Richfaces 4.1和a4j：推送：如何讓它工作？

是否有人在我的環境中使用a4j：push標籤功能？Richfaces 4.1和a4j：推送：如何讓它工作？

RichFaces的4.1決賽
MyFaces的2.1.5
氣氛0.83
的Tomcat 7.0.23

任何建議都非常歡迎。

感謝，米洛的van der Zee的

這是我的測試：

的web.xml（編輯：固定）：

...

TestPushBean.java：

package com.vetmanager.base.test; 

import java.text.SimpleDateFormat; 
import java.util.Calendar; 

import javax.faces.bean.ManagedBean; 
import javax.faces.bean.SessionScoped; 

import org.apache.log4j.Logger; 
import org.richfaces.application.push.MessageException; 
import org.richfaces.application.push.TopicKey; 
import org.richfaces.application.push.TopicsContext; 

/** 
* 
*/ 
@ManagedBean 
@SessionScoped 
public class TestPushBean { 
    private static final Logger LOGGER = Logger.getLogger(TestPushBean.class.getName()); 

    private static final TopicKey TOPIC_KEY = new TopicKey("push"); 

    /** 
    * Constructor init's the topic. 
    */ 
    public TestPushBean() { 
     LOGGER.debug("TestPushBean"); 

     TopicsContext topicsContext = TopicsContext.lookup(); 
     topicsContext.getOrCreateTopic(TOPIC_KEY); 
    } 

    /** 
    * @return String 
    */ 
    public String getNow() { 
     LOGGER.debug("getNow"); 

     Calendar now = Calendar.getInstance(); 
     SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MMM-yyyy/HH:mm:ss"); 
     return dateFormatter.format(now.getTime()); 
    } 

    /** 
    * 
    */ 
    public void push() { 
     LOGGER.debug("push"); 

     TopicsContext topicsContext = TopicsContext.lookup(); 
     try { 
      topicsContext.publish(TOPIC_KEY, "Test String"); 
     } catch (MessageException e) { 
      LOGGER.error("push: " + e, e); 
     } 
    } 
}
