You have two options: 1) the simplest (but I don't like it because it can cause some side effects): use a session-scoped form bean; 2) the action is called on the "onchange" event of the <select> tag. The new value of the select tag itself is submitted. You process it and you reput it inside the HttpServletRequest. In the JSP page, you can process it (e.g. with the use of EL) to show the previously selected value.
