【正文】 (a product from the very software pany of the aforementioned manager) popularized this approach before JSP came alongand decided to jump on the bandwagon. In fact, JSP not only adopted the general idea, it even used many of the same special tags as ASP did. 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 bee more like the SSJS, it also allows you carry the static 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 ASP and can use other languages( such as JavaScript andVBScript), the norm of JSP also allows to use other languages.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 the 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 bine 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 renews the page external appearance need not know the code of Java, and renew the JavaBeans personnel also need not be design the web pageof 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 page constitute. JavaBeans pletes 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 , can also make use of the Java Servlet to control the logic of the website, adjustthrough the Java Servlet to use the way of the document of JSP to separate website of logicand contents. 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 ASP, PHP3 etc., because speed etc. reason, have already can39。畢 業(yè) 設 計（論 文） 英 文 翻 譯課題名稱系 部專 業(yè)班 級學 號姓 名指導教師2 0 年 月 日畢業(yè)設計外文翻譯原 稿Introduction 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 pany of serverside JavaScript( SSJS) and the Active Server Pages( ASP) of the pares 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 pany of, any factory can carry 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 people39。t satisfy current the large electronic merce needs appliedly, traditional development techniques are all at to edit and translate the executive way change, such as the ASP → ASP+。JSP比SSJS和ASP具有更好的可擴展性,并且它不專屬于任何一家廠商或某一特定的Web服務器。按照Sun 的說法,JSP 能夠適應市場上包括Apache WebServer、%的服務器產品。兩者都提供在HTML 代碼中混合某種程序代碼、由語言引擎解釋執(zhí)行程序代碼的能力。然而,這種底層的等同性并不意味著servler和JSP頁面對于所有的情況都等同適用。JSP中可以使用常規(guī)的HTML:沒有額外的反斜杠,沒有額外的雙引號,也沒有暗含的Java語法。Java程序員可以致力于動態(tài)代碼。在此,這個討論并不是讓您停止使用servlets,只使用JSP。B. JSP的由來Sun公司的JSP技術,使Web頁面開發(fā)人員可以使用HTML或者XML標識來設計和格式化最終頁面。許多Web 服務器都支持Servlet,即使不直接支持Servlet的Web 服務器也可以通過附加的應用服務器和模塊來支持Servlet。為了解決Java Servlet的這種缺點,SUN 推出了JSP?！痹诖? Gosling的抱怨顯示出,他感到這個公司會從其他公司那里拿走技術,?這次鞋子穿在了另一只腳上。實際上,JSP不只采用了這種通用概念,它甚至使用許多和ASP相同的特殊標簽。C. JSP 的特點按照腳本語言是服務于某一個子系統(tǒng)的語言這種論述,JSP應當被看作是一種腳本語言。JavaBeans類完成數據提供,這樣在模板中就沒有Java代碼,這意味著這些模板可以由一個HTML編寫人員來維護。在JSP規(guī)范書中,并沒有明確要求JSP中的程序代碼部分(稱為Scriptlet)一定要用Java來寫。SSJS和ASP都是在幾年前推出的,那時網絡還很年輕,沒有人知道除了把所有的商務、數據和表達邏輯統(tǒng)統(tǒng)堆進原始網頁中之外還有什么更好的解決方法。表達邏輯通常和商務及數據邏輯混在一起,這使得當程序員試圖改變一個應用程序的外觀而不想破壞與之緊密結合的商務邏輯時,應用程序的維護就像在蛋殼上走路一樣困難。與此同時,人們一直在尋找建立Web應用程序的更好方法,組件在客戶機/服務器領域流行起來。它以JavaBeans和EnterpriseJavaBeans(EJB)組件包含商務和數據邏輯
