Nope. The situation is this:
** I check online for updates to a Java program I'm writing.
** If I find one, I download it and execute it; in this case, it's an
installer that will overwrite the program's JARs, etc., so I want the
program to NOT be running while the installer is running.
Perhaps ProcessBuilder.start() isn't the right approach to use.
I've had a similar problem. We had an application that we wanted to do
remote updating on. We sent the file and wrote it out to disk with a
different name than the current program and then started it with Process
just like you are doing. Jar files don't need the .jar extension to
work by the way. This wasn't a 100% successful and the project folded
up anyway so we didn't pursue it to a conclusion. Buy my last thought
on the subject was to use a control program to load the actual program
from disk. This way the files could be overwritten or at least I think
they can be. It appears to be a conundrum and if you come up with a
good solution, please post it here.
