Hi ,
I have used j2ee 1.4 technologies in weblogic 8 server and they are doing fine.
Now recently I saw Oracle-Sun providing j2eesdk1.4 for download what is the use of that?
I believe all the j2ee1.4 api is already included in weblogic.jar file.

how am I going to get benefitted by using this j2eesdk1.4 ?

Thanks all.

All versions of J2EE are obsolete, including the latest, 1.4. If you're starting a new project, consider using JEE 5 or JEE 6 instead.

These are also included in the weblogic 10 server. My question is why is the JEE5 sdk or JEE6 sdk provided by sun. What we do with that? we all get the apis in the servers itself.
I believe a developer can develop applications based on JEE6 without the JEE6SDK

If you are using some application server which has support for Java EE then you don't have to download the SDK from Sun/Oracle. Sun/Oracle themselves provide a reference implementation (RI) application server which is included in that SDK.

The SDK may have sample code or documentation that does not come with the server, though.

Do we use this sdk in real time application development anytime?

Real-time computing isn't a feature of JEE. Oracle provides a special JVM that is suitable for real-time applications, but that is a commercial product that is separate form the JSE/JEE reference implementations.
