For interceptor docs, this is a good start...

Also, I'm a little confused about what "beans" you're binding to.  Your
action does not expose a bean/object, it simply exposes two Strings
that are properties of the action (username and password).

Not that there's really much difference between binding to properties
of a bean exposed by the action and binding to properties of the action
itself, but I just didn't want you to think you're doing something (bean
binding) that you don't appear to be doing.

If you want both your custom interceptor and the default-stack of
interceptors
to run for you action you can do this...

<action name="Logon!*" method="{1}" class="foo">
	<interceptor-ref name="LanguageFocusInterceptor"></interceptor-ref>
	<interceptor-ref name="default"></interceptor-ref>
	... the rest of the action definition goes here
</action>

Or you could define a new default stack that includes your custom
interceptor.  That's described here:
