java ee 5 & java ee 6 market demand

Hi All,

We have Java EE 6 for almost an year or so, I have following questions about it:

1) Java EE 6 has many version upgrades with respect to EJB, Servlets and JSP. If i learn Java EE 6 now will the case happen where in a company can that we are using Java EE 5 so we dont need you?
2) What is the market demand of Java EE 6 compared to Java EE 5? ( I mean which should i learn? )
3) I have also heard from many that Java EE has been replaced by the Trio Struts, Springs and Hibernate, So is it better to learn the Trio than Java EE?

Kindly excuse me if my questions are stupid i am a real noob on these.

Regards,
Vivek.

JEE 6 is pretty light weight and has learnt from some of its mistakes. The Sprint + Hibernate combo is used as an alternative by some shops, but other are happy using JEE6.

we are using Java EE 5 so we dont need you

A good company will acquire you for your skills to learn and not the frameworks you know to use. Why does it matter that the company uses framework 1.x and you know version 2.x ?

What is the market demand of Java EE 6 compared to Java EE 5?

I know a couple of projects that use JEE6 and some that use Spring. There are many that still use JEE5. You can learn what your project needs and adapt accordingly.

Thanks a lot Deepak Bala
