The Vaadin Eclipse plugin 1.0 is now on the update site
http://vaadin.com/eclipse . Use the “Check for updates” feature in Eclipse to update to the new version.
New features in the 1.0 release include:
A new project wizard (New → Vaadin Project). The new project wizard makes it even easier to create new Vaadin projects.
Google App Engine support. Create a Google App Engine project and have it up and running in a few clicks. See
Portlet support. Creates all needed portlet configurations for you so the project is ready to deploy instantly.
Additionally there are bug fixes, improved error handling, better progress indication, etc.
We have also updated the Book of Vaadin plugin to 6.1.2 at the same time.
There is a Vaadin plugin for NetBeans
here . It is probably still pretty basic, but I think there are some people in the Vaadin community working on it.
