/usr/share/tomcat-6/lib/tomcat-dbcp.jar missing from www-servers/tomcat-6.0.16 It is present in the apache distribution and is necessary for connecting to a datasource - for example a database. In particular the class org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory is needed. Reproducible: Always Steps to Reproduce: 1. Start tomcat 2. look in /var/log/tomcat-6/catalina.out for the error 28-Mar-2008 12:09:45 org.apache.catalina.core.NamingContextListener addResource WARNING: Failed to register in JMX: javax.naming.NamingException: Could not create resource factory instance [Root exception is java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory] Actual Results: Downloading the vanilla tomcat from apache.org and symlinking in the jar solves the problem Note I believe that that above jar is NOT the same as commons-dbcp.jar, that is the class mentioned above is not therein. Tomcat repackages the classes (literaly :-) they have different package names.

It's quite stupid, and has been commented on by upstream. This is a known long time bug. Also mentioned on the Tomcat Guide, both 5.5 and 6. *** This bug has been marked as a duplicate of bug 144276 ***
