Iain,
The RequestInitializableRequestProcessor interface from the example is
probably something you have to program yourself. Create that interface,
and have all your handler classes implement it with the "init" method.
This way when newPropertyHandlerMapping (that you are going to override)
is called, the mapping object that gets returned has a special
RequestProcessorFactoryFactory that initializes your handler for you --
with the "init()" method you implemented.
Does that make sense? I haven't tried this method myself, but I assume
there is a bug in the faq; in the example code we're talking about:
mapping.setRequestProcessorFactoryFactory(mapping);
should be:
mapping.setRequestProcessorFactoryFactory(factory);
In my application I have lots a global controller that manages access to
application objects, so in my handlers, I grab a static reference to
that controller, from which I can get at the objects (or whatever other
resources you need) of interest.
E.g.:
BlahObject blah = BlahObjectController.getBlah(id);
....
