Jsvc is a set of libraries and applications that facilitates running Java applications on UNIX. In the context of JBoss Enterprise Web Server 2.1, Jsvc allows Tomcat to switch identities. Using Jsvc, Tomcat can perform root user level operations and then revert to a non-privileged user. Jsvc is mainly used for running Tomcat as a service in the background.
For JBoss Enterprise Server 2.1, Jsvc files are available at the following locations:
For Red Hat Enterprise Linux:
jboss-ews-2.1/extras/jsvcjboss-ews-2.1/tomcat6/bin/jsvcjboss-ews-2.1/tomcat7/bin/jsvc
Note
Jsvc in Tomcat 6 and Tomcat 7 folders are symlinks to
extra/jsvc in the following way:
./jboss-ews-2.1/tomcat6/bin/jsvc -> ../../extras/jsvc
./jboss-ews-2.1/tomcat7/bin/jsvc -> ../../extras/jsvc
For Solaris:
./jboss-ews-2.1/sbin/jsvc./jboss-ews-2.1/share/apache-tomcat-6.0.41/bin/jsvc./jboss-ews-2.1/share/apache-tomcat-7.0.54/bin/jsvc
Note
Jsvc in apache-tomcat-6.0.41 and apache-tomcat-7.0.54 folders are symlinks to
sbin/jsvc in the following way:
./jboss-ews-2.1/share/apache-tomcat-7.0.54/bin/jsvc -> ../../../sbin/jsvc
./jboss-ews-2.1/share/apache-tomcat-6.0.41/bin/jsvc -> ../../../sbin/jsvc
