6/apache-tomcat-6.0.20/ and i need to move it to my home directory
~/. Basically was it safe to do it while tomcat is still running.

Generally, no, you can't do that - if your not-quite-English question has been understood. It all depends on what you mean by "move the tomcat directory with in my user". Even renaming the directory may cause problems.
