使用了:pushlet 2.0.4 + Extjs4.0.2 服务器:tomcat6.0+

偶前几也弄了一下，想用Pushlet做一个向客户端广播消息的功能：比如管理员发布一个消息后，所有建立了长连接的客户端将实时的收到这个消息。但做的时候碰到个问题如下.不知楼主是否碰到，望赐教
hi,jounne
i previewed that your discussion on chrome'issue about pushlets comet
technology.
At last you say "Content-Type: application/octet-stream" will work。But it
does not work for me.
So , i write to u for help.
my problems as follows:
I use pushlets created a long connection to request a method to get some
infos via this long connection
without refresh my page. it works very well on firefox but what a big pity
on chrome.
The detail is that, after i send the request via firefox client, i
monitored the long connection is effective with firebug,
i received data bit by bit from server; but this state disappear into thin
air when i use chrome client,
the chrome can create connection too, but the connection is not long
connection, i monitored that the request was growing.
it is one request one response。
my code as follows:
JavaCode
static public class SystemStatusEventPullSource
extends EventPullSource {
Runtime runtime = Runtime.getRuntime();
public long getSleepTime() {
return 1000;
}
public Event pullEvent() {
Event event =
Event.createDataEvent("/system/jvm");
event.setField("已申请到的内存", "" +
runtime.totalMemory());
event.setField("空闲内存", "" +
runtime.freeMemory());
event.setField("可申请分配的内存", "" +
runtime.maxMemory());
int activeCount = Thread.activeCount();
event.setField("threads", "" +
activeCount);
return event;
}
}
ClientCode
<script
type="text/javascript">
//
Initialization
function init() {
p_join_listen('/system/jvm');
}
// Event Callback: display all events
function onEvent(event) {
document.eventDisplay.EVENT.value =
event.toString();
}
</script>
Finally, i modified the pushlets source code follow your workaround.
BrowserAdapter.java
Line 42
servletRsp.setContentType("text/html;charset=UTF-8");
TO
servletRsp.setContentType("application/octet-stream");
that is all.
Best wishes!

另外一个问题是我在pullEvent()方法中如何获取到登录用户的回话信息啊？

做长连接可以试试NodeJS做服务器端，socket.io做客户端连接。

楼主，发布代码是删掉某些东西了。不能多用户在线
