Re: Strange redirects with Apache 2.0, mod_jk and Tomcat 5.5
often, Firefox tellst me, that the redirect limit is execeeded when surfing one of my pages. So i tried wget, and look at the result: [strange result] That's no joke! (www.mysite.com is a replacement for the real-website). Look at the redirects! he's even jumping to /html/index.jsp - and for some reason, tomcat redirects back to / - and than back again to /html/index.jsp. That absolutly makes no sense! /index.jsp contains a simple redirect - and /html/index.jsp is a simple page. Well, i recompiled apache, but didn't recompile mod_jk - well, the result was the one i described. After recompiling mod_jk, everything is fine again! signature.asc Description: OpenPGP digital signature

Re: strange exception - need advise
Hello! If you want to locate line which causes this error, you can insert loggers on your page. This way you could determine, which line is the reason of error, and what should be fixed. The other possible solution is to set response.setBufferSize(... large number ...); for example, response.setBufferSize(10); in the beggining of the page. Then error page will work properly with this modification, so you will be able to see exception in log.

Hi,
i declared an anttask which precompiles my JSPs. All works fine with TC

After upgrading to TC 5.5.7 i got this error:
BUILD FAILED: C:\eclipse3\eclipse\workspace\ecs2\build.xml:134:
org.apache.jasper.JasperException: The absolute uri:
http://java.sun.com/jsp/jstl/fmt cannot be resolved in either web.xml
or the jar files deployed with this application
Only one JSP would be precompiled. This was the first page (error.jsp)
in my JSP-hierarchy and makes no use of JSTL.
After simply changing my TOMCAT_HOME environment variable back to TC
5.0.29's home it works again for all JSPs.
Now i tried to localize the root of this behavior by simply adding
this taglib directive to my error.jsp:
%@ taglib prefix=fmt uri=http://java.sun.com/jsp/jstl/fmt; %
I would excpect that now error.jsp could not be precompiled too. But
oh wonder after this all JSPs could be precompiled correct.
I think this behavior is not correct or did i something wrong?

I check it personally for the entire day. since our developers work on the server the entire day, I am sure there is that it works. but when we shut our office and come next day morning, the application does not respond. what could be the problem. it is strange to see that when the server is under some kind of a small work load it works absolutely fine. but when we don't touch it for the entire night the thing sympally does not work. does tomcat also require warm-up? haha. by the way, I have kept the jdbc (jar) library in the common/lib directory as all my applications are database based. is it the right thing to do? and lastly what steps should I take to avoid the above mentioned problem. one thing I will like to mention. when the application give problem in the morning, it responds with just the title and when it comes to the database connection it gets stuck I believe. but when I run some console app with the same jdbc driver it properly connects to the same database/table. and the application works fine when I reload again.

I have used Apache Jmeter (http://jakarta.apache.org/jmeter/). This is a great tool, but sometimes a bit slow at sending the concurrent requests. I think they have a networking option to send many concurrent requests from different hosts. Hope this helps...

Re: Strange problem

I can see the directory structure and regular html pages works fine, any ideas? I have a couple of thoughts. 1. Make sure that Tomcat is using Sun's jdk and not GJC. You can do that by setting JAVA_HOME in /etc/profile, and making sure that whereever you installed the jdk is before /usr/bin in the path. Or, you can move all of the GJC stuff out of the path. 2. If I recall correctly, you'll need a copy of tools.jar in $CATALINA_HOME/common/lib 3. Depending on which kernel you have, (later FC 2 kernels and all FC 3 2.6 kernels), there is a problem with the new threading model and j2sdk 1.4.1. The best bet is to upgrade your j2sdk to j2skd1.4.2_06. I currently run Tomcat 5.028 on Fedora Core 3 with j2sdk 1.4.2_06 and have no problems. I have jdk1.5, but I've not upgraded my Tomcat to 5.54 and recompiled my applications yet. Hope this helps /mde/ . . . . just my two cents __ Do you Yahoo!? Yahoo! Mail - now with 250MB free storage.

Re: Strange problem with Apache2/Tomcat4 part II
I think that this has been discussed on the list before. You might want to check the archives. If I remember correctly, this happens on a Redhat 9 system where the SSL libraries have been installed via RPMs. Before running your configure commmand, setting an environment variable via the following: export LDFLAGS=-L/usr/kerberos/lib You may also run into gdm issues as well, but given your location of Apache, I'm guessing that you compiled httpd on your own. If this doesn't solve your problem, check out the marcs.theaimsgroup.com archives and look for md5.

JDK1.4+ ships with Xalan. As such, it is an endorsed library. You shouldn't be putting endorsed libraries in WEB-INF/lib. Since Tomcat adds Xerces and xml-apis to common/endorsed, they become endorsed libraries as well. Tomcat classloaders will actively ignore endorsed libraries sitting in WEB-INF/lib. As such, your own versions of the libraries are doing nothing whatsoever being there. If you want to update Tomcat with the latest Xerces and xml-apis, delete the existing ones from common/endorsed and add yours there. You can also add Xalan there, but probably should add it to JAVA_HOME/jre/lib/endorsed (create the directory if it doesn't already exist). I suggest you use the 2jars release to avoid making BCel (which Xalan ships with... and old version at that) an endorsed library.

But I have not found how to do this. My fear is that on different application servers the behaviour is different. If this is the behaviour that you want, then you only have to worry about the case when the user goes from http to https (because you want a new session instead of the old one). One way to do this would be to record the type of connection (secure or not) in the session when it is created, and then when you go to a secure connection, check the value you stored (in the session). If it indicates that the session was not originally created by a secure requested, invalidate that session, and create a new one. I think that will probably work.

Hi, So BEA is telling you that if you say page buffer=64kb and they give you 12kb, that's the spec? ;) Yoav Shapira Millennium Research Informatics -Original Message- From: Jason Irwin [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 19, 2004 5:23 AM To: '[EMAIL PROTECTED]' Subject: Strange behaviour with buffers Apologies if this is in the wrong group, I think that User is the right one. I have noted a difference between how Tomcat (4.0.6 and 4.1.127) and WebLogic (7.0 and 8.1) assign buffers, and I'm trying to figure out which one is correct. I have an outer page that does not define any buffer, and an inner page that does, e.g.: outer.jsp html body Outer buffer is %=out.getBufferSize()%BR Outer remaining is %=out.getRemaining()%BR jsp:include page=inner.jsp /BR Outer buffer is now %=out.getBufferSize()%BR Outer remaining is now %=out.getRemaining()% /body html inner.jsp %@ page buffer=64kb % Inner buffer is %=out.getBufferSize()%BR Inner remaining is %=out.getRemaining()% Tomcat reports 8kb for outer.jsp and then 64kb for inner.jsp. The remaining buffer sizes are unrelated. WebLogic reports 12kb for both and the remaining buffer are related. It's as if Tomcat creates new JspWriter for each dynamic include, but WebLogic keeps using the same JspWriter. BEA have confirmed that this is their expected behaviour. Is anyone able to confirm if BEA are correct in their interpretation of the JSP Specification and, if so, why Tomcat is behaving the way it does? Is this just a case of a differing opinion on the same spec? I've had a look through the documentation and drawn a blank.

Re: Strange Session id behavior
Gretar Simonarson wrote: I'm maintaining a JSP/servlet web using SSL, running on Apache 2.0.48 and Tomcat 5.0.18. Cookies are used for session identifier communication (not url rewriting). Some users using the web are experiencing very strange session id behaviour, the behaviour is like this: When these users make their first request to the web, they already have an session id that is invalid, i.e. request.getRequestedSessionId() is not null and the id is not a session id that has been recently created by Tomcat (I've a session listener in Tomcat that logs session creation and destruction). As expected, Tomcat creates a new session id for the users (because the session id is invalid) but the next requests from the users do not use that session id but instead continue to use the session id that they used in the first request. So Tomcat continues to create new session ids for each request, example: request.getRequestedSessionId() - request.getSession(false).getId() request.getRequestURI() 01A960C22480CE9F445CDE48DE333F31 - 451BA13F85AE631148022C93DFDD2811 - /first_request.jsp 01A960C22480CE9F445CDE48DE333F31 - CBF44C3C065502D6397BC44A7AB659F9 - /second_request.jsp 01A960C22480CE9F445CDE48DE333F31 - 6453C03AF5DD2B9EA1F27D225589E8B2 - /third_request.jsp 01A960C22480CE9F445CDE48DE333F31 - 93F173966F28A972A2E70C32CC8E848B - /fourth_request.jsp If the users close their browser and try again - they (most often) continue to have the same problem but request.getRequestedSessionId() is not the same as it was at last time...

My production server setup is Apache/1.3.19 (built on HP-UX)mod_ssl/mod_jk/tomcat 4.1.29 on a separate machine I have a moderate loads of 5-10 hits per second and no really big responses (no more than 300k) What I know so far is that this is caused by an attempt by the coyote connector to write in a already closed by the mod_jk socked. The hints I have so far: 1. some proxy servers in the middle might explicitly close lenghty collections 2. lotso ppl blame users pressing stop button in browser!? 3. I follwed some forum thread somewhere (cant remember now) where the guys had observed as a weird bahaviour of Windows IE. They had narrowed the log entry appearances to a hit to a page where the request was submited like this: a href=blah/blah.html onclick=if (boolean_exp) some_form.submit() They were saying that the IE evaluates the onclick and submits the form, at the same time requests the blah/blah.html document, and THEN decides that the blah/blah.html document is not needed and just closes the socket. The guys also were saying that such a behaviour was not observed while tested with Mozzila and Opera browsers. They have been able to avoid it just by making the onclick event handler return false: a href=blah/blah.html onclick=if (boolean_exp) some_form.submit(); return false Though, I have not tested it myself. -Original Message- From: Chris Joelly [mailto:[EMAIL PROTECTED] Sent: 15 2003 . 10:31 To: Tomcat Users List Subject: Re: strange error messages in tomcat log and mod_jk2 log Hi! thanx for your reply. hm. it's a very strange thing. some questions: are you running your application under heavy load? are the responses very big in size? do you use the apache2/mod_jk2/tomcat4 config on a windows nt4 box? does a dialogbox appear on the server with an error message stateing that the apache.exe caused an internal error, and after pressing Ok the apache2 server continues to run? maybe we can find some similarities. we have no idea what direction to look for, and the problem is very critical because a very big application is crashing every few minutes, so a production environment couldn't be setup... :-(( thx, Chris Am Fri, Dec 12, 2003 at 01:46:13PM +0200, Altankov Peter meinte: Hi!

RE: Strange number of processes....
First of all keep in mind that it aren't processes, they are threads. As the threads share the same memory they do not use much additionals memory (some memory for the thread local objects and the thread stack and so on) I can't explain all your numbers. - Even the simplest java program has more than one thread. Depending on the vendor and the vm version you may have several threads. (Mine has 'Finalizer', 'Reference Handler', 'Suspend Checker Thread', 'VM Periodic Task Thread', 'VM Thread', 'Signal Dispatcher' and 'main') - Tomcat uses some threads as monitors. The number of monitors depends on the tomcat version and the services you enable/disable - There might be no relation between minProcessors and the number of threads, as it's tomcat's choice if and when additional threads are created (which may be stored in a thread pool for later reuse). - If you set minProcessors = maxProcessors this might give a better relation to the number of threads but there is no contract that enforces tomcat (or any other servlet container) to limit it self to a certain amount of threads. - If you want to know what the threads are doing, you can issue a 'kill -QUIT jvm-pid' and look at the stacktrace in catalina.out. (the thread names give a good hint about purpose) -Original Message- From: Scott Queen [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 10, 2003 2:12 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Strange number of processes Ok I'm running Tomcat 4.1.18 as a standalone server on a Linux box. I've configured 6 virtual hosts in the Tomcat-Standalone server having a non-SSL Coyote HTTP/1.1 Connector (probably obvious) and a Coyote/JK2 AJP 1.3 Connector (I don't think this is used, but I'm not sureunfortunately reveals my lack of experise!). I'm confused with the number of java processes spawned when I start Tomcat. Here is what I see: # of initial minProcessors | maxProcessors | java processes | comments 1 | 1 | 25 | can't get a page 1 | 2 | 27 | pages served to 1 session 2 | 4 | 31 4 | 4 | 31 | slow response, 1 session at a time 4 | 7 | 31 | 3 sessions respond, 4 add'l java procs created 5 | 7 | 31 | same as above 4 | 20 | 31 | 5 sessions respond (all tested), 9 add'l java procs So. First question: why are there so many java processes when I specify only a few minProcessors (i.e. 1 minProc, 1 maxProc, 6 virtual hosts - I would expect 6 java sessions)? Second question: why isn't the number of initial java processes a linear relationship relative to the number of minProcessors specified? I'm concerned about this because in the end, only about half the processes are ever used, but they all take up a significant amount of memory. How do I reduce the memory utilization?

RE: Strange GET error with recent linux upgrade.
I didn't get a response on this, but I did solve the problem and thought I would pass it on just in case someone else runs into something similar. I found out that the web.xml file was an older version that used an older DTD (2.2). It was tied to an older version of tomcat. I think around tomcat 2.something. When they upgraded to the latest red hat enterprise linux, they were using tomcat 4.1.29. The 2.3 DTD that is used by 4.1.29 includes the servlet-mapping/servlet-mapping tags that let you specify the url-pattern for your servlets. As soon as I upgraded the web.xml file to the new version, and included the servlet-mapping, everything worked perfectly. I still don't understand why I got the original error message: HTTP Status 405 - HTTP method GET is not supported by this URL I would have expected a servlet not available message if tomcat couldn't find it because the web.xml file was wrong? -Brian -Original Message- From: Brian Menke [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 26, 2003 10:47 AM To: 'Tomcat Users List' Subject: Strange GET error with recent linux upgrade.

Re: Strange file explorer errors since 4.1.29 installed.
I have been developing with tomcat 3.3.1 running on both windows 2000 (professional (but not server version)) and solaris for close to a year now. I have had no problems most likely because the stuff I am doing is relatively simple types of things at the present. I installed 4.1.29 last weekend mostly because I dont like to get too far behind and I was picking up strange socket error on unix. Someone suggested I move to the newer version. When I installed and ran it sunday night and monday all of a sudden my file explorer would get an error and exit about every 10-15 minutes. I thought, virus or disk error so I scanned by disk for errors and viruses. It found nothing. I reset my environment back to the 3.3.1 and ran the rest of the day and this morning with out any file explorer errors. Later today I plan to set my environment back to 4.x and see if the errors start happening again. Has anyone else had any experience with this type of problem? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Strange behavior of runtime.exec(...)
Stefan, The security manager is disabled per default. In your specific case it has nothing to do with the security manager either. The problem is that the program/script you started with runtime.exec() doesn't have permission to open a socket. The security manager, if enabled, could control the permission to use .exec() and .exit() methods in your java code. Not in external scripts/programs you execute. As I told you, I worked around this by rewriting the program in as a servlet. I never got the original CGI program to open a socket. I think external programs launched by Tomcat always have this restriction.

Re: Strange behavior of runtime.exec(...)
Thank you Patrick, after opening up all permissions for the web-app following your advice we finally found the reason in a bug in the ypbind of the machine running tomcat: so my guess, that spawned processes are restricted in any way were obviously wrong - especially there does not seem to be a way of restricting spawned processes. Either you are granted permission to exec or not, but nothing in between (this is fine by me, we are just happy to have our exec's run smooth again...) thx for the help stf Patrick Willart wrote: Stefan, The security manager is disabled per default.

If you get a NPE inside charAt on a constant String, I think it means
your VM has issues.
For the first one, the engine associated with the engine valve is null,
which can't happen either, but I can't demonstrate as easily that it's
not a Tomcat bug.

RE: Strange tomcat behavior
Howdy,
I recall having the charAt NPE -- it went away during an upgrade of the JDK (to 1.4.2)
and tomcat (to 4.1.27). At that time I also had them update all the Solaris OS
patches required by the JDK. So I don't know which was the deciding factor in the
charAt NPE you're getting, but doing all the updates should work ;)

RE: Strange exceptions ...
Actually I figured out what is happening and why the error is there. It was something along the lines that you described except user does not stop anything but for some reason images do not get served correctly. I am not sure why. I read somewhere on either this list or the struts list that for some unknown reasons in exactly the configuration that we have (ApacheSSL-Tomcat) the images do not get served correctly (between the mod_jk and coyote I guess), and I noticed that they get cut off or do not get to the client, when I get the info message. The broken pipe happens inconsistently, so I can not make much sence of it, but I suspect it has something to do with the sme problem It is no bigy for now since the refresh or consequent requests do serve the images correctly and once it is there browser does cache it, but I would like to solve it one day, any ideas of where to start my complains or maybe it has been alread y solved and I am just wasting my breath here ...

Strange. How is your test set up, that is:
- Is the command-line class on the same server as JBoss?
yes, it's on the same server, but in another jvm, the tomcat-instance also.
- Is the test class in the same jar as the bean class?
i didn't package the jar. just plain .class-files-directory in the
classpath.
- Are you sure the Getter isn't doing another lookup?
I'm sure, the getter getId() only return an Integer. Should be fast.
- I have no clue why serialization is two orders of magnitude slower...
:(
I was first thinking it's a problem with all the jars in the classpath and
reflection, but it I run my commandline test with the same classpath and the
same jvm options like tomcat, it slows down only about 5 to 10%

Re: Strange request.setAttribute() problem
This is the correct behavior. In this scenario, you are operating on the
request, not the session.
request.getParameter -- Get stuff from the query string (or input stream if
post) - a per request thing
request.setAttribute -- Set an attribute in the life of this particular request

Hello, I come across a problem with TC4.1.24 and hope fellow list users
can help me...
I set a variable in a servlet by calling:
request.setAttribute(itemnumber,

A JSP will then detect if this variable exists or not by:
if ( request.getParameter(itemnumber) != null ) {
try {
itemnumber =
Integer.parseInt((String)request.getParameter(itemnumber));
} catch (NumberFormatException ex) {
System.out.println(No);

I have two different web browsers opened (say, one IE and one Opera),
and both eventually will come to the page containing the code above.
The strange thing is that if the variable itemnumber is set via IE,
the same itemnumber will be seen at Opera!
This shouldn't happen as both have different session ID, and are
completely unrelated.
Who has come across this problem? How can I work around this?
Thanks!

RE: Strange request.setAttribute() problem
he meant:
use:
HttpSession session = request.getSession( );
session.setAttribute( itemnumber,
Integer.valueOf(Integer.toString(itemnumber)));
and then:
session.getAttribute( itemnumber );

Subject: Re: Strange request.setAttribute() problem
This is the correct behavior. In this scenario, you are operating on the
request, not the session.
request.getParameter -- Get stuff from the query string (or input stream if
post) - a per request thing
request.setAttribute -- Set an attribute in the life of this particular
request

Hello, I come across a problem with TC4.1.24 and hope fellow list users
can help me...
I set a variable in a servlet by calling:
request.setAttribute(itemnumber,
Integer.valueOf(Integer.toString(itemnumber)));
A JSP will then detect if this variable exists or not by:
if ( request.getParameter(itemnumber) != null ) {
try {
itemnumber =
Integer.parseInt((String)request.getParameter(itemnumber));
} catch (NumberFormatException ex) {
System.out.println(No);
}
}
I have two different web browsers opened (say, one IE and one Opera),
and both eventually will come to the page containing the code above.
The strange thing is that if the variable itemnumber is set via IE,
the same itemnumber will be seen at Opera!
This shouldn't happen as both have different session ID, and are
completely unrelated.
