1.编写一个JavaBean

UserBean.java

package com.cn.zhb; public class UserBean { private String name; private String password; public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

2.配置WEB.XML文件

  <?xml version="1.0" encoding="ISO-8859-1"?>  
 <web-app xmlns="http://java.sun.com/xml/ns/j2ee"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"   
    version="2.4">  
  
    <description>  
        JSF Demo   
    </description>  
    <display-name>JSF Demo</display-name>  
    <servlet>  
        <servlet-name>Faces Servlet</servlet-name>  
        <servlet-class>  
            javax.faces.webapp.FacesServlet   
        </servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
  
    <servlet-mapping>  
        <servlet-name>Faces Servlet</servlet-name>  
        <url-pattern>*.faces</url-pattern>  
    </servlet-mapping>   
  
    <welcome-file-list>
  <welcome-file>index.faces</welcome-file>
  </welcome-file-list>

 </web-app>

3.在WEB-INF下定义faces-config.xml

<?xml version="1.0"?> <!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN" "http://java.sun.com/dtd/web-facesconfig_1_0.dtd"> <faces-config> <navigation-rule> <from-view-id>/pages/index.jsp</from-view-id> <navigation-case> <from-outcome>login</from-outcome> <to-view-id>/pages/welcome.jsp</to-view-id> </navigation-case> </navigation-rule> <managed-bean> <managed-bean-name>user</managed-bean-name> <managed-bean-class>com.cn.zhb.UserBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> </faces-config>

4.编写index.jsp页面

<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <%@page contentType="text/html;charset=UTF-8"%> <html> <head> <title>JSF</title> </head> <body> <f:view> <h:form> NAME: <h:inputText value="#{user.name}" /> PASSWORD:<h:inputSecret value="#{user.password}"></h:inputSecret> <p> <h:commandButton value="LOGIN" action="login" /> </h:form> </f:view> </body> </html>

5.welcom.jsp

<STRONG><%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <%@page contentType="text/html;charset=UTF-8"%> <html> <head> <title>JSF</title> </head> <body> <f:view> name:<h:outputText value="#{user.name}" /> <br> password:<h:outputText value="#{user.password}" /> <br> <h3> JavaServer Faces！ </h3> </f:view> </body> </html> </STRONG>
