An understanding of Java J2ee and SOA for dummies

JavaJ2EE and SOA classes are becoming increasingly popular in the current times. Before we understand the basics and differences, let us take a look at what they mean.

Java J2EE: The Java Platform, Enterprise Edition (Java EE) is a collection of Java APIs. This is entirely owned by Oracle. It is a service that software developers can use to write server-side applications. It was formerly known as Java 2 Platform, Enterprise Edition, or J2EE.

SOA: A service-oriented architecture (SOA) is a style of software design. Herein the services are provided to the other components by application components. This is done through a communication protocol over a network. The basic principles of service oriented architecture are independent of vendors, products and technologies.

Amongst the various information technology courses that are shaping up, these are very popular. They are opted by professionals across the domain of software development. They certainly are the light bearers of the future.

A detailed look at both of these courses and their implications

Java J2EE is a widely used computing platform for development and deployment of enterprise software. The platform uses the object-oriented Java programming language.

On the other hand, SOA works on the basic principles of service oriented architecture. Let us understand what a service means in this context. A service is a discrete unit of functionality that can be accessed remotely.This can further be acted upon and updated independently. The process is defined as extremely simple such as retrieving a credit card statement online.

A service has four properties according to one of many definitions of SOA:

  • It logically represents a business activity with a specified outcome.
  • It is self-contained.
  • It is a black box for its consumers.
  • It may consist of other underlying services.

Understanding the application and growing popularity of these courses

These are so popular because of one basic reason: they can be implemented with Web services.This is done to make the functional building-blocks accessible over standard Internet protocols. These are done keeping in mind that they are independent of platforms and programming languages. These services can represent mostly new applications. They can also be used as just wrappers around existing legacy systems to make them network-enabled.

These can help businesses respond more quickly and more cost-effectively. Keeping in mind thechanging market conditions, this is an inevitable benefit. It can also simplify interconnection to—and usage of—existing IT (legacy) assets.

These go a long way in helping organizations to solve problems in a holistic manner. A business has more overall control which is definitely the need of the hour. Theoretically there would not be a mass of developers using whatever tool sets might please them. But rather they would be coding to a standard that is set within the business.

In several contexts these are regarded as an architectural evolution rather than as a revolution.This definitely is one of the biggest compliments.
