Research On The Sharing Supports Platform Which Is Based On The J2EE And Pluggable Component

With the Internet's gradually penetration,the construction of e-government obtains the widespread value and advancement around the world,and changes profoundly in the government tradition organizational structure and the management service pattern,thus speeds up the national economy and the social informationization advancement,impels the economic society,to coordinate the sustainable development comprehensively,all these are the new challenge to the construction of e-government,however,at present,the status of e-government: e-government coordination,unable to link,information isolation appeared,a number of e-government can not be integrated with the provision of services,so to achieve scalability,integration capabilities,and loosely coupled platform into a solution on the above-mentioned problem.The dissertation first analyses distributed system of C/S and B/S,compare the B/S with C/S,the former possess more advantages,then,explain the three-tier(or multi-tier) web application architecture,Second,briefly describe and analyses the MVC design pattern,as well as the realizable framework(Struts),then,present the most popular platform of J2EE through multi-faceted analysis,followed by introduction of the component technology in reusable software and XML technology,finally,adopting component technology and J2EE's multi-tier architecture,and the integrated development environment of Eclipse+Tomcat+Weblogic+Oracle,combining Struts framework,designs and complete the sharing supports platform.The sharing supports platform is the subsystem of the sharing platform of information,which provide supports to other systems,throughout the design of sharing platform of information,different levels of application integration has been taken into account,which contain data layer,application layer and business layer. Different layers have different methods and techniques.The integration in data layer need to support the integrating capabilities of databases,files,EMAIL,and XML,the access in two way,the real-time synchronization,the data mapping,the correlation and the ability to bring together,in order to meet the needs of data integration and data sharing,application layer need to support the different application systems,the underlying middleware platforms,including J2EE,COM,CORBA etc,also need to adapt to the different languages of development,such as C/C++,Java,BACIS etc, the integration in business layer need to base on the support of Integration in data and application layer,realize the real-time management of business process,and industry standards,in order to meet the regulatory mechanism,which is concentrated,flat, transparent.This platform has improvements in many aspects,it is a secure,maintainable flexible and expandable platform.Ⅰbelieve,with the development of the e-government construct,the sharing supports platform,completed through the above method,has great improvements in the aspect of system integration,which not only retain the existing resources,but also develop the new system quickly and effectively.The purpose is to avoid the information isolated island and to realize the software multiply.
