Struts html标签不起作用

Question

Struts html标签不起作用

Ram*_*mis 5 struts-1

我只是尝试在带有struts提供标签的jsp页面中包含一个文本框.但它表现得很典型.

工作

<html:text property="name" value=""></html:text>

不工作

<html:text property="name"></html:text>
因此,没有财产'value',它不起作用.请帮帮我们.

注意:使用tomcat 6.0
bean,逻辑工作正常,在html中也大部分工作正常.无线电,textarea,文本是导致问题的一些.
JSP文件

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

的<html:text>标签被认为的内侧被封闭<html:form>标签,它定义的动作,并且因此在ActionForm实例从中<html:text>获取其值.
