You have probably seen it already, but I sent a note about your OSGI articles (nice stuff!) to our Aquarium blog and Vaadin was featured in one of the entries. If you haven’t heard of it before, “The Aquarium” is among the top-read blogs at Sun:
I’m working on a blog or two for our upcoming GlassFish v3 release (Java EE 6 implementation) and may have a few questions on Vaadin best practices with Java EE since I would like to use Vaadin as the application UI. If there’s a document already about it, a pointer would be great, but otherwise I can summarize my own thinking and you can tell me where I’m wrong.
Yes we did. Thanks - quite a few visitors came through your blog post to vaadin.com.
Please post any questions you have on this forum - I am sure that there are quite a few people who have experience with GlassFish V3 + Vaadin + OSGi combination and would like to help out.
