Discussion And Reality About The Security Of Process Of Manufacturing Enterprise Information System Based On J2EE

The act of converting in management that contemporary Process of Manufacturing Enterprises need more opening operation and more rapid response ability is Stimulating PMEIS to develop towards the distributed system in architecture and component system in methodology As a result, distributed component system is becoming the mainstream platform on to build the enterprise information System.In the background, In order to secure the information resources of PMEIS, in this paper, the security issues of distributed system and the latest development of application server are traced, the security mechanism of distributed component system based on J2EE is studied, the security issues brought by the programming model of distributed component system are enumerated, This paper gives a solution to these problems that the authentication and authorization mechanisms can be added to the programming model and provided as the run-time services of the component system.This paper provides the implement progress to the solution under the J2EE environment Java RMI is extended by adding the authentication and authorization mechanisms secure access for EJB component is implemented in the J2EE environment Based on that, a secure P-SCM management information system is developed.To solute the security issues of distributed PMEIS. The research can provide a reference and can bring some significance in theory...
