1.开发环境
   与Eclipse下Struts的开发类似，安装好Eclipse和Tomcat之后，还需要两个插件：tomcat 插件和JSF插件（如果相关插件还没有安装），以下是相关下载地址：
    Eclipse SDK：
        http://www.eclipse.org/downloads/index.php 
    JSF:
     https://sourceforge.jp/projects/amateras/files/  
      FaceIDE+htmlEditor，htmlEditer也是必要的
    Tomcat :
         http://www.sysdeo.com/eclipse/tomcatplugin 
    Plugin Search:
         http://eclipse-plugins.2y.net/eclipse/search.jsp 
   插件的安装和配置有问题请直接Google。
2.开始
    入门嘛，我们就找一个最简单的Login就可以了

    新建Tomcat project
    加入JSF支持

    新建一个ManagedBean：


/**
 *
 */
package com.jsf;




/**
 * @author lzy
 *
 */
public class UserBean {
private String name;
    private String password;
public String verify() {
     if(this.name.equals("name")&&this.password.equals("password"))
     
        return "failure";

   else
        return "success";
}

 
/**
* @return Returns the name.
*/
public String getName() {
return name;
}

/**
* @param name The name to set.
*/
public void setName(String name) {
this.name = name;
}


/**
* @return Returns the password.
*/
public String getPassword() {
return password;
}

/**
* @param password The password to set.
*/
public void setPassword(String password) {
this.password = password;
}


}

     新建两个JSP页面，login.jsp,welcom.jsp

login.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
<head>
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
<head>
<link href="main.css" rel="stylesheet"/>
<title></title>

</head>
<body>
    <f:view>
    <f:loadBundle basename="com.jsf.MessageResources" var="msgs"></f:loadBundle>
   
        <h:form>
        <h:panelGrid columns="3" headerClass="header" rowClasses="evenRow,oddRow">
        <f:facet name="header" >
        <h:outputText value="#{msgs.header}"/>
        </f:facet>
       
        <h:outputText value="#{msgs.namePromt}"></h:outputText>
        <h:inputText id="name"  required="true" value="#{user.name}">
        <f:validateLength minimum="2" maximum="10"></f:validateLength>
        </h:inputText>
        <h:message for="name" errorClass="errors"/>
       
       
        <h:outputText value="#{msgs.passwordPromt}"></h:outputText>
       
        <h:inputSecret id="password" value="#{user.password}" required="true" redisplay="true">
        <f:validateLength minimum="2"></f:validateLength>
        </h:inputSecret>
        <h:message for="password"/>
       
       
              <f:facet name="footer" >
        <h:outputText value="#{msgs.footer}"/>
        </f:facet>
        </h:panelGrid>          
            <h:commandButton value="#{msgs.submitPromt}" action="#{user.verify}"/>
            <h:commandButton value="#{msgs.resetPromt}" type="reset"/>
        </h:form>
    </f:view>
</body>
</html>



welcome.jsp


<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK"/>
<title></title>
</head>
<body>
    <f:view>
        <h:outputText value="#{user.name}"/>  is a good boy！
        <h3>welcome JavaServer Faces</h3>
    </f:view>
</body>

</html>
     编辑WEB－INF/lib下的faces－config.xml

struts-config.xml

<?xml version="1.0"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config>
<navigation-rule>
        <from-view-id>/login.jsp</from-view-id>
        <navigation-case>
            <from-outcome>success</from-outcome>
            <to-view-id>/welcome.jsp</to-view-id>
        </navigation-case>
        <navigation-case>
            <from-outcome>failure</from-outcome>
            <to-view-id>/login.jsp</to-view-id>
        </navigation-case>
</navigation-rule>


<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>com.jsf.UserBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
</faces-config>


       最后是资源文件

# --login.jsp--
header=Welcom
namePromt=Name:
passwordPromt=Password:
amountPromt=Amount:
datePromt=Date:
submitPromt=Submit
resetPromt=Reset
footer=Thank you!


3.测试
在test工程中选择tomcat project－>Update context definition
然后运行Tomcat
http://127.0.0.1:8080/jsfTest/login.jsf
