<p>現(xiàn)在本教程開始了，我們先講述簡單的 Servlet 和 XDoclet 組合。別忘了 XDoclet 擴展了 JavaDoc 引擎的概念從而使您能夠根據(jù)定制 JavaDoc 標記來生成代碼和其它文件。XDoclet 附帶的 Ant 任務(wù)使您能夠創(chuàng)建 <i>web.xml</i> 文件、ejb-jar.xml 文件和許多其它文件。在這一部分中，您將使用 XDoclet 和 <b>webdoclet</b> Ant 任務(wù)來生成 Web 應(yīng)用程序部署描述符。這是本教程中最簡單的嘗試。請注意標準的 Ant 分發(fā)版沒有附帶 XDoclet Ant 任務(wù)。</p>
<p>如果您以前用過 J2EE 技術(shù)，那么您知道 <i>web.xml</i> 文件是用來配置 Web 應(yīng)用程序的。<i>web.xml</i> 文件是 Web 應(yīng)用程序的部署描述符。XDoclet 使您能夠在 Servlet 源代碼中使用類似 JavaDoc 的標記來生成 <i>web.xml</i> 部署描述符。</p>
<p>以下 Servlet 指定了被用來生成 <i>web.xml</i> 文件的 XDoclet 標記。我們來快速地預(yù)覽一下，然后我將詳細介紹這些標記如何映射到 Web 應(yīng)用程序部署描述符（<i>web.xml</i>）中生成的元素。
