JSP is the abbreviation of Java Server Pages. It is the technical standards of dynamic web page. Adding Java programs and JSP marks to the traditional HTML web page files makes JSP web page. The synthesis application network superiority and the user carry on the interaction Moreover JSP is opposite to the traditional homepage manufacture technology says, it has the obvious merit. JSP not like CGI, ISAPI and NSAPI equally difficulty with compiles and the maintenance, simultaneously equally only cannot adapt the small current capacity website like PHP, moreover has the good expansion, also equally does not receive the cross platform like ASP the limit, has solved this cross platform bottleneck. JSP has manifested now the most advanced website development thought.When web-server meets with request for linking JSP, it first executes the program parts. Then it brings the results back to the client with the aid of HTML. All programs are executed at servers.
The JSP inherits title the Java faces to the procedure speech of the object and the advantage of the cross-platform, combine can with close match in language in this marking in super text, compare with traditional the procedure of CGI, the JSP was significant to not only weave to write, carry out easy, but also increase the system carries out the ability. JSP technique has powerful functions and flexible ways of using. It provides a simple and direct way for the construction of the web page that can display dynamic contents.JavaServer Pages (JSP) technology, Sun's presentation model and part of the J2EE platform, has received significant attention.
JSP是Java Server Pages的縮寫(xiě)，是一種動(dòng)態(tài)網(wǎng)頁(yè)技術(shù)標(biāo)準(zhǔn)，在傳統(tǒng)的HTML網(wǎng)頁(yè)文件中，加入JAVA程序片段，和JSP標(biāo)記，就構(gòu)成了JSP網(wǎng)頁(yè)。JSP相對(duì)于傳統(tǒng)的網(wǎng)頁(yè)制作技術(shù)而言，它有著明顯的優(yōu)點(diǎn)。JSP不像CGI、ISAPI和NSAPI一樣難于編寫(xiě)和維護(hù)，同時(shí)不像PHP一樣只能適應(yīng)中小流量的網(wǎng)站，而且具有良好的擴(kuò)充性，也不像ASP一樣受到跨平臺(tái)的限制，解決了這個(gè)跨平臺(tái)的瓶頸。JSP體現(xiàn)了當(dāng)今最先進(jìn)的網(wǎng)站開(kāi)發(fā)思想。WEB服務(wù)器在遇到訪問(wèn)JSP的請(qǐng)求時(shí)，首先執(zhí)行其中的程序片段，然后將執(zhí)行結(jié)果以HTML方式返回給客戶(hù)。所有的程序都在服務(wù)器端執(zhí)行。
JSP承襲了Java面向?qū)ο蟮某绦蛘Z(yǔ)言能力與跨平臺(tái)的優(yōu)勢(shì)，并能與超文本標(biāo)記語(yǔ)言緊密配合，與傳統(tǒng)的CGI程序相比，JSP不僅編寫(xiě)、執(zhí)行容易，也大幅度提高了系統(tǒng)的執(zhí)行能力。JSP技術(shù)功能強(qiáng)大，使用靈活，為創(chuàng)建顯示動(dòng)態(tài)內(nèi)容的WEB頁(yè)面提供了一個(gè)簡(jiǎn)捷而快速的方法。JSP技術(shù)的設(shè)計(jì)目的是使編寫(xiě)基于WEB的應(yīng)用程序更加容易和快捷的同時(shí)，保證這些應(yīng)用程序能與各種的WEB服務(wù)器，瀏覽器和開(kāi)發(fā)工具共同工作。JavaServer Pages (JSP)技術(shù)，作為 Sun 公司的表示模型和 J2EE平臺(tái)的一部分，受到了極大關(guān)注。
