Struts问题：Attribute name invalid for tag form according to TLD

如何判断是否一样？我是把struts1.2.4目录下的struts-html.tld拷贝到我的WEB-INF目录下的，index.jsp里代码是：
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>

/index.jsp(34,1)
你的34行是什么？

标签的属性名肯定是写错了。
看一下struts-html.tld里面是怎么写的，要对上。
写错的那个标签就在index.jsp的34行。

34行就是：
<html:form action="Lookup" name="lookupForm" type="wiley.LookupForm">struts-html.tld内容很多，要和哪个对上？刚接触struts，不好意思

这些是从struts-html.tld中提取出来的，好像没有name属性啊！
需要怎么该呢？
<tag>
<name>form</name>
<tagclass>org.apache.struts.taglib.html.FormTag</tagclass>
<bodycontent>JSP</bodycontent>
<attribute>
<name>action</name>
<required>true</required>

<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>

<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>

<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>
<name>target</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>

既然tld没有定义，就不能写
把name="lookupForm"删掉

删掉以后就找不到FormBean了，错误如下

你的formbean要在struts-config.xml和jsp页面上定义的。

定义过的
struts-config.xml
------------------
<?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"><struts-config>
<message-resources parameter="wiley.ApplicationResources"/>
<form-beans>
<form-bean name="lookupForm" type="wiley.LookupForm"/>
</form-beans>
<action-mappings>
<action path="/Lookup"
type="wiley.LookupAction"
name="lookupForm"
input="/index.jsp">
<forward name="success" path="quote.jsp">
<forward name="failure" path="index.jsp">
</action-mappings>
</struts-config>index.jsp
----------------------------
<%@page language="java"%>
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
...
<html:form action="Lookup" name="lookupForm" type="wiley.LookupForm">
<table width="45%" border="0">
<tr>
<td>Symbol:</td>
<td><html:text property="symbol" /></td>
</tr>
<tr>
<td colspan="2" align="center"><html:submit/></td>
</tr>
</table>
</html:form>
...

1、你的<html:form action="Lookup" name="lookupForm" type="wiley.LookupForm">
修改成<html:form action="/Lookup">2、在你的action path里面加上这个formbean的有效范围，scope="request"。
<action path="/Lookup"
type="wiley.LookupAction"
name="lookupForm"
         scope="request"
input="/index.jsp">
  <forward name="success" path="quote.jsp">
  <forward name="failure" path="index.jsp">
</action>

<html:form action="Lookup" name="lookupForm" type="wiley.LookupForm">
把这里的name和type去掉试一下

chubbchubb(长街) 和ecaol(孤单北半球)：你们的方法我试过了，结果都是
...
javax.servlet.ServletException: Cannot find ActionMappings or ActionFormBeans collection
...就是第二次贴的那个错误信息
:(
是不是struts版本的问题啊，我用的是sturts1.2.4
书上的例子是struts1.1的
1.2.4中action标签没有name和type属性
1.1的我下载不到，不知道是不是有<html:form action="Lookup" name="lookupForm" type="wiley.LookupForm">
<html:form action="Lookup" >
<html:form action="/Lookup" >
<html:form action="Lookup.do">
都试过了，都不行！
第一中情况结果是：Attribute name invalid for tag form according to TLD
后面三种情况结果是：ActionMappings or ActionFormBeans 我在struts-html.tld中加上name属性，运行错误是name没有setter方法，看来struts的action标签中确实没有name属性
郁闷中...

能否给一个可以运行的实例参照一下(Struts1.2.4的)，

Struts1.2.4的例子，在他的src文件包里就有，不用另找。
