Interesting thread!
With the XSLT transformation of the config file, it should be pretty
easy to experiment with these patterns.
I have mixed opinions about using controller chaining so extensively. I
can't imagine the performance cost of all the RequestDispatcher forwards
is a good thing.
Why not use the ControllerSingleton base and use the init() method to
set up your own composition scheme?
<command name="foo">
<controller class="blah.ComposedController">
<component class="blah.ComponentOne"/>
<component class="blah.ComponentTwo"/>
</controller>
</command>
You would have to define the interfaces for your composition scheme, but
this can be tailored a lot easier than trying to force everything
through the Dispatcher.
