1、按书中要求先建立ActionForm.java、RegisterAction.java、struts-config.xml和三个页面并依照书中介绍部署在Tomcat下2、我使用的环境是jb，按照书中介绍部署好的应用在编译时会遇到如下问题：a、找不到UserDirectory类b、找不到struts-html.tld文件3、解决方法a、新建UserDirectory和UserDirectory类，可以在某位网友的blog上找到[url]http://blog.matrix.org.cn/page/xy_cq01/?anchor=userdirectory_%E4%B8%8E_userdirectoryexception[/url]代码如下：/** $Header: /home/cvspublic/jakarta-struts/src/example/org/apache/struts/example/LogoffAction.java,v 1.4 2000/09/23 22:53:53 craigmcc Exp $* $Revision: 1.4 $* $Date: 2000/09/23 22:53:53 $** ====================================================================** The Apache Software License, Version 1.1** Copyright (c) 1999 The Apache Software Foundation.
