Java
is a very well-liked and extensively used programming language for developing
applications starting from mobile applications to enterprise servers and
computers. The language was developed keeping the plan of giving a cross
platform environment for software applications. At the moment, Java is present ubiquitously
from mobile phones to web systems, from enterprise applications to desktop
computers etc. Java applets are utilized in desktops to offer improved browsing
experience to users.
If
we discuss about J2EE or the Java to Enterprise Edition platform developed by
Sun Microsystems which decides the standard for developing multi-tier
enterprise applications. It is broadly used by top IT firms to design and
develop applications.
There are a range of elements that combine together to
enable development, which are as follows:
·
Compilers are accountable for
converting source code into Java by code
·
Loaders infers the Java class files into a
readable format
·
JAR is an assembly of related class libraries.
·
Java.doc is used as the documentation generator
·
JDB is used for documentation
The
language has been intended to simplify the process of development of
applications that make enterprise services available readily to customers. The
J2EE application model evidently defines architecture for completing services
such as multi-tier applications that distribute the scalability, accessibility
and manageability necessary by enterprise-level applications. The application
can be separated into following tiers: client tier, middle tier and data tier.
The
Client Tier consists of an application like a Web browser, stand-alone
application, or any other servers running on a different machine from the Java
EE server, which then makes a request to it. With this architecture it receives
the request, processes it and then sends back the response to the application.
The
Middle Tier contains business functions that hold client requests and hence
processes application data. It provides business logic and provides
functionality to a particular business domain, like financial industry,
e-commerce which contains the core functionality of process.
The
Data Tier is also known as enterprise information systems which basically
consist of an enterprise resource planning systems, legacy systems and database
servers. These data resources are typically stored in a system separate from
the Java EE server.
The main benefits of software
development using java are:
• The Language supports multi-platform
language and web-services too
• Java can be used to develop dynamic web applications such as e-commerce, e learning, polls, HTML forms processing and more
• J2EE combines Java technology-based applications or services to create highly customized applications or services
• Java supports to write powerful and efficient mobile application development content
• Java can be used to develop dynamic web applications such as e-commerce, e learning, polls, HTML forms processing and more
• J2EE combines Java technology-based applications or services to create highly customized applications or services
• Java supports to write powerful and efficient mobile application development content
J2EE
permits developers to develop great, reliable, scalable and secured
applications known as enterprise applications. These applications are consumed
by huge corporations to overcome their IT challenges.
