Why JavaEE5 is not used.

Came across this good article in javalobby. There is a developer from france who has written about why the world has still not embraced the JavaEE5 release which is going to be 2 years old in a few more months. Even though JavaEE5 is way much more better than its previous release J2EE1.4, the factors affecting its adoption are basically the learning curve involved, ignorance to the improvements made and lack of popular j2ee container support to it. Even though glassfish is fully JavaEE compliant and one of the best JavaEE containers to use, people seem to still associate it with older releases and are hesitant to go use it.

Also, people have the thought that EJB3 is still the old EJB. Lots of empty methods, home and remote interfaces, tons of xml configuration etc.. Despite a lot more improvements made in EJB3 which have made it much less confusing and easier to use, people are still not investing in it.

The move to JavaEE5 also requires the adoption of jdk1.5 from 1.4 which companies are not investing in again. (somehow that sounds stupid to me.. But i dont work in those companies)
