What Exactly J2EE is ?
hie all,
I tried studying the J2EE architecture but I have no clue of what it is. This really sound stupid isn't it ?
I did a bit of Java programming long ago using JDK1.4. That was what J2SE isn't it??? I am not sure .
So what is the difference between J2SE and J2EE?
Looks like J2EE have these 3 tier application design (Presentation , business and integration).
So does that mean to comply with J2EE, we need to design out application in 3 different tier/ function?
Please correct me. thank you.

J2EE is an extended version of Java. It includes additional API for "enterprise solutions", whatever that is.
-
what about the 3 tier architecture thingie ???
-
That's optional if you ask me. You can still design your applications any way you want.
-
got it .. thanks ..
so basically its more or less the same !!!
-
Yeah, everything besides the API extension is just marketing babble ;)
-
As far as i understand it the J2EE is just a superset of the standard edition that adds additional features like the Naming and Directory Interface and the JavaMail API bolth of which are available as extensions to the Standard Edition. Im not sure if the JCE(Java Cryptography Extension) is included in the J2EE though.

Oh yeah CornedBee is right. :p Everything about the 3 tier application design is just what he said. The same type of structure can be coded using the Standard API.

hahaha .. Actually i venture quite a bit into J2SE quite some time ago adding new APIs to it getting quite familiar at that time.
Also because I am rather fresh, therefore I don't really know what i know is right. Therefore just try to get clarification from experts.
Cause in my place, people are looking everywhere for J2EE skilled personnels, therefore i start wondering if its something different.
So are you guys with the J2EE architecuturing theory ?? What do you guys think about it ?
Thanks all,

Is J2EE architecuturing the same as Microsofts multiple tier approach? It must be quite similar. :p
