Don, I would argue the opposite... I understand that you are going to have trouble in a resource-constrained environment, and as Musachy mentions later in the thread, there are things we could dump to regain space... But! Most of our users aren't resource-constrained... At least, if they are, they aren't complaining about it. If we moved infrequently used interceptors, results and all their supporting classes into plugins (which would be pretty easy, mostly due to your hard work), then that would just make it more difficult for the vast majority of users.
If you want to start a struts2-lite project, I'd be happy to jump in and help out, but I think that resource-constrained environments are the exception, not a rule to live by. -Wes On Mon, Dec 7, 2009 at 6:33 PM, Don Brown <mr...@twdata.org> wrote: > Well, two things: sharing an IoC container with the app is almost > always a bad idea in the long run, and two, maybe it is just me in a > resource-constrained environment, but 651kb is definitely a big deal, > especially if it brings in other dependencies like google collections. > The fact that Struts 2 is almost 5 megs means it is a no-go for me to > use in our embedded OSGi container.
