Solution 1:

Its located user /usr/share/tomcat7/lib folder. If you have used apt-get install tomcat7 command for installing your container.

Solution 2:

CATALINA_BASE:   /usr/share/tomcat7
CATALINA_HOME:   /usr/share/tomcat7
CATALINA_TMPDIR: /usr/share/tomcat7/temp

CATALINA_HOME/lib is therefore /usr/share/tomcat7/lib


To be sure, search for bootstrap.jar. This file is located in $CATALINA_HOME/bin/
