RE: How to Suppress Server Header in the HTTP Response
From: Jatinder Kaur [mailto:[EMAIL PROTECTED] I am looking for a way to suppress the server header in the HTTP Response. I am using Tomcat version 559. Any help is appreciated. http://tomcat.apache.org/tomcat-5.5-doc/config/http.html See the server parameter - the comment unless you're paranoid, you won't need this is a bit unfortunate. While you can't suppress the server header, you can change it.

RE: Connector Compression
From: Mike Cronin [mailto:[EMAIL PROTECTED] Is there any reason why you would not want to use compression on a Connector? You're trading CPU cycles (running the compression algorithm) for bandwidth. I suspect you're also trading a certain amount of RAM (some extra buffers), though I haven't checked or measured how much so I may be talking out of my hat (as usual). Finally, you may be increasing the time to the first byte arriving back at the client, as you're increasing the amount of output the client has to generate before the first segment of the response is sent. If your servers are CPU-bound, you may not have the spare cycles; if you're tight on RAM, check whether the compression increases the memory use. If you have timing requirements, check that a system with compression enabled still meets them. All that said, a typical business application almost certainly has spare CPU, some spare RAM and no tight timing constraints on the first byte being returned - it's generally bandwidth out of the server and querying the database that are the limiting factors. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Connector http, ajp and Context availability
I'm using Tomcat 6.0 with both http and ajp connectors. They work fine and all the available contexts can be reached with those connectors. What I would like to do is to allow to access a limited number of contexts only via ajp connector. In the connector configuration I don't have anything to filter the incoming requests considering the context they are directed. Have I to use muliple Service elements ? Doing so I could put one and only connector in a service element with an associated engine, host and a list of context. Is this the right way ? BTW: I have published applications putting files with the context elements in the dir conf/Catalina/localhost. If I create a second service and a second engine named Brush where do I put the file with the context ?

Re: java.library.path / Unsatisfied Link Error problem with Linux Tomcat 5.5
I understand that if the .so library fails to load, it will also be UnsatisfiedLinkError. I do not know (haven't tested), whether the error text will be the same. If some required system libraries cannot be found, the library does not load. Those system libraries are loaded from LD_LIBRARY_PATH. If you are using JDK 1.5 or later, you may print your environment in Java with System.getenv() / System.getenv(String). See http://www.velocityreviews.com/forums/t259893-systemgetenv.html To be sure: in case you misprinted the value for java.library.path, or permissions problem, you may check if the file is actually readable. java.io.File f = new File(System.getProperty(java.library.path) + File.separatorChar + libLibName.so); f.isFile(); f.canRead(); f.canExecute(); 2007/10/17, david marshall [EMAIL PROTECTED]: Its a single .so file so does that mean the LD_LIBRARY_PATH stuff won't be relevant?

At that point I don't have Eclipse's VM parameter setting abilities available to me and the only place to put it is in JAVA_OPTS.

All threads are currently busy
Hi all, System: Tomcat 4.1.30 on Debian sarge java version 1.5.0_11 Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03) Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing) in situations with high load, tomcat sometimes stops responding and is not able to recover from that status. In the catalina.out file, i get the following line: SEVERE: All threads (75) are currently busy, waiting. Increase maxThreads (75) or check the servlet status i searched some time in various forums and mailing list archives and found the following links: http://mail-archives.apache.org/mod_mbox/tomcat-users/200408.mbox/[EMAIL PROTECTED] http://marc.info/?l=tomcat-userm=113297294417902w=2 http://www.tek-tips.com/viewthread.cfm?qid=862552page=3 http://www.mail-archive.com/[EMAIL PROTECTED]/msg127833.html Basically there seem to be 2 possible reasons for this behaviour 1. A bug (?) in Tomcat or the combination of JDK, glibc, whatever, which causes that tomcat does not recover from situations with too much requests. I could not find any information in the release notes of the Tomcat 4.1.x versions. 2. Some kind of deadlock or resource (database connections) availability problem which keeps the request handling threads from returning from the doPost/Get method. So i made a Threaddump using jstack (attached file). Most of the threads are in - java.lang.Object.wait(long) @bci=0 (Interpreted frame) - java.lang.Object.wait() @bci=2, line=474 (Interpreted frame) - org.apache.catalina.core.StandardWrapper.allocate() @bci=223, line=704 (Interpreted frame) but 19 threads are blocked in the bci 0 of the same static synchronized method called removeActiveRoles which is called from the doPost() method. - at.sonorys.dmc.utilities.ActiveRoleRemoval.removeActiveRoles(at.sonorys.dmc.utilities.DatabaseAccess, java.lang.String, java.lang.String, boolean) @bci=0 (Interpreted frame) - at.sonorys.dmc.CommDicora.CommHandleMessageSession.quitSession() @bci=23 (Interpreted frame) - at.sonorys.dmc.CommDicora.CommHandleMessageSession.doHandleSessionMsg() @bci=131 (Interpreted frame) - at.sonorys.dmc.CommDicora.CommHandleMessageSession.evalMessage() @bci=1 (Interpreted frame) - at.sonorys.dmc.CommDicora.CommDicoraServlet.doHandleMsg(javax.servlet.http.HttpServletResponse, javax.servlet.http.HttpServletRequest) @bci=103 (Interpreted frame) - at.sonorys.dmc.CommDicora.CommDicoraServlet.doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) @bci=142 (Interpreted frame) The servlet implements the SingleThreadModel (not my decision). As you can see from the threaddump, all 19 threads are waiting to get into the same static synchronized method. I dont understand this because there must be one thread IN the method which holds the lock of the method? Is it possible for a thread to leave a synchronized method without returning the lock? br, Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It rises so fast . See at what rate. Well, look at the CPU consumption at the same period - so your Tomcat is working on something. Looking at the amount of CPU time consumed, it could even be still running the application startup (Tomcat by itself can take something like 20 seconds of pure CPU time, on some machine architectures at least -- and here the CPU time usage is running from 13 to 48 seconds - so it's still too early to say whether the rise in memory usage will continue or not). What is this PermGen space. Why does not it get garbage collected. PermGen is the holding space for the program code in your currently active classes. So, looks like whatever you're using has quite a large active codebase. Is there anyway I can tell tomcat to suggest the VM a garbage collection more often than the default garbage collection algorithm does. Is there any declerative way of doing, xml, .sh? Even PermGen is cleaned in current JVM versions -- but classes can only be unloaded when there's no reference to the class within the JVM. And garbage collection overall is done when needed: it is definitely done before JVM throws an out of memory error. There's quite a lot of tunables for the JVM (including garbage collection), but pretty much you should trust the defaults (unless you have experience to actually distrust the defaults because of some specific feature in your application or runtime environment). -- ..Juha - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Thanks Arun George

Re: tomcat/java process strangeness
For you xmx: i guess bad default values that are too small regarding to heap size. This is probably due to your OS ocnfiguration at some point. Did you install java using distribution provided packages or sun packages? For you Processes, this comes from old kernel. At some point in the past, in linux, Thread where just considered special cases of Processes and tools didn't make the difference between them. So each thread had it's own pid.

The process has allocated just under 1GB of memory, but is not using it at all (since virtual - resident cannot possibly fit into your 108k of used swap, you can tell that nothing has been swapped-out). Some other process has the rest of your 2GB physical memory tied up. top even tells you that your java process is only taking up 14% of your memory. What's the problem? I have a 2GB memory.

I have an autobuild script running everyday which checkouts from sourceforge cvs , stops the servers, build it and redeploy and start tomcat.

LogConfigurationException headache
Hi all,
I am having major headaches lately with tomcat 5 and 6 regarding
logging.
It started when deploying some cocoon application to tomcat 5 and 6.
You can find an extended background summary (from me and others) here:
https://issues.apache.org/jira/browse/FOR-1049
The problem is that tomcats logging seems to seriously interfere with my
own one. I am using apache-tomcat-6.0.14 but have seen very similar
problems in 5.5.x.
I have to servlets one is based on cocoon the other one is a very simple
one.
The logging for the cocoon one is
[EMAIL PROTECTED]:~/src/apache/tomcat6/webapps$ tree boja2/WEB-INF/lib/|
grep log
|-- avalon-logkit-2.1.jar
|-- commons-logging-1.1.jar

|-- commons-logging-api-1.1.jar
|-- excalibur-logger-2.1.jar
|-- log4j-1.2.13.jar

The logging for the simple servlet is:
tree searcher/WEB-INF/lib/|grep log
|-- commons-logging-1.1.jar
|-- log4j-1.2.14.jar
Now starting tomcat with only one application it is working fine as well
when I mv the other app into tomcat there is no problem but as soon as
I *restart* tomcat. BAAANGG!!

RE: Advice about Tomcat on x86_64 architecture..
From: Swapnil.Kale [mailto:[EMAIL PROTECTED] I tried installing tomcat 32 bit on a 64 bit JVM but it didnt work. That is very unexpected. *Tomcat* is pure Java. I can do a file copy of my entire Tomcat installation and my apps from my 32-bit development box to my 64-bit staging box (and back again) and Tomcat starts and runs without error. Note that I'm using the zip download and starting it from the batch file; I do *not* install a Windows service, and I do *not* use any native libraries. 1) Can i host 32 bit compiled war file on 64 bit Tomcat / JVM ? If my tomcat installation succeeds Yes. I do this regularly. The bytecodes emitted by the compiler are identical whether the compiler runs on a virtual machine on a 32-bit, 64-bit, 36-bit or any other physical hardware. 2) What if i recompile the war on 64 bit jvm and host it on 64 bit Tomcat? Yes. I do this more rarely (my dev box is my usual compile environment), but it works. I repeat: the bytecodes emitted by the compiler are identical whether the compiler runs on a virtual machine on a 32-bit, 64-bit, 36-bit or any other physical hardware. I've read that the size of the primitive datatypes in 64 bit is different, Whoever wrote that is wrong. Java is not C. Java primitive sizes are standard, regardless of the physical machine. so if i use Java web start and launch the application from remote machine 32 bit using JNLP, will it work on that 32 bit machine? having 64 bit machine compiled jars? Yes. If I host the 32 bit compiled war on 64 bit Tomcat / 64 bit JVM, What am i gonna miss/gain? except the lot of heap memory Nothing. The picture is still not clear, Can you throw some light on this? The correct Java virtual machine must be installed for the operating system and hardware. Java bytecode in .class, .jar and .war files is portable. Tomcat is portable. Native code is not portable. The code for installing Tomcat as a Windows service is not portable. If you have installed Tomcat from something other than the zip file (or the .tar.gz file) on the Apache Tomcat site, you may have some native code that you were not expecting. Install from the zip file, start Tomcat via startup.bat and see whether the problem is still there. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I could not find any information in the release notes of the Tomcat 4.1.x versions. 2. Some kind of deadlock or resource (database connections) availability problem which keeps the request handling threads from returning from the doPost/Get method.

As you can see from the threaddump, all 19 threads are waiting to get into the same static synchronized method. I dont understand this because there must be one thread IN the method which holds the lock of the method? Is it possible for a thread to leave a synchronized method without returning the lock? I'm guessing here, never used SingleThreadModel. but I think that what may be happening is the TC for efficiency reasons is creating multiple instances of the servlet otherwise imagine how slow things would be. So its making (MAYBE) 19 instances of the servlet instance and giving each one its own thread so its *still* doing what it promised (1 thread per servlet) BUT... unfortunately for you threads all JOIN again at a STATIC class So if ONE thread gets stuck in .. static synchronized method called removeActiveRoles they ALL do. SingleThreadModel does not fix all threading issues. Maybe time to just make the app thread safe and throw SingleThreadModel away From the loooks of things, threads never come out of *removeActiveRoles* alive ;) br, Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: java.library.path / Unsatisfied Link Error problem with Linux Tomcat 5.5
Solved! I found the source of the problem after following your links below. Not only do you need to place the jar file in the tomcat/shared/lib folder, you need to place the .so there and then adjust the java.library.path on JAVA_OPTS to point there. My .so was originally living in a directory under my user. I also made sure that the .so is owned by the tomcat user and is set for execute privileges. Not sure if all those things are strictly necessary, but certainly the placement of the .so in the shared/lib folder is.

Its only when I deploy to the production version of Tomcat (on the same machine) that this stuff fails. At that point I don't have Eclipse's VM parameter setting abilities available to me and the only place to put it is in JAVA_OPTS.

I have problems to start up Tomcat 5.5 and 6.0. I have downloaded core binary distributions and I have followed the instructions. As a root I have unpacked and moved it to /user/local directory. I have secified the CATALINA_HOME and JAVA_HOME variables. I have set execute permisions to all *.sh files in $CATALINA_HOME/bin/ (chmod ug +x *.sh).

The catalina.log file shows this error message: /usr/local/tomcat-5/bin/catalina.sh: line 273: /usr/bin/java/bin/ java: Not a directory The catalina.sh file line number 273 is: $_RUNJAVA $JAVA_OPTS $CATALINA_OPTS \ I understand the value of JAVA_OPTS or CATALINA_OPTS is /usr/bin/ java and /bin/java. I think something wrong happends, because I had not set either JAVA_OPTS or CATALINA_OPTS. I have tried to set these variables with the value -server -Xmx400m, but the situation has not changed. The error message in catalina.log is the same. I do not understand what happen. Is it possible the problem is for the operation system? My os is Mac os X 10.4.2. Does someone know how I can correct the problem? The problem is this (from your mail) /usr/bin/java/bin/ java: Not a directory Since you set /usr/bin/java as the JAVA_HOME, when it really is the java executable. You have to set JAVA_HOME var to the directory where the entire java installation is, for ex. /usr/jdk1.5.0 I don't know where that could be on Mac os x but do some searching.

RE: Advice about Tomcat on x86_64 architecture..
Thanks a ton Peter, The picture is pretty clear now. Yes i did install the exe and not the zip file. which was creating a problem. Now i uninstalled it and using the zip file, startup.bat , the tomcat runs smoothly. One thing i'm still wondering is the uninstall did not clear the registry entries under Wow6432Node where i had entered the JVM param/ options for Xms Xmx. So 1) if i run the default startup script what is the heap size that is allocated on 64 bit jvm/ OS? 2) How do I specify those sizes using the script? Thanks again! :) Swap. Peter Crowther wrote: From: Swapnil.Kale [mailto:[EMAIL PROTECTED] I tried installing tomcat 32 bit on a 64 bit JVM but it didnt work. That is very unexpected. *Tomcat* is pure Java. I can do a file copy of my entire Tomcat installation and my apps from my 32-bit development box to my 64-bit staging box (and back again) and Tomcat starts and runs without error. Note that I'm using the zip download and starting it from the batch file; I do *not* install a Windows service, and I do *not* use any native libraries. 1) Can i host 32 bit compiled war file on 64 bit Tomcat / JVM ? If my tomcat installation succeeds Yes. I do this regularly. The bytecodes emitted by the compiler are identical whether the compiler runs on a virtual machine on a 32-bit, 64-bit, 36-bit or any other physical hardware. 2) What if i recompile the war on 64 bit jvm and host it on 64 bit Tomcat? Yes. I do this more rarely (my dev box is my usual compile environment), but it works. I repeat: the bytecodes emitted by the compiler are identical whether the compiler runs on a virtual machine on a 32-bit, 64-bit, 36-bit or any other physical hardware. I've read that the size of the primitive datatypes in 64 bit is different, Whoever wrote that is wrong. Java is not C. Java primitive sizes are standard, regardless of the physical machine. so if i use Java web start and launch the application from remote machine 32 bit using JNLP, will it work on that 32 bit machine? having 64 bit machine compiled jars? Yes. If I host the 32 bit compiled war on 64 bit Tomcat / 64 bit JVM, What am i gonna miss/gain? except the lot of heap memory Nothing. The picture is still not clear, Can you throw some light on this? The correct Java virtual machine must be installed for the operating system and hardware. Java bytecode in .class, .jar and .war files is portable. Tomcat is portable. Native code is not portable. The code for installing Tomcat as a Windows service is not portable. If you have installed Tomcat from something other than the zip file (or the .tar.gz file) on the Apache Tomcat site, you may have some native code that you were not expecting. Install from the zip file, start Tomcat via startup.bat and see whether the problem is still there. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/Advice-about-Tomcat-on-x86_64-architecture..-tf4048957.html#a13257088 Sent from the Tomcat - User mailing list archive at Nabble.com. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
PROBLEM POSTING LARGE DATA - TOMCAT6 SSL
Hi, We are having problems posting large chunks of data via tomcat ssl. We are seeing that there is a limitation on how many characters can be submitted depending where the request is coming from. This is happening only when Tomcat is accessed over HTTPS. Problem does not occur when accessing Tomcat directly over HTTP (port 8080). See testing results below... Testing within the server where tomcat is installed/ Total characters successful - 15k out of 15k - there is no limitation. Any thing we post goes thru fine. Testing directly to the server IP or DNS from out side the subnet (My desktop) Max post size successful - 9417 bytes any variable with length more than that fails. All posted parameters show up as null. Testing via F5 (load balanced set up) Max characters successful - 6013 bytes from server and my desktop any variable with length more than that fails. All posted parameters show up as null. Testing directly from server to server within the same subnet (172.28.76.x) Total characters successful - 12663 out of 15k (this one worked partially when set to 15k but only 12663 made it through loosing 3k of data. This was a different result than the rest...in the sense that this is the only scenario where things got posted partially. As you can see something is limiting the amount of character data being allowed as we test from different subnets. SSL puts a load in the data being transfer as well something else, we have adjusted during testing to accommodate for the extra load in order to make work but we have not identify what is limiting are adding additional data to the transfer package.

Re: How to increase Tomcat webserver speed?
keglius wrote: I performed tests on members area and found that in most cases all pages are loaded within 4-10 seconds. The slowest pages (e.g. reports to view longer period time data) sometimes takes 20-180 seconds to load. How can I increase this speed? The obvious approach is to find out where this time is actually spent. The safest approach is to proceed naively from the outside in, as follows. First measure the loading performance of your Web page with Firebug (Firefox Plugin). I will show you which web requests are responsible for the slowdown. Assuming that server response times are responsible for the slowdown (as opposed to the data transfer to the browser), do a real-time profile of the server to find out where the time is spent, e. g. with the Eclipse TPTP or the Netbeans Profiler. Using real-time profiling, you can detect whether the culprits are computations on the server or back-end calls (e. g., to the data base). If server computations are the problem, the profiler will tell you the cause of the problem. If the problem is in the back-end calls, there are two possibilities: (a) The back-end calls consume a lot of time on the back-end server. In this case you must look at the back-end server. If it is a data base server, data base / query optimization must be performed. (b) The data base calls do not consume a lot of time on the back-end server, but their sheer number causes the delays. This requires a redesign of the back-end queries, such that the data is fetched with fewer calls. For example, I have reviewed an application that performed 15.000 DB calls to construct the response to a common user request. No matter how efficient the calls on the data base, the latency of the 15.000 calls will cause a response time in the tens of seconds, at least. Thus, you can find out which of the four most common performance problems is responsible for your delays: (1) Web performance, i. e., too many HTTP requests from the browser (not likely the case here), (2) app server performance, i. e., too many computations, (3) back end performance, i. e., too much work on the back end (e. g., the data base), (4) back end call latency, i. e., too many separate back end calls. It would be premature to start optimizing one of these before having identified the main cause of the problem.

Re: PROBLEM POSTING LARGE DATA - TOMCAT6 SSL
The 6.0.x branch is very stable, ie, there are very few changes going in at the moment. you can build it yourself, by doing: Requirements: a) JDK 1.5 b) ANT 1.6.5+ svn co http://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk trunk cd trunk ant download ant The bug has been present in both 6.0.10 and 6.0.14, so I'd recommend just building yourself, or waiting for 6.0.15.

TOmcat Engine Issue with netscaler
Hi I have an issue with running netscaler with HTTP connetor on 8080. Before the netscaler arrived, I had an apache setup with mod _jk to talk to the two tomcat HOST below 10.7.0.62 and 10.7.0.63 using 8009 connector( Listed is the server.xml of the tomcat box with 10.7.0.61 as primary interface), the Engine defaulthost was 10.7.0.63, and all was working smooth. Now, I created two new Hosts on tomcat of the same two applications above - 10.7.0.62 and 10.7.0.63 ( As I did not wanted to disturb the existing flow, till I get the netscaler working) The two new hosts below are 10.7.0.58 ( same application as 10.7.0.63) and 10.7.0.66 ( same applicatioin as 10.7.0.62), I also brought upto virtual interfaces for them on eth0:1 and eth0:2 with ips 10.7.0.58 and 10.7.0.66. I also changed the defaulthost in the engine to 10.7.0.66. Now the connection between netscaler and tomcats works fine but both applications follow the defaulthost listed under Engine defaulthost which is 10.7.0.66, if I change that to 10.7.0.58, they go to 10.7.0.58. In otherwords, they follow whatever is in defaulthost.

You're trading CPU cycles (running the compression algorithm) for bandwidth. I suspect you're also trading a certain amount of RAM (some extra buffers), though I haven't checked or measured how much so I may be talking out of my hat (as usual). Finally, you may be increasing the time to the first byte arriving back at the client, as you're increasing the amount of output the client has to generate before the first segment of the response is sent. If your servers are CPU-bound, you may not have the spare cycles; if you're tight on RAM, check whether the compression increases the memory use. If you have timing requirements, check that a system with compression enabled still meets them. All that said, a typical business application almost certainly has spare CPU, some spare RAM and no tight timing constraints on the first byte being returned - it's generally bandwidth out of the server and querying the database that are the limiting factors. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Native Library Not found
Ok, I have taken all the posts seriously. I have not ran into a solution. Let me work on the suggestions you provided. I resolved the OOME , but I am worried about scaling users in my server, if tomcat consumes this much memory. As you said since tomcat is not taking the memory I will further investigate as to why the memory gets used this much. Thanks again for all the help provided. Sorry for me being so obtrusive.

I am using tomcat 6 and it has eaten all my memory. Only 56 Mb reamains. Actually, the java process is only taking 285MB of physical memory. The process has allocated just under 1GB of memory, but is not using it at all (since virtual - resident cannot possibly fit into your 108k of used swap, you can tell that nothing has been swapped-out). Some other process has the rest of your 2GB physical memory tied up. top even tells you that your java process is only taking up 14% of your memory. What's the problem? I have a 2GB memory. I have added a connection pool using commons-dbcp and thought that will reduce the probs. How many connections do you have configured? If you were using one connection before, and now you're pooling connections, then you probably are using /more/ memory than before. As I told there is a [Quartz] scheduler running on every minute. Looks like I have some memory leak. Maybe, maybe not. Does your application eventually crash? If so, how? If you turn off the scheduler, does the memory problem go away? What does Java report as the free/total/ma heap values (hint: look at the java.lang.Runtime class). Otherwise why does my machine uses this memory this much. I have an autobuild script running everyday which checkouts from sourceforge cvs , stops the servers, build it and redeploy and start tomcat. So, you are experiencing an OOM before an entire day goes by? Wow. I've never heard of rolling reboots on non-MS-Windows machines. ;) I have not used any tweaks in xml.Should I tune the server to production mode. What is the solution? Why does not the objects get garbage collected.? You have received many, /many/ suggestions from other posters as well as myself. You have followed none of them. We ask you to provide more information and you do not. Instead, you notify us that you are trying some other strategy (switching JVM version, etc.). Finally, you changed your PermGen heap allocation and everything was working again. Are you saying that now you are having problems again? Or, are you simply worried about the amount of memory taken by your application? Java applications simply take up a lot of memory. Complex applications take up a lot of memory.

It's possible that you lack the 32-bit support libraries required by the 32-bit JVM. Is there a 32-bit support package that needs to be installed? I tried following on the mini how to install tomcat on 64 bit OS but didnt succeed. Get the JVM working, first. What i found on internet is we need 64 bit executable for tomcat to run to 64 bit jvm and 64 bit OS offcourse If you are using tcnative, yes, you will need to match your architecture. Tomcat itself is 100% Java, so if the JVM runs, Tomcat will run. Other connectors and stuff may need tweaking, such as tcnative, APR module, isapi redirector, or tomcat.exe -- the MS Windows service binary. All of these are optional. Few Questions : 1) Can i host 32 bit compiled war file on 64 bit Tomcat / JVM ? If my tomcat installation succeeds Absolutely. Your WAR is not architecture-specific. Remember write once, run anywhere? This is what that means. 2) What if i recompile the war on 64 bit jvm and host it on 64 bit Tomcat? Again, the WAR is architecture-neutral, as is Tomcat. Only the OS and JVM have 32-bit and 64-bit versions. I've read that the size of the primitive datatypes in 64 bit is different, You have read incorrectly. Java's primitive types are defined to have specific sizes, regardless of the architecture of the machine on which it is running.

I do not have recent experience with JNDI, so the following are just my guesses, trying to help. May be someone will provide a better answer, or You will be able to find it by yourself. Thus said, it looks to me that what you are trying is not possible.

But beware that: 1) that may conflict with the SecurityManager configuration, if you are using it.

AJP port - How to stop Tomcat from incrementing the AJP port number
When Tomcat 6 finds that the specified AJP port is already in use, it increments the port number and try to bind to the next available port. When this happens, on the web server side apache is not able to connect to the AJP port on Tomcat side, because Tomcat is listening on a different AJP port. So is there a way to make Tomcat listen only on the specified AJP port? In the source I see there is a maxPort variable it is checking while incrementing the port number. Is there a way to control this from configuration files? I am using Tomcat 6 with mod_jk.

Well, it should be possible to do channelSocket.maxPort=0 on the Connector /. However, if the port attribute gets processed after the maxPort, it will reset it back (yes, it's a bug :). If you are using the default 8009 port, then it should be possible to omit the port option on the Connector / and it should work. Shaji Thomas [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] When Tomcat 6 finds that the specified AJP port is already in use, it increments the port number and try to bind to the next available port. When this happens, on the web server side apache is not able to connect to the AJP port on Tomcat side, because Tomcat is listening on a different AJP port. So is there a way to make Tomcat listen only on the specified AJP port? In the source I see there is a maxPort variable it is checking while incrementing the port number. Is there a way to control this from configuration files? I am using Tomcat 6 with mod_jk.

Re: custom web.xml digester call
Auke Noppe [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, Is it possible to call the digester of the web.xml by hand? Like you can override the createstartdigester method in catalina.java? As the other posters have said, it is difficult to see a use case for this. But that isn't a good enough reason to not give you enough rope to hang yourself with :). On the Host / element in server.xml you can specify the attribute: configClass=com.myfirm.mypackage.MyContextConfig (if you are running Embedded, just call the setConfigClass(String) method on the Host object, or set the configClass attribute via JMX if you are using JMX embedding). For any context under that Host, Tomcat will use an instance of this class in place of it's normal ContextConfig class. It only is required to implement LifecycleListener, but if you extend TC's ContextConfig class, then you would need to override the method: protected static Digester createWebDigester() Regards, Auke Noppe No virus found in this outgoing message.

Regards, It sounds like you doing embedded, and yes I thought very much the same way because all the examples call into the embedded routine, and that leaves one wondering how to do things like set up realms, SSL ... and all the good stuff that just happens from config files. What you can do, its what I did and just forget about embedded and call Catalina from your own program based on bootstrap Whats cool is that your embedded program then does exactly what TC does, and you test in TC and then just move the config files to the embedded program. That works so I'm saying instead of trying to jam values in... move up even more and just use the same config files... makes life very easy. Your embedded program will do exactly what TC does... log files are the only exception. Auke Noppe No virus found in this outgoing message. Checked by AVG Free Edition.
