Distributed objects and World Wide Web are playing a more and more important role in the construction of enterprise distributed computing environment because the former can be used to wrap business logic and accessed through heterogeneous platforms,and the latter offer powerful abilities in the information integration and interaction with end user. The J2EE application based on web need to restrict the access to important information,provide various access rights to various users and protect the security of transmission of sensitive information. JAAS technique is a good solution.This paper introduces the architecture of the application,Java security model,J2EE security model and JAAS architecture,then make the Login Module design applying JAAS based on J2EE.This paper is based on the project "Nanjing YueJin Mobile Corp Parts Factory MIS updated" .
