what IDE do you use
Me? That's Eclipse for Java EE. There are alternatives, like Netbeans and IntelliJ IDEA.
and where can I learn to work with Java EE platform ?
Start with the Sun Java EE tutorial.
Good luck.
Seriously, if you're actually interested to learn the Java EE Web Profile, then I recommend to read the following questions/answers:
That's a very wide question. I would recommend to take a look at Eclipse (dowload the Java EE version) and Netbeans for IDEs. And at Sun's Java EE Tutorials to get started with Java EE. Good luck!
Any of the Big Three IDEs (Eclipse, IntelliJ and Netbeans) are fine. Personally I use IntelliJ.
You probably don't need to do any JEE beyond having a Web container like Tomcat or Jetty and using Spring plus possibly JPA (eg Hibernate, EclipseLink). There are a plethora of Java Web frameworks that you can put on top of that (eg Struts 2, Wicket, Tapestry, JSF).
The advantage of Java EE is that you can plug pretty much any pieces you want to together (typically using Spring as the glue). The disadvantage is that that is so flexible there isn't really an obvious starting point.
I use Netbeans and you can find pretty good tutorial material at the Sun Java EE tutorials page.
There's also a commercial (i.e., not free) version of Eclipse called MyEclipse, which offers a lot of nifty features. Worth consideration.
