| With the increasing enterprise demands and rapid development of network technology,enterprise application development is becoming more and more cautious and complex.Adopting reasonable enterprise applied framework and new technology will be significant to whether enterprises can use their own information resources effectively for favorable status in the competition.With the recent development of science and technology,enterprise distributed technology has become more mature,in particular,it has been proved successful by n-tier B/S architecture and J2EE technology proposed by Sun Microsystems Inc that have been applied in the constructions of more and more enterprises.J2EE is a n-tier distributed architecture,each of whose tiers involves different technology.But on how to reduce the coupling between the tiers and improve the flexibility,haleness and extensibility of the information system,it doesn't propose a concrete solution. Therefore,the author puts forward one large-scale Web application deployment framework and implementes the core module with the help of practical project experience and the design patterns of the software engineering which the paper puts emphasis on. This framework provides one reference to the rational deployment of Web application and carries on the secondary development with it.As the important part of the deployment framework,the database connection pool can be used independently too,so this paper set up one chapter and proposed a database connection pool with its own characteristic specially.The information system construction of a certain port bureau adopted B/S Architecture based on J2EE platform,which offers a chance for the practical application of deployment framework which the paper puts forward. The first stage of the project development has finished and come into operation already now. The satisfaction of the users, development efficiency and systematic operation conditions verify the validities of the deployment framework. |
