How to develop a high quality J2EE system

[Abigail101]

Hi all,

I am a core java developer, Now i have a build the J2EE system over the web server. I know that java 2 enterprise edition is work as a middleware. Just i want to know that how to develop high quality J2EE system over the web. Please suggest. Thanks in advance.

Java and J2EE are two different concepts, Java is not just refer to a language, has been different with Microsoft on behalf of another great camp, so Java is sometimes refers to a software system for schools, of course, are mainly. NET and the two main system for Java. J2EE can be said to refer to Java in the database information systems implementation, database information systems from the early dBase, into Delphi / VB, etc. C / S structure, and developed to the B / S (Browser Browser / Server server) structure, which mainly refers to the J2EE B / S structure of implementation. thanks and reply.

J2EE is a framework and standards, frameworks similar to the API, the library concept, but to exceed them. If you need to learn more about the framework can begin with design patterns begin to study. J2EE is a virtual concept of large, J2EE standards there are three main technical standards for the seeds: WEB technology, EJB technology, and JMS, it should be said about J2EE ultimately implemented in these three sub-concepts. Best of luck.

J2EE application development tools, there are many: such as JBuilder, Eclipse, etc., these IDE first Java development tool, that is, they are the first basic function is to develop JavaBeans or Java class, but if you want to develop a J2EE system, it is necessary to implement to either the Web technology or EJB technology, then there may be a number of specialized modules features, the most important, because the J2EE container and the application of the system is divided into two parts, so that in any development tool Developer J2EE need to specify the J2EE container.

J2EE framework of the standard will be a WEB and EJB system is divided into the main part, of course, From an abstract design for the presentation layer, service layer and persistence layer , the three levels from a height will be separated from J2EE to achieve the purpose of decoupling. With J2EE specific technologies to achieve this time, you can use the EJB specification for service layer and persistence layer, Web technology to achieve the performance of layer. Best of luck.

to develop a high-quality J2EE system also needs a correct understanding of business needs, then the domain modeling provides a more practical understanding of business needs the right approach, detailed knowledge of the relevant point of view can be read in conjunction from the UML . If you want to design your own industry framework, then let us begin with the first step from the design pattern, as design patterns provide you with an implementation of JavaBeans or similar decoupling between the reference implementation method. Best of luck.
