how to change the name of a Java application process?
argv, java, process
Solution
These methods are suited for servers with a lot of java processes running, and where you need a quick way of finding the correct jvm (not using jps.) For applications, I suppose launch4j or another wrapper is the way to go.
On unix, If you are launching from a shell sript (at least for bash and possibly for other decent shells) you can use:
exec -a goodname java ...
to launch `java` and pass "goodname" as the 0th argument, which will be shown as the process name in `ps` etc.
A perhaps better alternative (that seems to work also for `top`) is to create a symlink: `ln -s /usr/bin/java /usr/local/bin/kallekula`.
Shortcuts in windows won't do the trick, but windows vista/7 supports symlinks using `mklink`. That may work, but I haven't tested. I am not sure if `exec -a` also works with cygwin bash on Windows.
Problem
When executing a Java application the process name given to it is usually `java.exe` or `javaw.exe`. But how can I make it be called by the name of my application?
