JSF Bean Servlet Java SUN

1.定义一个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.web.xml配置

<?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下定义一个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

<%@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.编写welcome.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>

OK，大功告成
