<p>虽然阅读示例有助于您理解本教程中的概念,但是大多数人通过亲自动手尝试这些示例学得更好。在尝试这些示例之前,必须已安装下列工具并且使它们正常运行:</p>
<ul>
<li>文本编辑器:Java 源文件只是纯文本文件,因此要创建和阅读它们,只需一个文本编辑器即可。也可以使用 Java IDE,但是有时 IDE 隐藏了太多的细节。<br>
<br>
</li>
<li>Java 开发环境,诸如 Java 2 SDK,它可以在 <a href="http://java.sun.com/j2se/1.4/">http://java.sun.com/j2se/1.4/</a> 上获得:Java 2 SDK 标准版版本 1.4 包含 JDBC 标准扩展以及 JNDI(Java 命名与目录接口),二者都是本教程中的一些示例所必需的。<br>
<br>
</li>
<li>符合 SQL 的数据库:本教程中的示例曾使用运行于 Windows 2000 Server 上的 DB2 进行过测试,但是由于它们是使用 <code>DataSource</code> 对象编写的,因此将它们转换成使用其它数据库(包括 Oracle 和 Microsoft SQL Server)应该非常容易。<a href="j-jdbcweb-5-3.html">JDBC 和数据库参考资料</a> 包含至有关 JDBC 和数据库的更多信息的链接。<br>
<br>
</li>
<li>JDBC 驱动程序:由于 JDBC API 主要由接口组成,因此必须获得一个实际的 JDBC 驱动程序实现以使本教程中的示例运行。这些示例使用了高级 JDBC 功能,因此需要一个高级 JDBC 驱动程序。包括 IBM 在内的大多数数据库和 JDBC 驱动程序供应商都提供特定 JDBC 驱动程序的评估版,IBM 为 DB2 提供了一个很好的 JDBC 驱动程序。<br>
<br>
</li>
<li>JSP 页面容器:需要这种容器以构建基于 JSP 的 Web 应用程序。servlet 与 JSP 技术规范的参考实现是 Apache Software Foundation 的 <a href="http://jakarta.apache.org/tomcat/">Jakarta Tomcat</a> 服务器,该服务器可以免费获取,本教程通篇都使用该服务器。<br>
<br>
</li>
<li>教程“Advanced database operations with JDBC”中的留言板表:这些表是为了在一个假定的留言板应用程序中使用而创建和填充的。本教程以这一应用程序为基础,并且需要这些表和数据以便能够正确地运行。本教程中的源代码可以从 <a href="j-jdbcweb-5-2.html">JSP 页面和 servlet 参考资料</a> 下载。<br>
