Servlet technology gives programmers the greatest help is that it can handle a client to HTTP requests, and returns a response. Servlet is a Java class, the Java language to realize the function, basically can achieve Servlet (graphical interface outside). In general, Servlet technology has the following features:（1） High efficiency In the server only one Java virtual machine in operation, is its advantage when multiple requests from clients to access, Servlet for each request is assigned a thread rather than process.（2）Convenient Servlet provides a large utility routines, such as data processing, HTML form difficult to read and set the HTTP head, processing function of Cookie and the tracking session.（3）Cross platform Servlet with Java class write, it can run in the operating system platform is through and different application server platform.（4） The function is powerful In Servlet, many use traditional CGI procedure is very difficult to complete the task can be easily accomplished by Servlet technology. For example, Servlet can directly and Web server interaction, and ordinary CGI programs cant, Servlet also can share the data in each program between, so that the database connection pool is easy to realize the function such as.（5） Flexibility and scalability Using Servlet open Web application, because the Java class inheritance, constructors and other characteristics, which makes the application of flexible, can be arbitrarily extended.（6） Shared data Servlet can be achieved through the database connection pool data easily share. It can realize the management of user requests conveniently, simplifying the Session and get the previous page information operations, and in between CGI communication is very poor. Because each CGI procedure calls are the beginning of a new process, the communication between files to call through, so very slow. Communication between the same server on different CGI program quite troublesome.（7） Safety Some versions of CGI exist obvious security weaknesses, even using the latest standard and PERL language, the system also does not have the basic installation frame. The definition of Java a comprehensive security mechanism, including the SSLCA authentication, security policy specification.2.Business rule model2.1 Log:Associated objects:The user information, log information, the user level, published blog log view, the log comment informationRule description:User: log is stored, and the user of this log modify, delete, update, set the view permissions and other operations.2.2 Photo album management：Associated objects:Album information, user information, photo album upload information, blog, photo album browsing user level situationRule description:According to the users level, set up a number of different photos uploaded by the user on this album, delete, update, set the view permissions and other operations.2.3 Blog audit：Associated objects:The user name, Institute series of tables, the registration time.Rule description:Only is the school students and teachers to registering.2.4 Comment：Associated objects:The user name, date of publication, the log log sequence numberRule description:User login before comment.2.5 Management review：Associated objects:The user name, the log sequence number, serial number, date of review comments.Rule description:User login before management review, can view, modify and delete permissions on the published comments.3.Environmental Science3.1 Network environment Ethernet LAN3.2 The hardware environmentThe hardware development environment:Computer quantity: 3 sets.Each machine configuration:Processor: 733Memory: 256Hard disk: 20GInput and output devices: printer etc.Network equipment: Hub, network card, cable etc.The hardware running environment:Computer quantity: 30 setsThe system uses the C/S architecture, consisting of a server and multiple clients composition,Configuration is as follows:The server:
