Tomcat Connection Pooling

Question

I am using Tomcat connection pooling (DBCP) to get the connection from the Database
It really works great with Oracle, MySQL, Sybase and as well as DB2.
Recently I tried to integrate apache with tomcat to improve the performance.
But now the problem is I am unable to load the JDBC Driver its giving me an error message as Cannot load JDBC driver class ?null?
@ org.apache.commons.dbcp.BasicDataSource.createDataSource ..
Interseting thing is I am able to get connection through datasource(DBCP) if I use the following URL
http://localhost:8080/application _name/Hello.jsp
But I get the error message when I try to get connection through datasource(DBCP)
as Cannot load JDBC driver class ?null? for this URL
http://localhost/application_name/Hello.jsp
Both the URL use same server.xml, httpd.conf,servlet class and jsp pages
Gurus can you please help me to understand why my application is unable to get the connection when I use this URL http://localhost/application_name/Hello.jsp
But not with other one
Please........... Some one help me
Thanks in Advance

Thanks for your reply
Yes I am doing context lookup like this
Context ctx = (Context) new InitialContext().lookup("java:comp/env");
conn = ((DataSource) ctx.lookup("jdbc/test")).getConnection();
This works with Tomcat but I am unable to make it work after
integrating tomcat with apache
Thanks for your help
