Could someone just look at this code and point out the obvious errors. It may or may not be obvious on what it is supposed to do. Never the less what I want it to do and the syntex are bad. Could someone just make observations on how to accomplish different aspects of common code practices.

Ideally there should be 'zero' Java code in your JSP file. Use JSTL's instead which help in separating the business and presentation to a greater extent. A brief tutorial here.
