Hi,
Put the JDBC jar in [TOMCAT]/common/lib
Do not place it inside your own application lib folder

Assunto: jndi error configuring data source
I am trying to configure database pooling in Tomcat 4.1.31. I found some
excellent documentation here
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples
-howto.html
I followed this exactly for mysql (top article).
I created the DBTest web-app precisely, and all folders exist and
web.xml file is good.
My webapp is under root/DBTest/WEB-INF/classes
/lib/mm.mysql-bin.jar
web.xml
The server starts properly, so I know my configuration is good. The
problem is I get an error stating that it cannot find the jar file for
the mysql driver when I hit the test page. (ERROR_BELOW)
Anyway, I followed the article precisely, and noticed that they hit
localhost:8080. My tomcat is running on 80 and at my IP address as you
can see below.
Would this be why it cannot find the jar file? I am looking at the ajp13
listening on /0.0.0.0:8009 and wondering if there is something else that
needs configuring?
Would like to get this running if possible.
Thank you
Scott
