Kill only one Java process

view story

http://unix.stackexchange.com – I usually run few Java applications, one for server running locally and other for some IDE like NetBeans. And from time to time, after lots of redeployments, my server get stuck on OutOfMemoryException so I need to kill Java process in order to reboot. So I do pkill -9 java but this also kills my running IDE which I don't want to. So how do I kill only application linked to running server and not the other ones?I assume that they all are running under same process but there has to be some way how to distuingish them. (HowTos)
