You seem to have a lot to learn. How far have you gone with Tomcat and JDBC before now? Have you made a simple Tomcat web application using JSPs that pulls data from a database? Here's a good tutorial on how to do that: http://www.informit.com/articles/art...&seqNum=5&rl=1
Once you have that web application set up, it's pretty simple to change it to a useBean-style application. Just abstract the results of the query into a typed object, and have a constructor on it that can fetch data from the database for field population. (Basically take all the JDBC code out of the JSP in the example and put it into your data access object (DAO).) Then your JSP code should be dedicated to the display of DAOs, not the fetching.
Let us know how far along you are and what specific problems you're running into. Good luck!
