I’ve mentionned NetBeans as an RCP Platform before.
The NetBeans team is making good progress:
– Better support in NetBeans IDE (Wizards) showing up current NetBeans builds (via Geertjan)
– Draft documentation that goes with it
…and I hear JavaOne 05 will also have a hands-on lab on building NetBeans modules.
The NetBeans Day (free day prior to JavaOne) should demonstrate this also.
