session replication in tomcat5, invalidate()
I can't destroy my sessions when I have multiple tomcat instances in a cluster. This is what I do HttpSession session = request.getSession(); // something session.invalidate(); When I have one tomcat server running (clustering is enabled) the session is invalidated, but if I start two instances and run the test again the session is not destroyed, it exists in both tomcat instances. I am confused ;-( Any help is greatly appreciated. Mats - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: IIS 5.1 and Tomcat 4
True, my mistake. ;-) The module that could not be found, it seems like IIS is talking about isapi_redirect.dll. I don't know really how it all works with these isapi filters, but the file should be downloadable from a browser, so you should try pointing your browser to http://locahost/jakarta/isapi_redirect.dll and make sure you can download the file. If that does not work you have access problems. The IIS user can't reach the file. I think we are close to a solution now. Mats Jon Skeet wrote: [Replying to two posts from Mats at once] (About not being able to sniff local packets) Correct, but can't you use a browser on another machine? Yes, but that wouldn't help - it's the IIS-Tomcat communication which is at issue here (I thought, anyway) and that would still be local. I don't have easy access to another machine to test all this with IIS on one box and Tomcat on another - although it's the next step if I can't get anywhere soon. What do you get in the browser when trying to connect? The specified module could not be found. Jon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: IIS 5.1 and Tomcat 4
That explains the localhost part. Then I would try with a network sniffer (or whatever they are called) to find out if IIS tries to contact tomcat at 8009. If you don't have one, I suggest Ethereal at www.ethereal.com/ BTW: Do you get a strange stacktrace at startup (MBean something...)? Do the tomcat shutdown take a long time? If so, you can try removing the connector at 8009 and instead use the 8081 one at port 8009. The org.apache.coyote.tomcat4.CoyoteConnector is a new one used with jk2, but I can't imagine that it won't work with jk as well, since the protocol is the same (ajp13). Also you can add these rules to uriworkermap.properties, just to see if anything changes in the log file: /localhost/mobilizer/mobilizer/*=$(default.worker) /mobilizer/mobilizer/*=$(default.worker) Mats Jon Skeet wrote: snip log It seems like /mobilizer/mobilizer/ finds its way through, but the path /localhost/mobilizer/mobilizer doesn't. Is that correct? What is the path starting with /localhost, is this really your intention? There shouldn't be any path starting with /localhost. I'm visiting the URL http://localhost/mobilizer/mobilizer but the localhost part is the servername, not the path.

Re: Load balancing with 2xTC5, 1xIIS and jk2
Thank you for your answer. The configuration file below works for jk, but I want to use jk2 because it does not cause exceptions to be thrown at startup and it does not hang tomcat during shutdown in later tomcat releases (has something to do with Managed beans). I have found some information about jk2 configuration that may solve my problem. I will post a sample workers2.properties here if it works. I think there is a default load balancer named lb:0 that is used if no load balancer is defined.

Re: Tomcat 5 clustering
Can anyone recommend a good solution for an external loadbalancer. I need it to have failover (two physical servers or something) and they must listen on the same IP of course. Another preference is a low price. My actual question is, how do you do these things with Tomcat? Thanks in advance! Mats Ralph Einfeldt wrote: There are two options: - Use sticky session. In this scenario you don't need session sharing to do load balancing, but it would make the system more fail safe. (If one tomcat gets out of service, sticky sessions without session sharing loose all data from the current sessions on this server) - Use no sticky sessions. In this case session sharing is a must. You can have loadbalancing without apache and still use one domainname. Just use an external loadbalancer. -Original Message- From: Jan Agermose [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 09, 2003 3:50 PM To: Tomcat Users List Subject: Re: Tomcat 5 clustering If you have apache in front of the different tomcat instances, apache would route the same browsersession to the same tomcatinstance on each request, or not?

Re: Tomcat 5 clustering
Thank you for your answers Filip! I have now successfully tried the cluster configuration in Tomcat5 with a simple webapp. About the balance product, I cannot use it because I'm on windows, but thanks anyway. Maybe my next project will be running on Linux.

Tomcat 4 and 5 cluster
Why is there so little noise on the web about clustering/session replication on Tomcat? I think Tomcat is a superior servlet engine (yes that's my opinion), but I need session replication on my latest project. I have tried Filip Haniks package, which works great, but I have not found any recent work on this for Tomcat 5. I also found some documentation about DistributedManager which may be the answer to my needs, but how do I use it? If you have some best practices to share or any information about recent work on a stable solution that will work in Tomcat 5, please let me know. Best regards!
