This is my fisrt Bug report so please be patient if it is not great.
I think this bug (or a version of it) has been causing users and me a lot of
problems (See
http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg88786.html)
I can not get the BasicDataSource to load its driver. I have tried every
possible combination of server.xml and web.xml definitions.
The tomcat administration complains about:
org.apache.jasper.JasperException: Exception retrieving attribute 'driverClassName'
When I start tomcat I get:
Starting service Tomcat-Standalone
Apache Tomcat/4.1.24
Cannot load JDBC driver class 'null'
