这次，到是CXF的SERVER和CLIENT都可以正常通信了。但我不说也知道啦，PERL又出问题了!

comet的实现介绍：这里

其中的原理在于维护HTTP长连接，这里有介绍

摘录一部分，说明其原理：

Pushlet基于HTTP流，这种技术常常用在多媒体视频、通讯应用中，比如QuickTime。与装载HTTP页面之后马上关闭HTTP连接的做法相反，Pushlet采用HTTP流方式将新数据源源不断地推送到client，再此期间HTTP连接一直保持打开。有关如何在Java中实现这种Keep-alive的长连接请参看Sun提供的《HTTP Persistent Connection》和W3C的《HTTP1.1规范》。
示例1
        我们利用HTTP流开发一个JSP页面（因为它易于部署，而且它在web server中也是作为servlet对待的），此页面在一个定时器循环中不断地发送新的HTML内容给client：

<% 
  int i = 1;
    
  try {
    while (true) {
       out.print("<h1>"+(i++)+"</h1>");
       out.flush();
      
       try {
            Thread.sleep(3000);
       } catch (InterruptedException e) {
       out.print("<h1>"+e+"</h1>");
        }
     }
   } catch (Exception e) {
       out.print("<h1>"+e+"</h1>");
   }
%>

  7: <% 
  8:   /** Start a line of JavaScript with a function call to parent frame. */
  9:   String jsFunPre = "<script language=JavaScript >parent.push('";
 10:   
 11:   /** End the line of JavaScript */
 12:   String jsFunPost = "')</script> ";
 13:   
 14:   int i = 1;
 15:   try {
 16:   
 17:     // Every three seconds a line of JavaScript is pushed to the client
 18:     while (true) {
 19:     
 20:        // Push a line of JavaScript to the client 
 21:        out.print(jsFunPre+"Page "+(i++)+jsFunPost);
 22:        out.flush();
 23:        
 24:        // Sleep three secs
 25:        try {
 26:             Thread.sleep(3000);
 27:        } catch (InterruptedException e) {
 28:             // Let client display exception 
 29:             out.print(jsFunPre+"InterruptedException: "+e+jsFunPost);
 30:        }
 31:      }
 32:    } catch (Exception e) {
 33:             // Let client display exception 
 34:             out.print(jsFunPre+"Exception: "+e+jsFunPost);
 35:    }
 36: %> 

<script LANGUAGE="JavaScript">
var pageStart="<HTML><HEAD></HEAD><BODY BGCOLOR=blue TEXT=white><H2>Server pushes: <para>";
var pageEnd="</H2></BODY></HTML>";
  // Callback function with message from server.
  // This function is called from within the hidden JSP pushlet frame
  function push(content) {
 
    // Refresh the display frame with the content received
    window.frames['displayFrame'].document.writeln(pageStart+content+pageEnd);
    window.frames['displayFrame'].document.close();
  }

</script>



     <!-- frame to display the content pushed by the pushlet -->
     
     
     <!-- Hidden frame with the pushlet that pushes lines of JavaScript-->
     
</FRAMESET>

<H1>WAIT...</H1>
