1、毕业设计说明书英文文献及中文翻译 班 级： 学号： 软件学院姓 名： 软件工程学 院： 专 业： 指导教师： 2014 年 6 月JSP and WEB technology1 JSP Introduction JSP (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 techno
2、logy standards. 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
3、 also in other operating 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
4、Web page embedded 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 sc
5、riptlets can also 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 requ
6、est, first carries 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.
7、JSP and Java Servlet 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 cli
8、ent side was requested 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 coordi
9、nation can complete. 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 technique To carry on the dynamic website conveniently fast the development, JSP has made the im
10、provement in the following 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 separates With the JSP technology, the Web page development personnel may use HTML or the XML marking desig
11、n and the formatted 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 J
12、avaBeans, therefore 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 tr
13、ansmits the result by 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 module The overwhelming majority JSP page relies on may entrust with heavy responsibili
14、ty, the cross platform 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 cust
15、omer association. Has 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 marking The Web page development personnel will not be the familiar scrip
16、t language programmers. 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
17、 module attribute, downloads Applet, as well as the execution difficulty with codes and the time-consuming function with other methods.2.4 adapts the platform Nearly all platforms support Java, JSP+JavaBeans to be possible to pass unimpeded nearly under all platforms. Transplants from a platform to
18、other platform, JSP and JavaBeans does not even need to translate, because the Java byte code is standard has nothing to do with the platform.2.5 database connection In Java connects the database the technology is the JDBC, Java procedure is connected through the JDBC driver and the database, operat
19、ions and so on execution 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
20、as Oracle, Sybase, MS SQL 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 enable
21、s the Web page development 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 ca
22、n expand to the support enterprise distributional application.3 Eclipse function synopsis More 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 t
23、he formatting, the fold, 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 de
24、velops the code and uses 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
25、 contains Plug-in Development Environment(PDE). PDE used the specific function to expand JDT to construct the Eclipse plug-in unit - based on the Eclipse application procedure basic construction agglomeration. In fact, uses the tool which provides by Eclipse itself to be able to surmount the Java de
26、velopment, may expand the existing Eclipse application procedure, or even founds the brand-new application procedure. Eclipse by a script level constitution, contains in many functional modules or the Eclipse terminology so-called “the plug-in unit”. The plug-in unit is provides all functions in the
27、 Eclipse application procedure the module. They cooperate through its API to pay the final outcome together. In Eclipse, even the most foundations function, for instance the search and the start installments plug-in unit, seals in the plug-in unit. In order to expand the existing Eclipse function or
28、 carry on the construction in above, the plug-in unit the concrete expansion contribution for the expansion spot which will expose by other plug-in units. Usually, the plug-in unit concentrates the specific region responsibility, and gives through or a many expansion way other responsibility designa
29、tion other plug-in units. For example, a plug-in unit allows you parallel to compare two documents visibly the contents, but it will not care how to read these documents even how to explain these document structure; This is other plug-in units work. When compared with two documents, this plug-in uni
30、t first inspects whether to have another plug-in unit to be possible to explain these document structure. If found one, it to the plug-in unit inquiry related file organization information which found, and used this information in the comparison process. May see that the modular construction was Ecl
31、ipse has provided the huge flexibility, and provided one to be possible to support the massive application procedure platform which the original design has not expected.4 CSS synopsis The CSS edition method is the same with HTML, may also be any text editor or the homepage edition software, but also
32、 has uses for to edit CSS specially the software. If you write the CSS sentence regards the exterior cascading style sheet, but transfers in the HTML document, then its extension saves .css to be possible. Initially the technical personnel found out HTML, mainly stresses on the definition content, f
33、or instance expressed that a paragraph, indicates the title, but excessively has not designed HTML the typesetting and the contact surface effect. Along with the Internet rapid development, HTML is widely applied, the surfer people hoped certainly that the homepage makes attractive, therefore the HT
34、ML typesetting and the contact surface effects limitation exposes day by day. In order to solve this problem, the people also took many tortuous paths, has used some not good method, for instance increases many attribute results to HTML becomes the code very extremely fat, turns the picture the text
35、, excessively many comes the typesetting using Table, expresses the white space with the blank picture and so on. Appears until CSS. CSS may be a homepage design breakthrough, it has solved the homepage contact surface typesetting difficult problem. May such say that HTML Tag is mainly defines the h
36、omepage content (Content), but CSS decided how these homepage content does demonstrate (Layout). The CSS English is Cascading Style Sheets, Chinese may translate the tandem cascading style sheet. CSS may divide into three kinds according to its position: In inlays the style (Inline Style), internal
37、cascading style sheet (Internal Style Sheet), exterior cascading style sheet (External Style Sheet).5 HTML function synopsis Hyper Text Markup the Language hypertext mark language is one kind uses for to manufacture the hypertext documents the simple mark language. The hypertext documents which comp
38、iles with HTML are called the HTML documents, it can the independence in each kind of operating system platform (for example UNIX, WINDOWS and so on). HTML has served as since 1990 on World Wide Web the information to express the language, uses in describing the Homepage form design and it and on WW
39、W the other Homepage linked information. The HTML documents (i.e. the Homepage source document) was one has laid aside the mark ASCII text document, usually it had .html or the .htm document extension. Produces HTML documents mainly to have the following three ways: 1. the manual direct compilation
40、(e.g. ASCII text editor which or other HTML edition tool likes with you). 2. will have other form documents through certain format conversion tool (for example the WORD documents) to transform the HTML documents. 3. by the Web server (or said that the HTTP server) one only then real-time dynamic pro
41、duces. the HTML language is through uses each kind of mark (tags) to mark the documents the structure as well as marks the ultra chain (Hyperlink) the information. Although the HTML language described the documents structure form, but how cant define the documents information to precisely demonstrat
42、e and arrange, but is only suggested how the Web browser (for example Mosiac, Netscape and so on) should demonstrate and arrange these information, is decided finally in front of users demonstration result by the Web browsers demonstration style and to the mark explanatory ability. Why is the identi
43、cal documents the effect which demonstrated in the different browser meets is dissimilar. At present the HTML languages edition is 2.0, it is based on SGML (Standard Generalized Markup Language, standard sets at sign language generally, as soon as is applies mechanically describes digitized document
44、s structure and manages its content complex standard) a subset to evolve comes. Although in next editions standard HTML3.0 (is also called HTML+) to draw up, but some the partial experimental nature draft standard widely has been used, the mostly outstanding Web browser (for example Netscape and so
45、on) can explain in the HTML3.0 part new mark, therefore introduced in this chapter some HTML3.0 new mark has been accepted by the most browsers.6 Js script language synopsis JS is javascrip, Javascript is one kind the script language which comes by the Netscape LiveScript development, the main purpo
46、se is to solve the server terminal language, for instance Perl, carry-over speed question. At that time served the end to need to carry on the confirmation to the data, because the network speed was quite slow, only then 28.8kbps, the confirmation step wastes time were too many. Therefore Netscape b
47、rowser Navigator has joined Javascript, has provided the data confirmation basic function. The JavaScript official name is “ECMAScript”. This standard by ECMA organization development and maintenance. ECMA-262 is the official JavaScript standard. This standard based on JavaScript (Netscape) and JScr
48、ipt (Microsoft). Netscape (Navigator 2.0) Brendan Eich has invented this language, started from 1996, already appeared in all Netscape and in the Microsoft browser. The ECMA-262 development began in 1996, in 1997 July, the ECMA general meeting has accepted its first edition. Script script uses one s
49、pecific descriptive language, rests on certain form compilation to be possible the execution document, is also called as great or the batch run document. The script usually may transfer temporarily by the application procedure and carry out. Each kind of script present widely is applied in the homepage des
