Of course, you can always subclass/extend a connector just like any other tomcat element to add the behavior you want. how does tomcat behave with the ajp connector? does it indefinitely spawn threads to handle requests until it bombs out of memory? or is there behaviour as specified by the acceptcount/max processors for the http connector buried in the code of the ajp connector that can't be modified? I don't use the AJP connector, so I can't answer that one, but the code is open for you to inspect at your leisure...

jk2 is ignoring graceful flag
Hello, according to http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/jk2/configwebcom.html setting graceful to 1 in the channel.socket session should disable the channel for new sessions. In my installation, the flag seems to be ignored. Therefore, I have two questions: 1. If I want a channel to get requests for existing sessions only, is the correct setting: a) graceful = 1 disabled = 0 or b) graceful = 1 disabled = 1 2. If a channel is configured for not accepting any new sessions, how can the number of remaining sessions be checked? I need this to determine if the tomcat instance can be safely switched off without kicking out users.

Re: maxProcessors vs maxThreads
I'd go with 'or'. In the TC 3.x line, the HTTP Connector really s*cked (except that with the TC 3.3.2-dev nightly, you have the option of using the same CoyoteConnector as TC 4.1.x-5.0.x :). Unless you *need* the features of e.g. mod_rewrite, mod_php, I'd agree with Yoav, and you should use Tomcat as stand-alone. Shapira, Yoav [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Howdy, Hm, we have setup IIS in front of Tomcat so it can serve off the static content, I thought that was the conventional wisdom. Conventional and/or outdated. Or is the more likely operator in the previous sentence. We're looking at about 300+ users of which maybe lets say 20 concurrent at quiet times, probably approaching 100+ when we announce something. Would you say Tomcat can handle that fairly well including the static stuff? Yeah, I would, but the specifics depend on your application, your hardware, your OS. It's not hard to test: put together a JMeter (or AB, or Grinder, or whatever tool you like) test plan that simulates however many concurrent users you expect, run it on tomcat standalone, on tomcat with IIS, on a cluster, iteratively tune the system, and see what happens. Would I just need to look at server.xml to get more performance from Tomcat (exluding the JProfiler run) or is a cluster a really good idea too. If a Again, depends on your requirements.

Re: Cannot configure to use port other than 8009
There was a bug (that I think was fixed, but I can't be bothered to look,
since I don't use Jk2 :). Jk2 was using a signed short for the port number,
which means that it can't see half of the port numbers (since it considers
'port 0 ' to be invalid). The short-term fix is to use a port 32K.

I've been having trouble configuring JK2 (version 2.0.2) to connect to a
Jetty server on any port other than 8009. I'm including the
workers2.properties file and the jk2.log. I've had similar results on
both IIS and Apache 1.3. Has anyone had any luck running on other ports?
The log below shows that it first tries to connect using port 8009 and
gets a Connection refused even though the configuration file specifies
another port (50101). It then shows it trying to connect to the correct
port and still getting a Connection refused, but I'm pretty sure that is
bogus because I can telnet to that port and get a response. When I start
Jetty on port 8009 instead (even with the below configuration) everything
works fine.
Any ideas? Am I missing some configuration parameters?
Thanks,

disableUploadTimeout
Hi everybody, I have a question regarding the org.apache.coyote.tomcat4.CoyoteConnector (Tomcat 4.1.27) What does the property disableUploadTimeout really mean? I do not understand the explanation: This flag allows the servlet container to use a different, longer connection timeout while a servlet is being executed, which in the end allows either the servlet a longer amount of time to complete its execution, or a longer timeout during data upload. If not specified, this attribute is set to false. Which connection timeout will be used if the property is set to true? Is it recommended to set it to true? Thanx for any help.

Re: disableUploadTimeout
Actually, I believe that there is a documentation error: I believe that the default value is 'true'. With all other values at there default setting, disableUploadTimeout=true means that Tomcat will use a longer timeout value (default: 5Min, like Apache/httpd) when reading the request message body than it does when waiting for the next keep-alive request (default: 15Sec). This can be usefull if your webapp uploads large amounts of data, but probably won't matter if you only POST small, simple forms.

When I set the connectionTimeout to a very high value (for example 5 hours) and the maxProcessors to a very low value (for example 3) I can see the following behaviour. I can only make 2 requests, than tomcat complains org.apache.tomcat.util.threads.ThreadPool: All threads are busy, waiting. Please increase maxThreads or check the servlet status3 3 No more requests can be performed until a restart. Does this mean a connection (socket) is as long occupied as long the connectionTimeout is set (even if the response was already sent back to the browser)? I had expected that even if the set connectiontimeout is high, the socket should be given free when the response is sent back to the client. I observed the Tomcat process by means of lsof and saw that the tomcat process has opened 3 sockets to apache. When I set a connectionTimeout to a low value (for example 15 sec) the error above (all threads are busy) does not appear any more. The lsof command shows that sockets are regulary removed and build again. I debug the Tomcat code and saw that the socket is closed when the timeout occurs. I had expected another behaviour.

Hi There, the -Xmx is what is used to limit the maximum amount of memeory that java uses. I have heard of problems in the JVM itself when using the -server, try removing this and see if this memory problem resolves itself.

RE: connectionTimeout
thanx for your answer (again ) As far as I know I cannot disable the connectionTimeout. The connectionTimeout I mean here is a property of the CoyoteConnector (and if not set the default value is 60 sec). What I do not understand is, why the socket is not free again after the response is sent back to the client. Tomcat can only accept new requests if the socket is removed (and it is removed when the connectionTimeout is reached). Cheers Karin -Original Message- From: Bill Barker [mailto:[EMAIL PROTECTED] Sent: Mittwoch, 21. Januar 2004 10:34 To: [EMAIL PROTECTED] Subject: Re: connectionTimeout Krause Karin [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi everybody, I have a question regarding the configuration/behaviour of the org.apache.coyote.tomcat4.CoyoteConnector (Tomcat 4.1.27). I use Tomcat together with Apache (over mod_jk). When I set the connectionTimeout to a very high value (for example 5 hours) and the maxProcessors to a very low value (for example 3) I can see the following behaviour. I can only make 2 requests, than tomcat complains org.apache.tomcat.util.threads.ThreadPool: All threads are busy, waiting. Please increase maxThreads or check the servlet status3 3 Yup. In the normal state, the 'maxProcessors' should be at least as big as the number of Apache children. Also, 'connectionTimeout' should usually be disabled (although on a few Linux systems, I've had problems doing this). There is a one-to-one mapping from Apache children to Tomcat socket connections. If Apache launches one more child than Tomact can handle, you will see the results as below. No more requests can be performed until a restart. Does this mean a connection (socket) is as long occupied as long the connectionTimeout is set (even if the response was already sent back to the browser)? I had expected that even if the set connectiontimeout is high, the socket should be given free when the response is sent back to the client. I observed the Tomcat process by means of lsof and saw that the tomcat process has opened 3 sockets to apache. When I set a connectionTimeout to a low value (for example 15 sec) the error above (all threads are busy) does not appear any more. The lsof command shows that sockets are regulary removed and build again. I debug the Tomcat code and saw that the socket is closed when the timeout occurs. I had expected another behaviour. I mean that not every time a new socket is established from Tomcat to apache but sockets are reused.

I think you should post the task sequence so that this is reproduceable. Yet another solution: you can create a .war in the host appBase and overwrite it to redeploy the webapp. Thanks, Remy. Here's what I do: - start Tomcat 5 - deploy WAR (localWar) - undeploy WAR - deploy WAR *BANG* If you don't post the task list, I can't help you. I've worked around this for now by having localWar point to my project, which is structured as a valid deployment (unpacked WAR) - and just using the reload action, after doing an initial install. I've noticed, however, that the temporary context.xml files don't get removed when I shut-down Tomcat 5. This seems like a bug, right? No. The .xml should only be removed on undeploy. -- x Rémy Maucherat Senior Developer Consultant JBoss Group (Europe) SàRL x - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: jspexception in admin webapp
Apu further, this is not due to clicking save or going back or any such user action, it happens as soon as i click the Service (Catalina) link. It also happened for us with any host or context nodes. (without using the back button and on all browsers) See my post here:- http://marc.theaimsgroup.com/?l=tomcat-userm=107399516922291w=2 We have since reproduced it on a similar machine, using TC 5.0.16, and assumed it was something to do with the struts libraries that came with the binary distribution. We tried replacing them with the struts/bean etc .jars from the 1.0/1.1 distributions, to no avail. However, we managed to get a working TC 5.0.16 by building from source.

This issue has been discussed many times on this list so a search of the archives should give you plenty to read. There have also been articles published on this subject so a google search should also give you plenty to read. While reading, you may run into statements that claim that Tomcat is much slower than apache at serving up static documents. While this certainly was the case with earlier releases, there have been significant improvements in both the Java runtime and in Tomcat itself that have narrowed the gap.

RE: Single session across webapps
Todd wrote: Is there a way to share sessions across webapps running in the same container? Yes, I do this for a set of apps which I wrote recently. You need to make sure each of the apps which need access to the cross-context session are defined like this in server.xml: Context path=/mycontext docBase=mydocbase debug=0 reloadable=true crossContext=true ... /Context crossContext=true is the important bit. If you're deploying your apps as WARs you'll need to deploy them, restart Tomcat, edit server.xml and then restart Tomcat again...! As for accessing this shared session, I found some code on the web ages ago which had examples but I can't find this at the moment. The code I use for reading information from the shared session looks like this: ServletContext currentContext = config.getServletContext(); ServletContext sharedSessionContext = currentContext.getContext(sharedcontextname); Hashtable sessiondata = (Hashtable)sharedSessionContext.getAttribute(attributename); However, as others have suggested, I was only able to get code like this working when loaded from common/lib or common/classes. In my case, I have this code running in a servlet filter loaded from a JAR in common/lib. Hope that helps. Robbie
RE: Apache-Tomcat integration vs Direct Tomcat
No easy answer on this one..There are proponents of the httpd-Tomcat approach who say that since Apache httpd has been developed to excel at static content delivery then you should use that. On the other hand, there are people that say that Tomcat can perform equally well at serving static content, so why burden yourself with another layer? I would say try both out, and see what performs better for YOU. Load test tomcat as standalone and httpd+tomcat together. There is no clear cut solution and nothing works the same for everyone.

This is what I have done: 1) I've downloaded Tomcat 5.0.16, and unzipped the files into a directory, (E:\tomcat_test\). 2) I have also installed the service according to the link: http://jakarta.apache.org/commons/daemon/procrun.html#Installing%20the%2 0service http://jakarta.apache.org/commons/daemon/procrun.html#Installing%20the% 20service I.e. with the following arguments E:\tomcat_test\jakarta-tomcat-5.0.16.\bin\tomcat //IS//Tomcat5 --DisplayName Tomcat 5.0.12 --Description Tomcat 5.0.12 JDK 1.4 http://jakarta.apache.org; --ImagePath E:\tomcat_test\jakarta-tomcat -5.0.16\bin\bootstrap.jar --StartupClass org.apache.catalina.startup.Bootstrap;main;start --ShutdownClass org.apache.catalina.startup.Bootstrap;main;stop --Java C:\j2sdk1.4.2\jre\bin\client\jvm.dll --StdOutputFile e:\log.txt --StdErrorFile e:\err.txt --WorkingPath e:\tomcat_test\jakarta-tomcat-5.0.16\ 3) Launched Windows Services tool, and started it from there, but then it seems to start and then it exists 4) As an alternative I started it from the command line by using the command: E:\tomcat_test\jakarta-tomcat -5.0.16.\bin\tomcatw //GT//Tomcat5 Now this works, cause the process comes up and I am able to browse the http://localhost:8080 http://localhost:8080/ page with no trouble 5) And then I started it by using the command: e:\temp\tomcat_test\jakarta-tomcat -5.0.16\bin\tomcatw //GT//Tomcat5 Now this does NOT work I've been using both regmon and filemon to try and figure out what is happening. And this is my conclusion without a solution :-( So when I am running it from the command line, from the working directory it works fine. From the tools filemon and regmon I could see important differences between when it worked and when it did NOT work. The differences seems to be that the service is very dependent on the actual working directory, cause when it did not work it failed to find the entries below, whereas when it worked fine it used the proper path to these, NOT WORKING C:\Windows\system32\conf\catalina.properties C:\Windows\system32\common\classes C:\Windows\system32\common\endorsed C:\Windows\system32\common\lib WORKING E:\tomcat_test\jakarta-tomcat-5.0.16\catalina.properties E:\tomcat_test\jakarta-tomcat-5.0.16\common\classes E:\tomcat_test\jakarta-tomcat-5.0.16\common\endorsed E:\tomcat_test\jakarta-tomcat-5.0.16\common\lib Any ideas, what is going wrong here?

Measuring latency between tomcat instances
We have an instance where tomcat instance (A) is communicating with tomcat instance (B), where instance (B) is located at another site. Instance (A) formulates a request to instance (B) and instance (B) responds with some valid response. Now, my question is, from a standpoint of instance (B), is it possible to measure latency?

Re: Measuring latency between tomcat instances
LOG4j might be nice kludge for this. On tomcat A, time the appropriate events on how long it takes to do stuff on tomcat B. Then log it in a specially formatted message. (mylogger.log(time: + timeTaken) Then do the same on tomcat B. Its easier to do on tomcatB since you can use a Valve or servlet filter and stay out of the business logic. I say LOG4J since it provides asynchronous loggers (Unless the performance on the non-asynchronous loggers are neglible in this case). But with LOG4j (or insert logging framework here) - you can use it to write to any log file or format you want. So your normal error messages can go to one file while these special messages can go to a differnet file/database/... -- Or you can compare acces log entries since it does offer a %T option for time taken. -Tim Jeremy Nix wrote: We have an instance where tomcat instance (A) is communicating with tomcat instance (B), where instance (B) is located at another site.

Hi! Jeremy Nix wrote: We have an instance where tomcat instance (A) is communicating with tomcat instance (B), where instance (B) is located at another site. Instance (A) formulates a request to instance (B) and instance (B) responds with some valid response. Now, my question is, from a standpoint of instance (B), is it possible to measure latency? If so, how? In order to measure latency between two systems (regardless of the application performing the measurement), you first need a way to synchronise the clocks at both sites. In most cases this brings a certain amount of tolerance you can't overcome. (For instance, synchronizing with an internet time server imposes a tolerance of a few miliseconds du to network packet delays). Since you will only get accurate readings from withing the application (i.e. tomcat) you will then have to make sure that both OS'es system clocks are equally accurate. (For example System.currentTimeMillis() has a range of up to 50ms on Windows9x systems). That said is it simple to write a small servlet that runs on A and makes a request to B including it's current time. A servlet on B then echos that request back to A and adds it's current time as well. Finally the servlet on A generates some kind of user output containing the measured runtimes.

Re: Measuring latency between tomcat instances
Instance B knows nothing about instance A. Instance B is only serving responses to instance A. Instance A might do a lot of work before and after it talks to instance B which might make instance B look bad even if that is the short part of a transaction. The only gotcha is if client side javascript were introduced. The javascript might be doing calls back to A introducing a nasty piece to the puzzle. -Tim Jeremy Nix wrote: Okay, let me pose another (slightly differenc) question.

TCP Windowsize

Hi everybody,
i have written a small application which connects to tomcat, sends some
data and recieves some data.
the problem i have is that tomcat suddenly sets the tcp window size to
zero so that the application stopps sending data and tomcat starts
sending its response before the request is finished. this only happens
when sending large data (ca 90+ kb)
can somebody tell me why this is happening and how to prevent tomcat
from doing that!?

Howdy, Apps should get any J2EE files they need from the container (eg: servlet.jar). You're obviously entitled to your opinion, but you're wrong on this one ;) Apps aren't necessarily going to get all their J2EE files from the container. Consider the case of a servlet/JSP webapp running on tomcat wishing to communicate to a remote JMS server. The webapp must have the JMS APIs and a JMS client implementation. These are not available by default in servlet containers like tomcat, though they are in full-fledged J2EE servers. You would then obtain the jms.jar and a client implementation for your server (OpenJMS rocks!), and put them in the WEB-INF/lib directory of your webapp. Yoav Shapira This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: Tomcat - Automatically writes a session?
Howdy, Well, the cookie is written but RAM memory must be allocated for these users as well, right? If you have a timeout set to 30 minutes, you've got a lot of little pieces of RAM being held by these users at any given time. Seems waistful to me, regardless how small they are. It just seems silly to be writing cookies for every page, regardless of whether you need one. Ignoring the fact this is a spec-mandate feature, I suggest you run a profiler on tomcat with your alleged cookie problem to see how much memory is wasted before you complain.

Session Tracking Question
I have a webapp in which a servlet will redirect to another remote webserver URL which will then redirect back to my webserver after completing its request. me.com/ServletA --- remote.com/someURL --- me.com/ServletB I need to be able to re-attach to the original session that the user had before (in servletA) after returning from the remote site to my URL me.com/ServletB. Do I need to do anything special or can I rely on the jsessionid which is recorded in the cookie for me.com to be automatically picked up when ServletB is invoked again? Or will ServletB create a new session? If cookies are switched off, what info do I need to pass to the remote server (which can POST back anything that I POST to it). Does someone have some sample code for ServletA and ServletB that allows it to identify the original session, and re-attach to it? I'm sorry if I'm asking a dumb question, but I've been checking on the net for some answers but I don't seem to be making much progress. I'm currently using Tomcat 5.0.16 Thanks for any help.

Re: Clustering question...
if I understand correctly, you have multiple tomcat instances. 1. each system has the same webapp 2. each system caches data locally 3. you want to update the application context 4. you want the cluster to replicate the application context 5. you didn't design it and have to live with it replicating the app context ideally should happen in a push manner if being in sync is of any importance. I'm not convinced enhancing the exist session replication is the best way to handle this because the data could be huge. Even if the documentation were to state, do not put large amounts of data in the application context, people will still do it and blame tomcat. the worse part is caching app context data means an additional burden on the session replication mechanism, which is dangerous. It might be better off for your app context to register for updates with a JMS server. this way, changes can be pushed to the tomcat instances. Or something equivalent to a push mechanism. peter lin Rick Szeto [EMAIL PROTECTED] wrote: As I was not involved in the design decision, I can not say whether or not that it is a good call or not.

Re: TC5 won't start on Xeon --SOLVED
You're obviously entitled to your opinion, but you're wrong on this one ;) Apps aren't necessarily going to get all their J2EE files from the container. From J2EE container, they will. Consider the case of a servlet/JSP webapp running on tomcat wishing to communicate to a remote JMS server. The webapp must have the JMS APIs and a JMS client implementation. These are not available by default in servlet containers like tomcat, though they are in full-fledged J2EE servers. Precisely. Even in Tomcat's case, you shouldn't supply j2ee.jar, you should supply jms.jar ONLY. You would then obtain the jms.jar and a client implementation for your server (OpenJMS rocks!), and put them in the WEB-INF/lib directory of your webapp. Yup! Nix. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

JProfiler with 5.0.16 vs 5.0.18 Strange behaviour
Here is something odd .. I have just installed Tomcat 5.0.18 so that it does not use IIS/JK2 like our 5.0.16 install. I have deployed our webapp on it. The profiling between the 2 is totally different. On the 5.0.16 profile just 2 requests to the webapp made the heap profile have a scale of 100-200MB being used. Now on 5.0.18 it is 10-30MB. Also, all the dynamic graphs showing heap use, object use ad GC are all really active and spiky whereas the 5.0.16 version was very linear and GC never seemed to happen. I'm no expert in this stuff but something has changed bigtime with this 5.0.18 install. They both use the same JVM too. FONT SIZE=1 FACE=VERDANA,ARIAL COLOR=BLUE --- QAS Ltd.

Howdy, On the 5.0.16 profile just 2 requests to the webapp made the heap profile have a scale of 100-200MB being used. Now on 5.0.18 it is 10-30MB. This is a very good change, to use far less memory. I'm wondering what your pages do that two requests need that much memory, but that's besides the point. Also, all the dynamic graphs showing heap use, object use ad GC are all really active and spiky whereas the 5.0.16 version was very linear and GC never seemed to happen. This is also a good change, less references being held for a long time. I'm no expert in this stuff but something has changed bigtime with this 5.0.18 install. They both use the same JVM too.

RE: Microsoft Update for XP and jsessionid error
I have IE 6.0 with the Q824145 update installed.Can you point me to a page that will exhibit trouble? I've never noticed trouble with jsessionid, but then again, I have cookies enabled. -Original Message- From: Søren Blidorf [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 21, 2004 11:37 AM To: 'Tomcat Users List' Subject: SV: Microsoft Update for XP and jsessionid error More specific: 824145 Internet Explorer 6.0 security update.
