Are these servlets with JDBC code in them, or just servlets testing Tomcat?

If you're getting the error when running from the command line, then this
has nothing to do with Tomcat.

The problem that seems to plague many new users of Tomcat is that since
Tomcat runs as a detached process, new developers often forget to add the
jdbc jar file to the classpath for the Tomcat process, or have trouble
figuring out how to do this.

Which line of the code is referenced for the  'NoClassDefFoundError' ?

I think there's a brief sql tutorial in the postgresql docs on-line. You
might also want to check out Bruce Momjian's book, which is still on-line in
html: http://www.ca.postgresql.org/docs/aw_pgsql_book/index.html. He has a
gentle intro to SQL in the psql environment.
