Click here to start learning about the NetBeans APIs (but don't forget the best source of all... NetBeans API Javadoc):
(Of course, the trail is incomplete, many more tutorials need to be added and will be added in due course.)
But, if you're interested in any of the other areas of NetBeans, well they have their own learning trails too:
(More learning trails are being planned for other areas and packs, so watch this space!)
Though each of the learning trails come from a different area of NetBeans, involving different writers and engineers, we have tried to maintain a consistent look-and-feel and general user experience. Feedback on these trails is very welcome (and very needed). So, if you've looked at one or more of the trails, and have something to say (whether good, bad, or neutral), feel free to share it by going to the feedback form via this link:
Thanks and... happy trails!
In other news. Roumen just drew my attention to Alex Kotchnev's work on... a Tapestry module for NetBeans! Looking great, Alex, even though it was from a month ago (I wonder if you've made progress since then). Click here to check it out!
