 摘   要
 目前，Java 2平臺(tái)有3個(gè)版本，它們是適用于小型設(shè)備和智能卡的Java 2平臺(tái)Micro版（Java 2 Platform Micro Edition，J2ME）、適用于桌面系統(tǒng)的Java 2平臺(tái)標(biāo)準(zhǔn)版（Java 2 Platform Standard Edition，J2SE）、適用于創(chuàng)建服務(wù)器應(yīng)用程序和服務(wù)的Java 2平臺(tái)企業(yè)版（Java 2 Platform Enterprise Edition，J2EE）。
  J2EE是一種利用Java 2平臺(tái)來(lái)簡(jiǎn)化企業(yè)解決方案中的與開發(fā)、部署和管理相關(guān)的復(fù)雜問題的體系結(jié)構(gòu)。J2EE技術(shù)是一套面向企業(yè)應(yīng)用的體系結(jié)構(gòu)，我們可以將J2EE理解為J2SE（Java 2 平臺(tái)的標(biāo)準(zhǔn)版）的擴(kuò)展和延伸，J2EE的基礎(chǔ)就是J2SE，J2EE不僅鞏固了標(biāo)準(zhǔn)版中的許多優(yōu)點(diǎn)，例如"編寫一次、到處運(yùn)行"的特性、方便存取數(shù)據(jù)庫(kù)的JDBC API、CORBA技術(shù)以及能夠在Internet應(yīng)用中保護(hù)數(shù)據(jù)的安全模式等等，同時(shí)還提供了對(duì) EJB（Enterprise JavaBeans）、Java Servlet API、JSP（Java Server Pages）以及XML技術(shù)的全面支持。其最終目的就是成為一個(gè)能夠使企業(yè)開發(fā)者大幅縮短投放市場(chǎng)時(shí)間的體系結(jié)構(gòu)。
  J2EE體系結(jié)構(gòu)提供了中間層集成框架，它是用來(lái)滿足那些無(wú)需太多費(fèi)用而又需要高可用性、高可靠性以及可擴(kuò)展性的應(yīng)用的需求。通過提供統(tǒng)一的開發(fā)平臺(tái)，可以使開發(fā)者在使用J2EE開發(fā)多層應(yīng)用時(shí)降低開發(fā)費(fèi)用和復(fù)雜性，同時(shí)提供對(duì)現(xiàn)有應(yīng)用程序集成強(qiáng)有力支持，完全支持Enterprise JavaBeans，有良好的向?qū)еС执虬�和部署�?yīng)用，添加目錄支持，增強(qiáng)了安全機(jī)制，提高了性能。
 Struts框架是一種非常優(yōu)秀的框架，是基于J2EE的MVC應(yīng)用框架,雖然從正式發(fā)布到現(xiàn)在已經(jīng)有五年多的時(shí)間，隨著該技術(shù)的逐步成熟，它已經(jīng)越來(lái)越多地運(yùn)用于企業(yè)平臺(tái)之上,許多大型網(wǎng)站已成功地應(yīng)用了Struts框架。本文在總結(jié)了Struts框架技術(shù)及其工作原理的基礎(chǔ)上，結(jié)合“基于web的課件信息管理系統(tǒng)”這個(gè)項(xiàng)目，實(shí)現(xiàn)了系統(tǒng)各個(gè)模塊的基本功能，這為今后更好的應(yīng)用Struts框架提供了參考。
本文結(jié)合實(shí)際項(xiàng)目的設(shè)計(jì)與開發(fā)對(duì)Struts框架進(jìn)行研究，對(duì)Struts框架及其工作原理進(jìn)行了介紹。同時(shí)，對(duì)開發(fā)過程中所應(yīng)用到的SERVLET，JSP，JAVA等技術(shù)作了相應(yīng)的介紹，規(guī)范的軟件開發(fā)流程介紹，以及軟件工程基本思想及各階段實(shí)現(xiàn)。
本文共分五個(gè)部分闡述了基于WEB的課件信息管理系統(tǒng)的結(jié)構(gòu)和設(shè)計(jì)實(shí)現(xiàn)過程。
 第一部分：介紹了J2EE發(fā)展過程中的兩大階段：Model 1 與Model 2，并分析兩者的優(yōu)缺點(diǎn)，對(duì)兩者進(jìn)行比較，指出Model2的優(yōu)越性。從而說(shuō)明使用基于Model2的Struts框架的優(yōu)勢(shì)。
 第二部分：對(duì)Struts框架進(jìn)行了介紹，闡述了框架的工作原理，并分析了Struts框架的優(yōu)缺點(diǎn)。
 第三部分：經(jīng)過認(rèn)真的調(diào)研，對(duì)系統(tǒng)的開發(fā)進(jìn)行了全面的需求分析，通過對(duì)系統(tǒng)的業(yè)務(wù)流程圖，用例模型，順序圖的描述與定義，確定了系統(tǒng)的總體流程 。
 第四部分：通過“基于WEB的課件信息管理系統(tǒng)”為例，來(lái)說(shuō)明如何設(shè)計(jì)基于Struts框架的Web應(yīng)用,以及在Struts框架中應(yīng)用自定義標(biāo)簽的具體實(shí)現(xiàn)過程。
 第五部分：介紹了在這次項(xiàng)目中用到的一些技術(shù)，例如Struts中自定義標(biāo)簽等。
 第六部分：對(duì)本次所做項(xiàng)目的一個(gè)總結(jié)。

Abstract
 At present, the platform of Java 2 have three editions,the first  is J2ME-Java 2 Platform Mirco Edition used to the small equiment and integlligent card,the second is J2SE-Java 2 Platform Standard Edition used to desktop system,the third J2EE-Java 2 Platfrom  Enterprise Edition is used to create application of sever and service.
 J2EE is kind of architecturewhich used to simplify the difficult which relevant of development. deployment and manament in enterprise solution. The basement of J2EE is the core of Java platform or the standard edition of Java 2. J2EE not only stabilize lots of excellence in standard edition,for example "write one time ,run everywhere",make the technique of  the saving of database include JDBC API、CORBA and so on,as well as the safe mode of protect data in  the application in Internet.It also provide the  integrated sustainment for EJB（Enterprise JavaBeans）、Java ervlets API、JSP（Java Server Pages）as well as XML.It's ultima thule is become one  architecture which can cut shorten the time to plunge into market for developer.
 J2EE provide the integrated  architecture satisfy the application demand which is high usability、high stability as well as expansibility .Through provide the unify platform of exploit,J2EE make the expenditure of exploit application of multilayer as well as provide strength sustainment to application of already exist, integrated sustainment for  Enterprise JavaBeans,having the better guide to sustain pack and dispose of application,the sustainment of insert category,strenghren the security,heighten the capability .
 The frame of Struts is a kind of real fair according to J2EE the MVC application frame, although from release to have already had time that five years have another till now formally, along with should be technical gradually mature, it has already been make use of in the business enterprise terrace more and more on, many large websites have already applied the frame of Struts successfully. This text combine" conference room book system" item in tallying up the Struts frame technique and it work the foundation of the principle, carrying out the basic function of the system each mold piece, this provided the reference for the better application  Struts frame of aftertime.
 This text passes the design and developments of the actual item to carry on the research to the frame of Struts, working to the frame of Struts and it the principle carried on the introduction. At the same time, in the folio hair process the XML, SERVLET, JSP apply to, JAVA etc. technique made the simple introduction, and the software development process of norm introduction, the software engineering basic thought and each stage realizations.
 Part 1: introduce the two greatest stages within the J2EE development processes respectively: Model 1 with Model 2, and analytical both of merit and shortcoming, carry on the comparison to both, point out Model2 superior sex.Thus explain the usage according to the advantage of the Model2 frame of Struts.
 Part  2: carry on the introduction to the frame of Struts, elaborate the principle of Struts, and analyzed the merit and shortcoming of the frame of Struts.
    Part 3: After serious survey，making a comprehensive assay of requirement for the system.Confirming the whole flow through  describing and defining the flow chart of business,model of case,chart of sequence.
 Part 4:  pass" sourceware managing system based on Web" of the whole project as an example, explain how to design according to the Web application of the frame of Struts,and use user-defined tag-libs.
 Part 5: In this part introduced In ths project used technology, for example  the taglibs and so on.
 Part  6: For this project to a summarize
