How To Solve Performance Problems In Java Enterprise Application Development

The discussion about java performance has never been stopped since java was born. But a lot of progress has also been made with java, which entered enterprise application domain from internet and has become one of the major tools to develop enterprise application. It has also entered Chinese enterprise for a rather short time, and most developers here are not well equipped with java. So there is a high urgency for a comprehensive and correct understanding of java enterprise application development.The development of java enterprise application for performance targets at producing application that reaches the performance goals in a given time. But how to achieve this target?There are a lot of articles both at home and abroad which study this issue, and which provide two major views. The first one regards performance development technology as the major cause of the performance problems in java enterprise application. The other one takes performance development process as the major cause. These two views lead to two different solutions. One is technology solution which depends more on the design and implementation of high performance, and the other one is process solution which depends more on well-organized performance development process. But both solutions have their own defects.In order to remove the defects of the two solutions and to help the developer successfully solve the performance problems in java enterprise application, this paper puts forward a new and different solution, which includes rethinking about performance development technology, comprehensively understand performance development process, and combining both in the development process. This solution has practical significance.This paper is divided into five chapters.Chapter one serves as an introduction of the background of this paper, and puts forward the performance problems in java enterprise application.Chapter two first lists the general performance problems in java enterprise application, and their causes. Then it studies the present solutions and their defects. Chapter three first explains my own solution, then discusses in detail about performance development technology and process, and at last shows how to combine both in the development process.Chapter four uses a J2EE website as an example to demonstrate how to apply the new solution into practice.Chapter five concludes the major points of this paper.
