Creator Tomcat MySQL Deployment Table Not being filled by DB

Question

Hi All,
I am deploying a Creator app called test3.war which uses a MySQL db called RemoteFocalPoint.
When I try to browse to the url : http://65.99.196.145:8080/test3/ The page wont load I have also had the error JasperException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
I can get the table to be filled from the RemoteFocalPoint db on a sun pointbase server running locally with the following parameters :
Data Source Name : RemoteFocalPoint
User ID : root
Password ; ****************
Data base URL jdbc:mysql://65.99.196.145/RemoteFocalPoint
Driver Class : org.gjt.mm.mysql.Driver
Validation table : Validation
I have installed Tomcat Administrator for the production Tomcat (v5.5) environment.
The settings I have on Tomcat Administrator for http://65.99.196.145:8080/test3/ are
JNDI Name: jdbc/RemoteFocalPoint
Data Source URL: jdbc:mysql://localhost/RemoteFocalPoint
JDBC Driver Class: org.gjt.mm.mysql.Driver
User name jim
Password *****************
Max. Active Connections: 4
Max. Idle Connections: 2
Max. Wait for Connection: 5000
Validation Query: SELECT ALL VALIDATION.Test FROM VALIDATION
If anyone could shed any light on this I would be grateful. There is a lot of contradictory information on the web about this issue.
Regards

I think that his has been answered better than I can elsewhere in the forum and
on the web. It's something that people frequently run into.
But effectively, I think you need to edit a <project>/web/META-INF/context.xml
file, adding something like this:
(replace "oms" with your project name).
Unfortnately, posting xml just doesn't work for me, but you ought to be able to google
for context.xml, tomcat, resource and maybe database.
I believe Dion Almaer has a post in his blog about it.
