My project is to implement a online video store. In this web page,member can check the movie information according the movie type,leading actor,leading actress,and employee who can sign on new member,update the member information,checking out,checking in and etc. And another feature is member can chat in my website with other members. Servlets are effective for developing Web-based solutions that help provide secure access to a Web site,that interact with databases on behalf of a client,that dynamically generate custom HTML documents to be displayed by browsers and that maintain unique session information for each client. The server is responsible for the database access.
Clients connect to the server using standard protocols available on all clent platforms.
Thus,the logic code can be written once and reside on the server for access by clients. Servlets are the analog on the server side to applets on the client side. Servlets are normally executed as part of a Web server. Architecturally,all servlets must implemetn the Servlet interface. Most servlets extend either GenericServlet or HttpServlet and override some or all of their methods with appropriate customized behaviors.
