Dear Friends,
Hi!!I am working on J2ee,actually a newbie to J2ee,Can someone clarify my doubt like can J2EE be used as fullfledged App Server?if yes why go in for TomCat or WebLogic?I do understand J2ee is a Platform with all advanced technologies of Java....But is any company using it as AppServer without any other Servers.
My Company says it is unstable,but I find it great???
Harpal;(

No J2EE is not an App Server, it is just the architecture.
This is a summary of the J2EE Architecture http://developer.java.sun.com/developer/products/j2ee/

To write J2EE application components, an application programmer needs to obtain a J2EE product from a product provider. Product providers are typically operating system, database system, application server, or web server vendors who implement the J2EE platform according to the Java 2 Platform Enterprise Edition Specification.

Actually, J2EE does come with an App Server (run "j2ee -verbose" from the bin directory of your J2EE installation. This is a reference implmentation that comes with a pretty good deployment tool but I don't think I would want to use it for production.

It's probably not stable enough for a real live mission critical application. I certainly wouldn't want to bet the ranch on it. There are enough inexpensive solutions out there that will provide technical support so why use something that wasn't designed for a production environment?
