So, fundamentally, any task JSP pages can perform could also be accomplished by servlets. However, this underlying equivalence does not mean that servlets and JSP pages are equally appropriate in all scenarios. The issue is not the power of the technology, it is the convenience, productivity, and maintainability of one or the other. After all, anything you can do on a particular computer platform in the Java programming language you could also do in assembly language. But it still matters which you choose.JSP provides the following benefits over servlets alone: It is easier to write and maintain the HTML. Your static code is ordinary HTML: no extra backslashes, no double quotes, and no lurking Java syntax.You can use standard Web-site development tools. Even HTML tools that know nothing about JSP can be used because they simply ignore the JSP tags.You can divide up your development team. The Java programmers can work on the dynamic code. The Web developers can concentrate on the presentation layer. On large projects, this division is very important. Depending on the size of your team and the complexity of your project, you can enforce a weaker or stronger separation between the static HTML and the dynamic content.Now, this discussion is not to say that you should stop using servlets and use only JSP instead. By no means. Almost all projects will use both. For some requests in your project, you will use servlets. For others, you will use JSP. For still others, you will combine them with the MVC architecture . You want the appropriate tool for the job, and servlets, by themselves, do not complete your toolkit.2. Advantages of JSP Over Competing TechnologiesA number of years ago, Marty was invited to attend a small 20-person industry roundtable discussion on software technology. Sitting in the seat next to Marty was James Gosling, inventor of the Java programming language. Sitting several seats away was a high-level manager from a very large software company in Redmond, Washington. During the discussion, the moderator brought up the subject of Jini, which at that time was a new Java technology. The moderator asked the manager what he thought of it, and the manager responded that it was too early to tell, but that it seemed to be an excellent idea. He went on to say that they would keep an eye on it, and if it seemed to be catching on, they would follow his company's usual "embrace and extend" strategy. At this point, Gosling lightheartedly interjected "You mean disgrace and distend."Now, the grievance that Gosling was airing was that he felt that this company would take technology from other companies and suborn it for their own purposes. But guess what? The shoe is on the other foot here. The Java community did not invent the idea of designing pages as a mixture of static HTML and dynamic code marked with special tags. For example, ColdFusion did it years earlier. Even ASP (a product from the very software company of the aforementioned manager) popularized this approach before JSP came along and 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..So, the question becomes: why use JSP instead of one of these other technologies? Our first response is that we are not arguing that everyone should. Several of those other technologies are quite good and are reasonable options in some situations. In other situations, however, JSP is clearly better. Here are a few of the reasons.2.1Versus .NET and Active Server Pages (ASP)NET is well-designed technology from Microsoft. is the part that directly competes with servlets and JSP. The advantages of JSP are two fold.First, JSP is portable to multiple operating systems and Web servers; you aren't locked into deploying on Windows and IIS. Although the core .NET platform runs on a few non-Windows platforms, the ASP part does not. You cannot expect to deploy serious applications on multiple servers and operating systems. For some applications, this difference does not matter. Forothers, it matters greatly.Second, for some applications the choice of the underlying language matters greatly. For example, although .NET's C# language is very well designed and is similar to Java, fewer programmers are familiar with either the core C# syntax or the many auxiliary libraries. In addition, many developers still use the original version of ASP. With this version, JSP has a clear advantage for the dynamic code. With JSP, the dynamic part is written in Java, not VBScript or another ASP-specific language, so JSP is more powerful and better suited to complex applications that require reusable components.You could make the same argument when comparing JSP to the previous version of ColdFusion; with JSP you can use Java for the "real code" and are not tied to a particular server product. However, the current release of ColdFusion is within the context of a J2EE server, allowing developers to easily mix ColdFusion and servlet/JSP code.2.2 Versus PHPPHP (a recursive acronym for "PHP: Hypertext Preprocessor") is a free, open-source, HTML-embedded scripting language that is somewhat similar to both ASP and JSP. One advantage of JSP is that the dynamic part is written in Java, which already has an extensive API for networking, database access, distributed objects, and the like, whereas PHP requires learning an entirely new, less widely used language. A second advantage is that JSP is much more widely supported by tool and server vendors than is PHP.2.3 Versus Pure ServletsJSP doesn't provide any capabilities that couldn't, in principle, be accomplished with servlets. In fact, JSP documents are automatically translated into servlets behind the scenes. But it is more convenient to write (and to modify!) regular HTML than to use a zillion println statements to generate the HTML. Plus, by separating the presentation from the content, you can put different people on different tasks: your Web page design experts can build the HTML by using familiar tools and either leave places for your servlet programmers to insert the dynamic content or invoke the dynamic content indirectly by means of XML tags.Does this mean that you can just learn JSP and forget about servlets? Absolutely not! JSPdevelopers need to know servlets for four reasons:JSP pages get translated into servlets. You can't understand how JSP works without understanding servlets.JSP consists of static HTML, special-purpose JSP tags, and Java code. What kind of Java code? Servlet code! You can't write that code if you don't understand servlet programming.Some tasks are better accomplished by servlets than by JSP. JSP is good at generating pages that consist of large sections of fairly well structured HTML or other character data. Servlets are better for generating binary data, building pages with highly variable structure, and performing tasks (such as redirection) that involve little or no output.Some tasks are better accomplished by a combination of servlets and JSP than by either servlets or JSP alone.2.4 ersus JavaScriptJavaScript, which is completely distinct from the Java programming language, is normally used to dynamically generate HTML on the client, building parts of the Web page as the browser loads the document. This is a useful capability and does not normally overlap with the capabilities of JSP (which runs only on the server). JSP pages still include SCRIPT tags for JavaScript, just as normal HTML pages do. In fact, JSP can even be used to dynamically generate the JavaScript that will be sent to the client. So, JavaScript is not a competing technology; it is a complementary one.It is also possible to use JavaScript on the server, most notably on Sun ONE (formerly iPlanet), IIS, and BroadVision servers. However, Java is more powerful, flexible, reliable, and portable.3. Misconceptions About JSPForgetting JSP Is Server-Side Technology,Here are some typical questions Marty has received (most of them repeatedly).Our server is running JDK 1.4. So, how do I put a Swing component in a JSP page?How do I put an image into a JSP page? I do not know the proper Java I/O commands to read image files.Since Tomcat does not support JavaScript,how do I make images that are highlighted when the user moves the mouse over them?Our clients use older browsers that do not understand JSP. What should we do?When our clients use "View Source" in a browser, how can I prevent them from seeing the JSP tags?All of these questions are based upon the assumption that browsers know something about the server-side process. But they do not. Thus:For putting applets with Swing components into Web pages, what matters is the browser's Java version—the server's version is irrelevant. If the browser supports the Java 2 platform, you use the normal APPLET (or Java plug-in) tag and would do so even if you were using non-Java technology on the server.You do not need Java I/O to read image files; you just put the image in the directory for Web resources (i.e., two levels up from WEB-INF/classes) and output a normal IMG tag.You create images that change under the mouse by using client-side JavaScript, referenced with the SCRIPT tag; this does not change just because the server is using JSP.Browsers do not "support" JSP at all—they merely see the output of the JSP page. So, make sure your JSP outputs HTML compatible with the browser, just as you would do with static HTML pages.And, of course you need not do anything to prevent clients from seeing JSP tags; those tags are processed on the server and are not part of the output that is sent to the client.Confusing Translation Time with Request Time,A JSP page is converted into a servlet. The servlet is compiled, loaded into the server's memory, initialized, and executed. But which step happens when? To answer that question, remember two points: The JSP page is translated into a servlet and compiled only the first time it is accessed after having been modified.Loading into memory, initialization, and execution follow the normal rules for servlets.The most frequently misunderstood entries are highlighted. When referring to the table, note that servlets resulting from JSP pages use the _jspService method (called for both GET and POST requests), not doGet or doPost. Also, for initialization, they use the jspInit method, not the init method.JSP page translated into servlet Servlet compiled Servlet loaded into server's memory jspInit called _jspService called.JSP技术概述作者:赞邦.朱利奥/赛克勒.迈克尔出处: 施普林格出版社(纽约公司)1.JSP的好处JSP页面最终会转换成服务程序。

现在,教师跟学生的之间的信息传播只在一指之间,为我们创造了方便快速的途径。
但在安全性和信息更新化方面存在有一定的不足,各现有系统资料单独建立,共享性差;在以管理者为主体的方式中,信息取舍依赖管理者对于信息的认知与喜好,较不容易掌握用户真正的需求,也因此无法完全满足用户的需求。
目前国家的教育体制也正处在不断改革、创新的阶段,我国教育部门充分吸取国外优秀的教学模式,结合国内多年的办学经验,逐步探索出适合中国特色的教学形式,国家教育部面向各级各类学校开展了全面学分制改革。
因此,教学管理软件应充分依托校园网,实现教学信息的集中管理、分散操作、信息共享,使传统的教学管理朝数字化、无纸化、智能化、综合化的方向发展,并为进一步实现完善的计算机教学文件管理系统和全校信息系统打下良好的基础。
21世纪是以高科技为核心的知识经济占主导地位的时代,国家的综合国力和国际竞争力将越来越取决于科学技术的创新水平。
计算机作为现代科学技术的创作工具,作为知识创新、传播和应用的基础,已经成为经济发展和社会进步的基础,计算机正在以前所未有的速度发展。
学校教育是培养和输送人才的摇篮,它随着人类进步的程度和地区的不同而变化,教育的口径不断扩宽,对教育的要求也不断提高。
在信息爆炸的时代,传统教学管理面临着诸多挑战。
我们学校的管理需要有先进的计算机技术来不断改进教学水平和教学质量,在学生成绩管理、学生选课管理、学生贷款管理等很多方面都需要计算机来完成。
学习和开发计算机网络技术,跟上当今世界不断发展的脚步,更要创造出属于自己的技术。
作为信息时代的学生,要有开阔的眼界,创新的思维,才能适应瞬息万变的社会,才能引领信息时代的潮流。
1.2课题现状随着学校规模的不断扩大,专业、班级、学生的数量急剧增加,有关学生选课的各种信息量也成倍增长,而目前许多高校的学生选课管理仍停留在复杂的人工操作上,重复工作较多,工作量大,效率低,保密性差,另外时间一长,将产生大量的文件和数据,这对于查找、更新和维护都带来了不少的困难。
因此,迫切需要开发基于互联网的学生网上选课系统来提高管理工作的效率。
基于互联网的学生网上选课系统作为计算机应用的一部分,使用计算机对选课信息进行管理,有着手工管理所无法比拟的优点,例如:检索迅速、查找方便、可靠性高、存储量大、保密性好、寿命长、成本低等。
这些优点能够极大地提高人事劳资管理的效率,在学生选课的规范管理、科学统计和快速查询方面具有较大的实用意义,它提高了信息的开放性,大大地改善了学生、教师对其最新信息查询的准确性,也是高校的科学化、正规化管理,与世界接轨的重要条件。
1.3课题目标学生网上选课系统是高校教学管理系统的重要组成部分。
熟悉教学管理工作的全部过程,从教务工作的实际出发,解决工作中关键性的难点问题,并充分利用计算机网络功能,实现教学工作全过程的计算机管理,帮助具体管理人员从复杂烦琐工作中解放出来。
使得教学管理走向无纸化办公和规范化、现代化管理。
由于Internet具有影响范围广,能够方便快捷的传递信息,具有近乎实时的交互性,本身又是一个巨大无比的信息库等诸多优点。
我们的目标是用学生网上选课系统实现最快对全校选修课程发布以及新闻发布,使教师和学生最快知道,创造现代化的学习环境。
学生选课是大学的主要管理工作之一,涉及到校、系、师、生的诸多方面,随着教学体制的不断改革,学生选课时的制约因素比较复杂,工作量也很大,而且往往需要在较短的时间内完成。
在这里,运用计算机辅助选课,即能实时地对大量选课数据进行检验和统计,十分方便地输出选课结果,同时也避免了人工处理时容易产生的错误。
因此,开发这样一套系统成为很有必要的事情。
1.4课题意义通过学生网上选课系统的实现,不仅可以提高自己的开发经验,也解决了实际的问题,提高了学校的办公管理的效率,减少了工作出错的几率,节约了资金成本。
2 网上选课系统需求分析2.1 需求分析2.1.1 系统目标学生选课系统作为一种现代化的教学技术,已越来越受到人民的重视。
是一个学校不可缺少的部分,它的内容对于学校的决策者和管理者来说都至关重要,所以学生选课系统应该能够为用户提供充足的信息和快捷的查询手段。
但一直以来人们使用传统人工的方式管理文件档案,这种管理方式存在着许多缺点,如:效率低、保密性差,另外时间一长,将产生大量的文件和数据,这对于查找、更新和维护都带来了不少的困难。
本系统应解决的问题有:实现教务处、教师及学生对选课工作的需求,提高对系统开发的认识与经验,将一些新的技术应用带到系统中来,保证系统的可维护性与可扩展性。
