Last month I recorded two enterprise messaging videos at O'Reilly's campus in Sebastopol, CA, and I am happy to say that they were just released today! You will have to excuse the shameless plug in a blog, but I am very excited about these videos because it was finally a chance to unload 12 years of JMS and Spring messaging knowledge and make it available in video form. All of the chapters in these videos have live coding (with the exception of the messaging design chapter).
You can find the videos on the O'Reilly website or on Safari Books Online. Happy viewing!
