7、在单位 信息科学系软件工程教研室 教研室主任 刘瑞杰 完成日期 2012 年 4 月 13 日JSP and ASPJSP (Java Server Pages) by Sun Microsystems is company advocates, many companies involved in together set up a dynamic web technology standards. This technology to create display produce content for dynamic Web page provides a simple and rapi
8、d method. JSP technology the design purpose is to make the structure based on Web application more easy and efficient, and these applications can and various Web server, application server, the browser and development tools to work together. The JSP specification is Web server, application server, t
9、rading system, and the development tools suppliers of the extensive cooperation between the results. In the traditional web HTML files (* HTM, *. HTML) with Java program segment (Scriptlet) and JSP mark (tag), constitutes the JSP page (*. JSP). Web servers to meet the request of JSP page visit, the
10、first executive one of the fragments, and then will carry out the results in HTML format back to the customer. Fragments can operate the database, redirected web page and send email, etc. This is a dynamic web site needs to function. All the programs are executed on the server, the network to the cu
11、stomer is the only upload the results of the requirements of the client browser to minimum, can achieve without Plugin, no ActiveX, no Java Applet, and even without Frame.ASP (Active Sever Pages) means Active server Pages. ASP is Microsoft company developed the CGI scripts to replace a applications,
12、 it can and database and other procedures interaction, is a simple and convenient programming tools. ASP page file format is. ASP, now often used in all kinds of dynamic web site. ASP is a server-side scripting writing environment, can be used to create and run dynamic Web pages or Web applications.
13、 ASP page can contain HTML tags, the common text, script commands and COM components, etc. Using ASP can add interactive content to the web (such as online form), can also create use HTML web as a user interface web applications.Java Sever Pages technology and Microsoft Active Sever Pages in many wa
14、ys have similar, but there are still many different, one of the most essential difference is that they are from different specification organization, its realization basis: Web server platform requirement is not the same.(1) the JSP efficiency and safety of higherASP in source code form deposit, to
15、explain the way operation, every time ASP page calls all need to explain to the source code, efficiency is not high. In addition, the loophole has made many IIS website source program big exposure.In the implementation of the JSP before compiled into bytecode (byte code), by the Java bytecode Virtua
16、l Machine (Java Virtual Machine) explain implementation, source of high efficiency than explanation; The server and the bytecode Cache mechanism, can improve the efficiency of the bytecode visit. The first call JSP page may be a bit slow, because it has been compiled into by using locally cached inf
17、ormation more quickly after they. At the same time JSP source program is unlikely to be downloaded, especially JavaBean program can in no foreign directory.(2) JSP components (Component) way more convenientASP through the COM to expand complex functions, such as file upload, send E-mail and business
18、 processing or complex calculation isolated became an independent reusable module. JSP JavaBean realized through the same function expansion. The development, the development of the COM than JavaBean complex, learn ASP is not easy, but learn to develop COM dont simple. And is relatively simple JavaB
19、ean much, from this paper the above example can be seen in the development JavaBean very convenient.In maintenance, COM must be registered with the server, if modified the COM program, you must register to even have to shut down and restart. JavaBean is not need to register, and put in the CLASSPATH
20、 include directory will do. If JavaBean change, the JSWDK and Tomcat now need to be closed and restart the still (but not shut down), but developers have promised will later version do not need to shut down the server.Another JavaBean is completely OOP, can according to the different business proces
21、sing function easily established a reusable object library, for example the user access control, E-mail auto reply, and so on.(3) JSP adapt to a wider platformASP is currently only apply to NT and IIS. Although UNIX have ChiliSoft plugin to support ASP, but the function of ASP itself limited, must t
22、hrough the ASP and COM combination to expand, UNIXs COM realize up very difficult. JSP is different, almost all platform support Java, JSP + JavaBean can be in all the workbench came unstuck. NT through a plugin next IIS, for example JRUN ( or ServletExec ( can support JSP. The famous Apache Web ser
23、ver has been able to support JSP. Apache due to widely used in the NT, UNIX and Linux, so the JSP to a broader operation platform. Although now NT operating systems for a large market share, but on the server side the advantage of UNIX is still very strong, and of the emergence of Linux is not small
24、 breaks.From a platform transplant to another platform, JSP and JavaBean dont even have to recompile the, because Java bytecode are standard has nothing to do with the platform. The author in the JSP page under NT intact get Linux running under it, and feel very satisfied.Java is the mainstream of t
25、he future development of technology, has many advantages. JSP is Java in the Internet/Intranet web on important application technology, got the companys support, it can and all kinds of Java technology in together, so as to realize the very complex applications. ASP also has the very strong vitality
26、, but its vitality attached to the Window the vitality of the future. JSP applicable to all platforms, including NT. Suppose that a site is based on UNIX/Linux or solaris, aix, so with JSP always is first selection page language.(4) JSP about the future of technologyMicrosoft recently launched the D
27、NA technology, simply said, that is + COM/DCOM ASP technology. And JSP + Beans exactly as, all of the presentation layer by ASP finished, all the business layer by COM/DCOM completed. Through the calls, realize the integration. Why to want to use these component technology?Simple ASP/JSP language is
28、 very low efficiency of the execution, if appear a large Numbers of users click, pure Script language soon arrived at the cap on its function, and component technology can greatly improve the function limit, speed up execution speed.Pure language Script will presentationi layer and business layer mi
29、x together, cause to change without convenient, and code cant use again. If want to modify a place, often involves more than ten page code, using component technology is only a reorganization. So, Servlet is an early not perfect products, write business layer is very good, write presentation layer i
30、s poor, and the two layers of hybrid.JSP + BAENs launch is used to solve this problem, with JSP write presentation layer, with Bean write business layer. SUN their meaning is the future with JSP alternative Servlet.Java is far. Microsoft split, the operating system will be at and up, application sof
31、tware developers must want to find a universal design language of development, Java unification world time is up. If Microsoft split smooth, from which the application software company gives the new leader will be Java. Java current leading SUN and IBM have inanimate, disappointing. Hope the new com
32、pany can inject new vitality. However, the new company is very likely and SUN on Java standard war, both sides respective set the standards, influence Java cross-platform. In addition, now of the machine speed more and more quickly, Java speed can be overcome disadvantage soon.(5) JSPs problemsJSP p
33、rogram test difficulty. The JSP page was first into a Java files (Servlet), and then be compiled. So, error messages in fact to the transformation of the Java is a file and not JSP itself. For example in the JSP error can be done first documents show for line 20. If trying to reverse tracking to sol
34、ve this problem sometimes to make the result puzzling (but, in Resin engine, the error has to file the error can be JSP line), also can use some integrated design tools such as VAJ or JDeveloper IDE, but it goes against all JSP easy-to-use features.The database connection is not so easy. Most Servle

Not a single organization to provide independent benchmark test all the engine. Provider of course to own products provide a benchmark
36、 test, but the conclusion in data are usually form, all avoid stability.JSP与ASPJSP(Java Server Pages)是由Sun Microsystems公司倡导,许多公司参与一起建立的一种动态网页技术标准。该技术为创建显示动态生成内容Web页面提供了一个简捷而快速的方法。JSP技术的设计目的是使得构造基于Web的应用程序更加容易和快捷，而这些应用程序能够与各种Web服务器，应用服务器，浏览器和开发工具共同工作。JSP的规范是Web服务器、应用服务器、交易系统、以及开发工具供应商间广泛合作的结果。在传统的网页H
37、TML文件(*htm,*.html)中加入Java程序片段(Scriptlet)和JSP标记(tag)，就构成了JSP网页(*.jsp)。Web服务器在遇到访问JSP网页的请求时，首先执行其中的程序片段，然后将执行结果以HTML格式返回给客户。程序片段可以操作数据库、重新定向网页以及发送 email 等等，这就是建立动态网站所需要的功能。所有程序操作都在服务器端执行，网络上传送给客户端的仅是得到的结果，对客户浏览器的要求最低，可以实现无Plugin，无ActiveX，无Java Applet，甚至无Frame。ASP(Active Sever Pages) 意为“动态服务器页面”。ASP是微软
38、公司开发的代替CGI脚本程序的一种应用,它可以与数据库和其它程序进行交互，是一种简单、方便的编程工具。ASP的网页文件的格式是.asp，现在常用于各种动态网站中。ASP是一种服务器端脚本编写环境，可以用来创建和运行动态网页或Web应用程序。ASP网页可以包含HTML标记、普通文本、脚本命令以及COM组件等。利用ASP可以向网页中添加交互式内容（如在线表单），也可以创建使用HTML网页作为用户界面的web应用程序。Java Sever Pages技术和微软的Active Sever Pages在许多方面都有相似的，但仍然存在很多不同之处，其中最本质上的区别在于：两者是来源于不同的技术规范组织，其
39、实现的基础：Web服务器平台要求不相同。（1）JSP的效率和安全性更高ASP以源码形式存放，以解释方式运行，每次ASP网页调用都需要对源码进行解释，运行效率不高。另外，IIS的漏洞曾使得许多网站源程序大曝光。JSP在执行以前先被编译成字节码（byte code），字节码由Java虚拟机（Java Virtual Machine）解释执行，比源码解释的效率高；服务器上还有字节码的Cache机制，能提高字节码的访问效率。第一次调用JSP网页可能稍慢，因为它被编译成Cache，以后就快得多了。同时JSP源程序不大可能被下载，特别是JavaBean程序完全可以放到不对外的目录中。（2）JSP的组件（C
40、omponent）方式更方便ASP通过COM来扩充复杂的功能，如文件上载、发送E-mail以及将业务处理或者复杂计算分离出来成为独立可重复利用的模块。JSP通过JavaBean实现了同样的功能扩充。在开发方面，COM的开发远比JavaBean复杂，学会ASP不难，但学会开发COM可不简单。而JavaBean就相对简单多了，从本文上述示例中可以看出开发JavaBean很方便。在维护方面，COM必须在服务器上注册，如果修改了COM程序，就必须重新注册，甚至必须关机和重新启动。JavaBean则不需要注册，放在CLASSPATH包含的目录中就行了。如果JavaBean进行了修改，则JSWDK和Tom
41、cat现在还需要关闭和重新运行（但不是关机），但开发者已经许诺将在以后的版本中做到不需要关闭服务器。另外JavaBean是完全的OOP，可以针对不同的业务处理功能方便地建立一整套可重复利用的对象库，例如用户权限控制、E-mail自动回复等等。（3）JSP的适应平台更广ASP目前仅适用于NT和IIS。虽然UNIX下有ChiliSoft的插件来支持ASP，但是ASP本身的功能有限，必须通过ASP+COM的组合来扩充，UNIX下的COM实现起来非常困难。JSP则不同，几乎所有平台都支持Java，JSP+JavaBean可以在所有平台下通行无阻。NT下IIS通过一个插件，例如JRUN（http：/从一
42、个平台移植到另外一个平台，JSP和JavaBean甚至不用重新编译，因为Java字节码都是标准的与平台无关的。笔者将在NT下实验的JSP网页原封不动地拿到Linux下就运行起来了，感觉非常满意。Java是未来的主流开发技术，具有很多优势。JSP则是Java在internet/intranet web上的重要应用技术，得到了各大公司的支持，它可以和各种Java技术完好地结合在一起，从而实现非常复杂的应用。ASP也有很强的生命力，但它的生命力依附于Window未来的生命力。JSP适用于各种平台，包括NT。假设一个站点是基于linux/UNIX或者solaris、aix等，那么JSP总是首选的页面语
43、言。（4）JSP技术的未来 微软前不久推出的DNA技术，简单说，就是ASP+COM/DCOM技术。与JSP+Beans完全类似，所有的presentation layer由ASP完成，所有的business layer由COM/DCOM完成。通过调用，实现整合。为什么要采用这些组件技术呢？单纯的ASP/JSP语言是非常低效率执行的，如果出现大量用户点击，纯Script语言很快就到达了它的功能上限，而组件技术就能大幅度提高功能上限，加快执行速度。纯Script语言将presentation layer和business layer混在一起，造成修改不方便，并且代码不能重复利用。如果想修改一个地方
44、，经常会牵涉到十几页代码，采用组件技术就只改组件就可以了。所以，Servlet是一个早期的不完善的产品，写business layer很好，写presentation layer就差，并且两层混杂。JSP+BAEN的推出正是用来解决这个问题的，用JSP写presentation layer，用Bean写business layer。SUN自己的意思也是将来用JSP替代Servlet。Java实在前途远大。微软分拆后，操作系统将群雄并起，应用软件的开发商必定要找一个通用开发语言进行开发，Java一统天下的时机就到了。如果微软分拆顺利，从中分出的应用软件公司将成为Java的新领导者。Java目前的
45、主导SUN和IBM都死气沉沉，令人失望。希望新公司能注入新活力。不过，新公司很有可能和SUN展开Java标准大战，双方各自制定标准，影响Java跨平台。另外，现在的机器速度越来越快，Java的速度劣势很快就可以被克服。（5）JSP存在的一些问题JSP程序调试困难。JSP页面首先被转化为一个java文件（Servlet），然后再被编译。这样，出错信息实际上指向的是经过转化的那个Java文件而不是JSP本身。例如在JSP文件第1行的错误可能被显示为第20行。如果试图通过反跟踪来解决这个问题有时会使结果莫名其妙（但是，在Resin引擎中，错误已经可以指向JSP文件的出错行），也可以使用一些集成设计工具IDE如VAJ或JDeveloper，但这有悖于JSP简单易用的特性。数据库链接并不那么容易。大多数Servlet引擎并不支持本地的缓冲池链接。因此，不得不写很多代码来完成这项工作。很难选择合适的Servlet引擎。没有一个独立组织来对各种引擎提供独立benchmark测试。提供商当然对自己的产品提供了benchmark测试，但结论通常以数据形式给出，均回避稳定性。大连交通大学信息工程学院毕业设计(论文)调研报告学生姓名 詹英杰 专业班级 软件工程08-1班 指导教师 常敬岩史原 职 称 高工讲师 所在单位 信息科学系软件工程教研室 教研室主任 刘瑞杰 完
