1、毕业设计说明书英文文献及中文翻译 班 级: 学号: 姓 名: 学 院: 专 业: 指导教师: 年 月JSP and WEB technology1 JSP IntroductionJSP (JavaServer Pages) is a Java-based scripting technology. Is advocated by Sun Microsystems Inc., together with a number of companies involved in the establishment of a dynamic web page technology standards.
2、JSP technology is somewhat similar to ASP technology, It is a traditional HTML page file (*. htm, *. html) to insert Java program segment (Scriptlet) and JSP tag (tag), To form the JSP file(*jsp). Web development with JSP is a cross-platform applications that can run under Linux, but also in other o
3、perating systems. In the JSP of the many advantages, one of which is that it will be HTML encoded Web page from the business logic separated effectively. JSP access with reusable components, such as Servlet, JavaBean and Java-based Web applications. JSP also supports directly in the Web page embedde
4、d Java code. JSP can be used two ways to access documents: JSP documents sent by the browser request, the request sent to the Servlet. JSP technology uses Java programming language, XML-type tags and scriptlets, to have a package deal with the logic of dynamic pages. Page tags and scriptlets can als
5、o exist in the server access to the resources of the application logic. JSP logic and Web page design and display isolated and support reusable component-based design, Web-based applications more quickly and easily developed.The Web server when meets visits the JSP homepage the request, first carrie
6、s out segment, will then carry out the result code to return together with JSP in the document HTML for the customer. The insertion Java segment may operate the database, again the directional homepage and so on, realizes the function which the establishment dynamic homepage needs. JSP and Java Serv
7、let are the same, is in the server end execution, usually returns to this client side is a HTML text, therefore client side, so long as has the browser to be able to glance over.The JSP page is composed of the HTML code and the inserting Java code. The server in the page by the client side was reque
8、sted that later will carry on processing to these Java code, will then produce the HTML page will return gives the client side the browser. Java Servlet is the JSP technology base, moreover the large-scale Web application procedures development needs Java Servlet and the JSP coordination can complet
9、e. JSP had the Java technology simply easy to use, complete object-oriented, had the platform independency, and safe reliable, mainly faced Internets all characteristics.2 JSP computing techniqueTo carry on the dynamic website conveniently fast the development, JSP has made the improvement in the fo
10、llowing several aspects, causes it to become builds the cross platform fast the dynamic website first choice plan.2.1 carries on the content production and the demonstration separatesWith the JSP technology, the Web page development personnel may use HTML or the XML marking design and the formatted
11、final page, and uses the JSP marking or the tootsy produces on pages dynamic content originally. Production contents logic is sealed in marks and in the JavaBeans module, and ties up in the script, all scripts in server end movement. Because core logic is sealed in marks and in JavaBeans, therefore
12、the Web administrative personnels and the page designer, can edit and use the JSP page, but does not affect the content the production. In the server end, the JSP engine explained that the JSP marking and the script, produce the content which requested, and (or XML) pages form transmits the result b
13、y HTML the browser. This both are helpful in the author protects own code, and can guarantee any based on the HTML Web browsers complete usability.2.2 may entrust with heavy responsibility the moduleThe overwhelming majority JSP page relies on may entrust with heavy responsibility, the cross platfor
14、m module (JavaBeans or Enterprise the JavaBeans module) carries out complex processing which the application procedure requests. The development personnel can share and exchange the execution ordinary operation the module, or causes these modules uses for more users and the customer association. Has
15、 accelerated the overall development process based on modules method, and causes each kind of organization obtains balanced in their existing skill and in the optimized result development endeavor.2.3 uses markingThe Web page development personnel will not be the familiar script language programmers
16、. The JSP technology has sealed many functions, these functions are easy to use, marking to carry on the dynamic content production with JSP in the related XML to need. The standard JSP marking can visit and the instantiation JavaBeans module, the establishment or the retrieval module attribute, dow
17、nloads Applet, as well as the execution difficulty with codes and the time-consuming function with other methods.2.4 adapts the platformNearly all platforms support Java, JSP+JavaBeans to be possible to pass unimpeded nearly under all platforms. Transplants from a platform to other platform, JSP and
18、 JavaBeans does not even need to translate, because the Java byte code is standard has nothing to do with the platform.2.5 database connectionIn Java connects the database the technology is the JDBC, Java procedure is connected through the JDBC driver and the database, operations and so on execution
19、 inquiry, extraction data. Sun Corporation has also developed JDBC-ODBC bridge, uses this technical Java procedure to be possible to visit has the ODBC driver database, at present the majority database systems have the ODBC driver, therefore the Java procedure can visit such as Oracle, Sybase, MS SQ
20、L Server and databases and so on MS Access. In addition, through the development marking storehouse, the JSP technology may further expand. The third party development personnel and other personnel may found their marking storehouse for the commonly used function. This enables the Web page developme
21、nt personnel to be able to use the familiar tool and to be similar to marking same carries out the specific function component to carry on the work. The JSP technology very easy conformity to many kinds of application architecture, to use the extant tool and the skill, and can expand to the support
22、enterprise distributional application.3 Eclipse function synopsisMore and more Java development personnel already started the productivity which and the quality income appreciates Eclipse JDT to provide. It was the Java editor provides grammar Gao Liang to demonstrate that the formatting, the fold,
23、the content were auxiliary, code template and so on many functions. It grows unceasingly available restructuring and the code generation function set permits you in a higher rank the operation code, and automated usual code intensity duty and easy wrong duty. Moreover, in develops the code and uses
24、JDT to compile and to carry out the JUnit test built-in support carries on the unit testing after the code, may use Eclipse the first-class Java debugger debugging when the movement meets any question. Besides JDT, Eclipse SDK- the most popular Eclipse.org downloading - also contains Plug-in Develop
