Application servers, i.e. Weblogic, tailor the J2EE spec to their specific implementation. Then they get their App server certified by Sun (which by the way is hugely expensive and is where Sun make money for Java being free
So, you cannot just download J2EE from Sun and run a servlet. You download J2EE and use it to write and compile your servlet, then deploy it to your servlet container (Tomcat) or App server (Weblogic).
Start with J2EE.

Very recently, I started testing my simple ejb's with J2EE. Now after approx. 10 days or so, I have graduated to weblogic 6.1. I think it's more of a baby step procedure to learn..'First try with a small thing (J2EE), get familier with the environment, feel yourself at home. When things become a bit cool, try to jump to the weblogic band wagon.
Thanks & Bye,

For above answer I have some more doubts please clarify them.
I am confused ...
Here I am deploying my beans in to J2EE server can't I do that for servelet and JSP and one more thing is when J2EE is compiling can't it run the jsp or servlets
Thanking you in advance

You don't need J2EE to compile your servlets , just a single 'servlet.jar' file along with the JDK1.2.x or JDK1.3.x will do it. You need a container/server to do the deployment part, like apache+tomcat or the weblogic server. Secondly, you can use J2EE for running all - ejb, servlets and jsp files. It's all in all complete.
