Session timeouts: ignore periodic polling URL?
Hi, We have a Servelts/JSP application Tomcat6. Our javascripts issues automatic, periodic polling requests (Ajax and Comet), in order to keep the view up-to-date. Unfortunately this prevents sessions from timing out... Is there a way to tell Tomcat that some URL shouldn't affect session timeouts? Namely if for the last 30 minutes, the browser requested nothing but http://server/autoRefresh.do; , then Tomcat should assume the user went away from the computer, and kill the session. Thanks :)

Re: Installing Tomcat the Brute Force Way?
Robinson, Eric wrote: From looking at the server, it would appear that tomcat was installed using tomcat-6.0.18-0.noarch.rpm. Now you're in trouble. The 3rd-party repackaged versions of Tomcat typically scatter files all over, and then try to get things back together with symlinks. You're better off doing a proper install on the new server. Had you used a real Tomcat, life would be much easier. - Chuck Not necessarily. I did an rpm -qlp on tomcat-6.0.18-0.noarch.rpm. All the files it installs are in /opt/tomcat The files, yes. But it is highly likely that it installs also links from /etc/tomcat, /usr/share/tomcat, /usr/lib/tomcat, /var/lib/tomcat and so on. At least, that is what most Linux packages that I know are doing. To take a top-down view, you generally have two major choices : A) you download and install the real tomcat from tomcat.apache.org. That one installs everything below one top directory. It is easy to install, copy, update, etc.. * on its own *. If your purpose is mainly Tomcat-centric (e.g. you want to test Tomcat or develop for Tomcat, you have only this one server where you need to take care of it etc..), then that is probably the easiest solution. It is also easier to get support on this list, because with that one, everyone knows where to look for the files. And, that is also the right one to use of you want the very latest version available. OR B) you go with whatever package manager system is used by the target server, and use whatever best version they've got. As Chuck says, these packages have a tendency to spread files and links all over, if you look at it from a purely Tomcat point of view. But if you have to manage a bunch of servers, and Tomcat is only one little part in what you have to manage, and/or you need Tomcat to interact with other software packages which need to be of compatible versions etc.., then packages are definitely easier. I personally find it rather sweet to be able, on a new Debian Linux system fresh out of the box : - apt-get install sun-jdk6 - apt-get install apache2 - apt-get installl tomcat6 - apt-get install apache2-mod-jk (more or less) and have it all just work, and have it all put its startup scripts where (as a sysadmin) you expect (/etc/init.d), its logfiles where you expect them (/var/log/apache2 and /var/log/tomcat6) (and they get rotated too), its configuration files where you expect them (/etc/apache2 and /etc/tomcat6), and so on. It gets a little bit more puzzling when it comes time to figure out where (or if) it has installed the demo webapps though, or where exactly to find Tomcat's startup.sh, and whether the system is using it or not.. But you have a choice, and that's the nice part. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I 'm asking this for any tomcat version, starting with 5.x, 6.x or 7.x ... I don't care.

There are reasons why the web-app class loader and commons loader are not the same. Only the developer can really decide if jar's can be shared. Take for example log4j. You will find it in many web-apps, but if you try to put it into your common class loader, it will only be initialized by the first web-app. The other web-apps will be able to use it, though. But you will get strange results. Any globally shared ressource, such as static variables or Singletons will get you in trouble. So: Don't do it.

Allright then, I'll buy that, if somewhat reluctantly. The creation or retrieval of a session, as far as I understand it, is totally under application control. In other words, if your servlet (or JSP), when it is called, executes a HttpServletRequest.getSession() call, then it will retrieve the existing session (or create one if none exists yet); and if it does not call getSession(), it will not.

Re: Session timeouts: ignore periodic polling URL?
If ajax requests need session state, then IMO Tomcat can not help you with that - it can not and should not differentiate requests issued by ajax and requests issued by user. In that case one solution would be to logout user with a logout request after timeout. Where ajax requests live, javascript is enabled, so on page load you can just https://developer.mozilla.org/en/DOM/window.setTimeout to logout request, where client side timeout duration could/should be same as server side session timeout.

RE: Installing Tomcat the Brute Force Way?
Not necessarily. I did an rpm -qlp on tomcat-6.0.18-0.noarch.rpm. All the files it installs are in /opt/tomcat The files, yes. But it is highly likely that it installs also links from /etc/tomcat, /usr/share/tomcat, /usr/lib/tomcat, /var/lib/tomcat and so on. At least, that is what most Linux packages that I know are doing. So if I look in all the places you mentioned and I don't find any tomcat files or links, is it safer to say that the package did not actually install files outside the /opt/tomcat tree? Better yet, is there an easy way to look into an RPM package and see what all it does in terms of cearting links and such? --Eric Disclaimer - March 20, 2011 This email and any files transmitted with it are confidential and intended solely for Tomcat Users List.

Tomcat 6 graceful shutdown
Hi, I'm running Tomcat 6.0.26 on Solaris 10 and have a question about what exactly happens during Tomcat graceful shutdown? I guess first thing it does is stop accepting new sessions on the listening ports. Sessions only or it stops accepting new requests from the already established sessions? Does it wait for the current sessions to end (I don't think so since this might take very long time) or just for the servelets to finish their current requests? What happens exactly with the servlets and the threads? In general, how the threads and servlets are being destroyed during graceful shutdown? When I issue the following command from the unix shell: # $TOMCAT_HOME/bin/catalina.sh stop 600 I can still see the server being shut down in less than 10 seconds although I specify 10 minutes delay. Does that mean that the server has already shut down all the resources properly and doesn't have to wait for 10 minutes? Is the unloadDelay specified in the application Context the only wait of controlling the shutdown process (the servlet unload time)? How can I make sure that all the requests finish before the server shutdown? Thank you very much for your help.
