Effective Web Service Development Using RESTEasy

RESTEasy is a member of the JBoss family which provides different frameworks to help build RESTful Web services and enriches Java application development service. It is in-built in JBoss 6 onwards. It denotes a completely certified and portable implementation of the JAX-RS framework, which is a new JCP (Java community process) specification which gives a Java API for RESTful Web Services over the HTTP protocol. REST is an abbreviated form of REpresentational State Transfer.

RESTEasy is a versatile Java framework especially intended to assist users build RESTful Web services. RESTEasy has a portable implementation that can run in any servlet container, but tighter integration with the JBoss application server is also obtainable to make the user familiarity better in that environment. JAX-RS contains only server-side specification, whereas RESTEasy get the JAX-RS functions to the client side through the RESTEasy JAX-RS Client Framework. This lets the HTTP requests be mapped to the remote servers with JAX_RS and interface proxies.

It focuses on easy servlets primarily configured with annotations (even web.xml can be omitted when using J2EE). RESTEasy comes with some simplistic features to create Rest web services. Also support for JAXB and JSON is available. By adding some simple tweaks in your objects to serialize to XML or JSON, Rest services can be developed.

Salient Features of:

  • Globally accessible resources
  • Understandable resources, actions and URIs
  • Platform independent, can be used with any application server
  • Lightweight and possesses a rich set of providers for XML, JSON, YAML etc.
  • Integrates easily with Enterprise JavaBeans (EJB), Spring and Spring MCV Framework
  • Easier component integration
  • Can be used with any protocol
  • Enriched interceptor model
  • Asynchronous HTTP (Comet) abstractions for JBoss Web, Tomcat 6, and Servlet 3.0

The Endless Debate: Cross Platform or Native Applications?

Native application is an application program that has been developed for use on a particular operating. It is device and platform dependent.  A Cross platform app like HTML 5 app is housed on the web and runs inside a device browser, in contrast to device specific apps. The developers do not build the applications for each Operating System.

So we have the endless debate. What is better?

To attempt deciding this, let us discuss some of the important factors that will impact application development, user experience & mobile applications development.

Native Applications:

• Better User Experience & Performance
Since native apps are developed for a specific platform, they can easily interact with various features of the operating system and get advantages of special functionalities, these  are not still achievable using Cross platform

• Faster Graphics & Fluid Animations

Graphics are faster, plain and simple in native apps as it directly communicates using frameworks, which are specially, designed for specific platforms. It might not be so important if we are dealing with simple apps but it is especially important in games, apps that are very interactive and manipulate images and sounds.

• Security
Along with performance, security is one of the reasons of using native app over Cross platform HTML 5 apps. Native application are more secure due to use of native framework and APIs.

Cross Platform Applications using HTML 5

• Easy to develop
It is easy to develop applications using HTML 5 and most of the developers like to write code using HTML.

• Cross platform deployment cost
Cross platform apps are developed only once. It is common for all platforms and hence the cost of redevelopment for each operating system is avoided.

• Performance
HTML 5 is known to be the common language of the web, It works seamlessly across mobile platforms and browsers. They can be installed from the web as icons on home screens across any phone with the same performance and user experience.

• Searchable contents

The contents on HTML 5 can be crawled and indexed by search engines, so possibly discovered by people searching on the net. This increases the accessibility of the app tremendously.

All said and done, Native Apps & HTML 5 Mobile Apps both are acceptable based on functionality of applications, if there are some limited functionality in applications then HTML 5 is the best choice, but when dealing with some complicated domain functionality & the best user experience & performance are the targets then Native Apps are the best choice.

It is an endless debate…
