RE: How to send back data without to wait for the complete page.
Stefano, You would probably be better off creating a thread to run this lengthy process in the background and have your Servlet send back a please wait response and refresh automatically after several seconds to check the status until it completes and you can display all of the results. If you're set on doing it though, look for a way to manually flush output from a JSP. I'm not sure how to do that or if you can (I'm sure you probably can, I just haven't ever had the need to do it).

Re: Starting Tomcat w/ commons-daemon
The Tomcat.sh file is meant to be a template for the file that you install in '/etc/init.d'. In particular, it sets the JAVA_HOME variable to where a 1.3.1 JVM would live on a Solaris box (which is most likely the cause of your errors). Most of the other variable will likely need to be modified as well (or you will just start seeing other errors in catalina.out :). If you still have problems after fixing the paths, please post them.

Correct. You need to do 'ls -lL /bin/sh' to be sure. However, if the link is there, I'd guess that what it links to is probably there.

Re: changing class file and reloading question
You can reload using the manager app (the link is on the start page when
you first start tomcat). You can also use an ant target. You can
reload a single webapp, which is probably the better way of doing it.
Here's an example target from a build.xml that takes an arguement:
target name=reload depends=deploy description=Reloads Tomcat
Application (Local)
get src=http://127.0.0.1:8080/manager/reload?path=/${app.name};
dest=status.txt

Look at this example: http://www.chvk.ch/ this is not in english but easy to use.. this is a meta-catalog which permit you to search a book on different libraries. Just type for example cinema in the Titel field (title) and click Starten (start search). You will receive a search result which composed of different html tables, one for each library.

So you added an instance of TestTomcatNotifications to a session as an

events.
You added a listener element to your web.xml registering
TestTomcatNotifications as a HttpSessionListener?
On shutdown sessionDestroyed(...) doesn't get called because the
StandardManager persists sessions and doesn't destroy them.
Let us know if you still don't get the sessionWillPassivate(...) event

So this class logs that some method was invoked only. But when I am shut
down tomcat neither sessionWillPassivate nor sessionDestroyed are been
invoked. In API Doc we can read that:
A container that migrates session between VMs or persists sessions is
required to notify all attributes bound to sessions implementing
HttpSessionActivationListener.
What's wrong?
P.S. I use org.apache.catalina.session.StandardManager implementation.

Re: That ever-popular 'wrong version:46, expected 45' message
The 46 and 45 are magic numbers that the java compiler puts into
byte-code. It looks like you are trying to compile with a older (and
incompatible) version of javac than the servlet classes were compiled
against.
I've seen this before when an installation of Oracle added jdk1.1.8 when
I was already using version 1.3...

RE: directory outside context root
I personally would use the Apache alias. The codes already written for you and through apache the serving of the files should be pretty fast. You don't need to write any servlets or anything then to allow access to these files. It all depends on your project spec.

Re: maxProcessors problem
Hi all. It seems that TC4 has some algorithm which tags objects (read HttpRequests) as long- or short-lived. At 70+ connections per second, I guess most of your HttpRequests would be short lived, which means the gc will reclaim them first, but not until the heap is exhausted. So it might help to allocate more to the short lived requests to force gc to reclaim more often, like this: -XX:NewSize=448m -XX:MaxNewSize=448m This should force the allocation of half the memory to short-lived requests and make gc reclaim more often. You might like to tweak it some more to achieve optimum results ? Please keep us posted on this. Hope that helps.

Does anyone have any examples of Manager Component configuration (which I believe is nested within the Context tags) ? I am using Tomcat 5.0.6 and want to disable the (default) saving of session data that occurs when Tomcat is shutdown. thanks
Tomcat holding problem - CLOSE_WAIT
Hi,
I am trying tomcat-4.1.27, apache2.0.47, mod_jk2.0.2, j2se1.4.2 on Linux9.
I have downloaded tomcat binary. I have compiled apache with ssl, mod_jk2.
I can access dynamic pages which are in tomcat. It works fine. I wanted to
have stress test, so I choose JMeter to test one server page. After few
samples (62) all threads holed by tomcat. It happened to me few times. I
have checked netstat, I found some CLOSE_WAIT.
I can't find the problem, its looks configurations is ok, but I can make
it work.
Any help is appreciated.
Thanks in advance.
Srinivas.

RE: Problem with context.xml and deploying
Thanks for your reaction, but I don't think that bug is related to my problem. This problem is specific to 4.1.x when using a custom context.xml file which forces Tomcat to rewrite the server.xml file. Unfortunately it kind of skips the keystorePass property when rewriting the the server.xml file. Should I report this as a bug?

control own servlets with jmx
hello, i want to control my own servlets the same way tomcat does in the admin-section. how do i do that ? the best solution would be that my servlets implements some interface and i have some methods to access remotely in the servlet class. i first tried to register this servlet in the registry, but i figured out some problems: when jmx tries to load my servlet-class it fails because it doesn't find it. having a closer look to it i found out that there are two ways to register: 1. server.createMBean(mbeanName,mbeanObjectName); then jmx tries to load with an own classloader - but no classloaders are in it 2. server.createMBean(mbeanName,mbeanObjectName,null); then jmx tries to load with the tomcat classloader, but only with that one which accesses the common/lib-directory. my servlet is - as usual - in web-inf/ so i can load classes which are in the common/lib-directory - that works - by the way ! to get a server i'm using the Registry-object from the commons-project - i thought that maybe this is the way to get the right server object, because tomcat uses this one as well - i'm using tomcat 4.1.27 on windows xp. so i have a problem understanding how this could work, because normally i want to access a class already instantiated - a servlet - via jmx. but even my approach doesn't help in this case. thanks, jan

Howdy, Don't think about GC settings as correct or not, as that's too absolute. There's a huge gray area in between that you should experiment with.

RE: maxProcessors problem
Howdy, It seems that TC4 has some algorithm which tags objects (read HttpRequests) as long- or short-lived. Please do tell where you got that impression? ;) At 70+ connections per second, I guess most of your HttpRequests would be short lived, which means the gc will reclaim them first, but not until the heap is exhausted. Not true. They will be reclaimed when possible according to the selected GC algorithm So it might help to allocate more to the short lived requests to force gc to reclaim more often, like this: -XX:NewSize=448m -XX:MaxNewSize=448m This is wrong reasoning, won't force short-lived objects to be reclaimed more often, and you should use a profiler to see that yourself before putting it in a production system ;) The server has 2 GB physical memory and 4 GB swap file. During peak times I'm hitting between 60 and 75 requests per second and it is using pretty close to all of the memory. I've seen the JVM using ~ 830 MB watching top. Don't confuse heap usage with top output, as their variance can be significant (10-20%). top output will always be more than the current heap, as it includes stack, symbol table, translation table, thread, and OS-internal overhead. The ration of top output to heap allocation is very application and OS-specific. Use the Runtime's class freeMemory() and totalMemory() to get a measure of the heap itself. I've set CATALINA_OPTS to use -Xmx896m and -Xms384m. That works fine with maxProcessors set to 384. Problem is, if I set -Xmx higher or maxProcessors higher, I get he OutOfMemoryError. Do you actually get up to 384 processors? Are they all active? Are any hanging? Can you easily reproduce the OutOfMemoryError with JMeter or another stress-testing tool? First off, I'm using RedHat Linux 7.3, IBM JDK 1.4.1, and Tomcat 4.1.24 You might want to update to 4.1.27 ;) I'm trying to get Tomcat to handle a lot of traffic (4-5 million hits per day) and bumping up against a problem I for life of me can't figure out. So, I'm hoping someone else on this list has run into this problem and can help me out! Basically, I can't set maxProcessors higher than 384. If I do, Tomcat We have a system with 512 maxProcessors, using 1G heap, and it's been running fine in production for a couple of months now (stopping only to update tomcat from 4.1.24 to 4.1.27). It's handled up to about 400 concurrent requests, but I picked 512 as the maxProcessors value to leave some overhead for peak times. So 384 is not a magical bottleneck, at least for us, not can I find any code references that would suggest that it is ;) What about your thread limits? All the limits controlled by ulimit? Could it be you're hitting those (the resource constraints part of your error message) as opposed to running out of memory?

RE: minProcessors/max Processors question
Howdy, We are not sure as to why this is happening. I read somewhere that minProcessors/maxProcessors is only for the request processing threads and not for the total number of threads created by tomcat. If this is the What you read is correct. case then, how do we cap the total number of threads being created by Tomcat ? I am concerned that we may run out of memory if this continues. You can't strictly cap the total number of threads created by tomcat, as most of them are not under your control. That's the same as any app server. However, you can take some measurements to reduce the number of threads: - Don't have reloadable contexts if you don't need them - Remove the examples webapp and context Any insights will be appreciated. If you're worried about the number of threads, you're in a good spot. There are a several things that would crash first under a heavy load, before the number of threads becomes an issue ;) Don't use the linux top command as an accurate measurement of the number of threads in the VM, as the JVM thread to OS thread mapping can be more than one to one. Use ulimit or whatever your system's equivalent is to raise the max number of threads allowed for the user that runs tomcat.

Re: About heap size, gc and newsize
I guess the real question is why are you concerned with when the requests are GC'd. Left to it's own devices, GC usually only happens when the JVM is using almost all of the allocated memory. Therefore, the more memory allocated, the longer till GC and the longer GC will last. If you are trying to get it to run more often so that it takes less time, take a look at 1.4.2. --- Bill Barker [EMAIL PROTECTED] wrote: At least in Tomcat, the HttpRequests aren't short-lived ;-).

Connecting to MySql. Cannot load JDBC driver class 'null'
Hi there, I hope this to be useful to somebody. I installed Tomcat 4.1.24 y MySql 3.23 en Linux Red Hat 8.0 Followed the steps within jakarta page: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-how to.html in order to get connected to my database. However, I found the next error: Cannot load JDBC driver class 'null'. After some troubleshooting, I finnaly got with two problem causes: 1. For some reason, Mysql's JDBC Driver tries to connect to localhost.localdomain. Which means, that when you specify into the connection string (in my case) jdbc:mysql://localhost:3306/DBPrueba java tries always to connect to localhost.localdomain. I solved this problem assigning permission to the Database in Mysql for my test user, only that this time for different domain: GRANT ALL PRIVILEGES ON DBPrueba.* TO 'administrator'@'localhost.localdomain' IDENTIFIED BY 'passwd'; 2. Tha Database version I'm using doesn't recognize the default parameter used by Resource within server.xml, to setup JDBC driver manager. Which for I had to modifify the next lines: parameter namedriverClassName/name valueorg.gjt.mm.mysql.Driver/value /parameter for these ones: parameter namedriverName/name valueorg.gjt.mm.mysql.Driver/value /parameter The steps I made here are an adition over the manual found in Tomcat web page.

Furthermore, all the java processes are started under user root. Is there a way to start the java processes under another user?

RE: About heap size, gc and newsize
Howdy, Left to it's own devices, GC usually only happens when the JVM is using almost all of the allocated memory. Therefore, the more memory allocated, the longer till GC and the longer GC will last. ;( ;( This is a common wrong assumption people have about Java's modern GC algorithms. In fact, they run all the time, even when not configured to use the incremental (or train) collector. With all the default VM settings, GC scanning and reclaiming for a typical application will happen often, long before the heap is largely allocated, frequently more than once a second. This is pretty easy to see if you enable -verbose:gc flag to the JVM.

RE: Installing Tomcat as a Service
Stuart, You basically need to write a wrapper .sh script to tart tomcat and put it into the init.d directory. The init.d directory varies with the linux distro but common places a /etc/init.d and /etc/rc.d/init.d. Then you need to create sym links to start/stop it on the various run levels. I refer you to your documention on services under RedHat. I believe that somebody mentioned that there is a catalin.sh script that works as a service, so you may not need to write one. In most of the RedHat distros that I have used, there is a script in the init.d directory named httpd that takes care of stopping and starting apache as a service.

Re: high memory usage ....
I believe many other of you have encountered the high memory usage with tomcat? Is there a way to decrease the amount the java processes use? yes, take a close look at the Tomcat configuration reference (Connectors) Furthermore, all the java processes are started under user root. Is there a way to start the java processes under another user? This has been discussed approx. 2874438 times on this list ;-) Any particular version of java and/or tomcat adviced to deal with these problems? In general, memory comsumption is likely to decrease with newer JDKs. I also noted a noticeably startup speed improvement using 1.4.2 - but YMMV depending on deployment needs/restrictions. It might also be worth trying JDKs from different vendors. Regarding TC versions: always try to stay as up to date as possible - there are lot of continuos improvements regarding speed, stability, memory consumption and of cause fixed bugs. Additionally, TC5 has seen a lot of improvements regarding its inner workings resulting in better overall speed and less memory consumption. I guess auditing the java applications which are written is also very nice to do and fixup some memory leaks if they're there? There a lot of different tools (commercial and OSS) available, just do a search on google. Yann - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

But tomcat still isn't starting, and I am not receiving any other errors.
Also the script executes fine when I do it from command line. I have placed
the start/stop script in /sbin/init.d/. I have made the script be last to
start and first to stop. I couldn't get the script to recognize the env
variables when they were in the rc.config.d directory, so I placed them
directly in the script which seems to have worked, but the process still
isn't starting.
Can anybody give me any other ideas as to what could be wrong or what I
could try? Any ideas how I can get a better error information?

Subject: RE: Starting tomcat from init scripts (HP/UX)
Have a look at /usr/share/doc/start_up.txt or /usr/share/doc/start_up.ps on
a HP-UX 11.00 machine
for details of how to write a startup script conforming to HP-UX's standards
(for issuing messages
at startup and shutdown via the 'start_msg' and 'stop_msg' parameters,
honouring the settings in
/etc/rc.config.d etc...).
You can use any of the scripts in /sbin/init.d as a basis - modify one as
appropriate and
get it to simply call catalina.sh.
We also modified our catalina.sh to check which userid was calling the
script. If it was root it would sudo to the non-privileged user that Tomcat
ran under ('tomcat'). If it was userid 'tomcat' calling it it would simply
continue. If it was anyone else, it would exit with an error message. This
way we get Tomcat started as a non-privileged user
starting automatically on boot.

Quickly get Tomcat running with Apache on Solaris?
Solaris 9 has Apache and Tomcat loaded by default. I
got Apache running but Tomcat needed more work. So I
tried to download it from Jakarta at:
http://apache.oregonstate.edu/jakarta/tomcat-4/binaries/
I gunzipped it and un-tarred it. Then I did what it
said to do in the docs...
* Unpack the binary distribution into a convenient
location so that the
distribution resides in its own directory
(conventionally named
jakarta-tomcat-4.0). For the purposes of the
remainder of this document,
the symbolic name ${catalina.home} is used to refer
to the full
pathname of the release directory.
(2) Start Up Tomcat 4.0
There are two techniques by which Tomcat 4.0 can be
started:
* Via an environment variable:
- Set an environment variable CATALINA_HOME to the
path of the directory
into which you have installed Tomcat 4.0.
- Execute the shell command:
%CATALINA_HOME%\bin\startup (Windows)
$CATALINA_HOME/bin/startup.sh (Unix)
* By modifying your current working directory:
- Execute the following shell commands:
cd %CATALINA_HOME%\bin (Windows)
startup (Windows)
cd $CATALINA_HOME/bin (Unix)
./startup.sh(Unix)
NOW - It won't run. I'm not even sure it was a Solaris
Binary.
This is what I get in the catalina.out file:
$ cat catalina.out
Exception in thread main
java.lang.NoClassDefFoundError:
org/apache/catalina/startup/Bootstrap
Whats the easiest way to get Tomcat running with
Apache on Solaris 9?

RE: maxProcessors problem
Have you verified that at the time of the Out of Memory errors that the JVM is somewhere near 896M RAM? How about when it starts up and there is little or no traffic? Is it at or above (probably above) 384M? It usually has 160 MB to 220 MB of memory allocated (these figures are from top, so room for some error). The system is under pretty heavy traffic when it starts up. I have maxProcessors set to 384 and minProcessors set to 50. Since you have free system RAM left, then it sounds like your 896M is too small for the load. Problem is, if I increase -Xmx and don't touch anything else, I get this OutOfMemoryError too. The system has 1.2 GB to 1.4 GB of memory free when this error occurs. Do you load balance Tomcats across machines? Or are you running all these users against one Tomcat? Just one Tomcat and MySQL on the server.

Tomcat cannot find subclass
I am having a problem with Tomcat 3.3, running on Solaris 8. I have written a framework for asking questions and getting responses through a browser.

mod_jk2 load balancing as a RAID 0+1 analog
Hi all, Here is my configuration: Front-ent - Apache 2.0.47/mod_jk2/ajp13. 4 instances of JBoss 3.2.1/Jetty 4.2.11 with identical ear applications are configured as 2 pairs of fail-over clusters with distributable/ webapp. node1+node2 creates a first fail-over cluster. node3+node4 creates a second fail-over cluster. Initial http request can go to any of these 4 nodes. After that mod_jk2 should redirect subsequent requests inside the initial fail-over cluster, and only if both nodes in that cluster fail, try to redirect to another nodes. The problem here is that I do not know is it possible to configure mod_jk2 (workers2.properties) to redirect this way. Any ideas are highly appreciated.

Re: Tomcat cannot find subclass
Yes, the jar was in WEB-INF/lib, and I took it out in case that was a problem. There was no change in the result when I did. I also suspect a ClassLoader issue. What I would like to know is why? When I subclass a member of a framework, do I have to put my project-unique subclass in the same jar as the common classes?

Subject: Quickly get Tomcat running with Apache on Solaris?
Solaris 9 has Apache and Tomcat loaded by default. I
got Apache running but Tomcat needed more work. So I
tried to download it from Jakarta at:
http://apache.oregonstate.edu/jakarta/tomcat-4/binaries/
I gunzipped it and un-tarred it. Then I did what it
said to do in the docs...
* Unpack the binary distribution into a convenient
location so that the
distribution resides in its own directory
(conventionally named
jakarta-tomcat-4.0). For the purposes of the
remainder of this document,
the symbolic name ${catalina.home} is used to refer
to the full
pathname of the release directory.
(2) Start Up Tomcat 4.0
There are two techniques by which Tomcat 4.0 can be
started:
* Via an environment variable:
- Set an environment variable CATALINA_HOME to the
path of the directory
into which you have installed Tomcat 4.0.
- Execute the shell command:
%CATALINA_HOME%\bin\startup (Windows)
$CATALINA_HOME/bin/startup.sh (Unix)
* By modifying your current working directory:
- Execute the following shell commands:
cd %CATALINA_HOME%\bin (Windows)
startup (Windows)
cd $CATALINA_HOME/bin (Unix)
./startup.sh(Unix)
NOW - It won't run. I'm not even sure it was a Solaris
Binary.
This is what I get in the catalina.out file:
$ cat catalina.out
Exception in thread main
java.lang.NoClassDefFoundError: org/apache/catalina/startup/Bootstrap
Whats the easiest way to get Tomcat running with
Apache on Solaris 9?

Re: Tomcat cannot find subclass
Unlike Tomcat 4, Tomcat 3 uses a delegating ClassLoader. This means that jars in lib/apps can't see classes in WEB-INF/classes. Also, as long as the jar is in lib/apps, Tomcat 3 will load classes from there in preference to the same jar in WEB-INF/lib. James C. McMaster (Jim) [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Yes, the jar was in WEB-INF/lib, and I took it out in case that was a problem. There was no change in the result when I did. I also suspect a ClassLoader issue. What I would like to know is why? When I subclass a member of a framework, do I have to put my project-unique subclass in the same jar as the common classes?

Problem, can't get response form tomcat after some requests
Hi All,
I have installed tomcat4.1.27, apache2.0.47, modjk2.02, and j2se1.4.2 on
Linux 9. I have compiled Apache, mod_jk2 from the source.
After several requests from JMeter, tomcat simply holds up, no more
requests can be processed by tomcat.
I can't stop tomcat unless I kill the tomcat process. I have restarted
apache, it doesn't help.
I found some CLOSE_WAIT after I restart apache. I have killed tomcat, all
CLOSE_WAITs are gone.
Same thing is repeating again and again after I start tomcat.
I can't figure out the problem. I have posted my configuration here.
Can any one find where I am doing mistake?
I am straggling since few days.
Help would be appreciated.
Thanks in advance.

Hi, We are using tomcat 4.1.24. The server.xml has configuration for http and https. Now if user wants to disable http and use only https, is there a way to do that in server.xml. One way is to comment the config of http is server.xml But we don't want to pursure in this direction. Is there any property we can set in server.xml to disable htpp or https based on user preferece.

classpath issues and system properties
Hi, I am using tomcat 4.1.24. I have a couple of questions. 1. Online documentation about class loader says, System class loader operates on CLASSPATH. I have included j2ee.jar in my CLASSPATH, but tomcat is not picking it up. Why is it so? 2. When I use tomcat, system property java.naming.factory.initial is initialized to org.apache.naming.java.javaURLContextFactory. Where did the system pick this property from? How can I override this setting? I initialized JNDI context with environment having java.naming.factory.initial as com.sun.enterprise.naming.SerialInitContextFactory but ultimately org.apache.naming.java.javaURLContextFactory is set to java.naming.factory.initial. How can I avoid this? I would appreciate if anybody can help me with these issues. I am really struggling for a week. tia, Srinivas = I am not afraid of losing. But I don't like it. __ Do you Yahoo!?

I then do the following with chkconfig:

Thanks for your advices. The error is that files

But I meet the following problem:
- I use the mysql supported already by Redhat Linux
7.3 O/S to store my database.
- The jakarta-tomcat-3.2.4 is used to be the server.
- I use mysql-connector-java-3.0.6-stable-bin.jar for
connection between mysql and JSP.
- I put the my web application in the directory:
jakarta-tomcat-3.2.4/webapps/myapp.
- I put the mysql-connector-java-3.0.6-stable-bin.jar
in directories: jakarta-tomcat-3.2.4/lib, and
jakarta-tomcat-3.2.4/webapps/myapp/WEB-INF/lib

Hello,
seems like
/bin/sh
does not exist. I saw the same problem in
another
mail today.
Please check if /bin/sh exists and is
executable. It
really should!
regards,

Re: Exception get SSL attributes - SSLPeerUnverifiedException: peer not authenticated.
I just ported the patch from the j-t-c HEAD. Yes, the error is harmless (except for the disk space it takes up :). TC 4.1.28 should be quieter. If you need it sooner, then you can grab it from the CVS and re-compile.

Re: maxProcessors problem
Not true. They will be reclaimed when possible according to the selected GC algorithm Aha, are there actually different reclamation algorithms that I can select from ?? I mean, like some parameter in catalina.sh ?? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
