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/jsvc

    Note

    JWS_HOME/bin/jsvc is a symlink to JWS_HOME/jbcs-jsvc-1.0/sbin/jsvc.
