In today’s fast changing world, we have to change from time to time in order to be more efficient and updated. Before J2EE, the software developers had to spend a lot of time on the application transaction programming, resource pooling, threading, security and product life-cycle management. Yet, they were uncertain whether their application would be able to run smoothly on another system or not. With J2EE, what will happen? Will the situation be improved?
We will evaluate this latest application from 3 key areas. The following questions determine whether you should choose J2EE?
• Can this application help to integrate your network?
All J2EE-compatible services and applications are able to interoperate across the networks at fast pace. They provide integration of existing disparate systems and interoperability across the networks in an effective manner. For instance, the users can integrate component-based Java technology programs with Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) systems easily.
• Are all J2EE products compatible with other software?
It is proven that all the products have passed the J2EE Compatibility Test Suite. More than 15000 software tests were conducted to ensure that the products are able to meet the “Write Once, Run Anywhere” standard. In other words, an application that runs on a J2EE compatible server will be able to run a full range of other vendors’ servers without facing problems. As a result, the users have a wide range of compatible products to choose from many vendors due to the open standards offered by J2EE.
• Does J2EE provide you a good programming model?
It provides you with a programming model that uses Servlets, JavaServer Pages and Enterprise JavaBeans. The model is used to implement and deploy business logic. Each of these component technologies offers different frameworks to the users so that they can implement and deploy business logic based on different situations. For instance, Servlets provides platform-independent and server-independent Web-based applications which enable the users to work out the best for their servers, platforms and tools. On the other hand, JavaServer Pages technology provides the software developers with a simple way to distribute application functionality to a wide range of page authors.
In short, we can say that J2EE brings a lot of advantages to the users. In the point of view of the IT specialists, J2EE is considered an end-to-end solution. It not only provides technology specifications, but also offers reference implementation. It is portable and powerful. It is suitable for people who are looking for excellent way to deliver Web services. However, please bear in mind this point. Moving to a Java-based server solution can be an ideal decision if you are able to choose the right J2EE server for yourself. There are many areas you need to consider before choosing a J2EE server, such as the cost, scalability, standard compliance, support, and so on. If you make the wrong decision, you will be suffering more system downtime which you or your organization may not be able to afford. Hence, you are reminded to make careful selection.
