They don't? Have you checked out the "Tutorial Live Examples"? It uses
definitions, in a step-by-step way, too.

Actually, you don't need this here; the one in the plug-in declaration
does fine.

Unless it's a typo, rename it to "tiles-defs.xml". ;)

Are you saying that it works if you change
<action path="/login" forward="fulluser"/>
to <action path="/login" forward="something.jsp"/> ? I'm pretty
uncomfortable with the "/do" prefixing the "/login" in your html:link
tag (not that I've tried it).
