I'm trying to run an application on Tomcat. It fails to run, throwing a null driver class exception. I've already copied a jar file with a Db2 driver class (I'm using Db2 database) into Tomcat's /common/lib directory. But it still throws the same exception. What might be the problem here?
The exception is:
java.sql.SQLException Cannot load JDBC driver class 'null'
at org.apache.commons.dbpc.BasicDataSource.createDataSource(...)
at org.apache.commons.dbpc.BasicDataSource.getConnection(...)
etc...

I would interpret this error:

java.sql.SQLException Cannot load JDBC driver class 'null'


as a null reference being supplied in your code where you expect to have a String with a fully qualified class name.
If it was my problem I would try to print out or log the name of the driver class just before you call createDataSource.

You are mistaking quantity for quality.

This is the 3rd time you've asked this question, without any increase in the level of detail you are offering.

If you're not getting the answer you want:

1) provide more details about your settings or code
2) do so in the *same* thread, and don't start a new one.

Thanks.
