Re: Comet API Question
i'm catching the subevents but they don't get fired. i've a problem with this szenario: i need to reset some serverside variables when the user clicks the reload button in the browser with an active hanging get request. i therefore used the main END event for detection because the subevents don't work for better separation. this works fine when i'm not behind a proxy. but if i'm behind a proxy the END event is not fired (perhaps the proxy is still holding the connection?) do you have an idea what happens when there is a proxy between the server and the client and how i can reset the variables? kind regards, jens On 1/8/08, Filip Hanik - Dev Lists <[EMAIL PROTECTED]> wrote: > > yes, uncommenting that valve in context.xml should do the trick, is it > not firing or are you just not catching it? > > 2nd question, currently it just marks the request/response as non comet, > and then calls response.finishResponse(), this will write any left over > bytes to the socket. > > Filip > > Jens Hagel wrote: > > Hi, > > i need to detect if the user reloads the webapp or rather if the > connection > > gets interrupted. > > i therefore use the CometEvent.EventSubType but the events don't get > fired. > > in the context.xml i've uncommented the CometConnectionManagerValve. > > Do I have to instantiate the ConnectionManager by myself or what's going > > wrong? > > > > 2nd question: it's a little bit unclear to my what happens when i call > > cometEvent.close() > > sometimes i use it and sometimes not with no difference.. :) > > > > Kind regards, > > Jens > > > > > > > > > > No virus found in this incoming message. > > Checked by AVG Free Edition. > > Version: 7.5.516 / Virus Database: 269.17.11/1201 - Release Date: > 12/28/2007 11:51 AM > > > > > - > To start a new topic, e-mail: users@tomcat.apache.org > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > >
Comet API Question
Hi, i need to detect if the user reloads the webapp or rather if the connection gets interrupted. i therefore use the CometEvent.EventSubType but the events don't get fired. in the context.xml i've uncommented the CometConnectionManagerValve. Do I have to instantiate the ConnectionManager by myself or what's going wrong? 2nd question: it's a little bit unclear to my what happens when i call cometEvent.close() sometimes i use it and sometimes not with no difference.. :) Kind regards, Jens

Re: Comet: response.sendRedirect() Problem
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

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?
