What is happening is that JSP is using the Java "reflection" API (part of the standard
JDK) to look at your bean's class and
determine what properties it has that follow the usual JavaBeans setXxxxx naming
convention. Then, it checks the parameters that
came in with each request. For each name match, it calls your setXxxxx method for
that property.

Just the setXxxxx methods for the properties you want to have set from the request
parameters. For other reasons you will want
the getXxxxx methods as well, but they are not used to process the <jsp:setProperty>
element.
