How to use Java based Technologies?
Java is widely used by programmers to
develop various types of software applications like - desktop GUI applications,
websites, web applications, and Android mobile applications. Java is constantly
evolving to simplify and speed up the development of custom applications based
on various business needs. Most of the functional programming concepts such as
unknown functions and lambda expressions which are used widely are supported by
Java 8.
Additionally, Java 9 helps developers
to develop and maintain applications easily by writing modular programs. Also,
a developer has the option of selecting from a wide range of Java-based
technologies, which is based on the type of application and project requirements.
JavaServer Faces (JSF), JavaServer Pages (JSP), and Java Servlets are widely
used by Java programmers. But technologies are different from each other in
terms of their design goals, functionality and usage. So, this article will share
the differences between these Java-based technologies. But, before going to
their difference let’s talk about their brief introduction first.
Ø
JavaServer Faces (JSF)
JSF is a Java-based web framework. This
simplifies web application development by allowing the programmer to create
component-based user interfaces (UI). In addition to providing the standard of
UI components, JSF allows developers to create custom UI components through the
Application Programming Interface (API). Additionally, developers can use JSF
to easily connect reusable UI components with different data sources and
server-side event handlers.
Programmers can take advantage of JSF
to simplify web application development and maintenance using reusable
components. They can also run web infrastructure on Java application servers,
and can present it to UI components according to targeted customers. JSF also
makes it easier for developers to implement custom UI components, to facilitate
data transfer between different UI components and to connect client-side code
to server-side event handlers.
Ø
Java Servlets
Java Servlets are a Java-based
technology that speeds web application development by providing component-based
modules. Developers can extend the Java Servlets as a classroom to expand the
web server and respond to different types of incoming requests. Additionally,
Java programmers can take advantage of various Java APIs and use Servlet to
build custom web applications based on different business needs. They can also
use Servlet to collect user input through web forms, retrieve current records
from different data sources, and generate web pages on the fly.
Many programmers use Java Servlet as a
quick alternative to the Common Gateway Interface (CGI). They also have the
option of creating custom Java Servlet through the packages provided by Java EE
- javax.servlet and javax.servlet.http. Java Servlet makes it easy for
programmers to accomplish many web development tasks - reading implicit HTTP
requests or reading explicit data sent by web browsers, sending explicit data
to a web browser, sending built-in HTTP responses to customers, and generating
results by processing data.
Ø
JavaServer Pages (JSP)
JSP is a Java-based server-side
programming that helps developers in creating web applications that support
dynamic content. By using JSP, developers can reach a wide range of Java APIs
according to precise project requirements.
They can also use the JSP tags without
writing additional code to insert the Java code in HTML pages. JSP components
work just like the user interface for Java applications. Programmer has the
option to write JSP as text files, and easily integrates text files with HTML,
XML and XHTML code.
While writing web applications in Java,
programmers can use JSP as a strong alternative to the Common Gateway Interface
(CGI). But developers can use JSP tags to accomplish common web development
tasks using JSP tags. They can also use JSP as dynamic elements in HTML, to
create dynamic web pages and to collect user input through web form. JSP enables
developers to take advantage of a wide range of Enterprise Java APIs by
borrowing Java Servlet API.
Comparison between these three Java
technologies:-
JSF enables JSP and Servlet developers
to write different types of web applications fast and efficient in Java. But
they can use JSF as a web framework to simplify the development of large and
complex web application development by implementing the Model-View-Controller
(MVC) programming paradigm. On the other hand, JSP can be used as a server-side
technique to speed up general web development tasks through tags and accelerate
template development with client-side technologies.
Additionally, the Java Servlet can be
used as a pre-compiled Java program to simplify the development of web
applications on the fly with dynamic content. Java programmers have the option
of using JSP and Servlets each interchangebly while developing Web applications
on the basis of MVC patterns. The servlet is much faster than JSP. But JSP,
unlike the Servlet, allows Java developers to complete normal web development
tasks without writing additional code. In addition, JSP acts as a visual in
MVC, while Servlet acts as the controller in MVC. When web applications require
large amounts of data to be processed or used efficiently, it is always
advisable to use Servlets instead of JSP.
Conclusion:-
As a result, developers can take
advantage of JSP, JSF and Servlet facilities to build custom web applications
fast based on various business needs. They should understand that Java-based
technologies differ from each other in terms of design, functionality and
usage. Therefore, while comparing JSF, JSP and Servlet, the types and
requirements of individual web applications should be kept in mind.
