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.
o The JDK which is known as Java Development Kit is
integrated as the central part of language package.
o In order to ensure and enrich portability a technology
called Write Once and Run Anywhere is incorporated
here.
o 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.
o Java Database Connectivity 2.0, the Java equivalent to
Open Database Connectivity is included as the standard
and customary interface for Java databases.
o 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:
o 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.
o The Java servlet Application Programming Interface
increases and boost ups the reliability for the program
developers without involving a Graphical User Interface
o 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.
