1、大连交通大学 2011 届本科生毕业设计（论文）外文翻译 外文原文 The technique development history of JSP Writer: Bluce Rakel From: http:/ The Java Server Pages( JSP) is a kind of according to web of the script plait distance technique, similar carries the script language of Java in the server of the Netscape company of server- s
2、ide JavaScript( SSJS) and the Active Server Pages( ASP) of the Microsoft.JSP compares the SSJS and ASP to have better can expand sex, and it is no more exclusive than any factory or some one particular server of Web. Though the norm of JSP is to be draw up by the Sun company of, any factory can carr
3、y out the JSP on own system. The After Sun release the JSP( the Java Server Pages) formally, the this kind of new Web application development technique very quickly caused the peoples concern.JSP provided a special development environment for the Web application that establishes the high dynamic sta
4、te. According to the Sun parlance, the JSP can adapt to include the Apache WebServer, IIS4.0 on the market at inside of 85% server product. This chapter will introduce the related knowledge of JSP and Databases, and JavaBean related contents, is all certainly rougher introduction among them basic co
5、ntents, say perhaps to is a Guide only, if the reader needs the more detailed information, pleasing the book of consult the homologous JSP. A. Generalize The JSP(Java Server Pages) is from the company of Sun Microsystems initiate, the many companies the participate to the build up the together of th
6、e a kind the of dynamic the state web the page technique standard, the it have the it in the construction the of the dynamic state the web page the strong but the do not the especially of the function.JSP and the technique of ASP of the Microsoft is very alike. Both all provide the ability that mixs
7、 with a certain procedure code and is explain by the language engine to carry out the procedure code in the code of HTML. Underneath we are simple of carry on the introduction to it. C. JSP characteristics Is a service according to the script language in some one language of the statures system this
8、 kind of discuss, the JSP should be see make is a kind of script language. However, be a kind of script language, the JSP seemed to be too strong 大连交通大学 2011 届本科生毕业设计（论文）外文翻译 1 again, almost can use all Javas in the JSP. Be a kind of according to text originally of, take manifestation as the central
9、 development technique, the JSP provided all advantages of the Java Servlet, and, when combine with a JavaBeans together, providing a kind of make contents and manifestation that simple way that logic separate. Separate the contents and advantage of logical manifestations is, the personnel who renew
10、s the page external appearance need not know the code of Java, and renew the JavaBeans personnel also need not be design the web page of expert in hand, can use to take the page of JavaBeans JSP to define the template of Web, to build up a from have the alike external appearance of the website that
11、page constitute. JavaBeans completes the data to provide, having no code of Java in the template thus, this means that these templates can be written the personnel by a HTML plait to support. Certainly, can also make use of the Java Servlet to control the logic of the website, adjust through the Jav
12、a Servlet to use the way of the document of JSP to separate website of logic and contentses. Generally speaking, in actual engine of JSP, the page of JSP is the edit and translate type while carry out, not explain the type of. Explain the dynamic state web page development tool of the type, such as
13、ASP, PHP3 etc., because speed etc. reason, have already cant satisfy current the large electronic commerce needs appliedly, traditional development techniques are all at to edit and translate the executive way change, such as the ASP ASP+； PHP3 PHP4. In the JSP norm book, did not request the procedu
14、re in the JSP code part( be called the Scriptlet) and must write with the Java definitely. Actually, have some engines of JSP are adoptive other script languageses, such as the EMAC- Script, WebL etc., but actually this a few script languages also are to set up on the Java, edit and translate for th
15、e Servlet to carry out of. Write according to the norm of JSP, have no Scriptlet of relation with Java also is can of, however, mainly lie in the ability and JavaBeans, the Enterprise JavaBeanses because of the JSP strong function to work together, so even is the Scriptlet part not to use the Java,
16、edit and translate of performance code also should is related with Java. C. JSP mechanism To comprehend the JSP how unite the technical advantage that above various speak of, come to carry out various result easily, the customer must understand the differentiation of the module develops for the web
17、page of the center and the page develops for the web page of the center first. 大连交通大学 2011 届本科生毕业设计（论文）外文翻译 2 The SSJS and ASPses are all in several year agos to release, the network of that time is still very young, no one knows to still have in addition to making all business, datas and the expres
18、sion logic enter the original web page entirely heap what better solve the method. This kind of model that take page as the center studies and gets the very fast development easily. However, along with change of time, the people know that this kind of method is unwell in set up large, the Web that c
19、an upgrade applies the procedure. The expression logic write in the script environment was lock in the page, only passing to shear to slice and glue to stick then can drive heavy use. Express the logic to usually mix together with business and the data logics, when this makes be the procedure member
20、 to try to change an external appearance that applies the procedure but do not want to break with its llied business logic, apply the procedure of maintenance be like to walk the similar difficulty on the eggshell. In fact in the business enterprise, heavy use the application of the module already t
21、hrough very mature, no one would like to rewrite those logics for their applied procedure.HTML and sketch the designer handed over to the implement work of their design the Web plait the one who write, make they have to double work- Usually is the handicraft plait to write, because have no fit tool
22、and can carry the script and the HTML contentses knot to the server to put together. Chien but speech, apply the complexity of the procedure along with the Web to promote continuously, the development method that take page as the center limits sex to become to get up obviously. At the same time, the
23、 people always at look for the better method of build up the Web application procedure, the module spreads in customers machine/ server the realm. JavaBeans and ActiveX were published the company to expand to apply the procedure developer for Java and Windows to use to come to develop the complicate
24、d procedure quickly by the fast application procedure development ( RAD) tool. These techniques make the expert in the some realm be able to write the module for the perpendicular application plait in the skill area, but the developer can go fetch the usage directly but need not control the expertis
25、e of this realm. Be a kind of take module as the central development terrace, the JSP appeared. It with the JavaBeans and Enterprise JavaBeans( EJB) module includes the model of the business and the data logic for foundation, provide a great deal of label and a script terraces to use to come to show in the HTML page from the contents of JavaBeans creation or send a present in return. Because of the property that regards the module as the center of the JSP, it can drive Java and not the developer of Java uses equally.
