									J2EE
Java 2 Platform, Enterprise Edition is a platform designed for mainframe-
scale in order to compute distinctive large endeavor. Sun Microsystems
putting his hands together with its industry partner IBM jointly
deliberated J2EE in order to make the application development simpler and
easier in an emaciated client tiered environment. J2EE abridges
development of the application and it minimizes the requirement for
programming and programmer guidance by generating consistent, reusable
modular components and also by facilitating the tier to hold many aspects
of programming instinctively. The J2EE platform holds a few services like
APIs and Protocols. This will provide the functionality to develop a
multitiered Web Based application.
In the term J2EE, 2 in the abbreviation J2EE denotes for Version 2. J2EE
is a Java Platform Version 2. Now-a-days the number 2 has been ignored
and so J2EE has now become as Java EE. Here EE stands for Enterprise
Edition which is the most prevailing form of Java platform. J2EE improves
J2SE with the following features. They are XML, Java Server Pages, Java
Servlets API and JavaBeans. J2EE is a platform which is mainly used for
developing a multi-tired architecture programming application depending
on components executing on an application server.
J2EE comprises numerous mechanism of the Java 2 Platform, Standard
Edition and they are as follows.
• The JDK which is known as Java Development Kit is integrated as the
central part of language package.
• In order to ensure and enrich portability a technology called Write
Once and Run Anywhere is incorporated here.
• A prop up is granted for CORBA, it is nothing but a Common Object
Request Broker Architecture, a precursor of EJB, and it is nothing just
an Enterprise JavaBeans. The Java objects can converse with Common Object
Request Broker Architecture objects both locally and also over a network
with the help of its interface broker.
• Java Database Connectivity 2.0, the Java equivalent to Open Database
Connectivity is included as the standard and customary interface for Java
databases.
• In both local and Web-based applications a security model is
implemented to safe guard data.
J2EE also includes quite a large number of components in addition to the
J2SE model. They are as followed:
• Maximum support is granted for EJB (Enterprise JavaBeans). EJB is a
server-based technology which is used to deliver program components in an
enterprise environment. It gives a good support to XML. XML is nothing
but the Extensible Markup Language, it has improved consumption and
safety features.
• The Java servlet Application Programming Interface increases and boost
ups the reliability for the program developers without involving a
Graphical User Interface
• A Java Server Page is the same as the Active Server Pages which are
ultimately used for creating and manipulating dynamic Web-enabled data
access.
