Dears,
My PC environment are windows XP professional Version 2002 Service Pack 3,
JDK1.6, Tomcat7.0.30.
my Java web project is an internet online chat-room based on websocket. I run
the local-host service in Tomcat and then connect my chat-room in chrome,
if the connection between server and browser is OK, the websocket client side
function onopen() will pop up a message "open".
But, the point is if I open several pages at same time, I can see all of
pages pop up the message "open", it means every connection of page to server is
OK.
but when I try to send some words to server, The server has no response ( in
the other word, the server side function onTextMessage() is not called),
it happen in part of the pages not all of them. I would like to know if you
encounter the same problem.
Excuse me, the second question: how to set the maximum idle time of
connection of websocket.
The set up in server.xml does not work:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="5000"
redirectPort="8443" />
<!-- A "Connector" using the shared thread pool-->
<!--
<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="5000"
redirectPort="8443" />
-->
These is part of the client side code:
function startWebSocket() {
if ('WebSocket' in window)
{ws = new WebSocket("ws://localhost:8080/MyWebSocket/mywebsocket.do");
}
else if ('MozWebSocket' in window)
{ws = new
MozWebSocket("ws://localhost:8080/MyWebSocket/mywebsocket.do");
}
else
alert("not support");
ws.onmessage = function(evt) {
alert(evt.data);
};
ws.onopen = function(evt) {
alert("open");
};
ws.onclose = function(evt) {
alert("close");
};
}
And part of the server side code:
public class MyMessageInbound extends MessageInbound {
@Override
protected void onBinaryMessage(ByteBuffer arg0) throws IOException {
// TODO Auto-generated method stub
}
@Override
protected void onTextMessage(CharBuffer msg) throws IOException {
System.out.println(msg.toString());
for (MessageInbound messageInbound : InitServlet.getSocketList()) {
WsOutbound outbound = messageInbound.getWsOutbound();
CharBuffer buffer = CharBuffer.wrap(msg);
outbound.writeTextMessage(buffer);
outbound.flush();
}
}
@Override
protected void onClose(int status) {
InitServlet.getSocketList().remove(this);
super.onClose(status);
System.out.println(getTime()+" connection is closed");
}
@Override
protected void onOpen(WsOutbound outbound) {
super.onOpen(outbound);
InitServlet.getSocketList().add(this);
System.out.println(getTime()+" connection is open");
}
public String getTime(){
Date now = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd
HH:mm:ss");
String NowTime = dateFormat.format( now );
return NowTime;
}
}
I would eagerly look forward to your reply.
