Well, I'm not sure what sort of collection those are kept in. It may
not be ordered. My (pure) guess is that those get stored in a Hashmap
of sorts. That being the case, I don't think there's a way to determine
their original order - you'd have to "cook something up". You could:
- write a plugin to build an object-graph representing your
navigation console
- hack struts to use a different sort of collection
The plugin idea has some merit to it. You'll get a reference to the
application configuration for whichever module you're in. You could use
that to determine your links etc. What you'd probably do is something
along these lines:
- arrive at a design for your heirarchy
- arrive at a deisgn for an XML file that models that heirarchy
- use digester to parse the XML and create/populate your beans
- iterate through your beans and use some attribute of the bean to do a
lookup in the application config and retrieve the links you need
- set your bean properties per the action
- stuff your "top-level" bean out into application scope so you can
reference it later
Help any?
