Typically, an Action will pass information via request attributes (or
sometimes session attributes), which can then be accessed by the view
layer. It's also very common for an action to prepopulate a form bean
that will be used in a subsequent view -- for an example of this, take a
glance at the code for the Struts example webapp, when you click the "Edit
your user registration profile" link.
