tomcat won't load oracle driver
I have Tomcat 3.3 and cannot get any web apps to recognize the oracle jdbc drivers, which are contained in an oracle file named classes111.zip. I am confident of the oracle installation, as I can successfully run queries from command line java programs, using the same class file and driver. The system out always indicates that tomcat cannot find the oracle driver.
Predictably, I have already tried moving the oracle class file among many directories under %TOMCAT_HOME%, including lib, apps, common, container, and of course, I have also placed it at various locations within the web-app\<application> directory sub-dirs. I always restart tomcat after moving the class file.
Nothing works. Tomcat cannot or *will* not find my oracle class file.
Advice appreciated!

I haven't tried this, but maybe Tomcat has a problem recognizing the
.zip extension. zip and jar are interchangeable. Maybe see if you can
either rename it to classes111.zip or unzip it and re-package it with a
.jar extension. Then try putting it back in the lib/apps directory.
I've had the best luck with classloader and the apps directory with
version 3.3.

I was under the impression that you put Jar's in the %CATALINA%\lib
folder and class files in the %CATALINA%\classes folder. The
documentation does not talk about zip files. So my recommendation would
be to extract all your classes into the %CATALINA%\classes folder and go
from there.
Here's a link to the documentation

he could extract them and place them in his classpath, that has to work.

Someone mentioned on -dev that one has to remove the java*.sql
classes from the oracle jdbc jar in order to work with jdk 1.4
(since 1.4 began bundling these classes as well)
