A
developer needs to understand several widely used technologies to
build large-scale and robust enterprise applications. But many
programmers prefer Java programming environment to build
comprehensive business solutions by availing a number of advantages.
As Java is platform independent, it allows developers to develop
global enterprise solutions and web services to target major
operating systems and computing devices. At the same time, some of
the original limitations of the technology can be overcome by using
inexpensive mass storage devices and faster processors
.
The
performance of an enterprise application depends on a number of
factors. Along with use of multiple threads and object serialization,
the system also needs be deployed in a proper way. A programmer can
meet all these requirements by using Java to develop business
applications. The Java Run-time Environment (JRE) is designed as a
specialized version of Java classes and interpreter to make the
application deployment process hassle-free. The JRE does not include
any tool required to develop applications. But it includes the
classes required to deploy the enterprise applications.
Most
developers also use Java plug-in to boost the performance of their
interfaces without putting any extra effort. As a web browser
extension, the plug-in works seamlessly with major web browsers.
Further, the end users can simply install the plug-in to run a
variety of Java applets to meet their individual requirements. A
programmer can use the plug-in to release customized applets that can
be used by the end-users without updating or changing their web
browsers.
The
required amount of security and reliability often make enterprise
application development complex. Most organizations also opt for
multi-tiered applications to segregate their functionalities into
tiers or isolated functional areas. The Java EE platform has made
enterprise application development less complex by offering an API,
development model and runtime environment. The runtime environment
also makes it easier for programmers to concentrate on the
functionality and performance of their enterprise systems.
Using
Java for Multi-Tier Enterprise Application Development
Client
Tier: The client tier of the application consists of clients
that are located on machines different from the server. The clients
access the Java EE server, and send requests to the server for
processing. The server processes the requests, and returns back
responses to client. Based on the requirements of your project, you
can use a variety of applications as Java EE clients. Some of these
applications can also be developed using other programming languages.
At the same time, the clients can be a standalone interface, a web
browser or any other server. But the clients must run on a machine
that is different from the Java EE server.
Web
Tier: The web tier of a business system includes components that
handle the interaction between business tier and clients. Along with
generating dynamic content for the client, and controlling the flow
of pages or screen, the web tier further maintains data for the
session state of the client. Also, the tier is used to collect input
from users, and return appropriate content or results from the
business tier components. A programmer has options to use variety of
Java EE technologies to build the web tier of a business system,
including JavaServer Pages (JSP), JavaServer Pages Standard Tag
Library, JavaServer Faces technology, JavaServer Faces Facelets
technology, Servlets, JavaBeans Components and Expression Language.
Business
Tier: The business logic for an enterprise solution is supported
by the components included in the business tier. Normally, the
business logic can be defined as the code that adds functionality to
a specific business domain. While developing enterprise applications,
the programmers ensure that the core functionalities exist in the
business tier components. A developer also has option to use a
variety of Java EE technologies in the business tier of the
application including Enterprise JavaBeans, JAX-WS web service
endpoints, Java Persistence API entities, JAX-RS RESTful web
services, and Java EE managed beans.
Enterprise
Information Tier: The enterprise information tier of a business
system consists of enterprise resource planning (ERP) systems,
database servers, and legacy data sources like mainframes. Normally,
these resources are located on a machine different from the Java EE
server. The components of enterprise information tier are frequently
accessed by the business tier components. A programmer can use
several Java EE technologies to store, modify, access and manage the
business data in a simpler and hassle-free way.
Many
reports have highlighted the advantages of Java over other
programming language for custom-developed enterprise application
development projects. The upcoming release of Java 8 will further
help developers to enhance the performance of their applications by
availing a set of advanced and fresh features. Certified
java programmers
can help you build projects within allocated budgets and time
schedules.
