I'm going to assume that, like most Java programmers, you know what JavaServer Pages (JSP) and Extensible Markup Language (XML) are, but you may be a little unclear on how you can use them. JSP use is pretty easy to defend. It allows you to design a Website built from files that look and act a lot like HTML. The only difference is that JSPs also act dynamically -- for example, they can process forms or read databases -- using Java as a server-side scripting language. XML use is more difficult to justify. While it seems as if every new product supports it, each one seems to be using XML for a different purpose.
In this article, you will learn to design a system using XML in a fairly modest way. Many Websites have vast collections of data that are displayed in a more or less standard way. I will design a system that uses XML files to store data on a Web server and JSP files to display that data.

我們?cè)诖思僭O(shè)你已經(jīng)了解javaserver pages(jsp)和extensible markup language (xml)。但也許你對(duì)該如何綜合使用它們?nèi)匀挥行┟曰蟆sp的應(yīng)用很容易，你可以用它設(shè)計(jì)網(wǎng)頁(yè)，使之看起來(lái)似乎和html一樣。唯一的不同是jsp是動(dòng)態(tài)執(zhí)行的。例如，它們可以處理表單form和讀寫數(shù)據(jù)庫(kù)。xml的應(yīng)用的說(shuō)明則比較困難。似乎所有的產(chǎn)品都支持它，每個(gè)人也好象都以各種不同目的在使用它。

在本文中，你可以看到如何使用一種相當(dāng)先進(jìn)的方式用xml來(lái)設(shè)計(jì)一個(gè)系統(tǒng)。許多站點(diǎn)有巨量數(shù)據(jù)收集并以一種很標(biāo)準(zhǔn)或很不標(biāo)準(zhǔn)的方式來(lái)顯示它們。我將設(shè)計(jì)一個(gè)系統(tǒng)，它使用xml文件在web服務(wù)器上進(jìn)行存儲(chǔ)，并用jsp來(lái)顯示數(shù)據(jù)。
