This is not a JDBC related issue, you should ask that to the
tomcat lists - but normally, you can either put the JAR in
tomcat/shared/lib so that it's visible, shared and used by all
your web applications, or inside the WEB-INF/lib directory of the
docbase of your application(s) so that it's loaded only for your
application(s).

Hello Moien,

Usually the following locations should do:

<tomcat_home>/common/lib (at least in Tomcat 5.5)
<webapp>/WEB-INF/lib

I wonder WHICH class it is your tomcat cannot find.
Please post the jsp, esspecially the import declarations at the top.

If you can try Tomcat 5.5 or JDK 1.6

Daniel Migowski
