Before you continue you should have a basic understanding of the following:

WWW, HTML, XML and the basics of building Web pages Scripting languages like JavaScript or VBScript The basics of server side scripting like ASP or PHP

If you want to study these subjects first, find the tutorials on ourHome Page

What is Classic ASP?

Microsoft's previous server side scripting technology ASP (Active Server Pages) is now often calledclassic ASP.

ASP 3.0 was the last version of classic ASP.

To learn more about classic ASP, you can study ourASP tutorial.

ASP.NET is NOT ASP

ASP.NET is the next generation ASP, but it's not an upgraded version of ASP.

ASP.NET is an entirely new technology for server-side scripting. It was written from the ground upand is not backward compatible with classic ASP.

You can read more about the differences between ASP and ASP.NET in the next chapter of thistutorial.

ASP.NET is the major part of the Microsoft's .NET Framework.

What is ASP.NET?

How Does ASP.NET Work?

When a browser requests an HTML file, the server returns the file When a browser requests an ASP.NET file, IIS passes the request to the ASP.NET engine

on the server

The ASP.NET engine reads the file, line by line, and executes the scripts in the file

Finally, the ASP.NET file is returned to the browser as plain HTML

What is ASP+?

ASP+ is the same as ASP.NET.

ASP+ is just an early name used by Microsoft when they developed ASP.NET.

The Microsoft .NET Framework

The .NET Framework is the infrastructure for the Microsoft .NET platform.

The .NET Framework is an environment for building, deploying, and running Web applications andWeb Services.

Microsoft's first server technology ASP (Active Server Pages), was a powerful and flexible"programming language". But it was too code oriented. It was not an application framework andnot an enterprise development tool.

The Microsoft .NET Framework was developed to solve this problem.

.NET Frameworks keywords:

Easier and quicker programming Reduced amount of code Declarative programming model Richer server control hierarchy with events Larger class library Better support for development tools

The .NET Framework consists of 3 main parts:

Programming languages:

C# (Pronounced C sharp) Visual Basic (VB .NET) J# (Pronounced J sharp)

Server technologies and client technologies:

ASP .NET (Active Server Pages) Windows Forms (Windows desktop solutions) Compact Framework (PDA / Mobile solutions)

Development environments:

What is j2ee

"Java" refers to both a language and a platform. The runtime and libraries that comprise the

platform are based on the Java language and come in 3 flavors:

Java SE (Standard Edition): Formerly J2SE but renamed to Java Standard Edition when the Java 2

convention was dropped with the release of Java 5 (formerly J2SE 1.5). It contains a good all-

around mix of general purpose libraries including JDBC (Java Database Connectivity), JNDI (Java

Naming Directory Interface), RMI (Remove Method Invocation), AWT, and Swing.

Java EE (Enterprise Edition): Formerly J2EE (see above). It includes Java Standard Edition plus

most of the other Java technologies including JavaMail, Activation, JAXB (Java API for XML

Binding), Servlets, JSF (Java Server Faces), JMS (Java Messaging Service), EJB (Enterprise Java

Beans), and others. Most of the APIs are very component-oriented and are intended to provide

pluggable interfaces for business components to form robust, distributed internet applications.

Java ME (Micro Edition): Formerly J2ME. It includes most of Java SE and some additional APIs for

handheld devices.

Java Enterprise Edition is based on Java, but includes a larger set of libraries than Java Standard

Edition, which to most people is synonymous with the word "Java." Note that many of the

technologies featured in Java Enterprise Edition are available separately and can be added to the

Java Standard Edition platform as needed.

Answer

Hi! Java is a language and j2ee is a plateform which implements java language.

AnswerJava can be divided into 3 categories

1.core java

2.advanced java

3.J2EE

core java and advanced java are the standard editions of java where as J2EE is the enterprise

edition

without completing core and advanced java u will not be able to understand J2EE
