start and stop antville/antclick properly

Hello, as mentioned earlier in the helpfiles or faq you start antclick (in my case the java-only version including webserver jetty and database mckoi) on a linux system with nohup ./antclick.sh &

looking for the antville/java processes (eg. ps -x) on the system the shell skript invokes 21 java processes

how do you shut antville down properly? what process has to be 'kill'ed? The kill command is fine, but doesn't you risk to corrupt, for instance, the database?
