Ensure that the form bean exists before the form tag is processed. This
is a simple (if not entirely clean) way of ensuring that the initial
values assigned during bean instantiation will be available within the
form, since reset() will not be called when the form bean already exists.
The right way to fix this is to modify this webapp so that it does not
refer directly to JSP pages, but goes through Action classes, and to
either modify the TestBean class, adding an initialize() method, or to
have an Action class set the initial values.
