web|項目 起初的工程（未引入Struts）目錄結構如下：
修改你的web.xml配置
如下：
修改之前是：
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app><!-- The mapping for the default servlet --><servlet><servlet-name>estservlet</servlet-name><servlet-class>action.JDBCServlet</servlet-class></servlet><servlet-mapping><servlet-name>estservlet</servlet-name><url-pattern>/estservlet</url-pattern></servlet-mapping><servlet><servlet-name>delconad</servlet-name><servlet-class>action.delConadBean</servlet-class></servlet><servlet-mapping><servlet-name>delconad</servlet-name><url-pattern>/delconad</url-pattern></servlet-mapping></web-app>

引入Struts所需的標籤庫
引入目錄結構如下：（設定檔描述）
在工程中引入Struts工程所需的.jar檔案
目錄結構如下：
引入資源檔：
ApplicationResources.properties
內容如下：
# -- buttons --button.submit=Submitbutton.cancel=Cancelbutton.confirm=Confirmbutton.reset=Resetbutton.save=Save
現在編寫一個測試代碼：
編寫一個提交資料庫的表單jsp檔案useStruts.jsp：
如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><%@ page language="java" contentType="text/html; charset=utf-8" %><%@ taglib url="/WEB-INF/struts-html.tld" prefix="html" %><%@ taglib url="/WEB-INF/struts-bean.tld" prefix="bean" %><html:html xhtml="true" locale="true"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>使用 Struts DynaActionForm 插入Mysql資料庫</title><html:base/><link rel="stylesheet" type="text/css" href="../css/example.css" /></head><body><html:errors/><html:form action="/insertmysql.do"><p>使用者：<br/><html:text property="user" size="40" maxlength="20"/></p><p>密碼：<br/><html:text property="password" size="40" maxlength="20"/></p><p>標題:<br/><html:text property="title" size="40" maxlength="50"/></p><p>內容:<br/><html:text property="content" size="40" maxlength="50"/></p><p>作者:<br/><html:text property="author" size="40" maxlength="50"/></p></html:form></body></html:html>修改Struts-config.xml檔案：<form-beans>
<!-- DynaActionForm Bean for usesturts -->
<form-bean name="usestrutsForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="user" type="java.lang.String" />
<form-property name="password" type="java.lang.String" />
<form-property name="title" type="java.lang.String" />
<form-property name="content" type=" java.lang.String " />
<form-property name="author" type="java.lang.String" />
</form-bean>
</form-beans><!-- ========== Action Mapping Definitions ============================= -->
<action-mappings>
<!-- usersturts ActionForm ===================================== -->
<action path="/prepareUsestruts"
type="action.preUsestrutsAction">
<forward name="success" path="/jsp/useStruts.jsp"/>
</action>
<action path="/processUsestruts"
type="action.ProcessUseStrutsAction"
name="usestrutsForm"
scope="request"
input="/jsp/useStruts.jsp"

建立兩個Action：
