7、成日期 2012 年 4 月 13 日The technique development history of JSPThe 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- side JavaScript( SSJS) and the Active Server Pages

8、( JSP) of the Microsoft.JSP compares the SSJS and JSP 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 carry out the JSP on own system. The After Sun releas

9、e the JSP( the Java Server Pages) formally, the this kind of new Web application development technique very quickly caused the peoples concerns provided a special development environment for the Web application that establishes the high dynamic state. According to the Sun parlance, the JSP can adapt

10、 to include the Apache Web Server, IIS4.0 on the market at inside of 85% server product.This chapter will introduce the related knowledge of JSP and Databases, and Java Bean related contents, is all certainly rougher introduction among them basic contents, say perhaps to is a Guide only, if the read

11、er needs the more detailed information, pleasing the book of consult the homologous JSP.A. GeneralizeThe JSP(Java Server Pages) is from the company of Sun Microsystems initiate, the many companies the participate to the build up the together of the a kind the of dynamic the state web the page techni

12、que 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 functions and the technique of JSP of the Microsoft is very alike. Both all provide the ability that mixes with a certain procedure code and is explain by the la

13、nguage engine to carry out the procedure code in the code of HTML.Underneath we are simple of carry on the introduction to it.B. Source of JSPThe technique of JSP of the company of Sun, making the page of Web develop the personnel can use the HTML perhaps marking of XML to design to turn the end pag

14、e with format.Use the perhaps small script future life of marking of JSP becomes the dynamic state on the page contents.( the contents changes according to the claim of)The Java Servlet is a technical foundation of JSP, and the large Web applies the development of the procedure to need the Java Serv

15、let to match with with the JSP and then can complete, this name of Servlet comes from the Applet, the local translation method of now is a lot of, this book in order not to misconstruction, decide the direct adoption Servlet but dont do any translation, if reader would like to, can call it as small

16、service procedure”. The Servlet is similar to traditional CGI, ISAPI, NSAPI etc. Web procedure development the function of the tool in fact, at use the Java Servlet hereafter, the customer need not use again the lowly method of CGI of efficiency, also need not use only the ability come to born page

17、of Web of dynamic state in the method of API that a certain fixed Web server terrace circulate. Many servers of Web all support the Servlet, even not support the Servlet server of Web directly and can also pass the additional applied server and the mold pieces to support the Servlet.Receive benefit

18、in the characteristic of the Java cross-platform, the Servlet is also a terrace irrelevant, actually, as long as match the norm of Java Servlet, the Servlet is complete to have nothing to do with terrace and is to have nothing to do with server of Web. Because the Java Servlet is internal to provide

19、 the service by the line distance, need not start a progress to the each claimses, and make use of the multi-threading mechanism can at the same time for several claim service, therefore the efficiency of Java Servlet is very high.But the Java Servlet also is not to has no weakness, similar to tradi

20、tional CGI, ISAPI, the NSAPI method, the Java Servlet is to make use of to output the HTML language sentence to carry out the dynamic state web page of, if develop the whole website with the Java Servlet, the integration process of the dynamic state part and the static state page is an evil-forebodi

21、ng dream simply. For solving this kind of weakness of the Java Servlet, the SUN released the JSP.The JSP is an establishment at the model of Java servlets on of the expression layer technique, it makes the plait write the HTML to become more simple. Be like the SSJS, it also allows you carry the sta

22、tic state HTML contents and servers the script mix to put together the born dynamic state exportation.JSP the script language that the Java is the tacit approval, however, be like the JSP and can use other languages( such as JavaScript and VBScript), the norm of JSP also allows to use other language

23、s.C. JSP characteristicsIs a service according to the script language in some one language of the statures system this 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 again, almost can use all Javas in t

24、he JSP.Be a kind of according to text originally of, take manifestation as the central 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. Sep

25、arate the contents and advantage of logical manifestations is, the personnel who renews 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 templ

26、ate of Web, to build up a from have the alike external appearance of the website that 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 ma

27、ke use of the Java Servlet to control the logic of the website, adjust through the Java 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 t

28、he type of. Explain the dynamic state web page development tool of the type, such as JSP, 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 chang

29、e, such as the JSP JSP+;PHP3 PHP4.In the JSP norm book, did not request the procedure 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 languages, such as the EMAC- Script, Web etc., but actually this

30、a few script languages also are to set up on the Java, edit and translate for the 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 JavaBeans because of the JSP strong

31、function to work together, so even is the Scriptlet part not to use the Java, edit and translate of performance code also should is related with Java.D. JSP mechanismTo comprehend the JSP how unite the technical advantage that above various speak of, come to carry out various result easily, the cust

32、omer must understand the differentiation of the module develops for the web page of the center and the page develops for the web page of the center first. The SSJS and JSP are all in several years ago to release, the network of that time is still very young, no one knows to still have in addition to

33、 making all business, datas and the expression logic enter the original web page entirely heaped what better solve the method. This kind of model that takes 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 met

34、hod is unwell in set up large, the Web that can 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 lo

35、gics, when this makes be the procedure member to try to change an external appearance that applies the procedure but do not want to break with its lied business logic, apply the procedure of maintenance be like to walk the similar difficulty on the eggshell. In fact in the business enterprise, heavy

36、 use the application of the module already through 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 handicra

37、ft plait to write, because have no fit tool 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

38、 to get up obviously. At the same time, the people alway 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

39、 to use to come to develop the complicated 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 di

40、rectly but need not control the expertise of this realm.Is 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

41、 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. Not the developer of Java can pass the

42、 JSP label( Tags) to use the JavaBeans that the deluxe developer of Java establishes. The developer of Java not only can establish and use the JavaBeans, but also can use the language of Java to come to control more accurately in the JSP page according to the expression logic of the first floor Java

43、Beans. See now how JSP is handle claim of HTTP. In basic claim model, a claim directly was send to JSP page in. The code of JSP controls to carry on hour of the logic processing and module of JavaBeans hand over with each other, and the manifestation result in dynamic state burly, mixing with the HT

44、ML page of the static state HTML code. The Beans can be JavaBeans or module of EJBs.Moreover, the more complicated claim model can see make from is request other JSP pages of the page call sign or Java Servlets.The engine of JSP wants to chase the code of Java that the label of JSP, code of Java in

45、the JSP page evens all converts into the big piece together with the static state HTML contentses actually. These codes piece was organized the Java Servlet that customer can not see to go to by the engine of JSP, then the Servlet edits and translate them automatically byte code of Java. Thus, the v

46、isitant that is the website requests a JSP page, under the condition of it is not knowing, an already born, the Servlet actual full general that prepared to edit and translate completes all works, very concealment but again and efficiently. The Servlet is to edit and translate of, so the code of JSP

47、 in the web page does not need when the every time requests that page is explain. The engine of JSP need to be edit and translate after Servlet the code end is modify only once, then this Servlet that edited and translate can be carry out. The in view of the fact JSP engine auto is born to edit and translate the Servlet also, need not procedure member begins to edit and translate the code, so the JSP can bring vivid sex that function and fast developments need that you are efficiently.Compared with the traditional CGI, the JSP has the equal advantage
