I'm not sure why you would want to load the JDBC driver in your JSP. JSPs
are part of the view layer. Your JDBC stuff should be way back in the
persistence layer. Even servlets are really too far forward for this - use
then more as controllers. Personally, I use JSP/Struts for the
view/controller and obtain back-end connections using JNDI. The datasource
name is provided as a servlet parameter in web.xml and is passed to the
data layer on session creation. You might find it useful to look at the
j2ee design patterns at java.sun.com.
