where is the Tomcat 7 home / lib directory?

  • 772

When reading manuals / tutorials on setting up JDBC with Tomcat I frequently come across references to the "Tomcat's HOME\lib" directory. E.g.:

Add the driver to your classpath, to your project, or to Tomcat's HOME\lib directory.

Other times, reference is made to the "$CATALINA_HOME/lib" directory. E.g.:

Before you proceed, don't forget to copy the JDBC Driver's jar into $CATALINA_HOME/lib.

I am running Tomcat 7.0.53 and am aware of the following locations:

  1. /usr/share/tomcat7
  2. /var/lib/tomcat7 (where the webapps/ directory resides)
  3. /etc/tomcat7

Of the above location only /usr/share/tomcat7 contains a lib directory with jars. Is this the "Tomcat's HOME\lib" directory? What is then, the CATALINA_HOME/lib directory?

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

  2. CATALINA_HOME and Tomcat's HOME is usually the same:

    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/
