Hi list!
I am trying to configure apache + tomcat using mod_jk on different machines
with virtual hosts, i.e one frontend running apache (2.2.3-4+etch4), one
backend running tomcat 6 (binary apache-tomcat-6.0.16) with postgresql
(postgresql-8.1, 8.1.11-0etch1) on debian etch.
My virtual host is called myapp.mydomain.com.
The problem is that when I am using context in my virtual host config for
tomcat I receive the following in my logfile, catalina.out,

If I try to connect to my vhost now everything looks ok, no errors anywhere,
but when I try to login I get a message that the database is not online and in
my logfile I see this:
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of
class '' for connect UR
Dan,
This has been discussed many times before. Usually adding the database
driver to $TOMCAT_HOME/lib or $TOMCAT_HOME/common/lib
solves the problem.
Also further information maybe found at the following URL from the
mailing list archive, which is a good way to search for previously
discussed issues and solutions:
