J2ee Applications, Human Resources Management System In The Coal Industry

With the continuous improvement of computer hardware performance, and prices declining, its applications are constantly expanding. More and more people in the area hope to more and more difficult to transfer the problem to the computer to resolve. This makes computer software, the increasing size and complexity, so the software technology continues to face new challenges. J2EE (Java 2 Platform Enterprise Edition J2EE) is a development of distributed enterprise-class application development technical architecture, the current through the test of practice, that can rely on J2EE technology is an enterprise-class software development technologies, by many large IT industry vendor support,Has very broad prospects. It uses Java 2 platform enterprise solutions to simplify the development, deployment and management of complex issues related to architecture, which defines a typical four-layer structure, namely the client tier, Web tier, business logic layer and the enterprise information system layer. To build a multi-tier architecture for scalability, flexibility, easy maintenance of business system provides a good mechanism.This article first J2EE architecture are briefly introduced, and then combining the actual situation of the mine personnel management system analysis and modeling, in the actual development process, chose to use the current popular J2EE framework for Struts carried out the project's preliminary development and realization of the project's basic functionality and general framework. Struts for Web application provides a common framework, enabling developers to concentrate on how to solve real business issues. In addition, Struts framework provides a number of places available for expansion and customization, enabling the application can easily be extended framework,To better adapt to the user's actual demand.
