<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE Struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/Struts/dtds/Struts-config_1_1.dtd";>
<!--
This is the Struts configuration file for the example application, using the proposed new syntax.
-->
<Struts-config>

<!-- ========== Form Bean Definitions =================================== -->
<!-- FormBean是Struts的一个概念，本质是JavaBean，用来自动存储页面表单中各个域的值，并在适当的时候回填表单域，不需要象传统那样request.getParameter("fieldName");，常被action-mappings中的action 使用 -->
<form-beans>
<!-- 稍后我们会新增一个GetparameterForm类，用来存储用户信息 -->
<form-bean name="GetParameterForm" type="beans.GetParameterForm"/>
</form-beans>

<!-- ========== Global Forward Definitions ============================== -->
<!--这里存放整个系统都可以使用的全局转向中转(Forward)地址 -->
<!-- 一般情况下，一个Action处理完毕后，会转发到一个JSP页面进行显示。这也是JSP中的MVC的实现的要点。-->
<global-forwards>
<!--failed.do和success.do将被当成servlet请求，到action-mappings中寻找对应的action处理。-->
<forward name="success" path="/success.do"/>
<forward name="fail" path="/fail.do"/>
</global-forwards>

<!-- ========== Action Mapping Definitions ============================== -->
<!--web.xml中后缀为.do的请求被转到这里处理。这里相当于Struts的Model部分，Model部分是Struts中比较灵活的地方。-->
<action-mappings>
<!--处理showinput.do的请求，使用的FormBean是GetparameterForm，既beans.GetParameterForm类，当处理过程发生错误时将返回index.jsp-->
<action path="/showinput" type="beans.ShowAction" name="GetParameterForm" scope="request" input="/index.jsp" />
<action path="/success" forward="/success.jsp"/>
<action path="/fail" forward="/error.jsp" />
</action-mappings>

</Struts-config>

web.xml如下:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<display-name>Struts AddressBook Sample Applications</display-name>
<servlet>
<servlet-name>beans.GetParameterForm</servlet-name>
<servlet-class>beans.GetParameterForm</servlet-class>
</servlet>
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<servlet-mapping>
<url-pattern>/beans/GetParameterForm.class</url-pattern>
<servlet-name>beans.GetParameterForm</servlet-name>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

index.jsp如下:
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.util.*,java.sql.*,java.text.*,java.io.*"%>
<html>
<form name="form1" method="post" action="showinput.do">
输入success将返回到"success"页面，否则返回到"fail"页面<br><br>
input:<input type="text" name="valu">　　<input type="submit" value="submit">
</form>
<br>
<a href="success.do">success</a><br>
<a href="fail.do">fail</a>
</html>

不管是输入点提交,还是直接点链接都提示
The requested resource (Servlet action is not available) is not available

1.<action path="/showinput" type="beans.ShowAction" name="GetParameterForm" scope="request" input="/index.jsp" />
改为<action path="/showinput" type="beans.ShowAction" name="GetParameterForm" attribute="GetParameterForm" scope="request" input="/index.jsp" />

2. <form name="form1" method="post" action="showinput.do">
改为<form method="post" action="showinput.do">

3. 看看Struts的包都导进项目了吗

<action-mappings>
<action
attribute="GetParameterForm"
path="/showinput"
type="beans.ShowAction"
scope="request"
input="/index.jsp" />
<action path="/success" forward="/success.jsp"/>
<action path="/fail" forward="/error.jsp" />
</action-mappings>

action应该这样写！还有就是注意你jsp的文件位置，否则出现找不到文件错误！

<form name="form1" method="post" action="/showinput.do">改为！
