The problem of the binding a UIcomponent ...

Question

Hi.here
The problem of the binding a UIcomponent I met.
there are some codes of the login.jsp:
<h:form>
userName:<h:inputText id="userid" binding="#{Login.userid}" required="true"></h:inputText>
password<h:inputSecret id="password" binding="#{Login.password}" required="true"></h:inputSecret><br>
<h:commandButton value="’ñŒð" action="#{Login.Login_Checked}"></h:commandButton>
</h:form>
-----------faces-config.xml--------------------------
<managed-property>
<property-name>userid</property-name>
<property-class>javax.faces.component.html.HtmlInputText</property-class>
<value>userid</value>
</managed-property>
<managed-property>
<property-name>password</property-name>
<property-class>javax.faces.component.html.HtmlInputSecret</property-class>
<value/>
</managed-property>
When I was running the page,the Exeption came out! As following:
javax.servlet.ServletException: Error performing conversion of value userid of type class java.lang.String to type class javax.faces.component.html.HtmlInputText for managed bean Login._
javax.faces.webapp.FacesServlet.service(FacesServlet.java:249)_
Can you help me?

I hava do ii as you say . Now I give you the javaBean code:
package com.jsfdemo;
import javax.faces.component.html.HtmlInputSecret;
import javax.faces.component.html.HtmlInputText;
* @author Administrator
public class Login {
     private HtmlInputText userid;
     private HtmlInputSecret password;
     public Login() {
     public HtmlInputText getUserid() {
          return userid;
     public void setUserid(HtmlInputText userid) {
          this.userid = userid;
     public HtmlInputSecret getPassword() {
          return password;
     public void setPassword(HtmlInputSecret password) {
          this.password = password;
     public String Login_Checked()
*          try{*
*               if(userid.getValue().equals("myeclipse")&& password.getValue().equals("myeclipse"))*
*               return "success";*
*          else*
*               return "failure";*
*          catch(NullPointerException e)*
*               System.out.println("exception: " + e.getMessage());*
*               return "failure";*
Is it this?
