TomCat and support of WebServices stacks: JAX-WS vs. Axis
Which type of WebService stacks does TomCat support-out-of-the-box (=without installing additional components): JAX-WS and/or Axis Assume I get to a remote server where TomCat is running. How can I check what types of WebServices (and which spec version) are currently supported by this Tomcat installation?

Re: CPU usage quirk with multiple tomcat instances
We dont have synchronisation issues - I've already profiled extensively with jprofiler.. Well we did, but after using jprofiler we dont :) Err, I think our app is the same as yours :) What im saying is that for the same load the machine uses more cpu with 2 tomcat instances... So i guess that is correct, i was just looking for why!

Two instances : less code in same block and vm, effectively less synchronization. try to profile whether some use cases take longer on the single tomcat per machine. We once tried to run multiple tomcats on one machine and the results where opposed to yours: less performance, so i think your app behaves funny :-) regards Leon On Fri, May 2, 2008 at 2:42 PM, Lists [EMAIL PROTECTED] wrote: Hi, We have a Tomcat app that is loadbalanced by hardware. I have 4 boxes available in our test env, all of which vary slightly but not massively in spec. Anyway I moved from 2 tomcat instances on each machine ( listening on different ports ) down to 1 and I noticed for the same load the cpu utilisation dropped by 20%. Interesting, how can this be explained? Is this the extra effort in tomcat or something? Or is it memory related? the 2 instances had 1gb each, and the single one has been given 4gb. However I have jprofiled the instance and it has never seemed memory hungry. Anyway I suspect even at 2gb for 1 instance it would still be 20% less cpu - i can always do a run to prove this if people think that necessary.. Another thing i've found is that on one server I have abnormally high CPU utilisation for the same load. I've checked the logging levels are all the same as are the java VM and the VM config settings. I wonder what else could cause this? All i can think is some sort of OS or hardware malfunction! maybe the CPU cache is duff or something. Many thanks to any input to my Friday weird-ness!

RE: Installing tomcat on multiple cpu X_86 64 bit machine
From: sur_1805 [mailto:[EMAIL PROTECTED] now. can i install the tomcat5.5 and jdk1.5 on machine(4 processor with 64 bit on RHEL 5) without need to worry about load balancing and tuning at the time of installation? Yes, in the same way that you can install (say) Apache httpd and PHP without worrying about load balancing and tuning at the time of installation. It'll work; it may not be ideal, but you can clean up later once you find out what the application *really* does. - 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]

You could always try this:

#include string.h
#include stdlib.h
#define MAX_ERROR_STRING_LENGTH 1024
int main(int argc, char *argv[]) {
~ int error_num;
~ char error_msg[MAX_ERROR_STRING_LENGTH];
~ if(argc 2) {
~printf(Usage: %s errno\n, argv[0]);

~ strerror_r(error_num, error_msg, MAX_ERROR_STRING_LENGTH);
~ printf(Error %d: %s\n, error_num, error_msg);
~ return 0;
}
Also, if you are using MySQL, it comes with a perror program that
basically does what the above does (but also reports MySQL error
numbers, too). Not sure if that's included in the win32 build, though.

Problems with Java Security Manager
Hi All,
Can someone check my reasoning here? I am having difficulty with the Java
Security Manager. I am encountering the following 2 exceptions with some of my
servlets :
I am running :
Tomcat 4.1
Apache/1.3.33 (Win32)
mod_jk/1.2.8
JRE Version 1.4.2_03
I have enabled security manager logging using the following Java option (I've
set this in the configuration dialogue box for Tomcat as I'm running Tomcat as
a service on NT)
set CATALINA_OPTS=-Djava.security.debug=access,failure
Exception #1 (generated when using RMI):
access: access allowed (java.util.PropertyPermission java.rmi.server.hostname
read)
access: access allowed (java.util.PropertyPermission
sun.rmi.transport.connectionTimeout read)
access: access allowed (java.util.PropertyPermission
sun.rmi.transport.tcp.handshakeTimeout read)
access: access allowed (java.util.PropertyPermission
sun.rmi.transport.tcp.responseTimeout read)
access: access allowed (java.io.FilePermission
C:\Tomcat41\server\lib\tomcat-util.jar read)
access: access allowed (java.io.FilePermission
C:\Tomcat41\server\lib\tomcat-util.jar read)
access: access allowed (java.io.FilePermission
C:\Tomcat41\server\lib\tomcat-util.jar read)
access: access allowed (java.util.PropertyPermission socksProxyHost read)
access: access denied (java.net.SocketPermission XX.XX.XX resolve)
Exception #2 :
java.security.AccessControlException: access denied
(java.util.PropertyPermission catalina.base read)
I presume that the above 2 exceptions are generated by the Java Security
Manager. I have tried the following in my
catalina.policy file
grant codeBase file:${catalina.home}/webapps/mywebapp/- {
permission java.security.AllPermission;
};
but it makes no difference.
Also, I am wondering why catalina.base should have a problem reading files (I
am running Tomcat as Administrator)
These problems are happening in the test environment, but on the live system
there are no such exceptions being generated. I can't figure out why this
should be the case as the java.policy and catalina.policy files in the
Catalina.home/conf directory are identical for both live and test environments.
Does anybody know how to disable the Security Manager for Tomcat when running
as a service in NT or is it disabled by default?
Many thanks in advance,
Jonathan O'Donovan

shared libs, but non shared static object instances between multiple webapps?
Hi Is it possible to have shared libs between multiple web applications (context's) in tomcat (6.0.x), where the static instances (like singletons) are not shared? I used following feature in catalina.properties, which successfully loads the libs from the same path for each webapp: shared.loader=$INSTALL_PATH/core/conf,$INSTALL_PATH/core/*.jar,$INSTALL_PATH/core/lib/*.jar But unfortunately (for us), all the singleton objects (based on static var) are now shared too, which seems logical as the classloader probably loads only one instance of the jars/classes for the whole tomcat container. The motivation for doing this is that we have many projects on one server which run under the same tomcat, and which should run the same software/jar release (defined in shared.loader), only different configuration files. This would allow to update the software for all projects by updating the libs in our core systems, which is only installed once per server. Before we had to update each project's WEB-INF/lib separately, and over 100MB of libs were duplicated per project. Any hope achieving this easily (like configure separate classloaders?), without having to remove all singletons ? Besides, having an empty 'WEB-INF/lib' brought some other strange changes: Following code did not find property files in the Classpath (WEB-INF/classes), whereas before (with all our libs in WEB-INF/lib) it worked : InputStream propertyResource = getClass().getResourceAsStream(filename); Seems the tomcat (java?) classloader is reacting specially in that case, like shortcutting it's ressource search?!

Especially cping/cpong are helpful in early problem detection. The pool timeouts should be helpful for closing idle connections, before you get a connection drop. Try to understand the page, and if things are unclear, ask us. How do you know, that the firewall is the root cause? To get a better understanding for the situation, you could compare netstat -an on the apache httpd side with one on the tomcat side. Look only for the relevant ports (8007 resp. 8009) and look for differences between the output. There could be small differences for a short period of time, but there should be no connections missing or being in a different state between the two outputs for a longer time (except for TIME_WAIT).

For example does this work: worker.balancer.type=lb worker.balancer.balanced_workers=worker1,worker2 worker.balancer.mount=/context Yes, that's how it works. But this will only map the exact URL /context, not /context/myservlet. So usually you also want to mount /context/*. The mount directive can be used multiple times. If you use a load balancer worker, in fact you should mount via the balancer and *not* via its member workers. On the docs page http://tomcat.apache.org/connectors-doc/reference/workers.html in the table, where the mount attribute is explained, the seconds columns says AJP,LB, which means, you can use it for workers of type LB (if you don't use an LB) or for LB workers. The missing SUB indicates, that you should not use it for sub workers of an LB. Using the mount atribute is not common. Most people either use a uriworkermap.properties file (and JkMountFile in Apache httpd), or directly JkMount in httpd. But those ways of defining mounts are basically equivalent. JkMountFiles contents can be changed without web server restart and JkMount directives in httpd.conf are a little closer to the other context related httpd configuration items.

Another (perhaps Linux-specific?) way to get some information is to run ps -fLp 12345 (where 12345 should be the PID of your Tomcat process). This will show one line for each thread in the Tomcat process, and also will show the amount of CPU time used by each thread. If you run this a couple of times, you should be able to pick up threads with significant increase in the used CPU time. These can then be correlated with the thread dump. F.ex. in my toy machine, the thread taking the most of CPU time is: tomcat7035 1 7870 0 40 Feb13 ?01:08:37 /usr/lib/jvm/java/bin ... where 7035 is the process id of Tomcat, and 7870 is the thread id. The thread dump then tells what that thread is running - however, the thread dump lists threads by hexadecimal id, and the above is decimal, so a conversion is needed: 7870=0x1ebe . Now to look for that 1ebe in the thread dump: ContainerBackgroundProcessor[StandardEngine[Catalina]] daemon prio=1 tid=0x08366728 nid=0x1ebe waiting on condition [0xb135c000..0xb135cfa0] at java.lang.Thread.sleep(Native Method) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1597) at java.lang.Thread.run(Thread.java:595) so, on this machine (a toy, as I said), the thread with most accumulated CPU usage has been ContainerBackgroundProcessor - which was sleeping at the time of this thread dump.

Especially cping/cpong are helpful in early problem detection. The pool timeouts should be helpful for closing idle connections, before you get a connection drop. Try to understand the page, and if things are unclear, ask us. How do you know, that the firewall is the root cause? To get a better understanding for the situation, you could compare netstat -an on the apache httpd side with one on the tomcat side. Look only for the relevant ports (8007 resp. 8009) and look for differences between the output.

Prerequisite : TOMCAT 5.5.23 (already in production ,we cannot change this version) 2 nos JSDK : 1.6 O/s : windows 2000 With regards Karthik a) Clustering 1) Do we need to deploy the war files on each individual Tomcat when joined the clustering. deploy your apps only to one server, and the cluster will distribute the deployments across the entire cluster. This does not seems to work, after following the steps for 2 Tomcats (or am i missing some thing in here.) 2) Is this a must do configuration Make sure that all nodes have the same time and sync with NTP service! for the clusters to start functioning.
