Answer 1

struts学习中！！！！！！！！！！1

Answer 2

看看struts的例子就OK 了啊我试过了没问题的

Answer 3

validateLoginForm()应是validateLoginform()

Answer 4

我也用过一次ValidatorForm也出错了
用DynaValidatorForm就不会出错------------------------------
配置如下:
<?xml version="1.0" encoding="UTF-8"?>
<!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>  <form-beans>
    <!--配置动态表单checkoutForm-->
    <form-bean name="checkoutForm" type="org.apache.struts.validator.DynaValidatorForm">
      <form-property name="name" type="java.lang.String" />
      <form-property name="address" type="java.lang.String" />
      <form-property name="city" type="java.lang.String" />
      <form-property name="postalCode" type="java.lang.String" />
      <form-property name="country" type="java.lang.String" />
      <form-property name="phone" type="java.lang.String" />
    </form-bean>
  </form-beans>
  <action-mappings>
    <action  name="checkoutForm" input="/index.jsp" path="/processcheckout" validate="true" type="validatorframe1.ProcessCheckoutAction">
      <forward name="Success" path="/info.jsp">
      </forward>
      </action>
  </action-mappings>
 <message-resources parameter="ApplicationResources">
 </message-resources>
 <!--使用动态验证插件-->
  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
    <set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />
  </plug-in>
</struts-config>

Answer 5

在validation.xml代码：里
 property="userName "这错误，userName后面多了一个空格

Answer 6

我仔细看了一下代码，错误可能在这里
在struts-config.xml代码：中
========
    <form-beans>
        <form-bean name="loginform" type="LoginForm"/>        
    </form-beans>
========
应该这样：=
    <form-beans>
        <form-bean name="loginform" type="LoginForm"/>        
         <form-property name="userName" type="java.lang.String"/> //这段代码应该加上
    </form-beans>

Answer 7

我知道了，你得struts的版本不对，不能用myeclipse自己带的，我用strut1.2.7就可以了
