Configuring two connectors and COMET Read event
Hi,
I am developing an alication where i need two servlets.
One is a normal Http Servlet and another is a comet servlet.
Now i also need two connectors to be setup in server.xml.
One is a normal HTTP/1.1 connector and another a NIO connector.
I made changes to the server.xml as follows.
server.xml
=
Connector port=8080 protocol=HTTP/1.1
connectionTimeout=2
redirectPort=8443 /
Connector port=8081
protocol=org.apache.coyote.http11.Http11NioProtocol
connectionTimeout=2 redirectPort=8444 /
Connector port=8009 protocol=AJP/1.3 redirectPort=8443 /
=
web.xml
servlet
servlet-namecometServlet/servlet-name
servlet-classcom.mycomet.servlet.CometControllerServlet/servlet-class
/servlet
servlet-mapping
servlet-namecometServlet/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
=
I have a simple comet servlet as follows.
public class CometControllerServlet extends HttpServlet implements
CometProcessor{
@Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
}
@Override
public void event(CometEvent event) throws IOException,
ServletException {
HttpServletRequest request = event.getHttpServletRequest();
HttpServletResponse response = event.getHttpServletResponse();
if (event.getEventType() == EventType.BEGIN) {
System.out.println(In begin );
}
if (event.getEventType() == EventType.READ) {
System.out.println(In read);
}
if (event.getEventType() == EventType.END){
System.out.println(event.getEventSubType());
System.out.println(In end);
}
if (event.getEventType() == EventType.ERROR){
System.out.println(In error);
}
}
}
=
Now my questions are:
1. can i define two connectors the way as mentioned above?
The purpose is top provide noth a NIO connector for comet clients and a
normal connector for normal clients.
2. I am not able to invoke the READ event. How do i do that?
3. Can i send two HTTP request over the same NIO connection. So in effect
for a client on a sinle connectionthere is one BEGIN event and two read
events.
Is it possible in COMET?
Thanks,
Animesh.

From: Animesh Sonkar [mailto:akson...@gmail.com] Subject: Configuring two connectors and COMET Read event Now i also need two connectors to be setup in server.xml. Why do you think that? One is a normal HTTP/1.1 connector and another a NIO connector. Why not just the NIO connector? 1. can i define two connectors the way as mentioned above? Yes, but it's probably pointless. The purpose is top provide noth a NIO connector for comet clients and a normal connector for normal clients. Again, why? Let them both use the NIO connector to avoid having to switch ports on redirects and the like. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

If you happen to be using an HttpURLConnection, call setChunkedStreamingMode( 1 ). If you are taking a lower level approach, (i.e. using sockets), send a header Transfer-Encoding: chunked, and send CRLF and flush your stream between chunks. *snip* Thanks, Animesh. -- Stephen Byrne step...@lincware.com (585) 286-5817 - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
