Comet: response.sendRedirect() Problem
Hello,
I'm trying to use the sendRedirect() function in the begin event of a
simple CometServlet,
but nothing happens. Does anyone has an idea what's going wrong?
kind regards,
jens hagel
------------------
import org.apache.catalina.CometProcessor;
import org.apache.catalina.CometEvent;
import javax.servlet.http.*;
import javax.servlet.ServletException;
import java.io.IOException;
public class CometServlet extends HttpServlet implements CometProcessor {
public void event(CometEvent cometEvent) throws IOException,
ServletException {
HttpServletResponse response = cometEvent.getHttpServletResponse();
// don't want timeout events
cometEvent.setTimeout(1000000);
if (cometEvent.getEventType() == CometEvent.EventType.BEGIN) {
log("Begin for session");
response.sendRedirect("http://www.heise.de");
cometEvent.close();
} else if (cometEvent.getEventType() == CometEvent.EventType.ERROR) {
log("Error for session: " + cometEvent.getEventSubType());
cometEvent.close();
} else if (cometEvent.getEventType() == CometEvent.EventType.END) {
log("End for session");
cometEvent.close();
} else if (cometEvent.getEventType() == CometEvent.EventType.READ) {
log("Read for session");
}
}
}

hi Jens,
you've uncovered a bug in Tomcat. basically, Tomcat doesn't respect that
you are calling CometEvent.close upon the BEGIN event.
I've proposed a fix
http://svn.apache.org/viewvc?view=rev&revision=594957
and if it is accepted it will be included in our next release which
should be within a short timeframe.
if you want to patch your Tomcat, the patch is at
http://people.apache.org/~fhanik/patches/comet-begin-event-close.patch

hi,
i'm implementing comet support for different servlet containers in an
ajax framework.
with jetty and glassfish comet support it works very well, but with
tomcat something
is going wrong with the Servlet API sendRedirect()- function which i
cannot figure out.
do you have an idea what's going wrong?
thank you!
regards,
jens

there is a bug in 6.0.14 regarding pipelining HTTP events on a comet
connection, your code is correct, try with our current release candidate
http://people.apache.org/~remm/tomcat-6/v6.0.15/bin/
