null driver class exception

[Nhlanhla Dlamini]

I'm trying to run an application on Tomcat. I get the following exception:
java.sql.SQLException: Cannot load JDBC driver class 'null'
at org.apache.commons.dbcp.BasicDataSource.createDataSource(...)
at org.apache.commons.dbcp.BasicDataSource.getConnection(...)
etc...
What's the problem?

you haven't configured your JNDI DataSource correctly.
