What the heck is jexec?
April 2nd, 2009
Recently I installed JDK 6 on my CentOS instance. I noticed a weird service called jexec running on all run levels:
jexec 0:on 1:on 2:on 3:on 4:on 5:on 6:on
Googled and found this installation notes from Sun:
A new service script, named jexec, is added to /etc/init.d. This script allows users to directly execute any standalone JAR file that has an execution permission set.
OK, so it’s for executing jar files.. A tiny little bit more convenient than using java -jar, but no thanks, especially on a server.
One less thing to worry about: chkconfig –level 0123456 jexec off
