JSP and ASP
JSP (Java Server Pages) is advocated by Sun Microsystems, with many companies involved in the establishment of a dynamic web page technical standard. Show that the technology to create dynamic Web pages generated content provides a simple and rapid method. JSP technology is designed to make the job of building Web-based applications more easily and quickly, and these applications can with a variety of Web server, application server, browser and development tools work together. JSP norms are Web servers, application servers, transaction systems, as well as development tools vendors extensive cooperation between the results. In traditional web page HTML file (* htm, *. html) to add Java programs fragment (Scriptlet) and JSP tags (tag), has constituted the JSP page (*. jsp). Web Server page visits in the face of the request, the first implementation of the procedures fragment, and then the results in HTML format back to the customer. Procedures fragment can operate database, website re-orientation, etc. and send email, which is needed to create a dynamic Web site features. All procedures in the operation of the server-side implementation, network upload client gave only the result of the browser, the minimum requirements can be achieved without Plugin, no ActiveX, no Java Applet, even without Frame.
ASP(Active Sever Pages)Italy is “the dynamic server page”. ASP is Microsoft Corporation develops replaces the CGI script procedure one kind of application, it may carries on with the database and other procedures alternately, is one kind simple, the convenient programming tool. The ASP homepage document's form is .asp, now commonly used in each kind of dynamic website. ASP is one kind of server end script compilation environment, may use for to found and the movement dynamic homepage or the Web application procedure. The ASP homepage may contain the HTML mark, the ordinary text, the script order as well as the COM module and so on. May increase the interactive content using ASP to the homepage in (for example online form), may also found uses the HTML homepage to take the user interface the web application procedure.
JavaSever Pages technology and Microsoft's Active Sever Pages are similar in many respects, but there are still many differences, the essence of which lies in the distinction: they are different from technical specification, the basis for its realization: Web calls to the same server platform.
First .JSP the efficiency and safety of higher.
ASP stored in the form of source code, to explain the running, each ASP page calls on the source need to explain, operating efficiency is not high. In addition, the IIS has made many loopholes in the exposure source website.
JSP in the implementation of previous first to be compiled into byte code (byte code), the byte code from the Java Virtual Machine (Java Virtual Machine) to explain the implementation than the source explained the high efficiency; server also bytecode the Cache mechanism Bytecode can improve the efficiency of the visit. The first call may be slower JSP page because it has been compiled into Cache, the faster the future. JSP source at the same time is unlikely to be downloaded, especially JavaBean procedures can not put external directory.
Second.JSP components (Component) method more convenient.
ASP COM to expand through complex features such as file upload, send E-mail, as well as processing or will be separated from the complex calculation to become an independent reusable modules. JSP through JavaBean achieve the same function expansion. In the development, the development of COM complex than JavaBean, it is not difficult to learn ASP, COM Development Institute may simple. JavaBean simple and relatively more from the above examples of this can be seen in the development of JavaBean very convenient.
In the maintenance, COM must be registered on the server, if COM revised procedures, must be re-registered, and even to shut down and restart. JavaBean registration is not required, on the CLASSPATH included in the directory on the trip. If carried out a revision of JavaBean, and Tomcat JSWDK now also need to be closed and re-running (but not off), but the developer has promised to in future editions do not need to shut down the server.
In addition JavaBean is complete OOP can be dealt with the different business functions to facilitate the establishment of a set of reusable object libraries, such as user access control, E-mail auto-response, and so on.
Third.JSP adaptation broader platform.
ASP currently only applies to NT and IIS. Although under UNIX plug-in to support ChiliSoft ASP, ASP own limited functions, through a combination of ASP + COM to expand, UNIX, the COM is extremely difficult to achieve. JSP is different, almost all platforms support Java, JSP + JavaBean on all platforms without hindrance. Under NT IIS through a plug-in, for example, JRUN ( or ServletExec ( the JSP will be able to support. The famous Apache Web server has been able to support the JSP. As Apache widely used in the NT, UNIX and Linux, JSP is more extensive operating platform. Although NT operating systems make up a large share of the market, but the advantages of UNIX servers still great, and the new rise of Linux is vehement in the way they not small.
From one platform to another transplant a platform, JSP and JavaBean do not even have to recompile, because Java byte code standards and are platform-independent. I will be in the NT experimental JSP page intact get up and running under Linux, and feel very satisfied.
Java is the future development of the mainstream of technology, which has many advantages. JSP is Java in internet / intranet web applications, which is an important technology, has the support of major companies, it can be good and various Java technology to combine in order to achieve very complex applications. ASP there is a very strong vitality, but it Window depend on the vitality of the future vitality. JSP applicable to a variety of platforms, including NT. Suppose a site is based on linux / UNIX or solaris, aix, then JSP page is always preferred.
Fourth. JSP technology for the future
Microsoft recently launched DNA technology and it is ASP + COM / DCOM technology. JSP + Beans and completely similar, all the presentation layer completed by the ASP, all the business layer from COM / DCOM completed. By calling achieve integration. Why should we use these components technology?
Pure ASP / JSP language is very low efficiency of the implementation, if the user clicks on a large number of pure Script language quickly reached the ceiling of the function, and component technology will be able to substantially improve functional ceiling, speed up the implementation of speed.
Script layer and the business layer mixedîLanguage will be pure presentation together, causing inconvenience to amend, and the code can not be re-used. If you want to modify a place, often more than 10 pages will involve code on the use of component technology components can be changed only by. Therefore, the early Servlet is a flawed product, write a good business layer, presentation layer poor writing, and two mixed.
JSP+BAEN launch is to solve this issue, written with JSP presentation layer, the business layer with Bean wrote. SUN is the meaning of alternative future use JSP Servlet.
Java is promising. Microsoft split, and from the operating system supremacy, application software developers will find a common language to the development of development, Java dominating the world on the timing of that. If Microsoft split smoothly, the separation of application software from the company will become the new leader in Java. At present the leading Java SUN and IBM are stagnant, it is disappointing. Hope that the new company can reinvigorate. However, the new company may start and SUN Java standards war, the two sides of their respective standard-setting, cross-platform Java impact. In addition, the machines faster, the speed of Java disadvantage can be overcome soon.
Fifth.There are still some problems of JSP.
Java JSP only very familiar with the use of the talent is very good. JSP program faces debugging difficulties. JSP pages first to be converted to a. Java document (Servlet), and then been compiled. In this way, the error message is actually at the transformation that is not Java JSP document itself. For example, in the first line JSP document the error may be displayed for the first 20 lines. If passed the anti-tracking to try to resolve this problem would result sometimes baffling. (However, in Resin engine, can be wrong at the wrong documents to JSP) can also use some integrated design tools such as VAJ or JDeveloper IDE, but contrary to JSP easy-to-use features.
Database links is not so easy. Servlet engine does not support the majority of the local pool of links. Therefore, to write a lot of code is to accomplish this task.
It is difficult to choose suitable Servlet engine. Does not have an independent organization of the various engine to provide independent benchmark tests. Providers of course, their products provide a benchmark test, the findings are usually data format, are avoided stability.

JSP与ASP
JSP(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HTML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（Component）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Tomcat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presentationî 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，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只有对Java相当熟悉的人才能用得很好。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
