Chapter 5. Using Jsvc to Start Tomcat
Jsvc is a set of libraries and applications that facilitates running Java applications on Linux, UNIX, and similar operating systems. Using Jsvc with JBoss Web Server allows Tomcat to switch identities. Using Jsvc, Tomcat can perform root-level operations and then revert to a non-privileged user. Jsvc is primarily used for running Tomcat as a service.
Jsvc files are available at the following locations:
-
JWS_HOME/tomcat/bin/jsvc JWS_HOME/jbcs-jsvc-1.0/sbin/jsvcNoteJWS_HOME/bin/jsvcis a symlink toJWS_HOME/jbcs-jsvc-1.0/sbin/jsvc.
