How do I get the id of my Java process? I know there are several platform-dependent hacks, but I'd prefer a more generic solution.
There exists no platform-independent way that can be guaranteed to work in all jvm implementations.
ManagementFactory.getRuntimeMXBean().getName() looks like the best (closest) solution. It's short, and probably works in every implementation in wide use.
On linux+windows it returns a value like
12345 being the process id). Beware though that according to the docs, there are no guarantees about this value:
Returns the name representing the running Java virtual machine. The returned name string can be any arbitrary string and a Java virtual machine implementation can choose to embed platform-specific useful information in the returned name string. Each running virtual machine could have a different name.
