The web layer of SVLP uses the struts famework ,while Hibernate framework is used on the persistence layer of SVLP.The implementation part of the platform in this paper is mainly on the bussinness subsystem,background management subsystem and security subsystem. The bussinness subsystem contains access&priority control module, buying lottery&encashing on line module and payment module.The background management subsystem includes user management module,bussiness management module and statistic&analysis module,while Single Sign On(SSO) module and digital signature module are contained in security subsystem.
