Re: Potential reuse of TagHandlers implementing JspIdConsumer?
Hi, I finally found the time to build a test case for this issue. I attach the WAR, but you still need to put the runtime library of AspectJ (aspectjrt.jar) on the classpath when running Tomcat. The behavior I observe is that whenever I load/reload the page, the JspIdConsumer objects get allocated, and some, but never all of them get GC'd. You should see messages on the console/log like Adding JspIdConsumer:someClassName:itsHashCode:theJspId and Removed someJspId You will see three Adding messages for every instance created (it's a mess to track this properly), and you should see one Removed message for every GC'd instance. When I run grep | wc on the output, the distance between the number of created and GC'd object grows over time and reloads of the test page. I had this running for a bit, trying to see if after a session timeout the remaining instances would be GC'd, but they didn't. I don't know what to make of this, but it feels like Tomcat is holding on to some of the instances for too long for no good reason.

Web.xml entries
Hi, I have a basic question about the tomcat server start-up. If there are classes missing that are referenced as servlet entries in the web.xml should this render the server unuseable? I did a little test today with a web app, and when tomcat started it reported class not found exceptions for the missing classes, and I could no longer get to the login page for the web app which is a jsp. When I fixed those errors the login page displayed fine. The error I got was resource not available (tomcat error page), I am using tomcat 5.5.

DeltaManager + Session beans: Do they like eachother?
Hello everybody, First of all, to avoid any misunderstandings, below problems relate to applications that I did not write, neither do I exactly know the implementation of them. Although, if required, I can ask the programmer for more information. That being said, the problem that I am seeing is that the application that I deployed on a Tomcat 5.5.27 cluster is not correctly handling session replication. (The application works perfectly on a single server). The reason for thinking this is that the application fails, but only at irregular intervals. When I press F5, then the page eventually comes true. As said before, this does not happen in a single server environment. According to the Tomcat logs, I can see that my request is being served by Tomcat1 and by Tomcat2, and vice versa. My server.xml configuration: Cluster className=org.apache.catalina.cluster.tcp.SimpleTcpCluster managerClassName=org.apache.catalina.cluster.session.DeltaManager expireSessionsOnShutdown=false useDirtyFlag=true notifyListenersOnReplication=true clusterLog=true clusterLogName=clusterlog Membership className=org.apache.catalina.cluster.mcast.McastService mcastAddr=228.0.0.6 mcastPort=45566 mcastFrequency=500 mcastDropTime=3000/ Receiver className=org.apache.catalina.cluster.tcp.ReplicationListener tcpListenAddress=172.18.0.39 tcpListenPort=4001 tcpSelectorTimeout=100 tcpThreadCount=25/ Sender className=org.apache.catalina.cluster.tcp.ReplicationTransmitter replicationMode=pooled ackTimeout=15000 keepAliveTimeout=2 waitForAck=true/ Valve className=org.apache.catalina.cluster.tcp.ReplicationValve filter=.*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.* \.html;.*\.css;.*\.txt;/ !--Deployer className=org.apache.catalina.cluster.deploy.FarmWarDeployer tempDir=/tmp/war-temp/ deployDir=/tmp/war-deploy/ watchDir=/tmp/war-listen/ watchEnabled=false/-- ClusterListener className=org.apache.catalina.cluster.session.ClusterSessionListener/ /Cluster Something interesting that I figured out is that if I change the managerClass from managerClassName=org.apache.catalina.cluster.session.DeltaManager to managerClassName=org.apache.catalina.cluster.session.SimpleTcpReplicationManager then the application works fine. (It keeps working when I set useDirtyFlag to false). One would think that the DeltaManager is just not replicating, but I can see the following messages in catalina.out: catalina.out:INFO: Manager[/Application1], requesting session state from org.apache.catalina.cluster.mcast.McastMember[tcp://172.18.0.40:4001,catalina,172.18.0.40,4001, alive=73627]. This operation will timeout if no session state has been received within 60 seconds catalina.out:INFO: Manager[/Application1], session state received in 104 ms. Currently the only information that I have about the application is that it's using JSF and session beans. The developer said he does not need to explicitly put session.SetAttribute(whatever), since this is automatically taken care of by the session bean object. I'm not a Java programmer, so I'm not sure whether that is correct. I would really appreciate if someone could point me into the right direction. Btw. I cannot change the managerclass to SimpleTcpReplicationManager, as I got other applications on the same server that start failing if that manager is used. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
mod_jk: Expected behaviour for ajp-pool currentThreadCount
Hello, I'm currently analysing issues with a quite old Tomcat 5.5.17, mod_jk 1.2.15 and Apache 2.0.55 loadbalanced setup with 4 Apaches (worker.c) and 4 Tomcats. Questions are: * Can anyone explain why Apache SYN requests to Tomcat don't get answered (probably this happens only if maxClients exceeds Tomcat AJP pool sizes). * Shouldn't the AJP thread pool shrink to maxSpareThreads, if idle, or will threads stay open if Apache ever requested them? Currently there are 4 Apaches, 2 with StartServers 2 MaxClients 300 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 and 2 more with StartServers 2 MaxClients 200 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 that have problems with hung SYN requests when getting near the 4 Tomcat's default AJP thread pool size of 200. Current guess was that it's simply a bad idea to have 2*300+2*200=1000 maxClients on Apache side and just 4*200=800 AJP threads (if evenly balanced) on Tomcat side. So firstly increased Tomcat threads to maxThreads=500 to find some peak. All other AJP connector settings are default, resp. not defined. Meanwhile we log the JMX currentThreadCount for the AJP-Pools and the thread count only increases. However even after peak hours the currentThreadCount does not decrease. However would expect to get back to the maxSpareThreads default of 50 during night time. Can anyone explain why the AJP thread count stays high? I saw that one could configure mod_jk connection_pool_timeout which is not done yet. Could that be the reason for the thread pool never reducing the thread count even though the AJP thread pool has a maxSpareThread setting (i.e. doesn't this have an effect without pool timeout?)? What could be the reason for SYN requests of the Apache that never get answered by Tomcat?

HttpServletRequest#getSession(false) says the session is good, but session is still invalid!

HttpSession session = request.getSession();
--
and yet, later on in my code, a call to session.setAttribute() throws

I've guarded against an invalid session by checking for one, yet there
it is on the first attempt to use it!
Help! Thanks!

Presumably, your code has called session.invalidate() during the
processing of the current request. I'm not sure what happens if you do this:
session = request.getSession();
session.invalidate();
session = request.getSession();
session.setAttribute(foo, bar);
Will this fail on the setAttribute, or will the second getSession give
you a new session?
My guess is that your code does the above, but without the second
request.getSession(), so you end up with an invalidated session into
which you are trying to shove attributes.
Maybe you could post the code?

Re: HttpServletRequest#getSession(false) says the session is good, but session is still invalid!
Hi Chris,
Thanks for your response. I actually don't invalidate the current
session there. That's what is so frustrating -- the code snippet I
provided is at the very top of the method, and there's no more reference
to the session or request until using setAttribute.
I don't mind providing the code -- it's at http://java.pastebin.ca/1283742.
Actually, looking at it in the pastebin -- could it be that I'm setting
an attribute FOR the error about a missing session?
Hmm did I just solve my own problem?

Yup! Look at your error handling code:
if(!request.isRequestedSessionIdValid() ||
request.getSession(false) == null)
{
request.setAttribute(WebUIConstants.ERROR_MESSAGE_DETAIL, Your session has
timed out. Please login again.);
return

That just ain't gonna work. I think you want to set an attribute in the
request, not the session.

The link to the wiki sends you to http://wiki.apache.org/tomcat/TomcatVersions which I believe answers your questions.

Re: service.bat install failure (Windows, v 6.0.18)
OK, I have a *procedural* resolution to my issue, however I do not yet understand the underlying functional mechanism to my satisfaction. For those who only care about the bottom line, here it is: * If you want to use Tomcat as a Windows service, use the .zip Tomcat * distribution, not the .tar.gz distribution. I think it is worth elaborating some though. If anyone out there has influence on the build and/or documentation, I hope you will read further. 1. Rainer Jung suggested that the behavior difference I see between the two distros could be expained by line-ending differences/incompatibilities (particularly in config files). This does NOT appear to be true in my case. I've looked at the .xml files in the /conf directory, and they have *nix style line endings in BOTH distros. 1.1. The fact that the .tar.gz version is so close to correct on Windows, makes me hope to eventually track down the precise cause of failure; it might be interesting. Remember, I have seen Tomcat work flawlessly for more than a month when run as an app, and the Windows service installs without visible error. It is only that the server won't return pages when run as a service. 2. If the .tar.gz archive is targeted for *nix only, it sure would be nice if this was stated explicitly on the download page: http://tomcat.apache.org/download-60.cgi 2.1. I followed the README link -- it only goes to a page that says Hosted by Linux resources 2.2. In the file RUNNING.txt, there is also no explicit mention of differences. In fact, I get the strong impression that both are equivalent since the instructions just say to use different startup scripts for the different platforms. At very least, can I suggest adding my experience as Troubleshooting issue (4) at the bottom of this file? 3. From what I am seeing, it appears that the .zip and .tar.gz archives were actually created from different source trees, as oposed to just being different compressions of the same source. The differences are minor, but not attributable to tar version incompatibilities, for example. If that is true, then I suggest NOT adding files with extension .exe to the .tar.gz build/distribution. Doing so seems like an implicit confirmation that the distro is meant to be run on Windows. For those of you who think that I deserved this for being silly enough to extract the .tar.gz distro on Windows in the first place, well, maybe. I'll definitely use .zip in the future whenever there is an option. But keep in mind that I've used tar quite a bit on Windows -- I haven't seen anything like this before. When I first downloaded Tomcat, I remember thinking it was really cool that it could be offered as a platform independent Binary Distribution thanks to Java. And man, the failure mode is subtle -- I didn't see it until after a month of use. Chuck, sorry to report such a silly resolution. But I'm still kind of glad for the experience. Although a lot of your advice turned out not to be related to my problem, I'm a better Tomcat user as a result.

Tomcat 6 Cluster Setup- Server1 simply hangs sometimes - won't start...
We installed.tomcat6 in production on three high ended machines
Tomcat Version JVM Version JVM Vendor OS Name OS Version OS Architecture
Apache Tomcat/6.0.18 1.6.0_07-b06 Sun Microsystems Inc. Windows 2003 5.2
amd64
1) Cluster is setup correctly in the server.xml as follows
2) web.xml has distributable/ flag
Problem1 : While starting tomcat6, sometimes it starts other times it
simply hangs on the following message:
INFO: Manager [localhost#/ivos]; session state send at 12/12/08 12:34 AM
received in 110 ms.
Tomcat Log:

received in 110 ms.
After this nothing happens simply hangs. Should I use
tcpHostListener=MYIPAddress or auto May be auto is slowing it down?
Problem2: User does not transparently fail-over to node2 if the users fails
on node1.
However, the session count on all the nodes in cluster has correct number.
Means replication does work.
I have attached server.xml

RE: Tomcat 5.5 manager deploy context descriptor
From: Christopher Schultz [mailto:ch...@christopherschultz.net] Subject: Re: Tomcat 5.5 manager deploy context descriptor Is there a way to see, if my context.xml is actually loaded anywhere? You might want to try loading LambdaProbe (http://www.lambdaprobe.org/). You can also use JConsole, if you start Tomcat with the -Dcom.sun.management.jmxremote option. Under the MBeans tab, follow this branch: Catalina - WebModule - //[host]/[contextPath] - none - none - Attributes. There you will find a good bit of information about the webapp, including various Context parameters and servlet information from web.xml (double-click on the bolded array items in the rightmost column to open them up). There's also a Catalina - Resource branch that has information about any Resource elements in use. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: mod_jk: Expected behaviour for ajp-pool currentThreadCount
Michael Echerer m...@tngtech.com wrote in message news:49426119.3060...@tngtech.com... Hello, I'm currently analysing issues with a quite old Tomcat 5.5.17, mod_jk 1.2.15 and Apache 2.0.55 loadbalanced setup with 4 Apaches (worker.c) and 4 Tomcats. Questions are: * Can anyone explain why Apache SYN requests to Tomcat don't get answered (probably this happens only if maxClients exceeds Tomcat AJP pool sizes). That is the most likely reason, but there are other possibilities that should show up in your Tomcat logs. * Shouldn't the AJP thread pool shrink to maxSpareThreads, if idle, or will threads stay open if Apache ever requested them? With the default settings, the threads will stay open if Apache ever requested them. With a version this old, you probably want to specify a connectionTimeout=xx in the Connector protocol=AJP/1.3 ... / element to allow threads to die if they aren't reused in a timely manor. In this case, you probably also want to configure mod_jk to use CPING/CPONG so that it can detect that the thread went away. Of course upgrading Tomcat makes available the APR and (experimental) NIO AJP/1.3 connectors, which allow a huge number of connections without tying up threads. Currently there are 4 Apaches, 2 with StartServers 2 MaxClients 300 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 and 2 more with StartServers 2 MaxClients 200 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 that have problems with hung SYN requests when getting near the 4 Tomcat's default AJP thread pool size of 200. Current guess was that it's simply a bad idea to have 2*300+2*200=1000 maxClients on Apache side and just 4*200=800 AJP threads (if evenly balanced) on Tomcat side. With the default settings, yes this is a bad idea ;). You need to have at least as many AJP threads as maxClients+1 in the default case. So firstly increased Tomcat threads to maxThreads=500 to find some peak. All other AJP connector settings are default, resp. not defined. Meanwhile we log the JMX currentThreadCount for the AJP-Pools and the thread count only increases. However even after peak hours the currentThreadCount does not decrease. However would expect to get back to the maxSpareThreads default of 50 during night time. See above. The thread count will never go down without specifying a connectionTimeout. Can anyone explain why the AJP thread count stays high? I saw that one could configure mod_jk connection_pool_timeout which is not done yet. Could that be the reason for the thread pool never reducing the thread count even though the AJP thread pool has a maxSpareThread setting (i.e. doesn't this have an effect without pool timeout?)? I've never tried to do this on the mod_jk side, but the archives suggest it doesn't work well. What could be the reason for SYN requests of the Apache that never get answered by Tomcat? That the thread-pool is exhausted is the most common reason. But since the default AJP Connector answers the request on the current thread and spawns another thread to go back and listen for connections there are other reasons (e.g. an OOME when spawning the thread) why it might fail. However it should say in the Tomcat logs what the problem is.

Re: Restricting IP address and redirecting
Flemion Shafeeq flem...@hulmail.harvard.edu wrote in message news:5.2.1.1.2.2008123217.02090...@hulmail.harvard.edu... Hi, We restrict IP addresses to our application using RemoteAddressValve. But we have a requirement of redirecting the request to a customized html static page when we get request from such denied IP's. How do i do this. Is it possible to customize this class to do this redirection and deploy it in the tomcat application? Tomcat is open-source, so it is always possible to customize it any way you like ;). If your webapp never sends a 403 (Forbidden) response (e.g. you don't authenticate users), then you could do it by specifying a custom error-page for the error code 403. If you send a 403 response for other reasons, then it is likely that it will be easier to roll-your-own Filter based on the code from RemoteAddressValve. Please help. we are using tomcat 5.5 Thanks Flemion. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
