[页面加载时异常]javax.servlet.ServletException: Exception creating bean of class org.com.jing.web.form: {1}

Question

　　请问这是什么原因啊，这在网上看了有的说是标签的问题，有的说是FormBean里面对应界面的<html:/>没有getter方法，我都检查过了，都没有问题，配置文件里面也看过没有问题

Answer 1

PageContextImpl.java:848
PageContextImpl.java:781
检查一下这两行,肯定有问题

Answer 2

然后你再检查一下你的JSP页面

Answer 3

将你的formbean代码和jsp贴出来看看

Answer 4

public class LoginFrom extends ActionForm {
private static final long serialVersionUID = 9219877607080071331L;
private String username;
private String userpassword;

public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getUserpassword() {
return userpassword;
}
public void setUserpassword(String userpassword) {
this.userpassword = userpassword;
}
public LoginFrom() {
super();
}
@Override
public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
super.reset(mapping, request);
}
@Override
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
// TODO Auto-generated method stub
return super.validate(mapping, request);
}
}

<html:form action="userAction.do"  >&nbsp; 
      <input type="hidden" name="opType">
    <p/>
    <table align="center" bgcolor="#CCCCCC" cellpadding="0" cellspacing="0" border="1"  width="88%" style="border-color:#6600cc">
    <tr  style="border-color:#6600cc">
    <td align="right" width="50%"><font size="2">用户名：</font></td>
    <td><html:text property="username" size="10" /><div style="display:none" id="uname"><font size="2" color="red">请输入用户名！</font></div></td>
    </tr>
    <tr style="border-color:#6600cc">
    <td align="right"><font size="2">密&nbsp;&nbsp;码：</font></td>
    <td><html:password property="userpassword" size="10" /><div style="display:none" id="password"><font size="2" color="red">请输密码！</font></div></td>
    </tr>
    <tr style="border-color:#6600cc">
    <td colspan="2" align="center"> <html:button property="" value="登 陆" onclick="javascript:doSubmit('doLogin')"/></td>
    </tr>
    </table>
    </html:form>

Answer 6

<form-bean name="loginFrm" type="org.com.jing.web.form">
   <form-property name="username" type="string"/>
   <form-property name="userpassword" type="string"/>
   </form-bean> <action path="/userAction"
   attribute="loginFrm"
   name="loginFrm"
   input="/login.jsp"
   parameter="opType"
   scope="request"
   type="org.springframework.web.struts.DelegatingActionProxy">
   <forward name="index" path="/index.jsp"/>
   </action>

Answer 7

看着没什么问题，把在strtus-config.xml文件中配置这个form和action的代码也贴出来吧

Answer 8

<form-bean name="loginFrm" type="org.com.jing.web.form"> 
  <form-property name="username" type="string"/> 
  <form-property name="userpassword" type="string"/> 
  </form-bean> 
这里配置错误了
应该是
<form-bean name="loginFrm" type="org.com.jing.web.form.LoginFrom"></form-bean> 要具体到类名

Answer 9

我看了你的，错误的确很像，但是我还是没有找出来。有谁帮我解答一下。http://topic.csdn.net/u/20110724/21/5e10526d-10f6-4088-8428-078a32b7abd7.html?seed=1891453236&r=74577752#r_74577752
