J2EE, Not for Fun?

I was forwarded this video. Very interesting ..

I think it will be more FUN if .Net is included. It probably requires no coding for either examples using Visual Studio Web Developer Express (Free) .. drag and drop, i18n, and preview'able .. anyhow, I am not a .net fan. Oh, and where is PHP. Any commands from PHP'ers.

My current developer side of life is fully occupied by Spring Framework and portlets .... and somehow I have not felt too sad yet!
