我的主要工具：tomcat+eclipse
第一个：struts标签如何写，我写了一个，但是页面显示出来的空白，程序如下:
<%@page contentType="text/html;charset=GB2312"language="java"%>
<%@taglib uri="/WEB-INF/struts-bean.tld"prefix="bean"%>
<%@taglib uri="/WEB-INF/struts-html.tld"prefix="htem"%>
<%@taglib uri="/WEB-INF/struts-logic.tld"prefix="logic"%>
<%@taglib uri="/WEB-INF/struts-template.tld"prefix="template"%>
<html:html>
<head><title>simple struts!</title></head>
<body bgColor=white>
<html:base/><html:form method="post" action="/HelloWorldAction.do">
<html:text property="mybeanvariabled"/><html:submit value="enter"/>
<html:reset value="reset"/>
</html:form>
</body>
</html:html>
第二个：actionservlet如何启动呢?
web.xml是这样定义的
<?xml version="1.0"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">

<web-app>
<!-- Action Servlet Configuration -->
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
  <init-param>
    <param-name>debug</param-name>
    <param-value>2</param-value>
  </init-param>
<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>

<!-- Action Servlet Mapping -->
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

<!-- The Welcome File List -->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- Struts Tag Library Descriptors -->
<taglib>
<taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri>
<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>/WEB-INF/struts-html.tld</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>

<taglib>
<taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri>
<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
</taglib>
<taglib>
  <taglib-uri>/WEB-INF/struts-template.tld</taglib-uri>
  <taglib-location>/WEB-INF/struts-template.tld</taglib-location>
</taglib>
</web-app>
struts-config.xml的配置如下：
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.0//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd">
<struts-config>
<form-beans>
<form-bean name="HelloWordForm"type="HelloWordForm" />
</form-beans>
<action-mappings>
<action path="/HelloWordAction"
type="HelloWordAction"
name="HelloWordForm"
scope="session"
input="/HelloWord.jsp">
<forward name="success" path="/out.jsp" />
<forward name="failure" path="error.jsp"/>
</action>
</action-mappings>
</struts-config>
问题如下：tomcat启动过程中一切正常，但是一旦要进入一旦传送HelloWorldAction.do系统提示错误：servlet is not avariable！
请问这到底是什么原因造成的呢？我都是按照网上的实例来配置的，为什么还会出现这样的问题呢？

<html:form method="post" action="/HelloWorldAction.do">里面的"/HelloWorldAction.do" 改成"/HelloWordAction"试试。要和path="/HelloWordAction" 里面的对应
