Can someone explain to me what java enterprise edition is?? I've been
looking into the web for some info, but can't really make sense of the
info found. Is there also an tutorial avaible?

I've found one at the java site, but there it was attached to an
application server. And that's my second question, what is a
application server and what can u do with it??

Thnx someone.....

J2EE is a standard that defines a set of Java APIs that perform certain
services. The main components are:

- Servlets/JavaServer Pages: These are Web components that dynamically
render HTML and perform some processing.

- Enterprise JavaBeans: These are 'business' components of an application.

- Java Message Service: A way to asynchronously send messages.

There are other components, too. An application server can be thought of
as a implementation of J2EE. All J2EE technically is, is a detailed
specification. Application server vendors implement their own version.
Sun has the Sun Java System Application Server 8, which is the
"reference implementation" - a fully functional implementation created
by Sun. You may also see this referred to as the "J2EE RI".

An application server provides a set of containers that your application
runs in.
