Fwd: Problem, can't get response form tomcat after some requests

[Venkata Srinivasa Rao, Yerra]

Dear All,

Tomcat works fine for

1. Java HotSpot(TM) Server VM (build 1.4.2-b28, mixed 
mode) on Linux 9 without NPTL (LD_ASSUME_KERNEL=2.4.1)
2. Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed 
mode) on Linux 9 with NPTL

Tomcat process simply ceases to respond after some requests from 
JMeter

1. Java HotSpot(TM) Server VM (build 1.4.2-b28, mixed 
mode) on Linux 9 with NPTL

Any idea?

J2SE 1.4.2
Tomcat4.1.27
Linux 9
Apache2.0.47
mod_jk2.0.2

Srinivas.

Subject: Problem, can't get response form tomcat after some requests
X-Spam-Rating: daedalus.apache.org 1.6.2 0/1000/N
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.

Regards,
Srinivas

Wherever you saw these docs, they are wrong.  Tomcat ignores the CLASSPATH
variable.  And, in any case, trying to use j2ee.jar with Tomcat is pure evil
;-).  Just install the components that you need, and you may finish your
project in finite time :).

I don't believe that you can avoid it (without looking more deeply into the
code than I care to do at the moment).  And, even if you could, the likely
result is that Tomcat would lay on it's back, point it's toes in the air,
and die.

Re: Tomcat 4.1 DefaultContext Bug?

The main problem I think is that Velocity requires files. You supply the 
directory, and it accesses them from the filesystem. If you don't unpack 
Velocity can't find its files. There is probably a way around this so that 
Velocity can use the war directly, however I was hoping to simply migrate 
from 4.0 to 4.1, and was hoping it would just be a minor configuration issue 
to get it going.

I've read the 4.1 documentation, and from what I can see the specification in 
terms of the DefaultContext hasn't changed, although they are definitly 
behaving differently. Perhaps its time to look at the code :)

Re: Server.xml

[Bill Barker]

Of course, one way is to comment out the http connector.  The other way is
to include a security-constraint in your web.xml something like:
  

   SSL area
   /protected/*


  CONFIDENTIAL

  

This forces all URLs under /myapp/protected to use SSL to process them.  Of
course, modify the url-pattern to match your use case.

You can only configure this per-directory with Tomcat-out-of-the-box.  To
configure this per-user, you would need to write your own Filter to do this.

Re: Exception get SSL attributes - SSLPeerUnverifiedException: peer not authenticated.

[Bill Barker]

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: Error when I start Jakarta-tomcat(Cont) - Error when I load file

[Luong Phan]

Hi all,

Thanks for your advices. The error is that files
startup.sh and shutdown.sh are not executable. Now I
can start Tomcat.

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 
- I create a properties file (myprop.prop contains
DBURL, DBUserName, DBPassword, and DBDriver) and put
it at directories: jakarta-tomcat-3.2.4/bin, and
jakarta-tomcat-3.2.4/conf.

After I start mysqlserver and tomcat, I type on the
Mozilla browse: http://localhost:8080/myapp, the
browser display my web page. When I link to a URL that
call the JSP program:


import java.io.FileInputStream;
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Enumeration;
import java.util.Properties;


public class MyData {
private Connection connection;  
private Statement statement;


public MyData() throws
ClassNotFoundException,SQLException{

String DBDriver=null;
String url=null;
String username=null;
String password=null;

Properties props = new Properties();
String pFile="myprop.prop";
try {
props.load(new
FileInputStream(pFile));
} catch(IOException e) {
System.err.println("Failed to load
property file");
}
   ...
I get the following massage "Failed to load property
file".

Please help me!

Thank you very much.

Looks like it is complaining about the path.  Have you tried using C:\edevis
instead of C:/edevis for your appBase and docBase?

RE: Installing Tomcat as a Service

[Mike Cherichetti \(Renegade Internet\)]

I use the following script on RedHat 7.3 (I save this as
/etc/rc.d/init.d/tomcat):

#!/bin/bash
#
# Startup script for the Tomcat Web Server
#
# chkconfig: 345 84 16
# description: Tomcat is a World Wide Web server.  It is used to serve \
#  HTML, JSP, and servlets, and CGI if needed.
# processname: java

case "$1" in
  start)
$CATALINA_HOME/bin/startup.sh
;;
  stop)
$CATALINA_HOME/bin/shutdown.sh
;;
  *)
echo $"Usage: tomcat {start|stop}"
exit 1
esac

exit 0

I then do the following with chkconfig:

chkconfig --add tomcat
chkconfig --level 345 tomcat on
chkconfig --list tomcat

If that still doesn't work, ensure that you've set CATALINA_HOME and
JAVA_HOME in /etc/profile.

Hope that helps,
Mike

Thanks for the reply, I've tried creating a script in the /etc/init.d
directory and then running the chkconfig --add script-name and this hasn't
worked for me.

I'm getting an error saying that:
service service-name does not support chkconfig

I must still be doing something wrong?

The script has the same permissions showing in the ls -l list?

For a Java program, write a wrapper shell script like Tomcat authors did
with
catalina.sh.

classpath issues and system properties

[srinivas reddy]

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.

Server.xml

[Sarika Inamdar]

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.

Please help me on this.

Thanks Much in Advance,
Sarika

Re: Tomcat 4.1 DefaultContext Bug?

[Kwok Peng Tuck]

Specifically what problems do you have when running the app as a  war 
file  ?

Peter Harrison wrote:

I have spent the last three days trying everything to move from 4.0 to 4.1. 
The problem is with the datasources. When the resource is in a specific

problem however is that a Context that is specified will block unpacking of a

I need to define the datasource in the DefaultContext. However this isn't 
working.

Simply changing from DefaultContext to Context "solves" the problem - proving

Problem, can't get response form tomcat after some requests

[Venkata Srinivasa Rao, Yerra]

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.

Re: Tomcat cannot find subclass

[Bill Barker]

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.

Re: Starting tomcat from init scripts (HP/UX)

[Tim Funk]

1 - You classpath is probably wrong - it should be tiny to allow dynamic 
classloading so classes may be reloaded
2 - Try using startup.sh, here is an easy way:
cd /bto/appl/apache/jakarta-tomcat-4.0.4 && bin/startup.sh
instead of catalina.sh.
3 - Temporarily - hack the startup scripts to print crap to standard out so 
you can trap the error messages for more information
4 - There should be error messages somewhere - but do the above since they 
can't seem to be found

Using CATALINA_BASE:   /bto/appl/apache/jakarta-tomcat-4.0.4
Using CATALINA_HOME:   /bto/appl/apache/jakarta-tomcat-4.0.4

Using JAVA_HOME:   /opt/java1.4
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?

Below is the start/stop script - /sbin/init.d/tomcat.  Can you see anything

RE: Quickly get Tomcat running with Apache on Solaris?

What's your CATALINA_HOME set to?
Did you use GNU Tar to unpack it? (Solaris default tar will likely muck up
the extract)

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? 

Thanks!

Is this mistyped?  Above, you have "CountrySelectServlet..." not found, but 
you say it's actually called "CountryServletSelect..." (Servlet and Select 
are swapped), so it's right that it not be found.

  I checked yesterday after looking through old message on this
archive and I don't see how that can be the problem.  I have precisely
two copies of the tools.jar file, one in my j2sdk1.4.2, and one in my
Tomcat4.1.27 directory.  Each is 4.85 M, and contains 1373 (or
whatever) entries.  They are, as far as I can tell, new, current, and
entirely identical.
  If they aren't -- if I have missed some subtle difference -- which
one should be consigned to oblivion?

It's not about permissions, it's about the format of the script. From the 
chkconfig man page:
-
RUNLEVEL FILES
   Each  service which should be manageable by chkconfig needs two or more 
commented lines added to its init.d
   script. The first line tells chkconfig what runlevels the service 
should be started in by default, as  well
   as  the start and stop priority levels. If the service should not, by 
default, be started in any runlevels,
   a - should be used in place of the runlevels list.  The second line 
contains a description for the service,
   and may be extended across multiple lines with backslash continuation.

   For example, random.init has these three lines:
   # chkconfig: 2345 20 80
   # description: Saves and restores system entropy pool for \
   #  higher quality random number generation.
   This says that the random script should be started in levels 2, 3, 4, 
and 5, that its start priority should
   be 20, and that its stop priority should be 80.  You should be able to  
figure  out  what  the  description
   says; the \ causes the line to be continued.  The extra space in front 
of the line is ignored.
-

Make sure your script has this line and ALL three numbers are present (read 
above to figure out what they are):
# chkconfig: 2345 20 80

Re: Tomcat cannot find subclass

[James C. McMaster (Jim)]

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?  If so, that really sucks.

Have you tried placing your library in WEB-INF/lib?

mod_jk2 load balancing as a RAID 0+1 analog

[Vladyslav Kosulin]

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  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.
Thanks,
Vlad

Tomcat cannot find subclass

[James C. McMaster (Jim)]

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.  The package is called com.stortek.ilm.userresponse.  The classes 
live in a .jar file which resides in $TOMCAT_HOME/lib/apps.

One of the classes in that package, ServletSelectAnswerFormatter, generates 
an HTML select.  I get the options by invoking a method designed to be 
overridden in a subclass.

My current project has such a subclass, CountryServletSelectAnswerFormatter, 
which resides in WEB-INF/classes/com/stortek/ilm/userresponse for the correct 
context.

When the servlet runs, I get a ClassNotFoundException:

Class not found: com.stortek.ilm.userresponse.CountrySelectServletAnswerFormat
ter

Does anyone know what is wrong?  Is it possible to subclass part of a 
framework, and store the subclass and its parent this way?

Thank you for any help you can provide.

Exception get SSL attributes - SSLPeerUnverifiedException: peer notauthenticated.

[Chris Massam]

Hi there,

Since upgrading from Tomcat4.1.24 to 4.1.27 I have been seeing these 
again in the catalina.out log.
I seem to rememeber this being present in a previous build (4.1.13 prehaps).

I'm running JDK1.3.1_06 with JSSE extensions.

This dosn't seem to be causing any problems - just a 20MB log file per day!!

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.

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.

Just one Tomcat and MySQL on the server.

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?

Since you have free system RAM left, then it sounds like your 896M is
too small for the load. Do you load balance Tomcats across machines? Or
are you running all these users against one Tomcat? If  you could spell
out the setup in a bit more detail, I might be able to help you figure
it out and possibly how to fix it.

Quickly get Tomcat running with Apache on Solaris?

[Jim Chase]

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? 

Thanks!

RE: Starting tomcat from init scripts (HP/UX)

[Lott, Carey]

Since nobody has responded does this mean nobody has any more ideas on the
problem or am I getting the "You idiot.  The answer is staring you in the
face." silent treatment?  If it is the latter, I will admit being an idiot
if someone will enlighten me.  If it is the former, I want to say thank you
for the help I have received to this point because I am farther along then I
was, and if I figure out a solution short of a cron entry I'll post it.  
Thanks again for the help.

Subject: RE: Starting tomcat from init scripts (HP/UX) 


Ok, I finally got the script to execute correctly and I got the familiar
output:

Using CATALINA_BASE:   /bto/appl/apache/jakarta-tomcat-4.0.4
Using CATALINA_HOME:   /bto/appl/apache/jakarta-tomcat-4.0.4
Using CATALINA_TMPDIR: /bto/appl/apache/jakarta-tomcat-4.0.4/temp
Using JAVA_HOME:   /opt/java1.4

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?

Below is the start/stop script - /sbin/init.d/tomcat.  Can you see anything
missing?

Thanks in advance for everybody's input and help.

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.

 I checked yesterday after looking through old message on this
archive and I don't see how that can be the problem.  I have precisely
two copies of the tools.jar file, one in my j2sdk1.4.2, and one in my
Tomcat4.1.27 directory.  Each is 4.85 M, and contains 1373 (or
whatever) entries.  They are, as far as I can tell, new, current, and
entirely identical.
 If they aren't -- if I have missed some subtle difference -- which

I think it's roughly:
46 - JDK 1.2.2
47 - JDK 1.3.0
48 - JDK 1.4.0

You can use BCEL (http://jakarta.apache.org/bcel/) to confirm/correct
the above (I'm only about 50% sure of the above) if you'd like.

This error comes up when you're trying to run classes compiled in a
newer JVM than the one you're running.  If you compile the classes
yourself on this machine and there's only one JVM on this machine, I'm
stumped ;)  If neither of those is true, make sure your only JVM on this
machine is the latest JVM possible.

Have you benchmarked tomcat 5.x vs. 4.1.x to come up with the above speed and memory

RE: Installing Tomcat as a Service

[Steph Richardson]

Sounds like your problem can be easily solved by reading the manpage, as the previous 
email from Paul suggests.
man chkconfig
will tell you exactly why "service service-name does not support chkconfig"

The whole point of chkconfig is to manage the installing of the service for you ( e.g. 
symlinks to init.d/yourscript from different
run levels)
You need specially formatted comments in your scripts, starting with something like "# 
chkconfig : 2345 80 20" - the manpage has an
example.

Hello all!

i have setup apache2 with mod_jk2 and tomcat4.1.27 and all works fine,
but the following log messages is written to the mod_jk log file:

as i can see this log message is written on every request, so i can
change the log level or if there is a real problem would appreciate
solving the problem.

is this a real problem? and if yes, does anybody know whats the problem?
i have tried several things with WORKER.sockt_keepalive and

That's pretty much what I guessed myself, but I when I checked the java

This is the version of Java the Installation Wizard alledged that it was using
when I isnatlled Tomcat -- in fact, it is the only version of Java on this

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.

There a lot of different tools (commercial and OSS) available, just do a
search on google.

RE: Installing Tomcat as a Service

[James Harman]

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.

I would look at the other scripts in init.d for
information on how to write one.

Re: CVS with tomcat

[SuniX]

Thank you
Can you give an example of ant source whick "reload and deploy" to a 
tomcat server? It can help me.
Thanks

With ant, you can create targets that reload your app or deploy it to a 
tomcat server.  That's what I do currently and it even integrates well 
with eclipse!
If you really want to do it automatically I heard cruise control does 
that sort of functionality, but I'm not sure about having it look for 
changes in CVS.

apache2, mod_jk2, tomcat4.1.27: "server has been restarted or reset this connection"

[Chris Joelly]

Hello all!

i have setup apache2 with mod_jk2 and tomcat4.1.27 and all works fine,
but the following log messages is written to the mod_jk log file:

19.08.2003 16:43:05 org.apache.jk.common.ChannelSocket processConnection
INFO: server has been restarted or reset this connection
19.08.2003 16:43:05 org.apache.jk.common.ChannelSocket processConnection
INFO: server has been restarted or reset this connection
19.08.2003 16:43:05 org.apache.jk.common.ChannelSocket processConnection
INFO: server has been restarted or reset this connection
19.08.2003 16:43:05 org.apache.jk.common.ChannelSocket processConnection

as i can see this log message is written on every request, so i can
change the log level or if there is a real problem would appreciate
solving the problem.

is this a real problem? and if yes, does anybody know whats the problem?
i have tried several things with WORKER.sockt_keepalive and
WORKER.socket_timeout, but things don't change...

thx,

Chris

;( ;(

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.

high memory usage ....

[Mipam]

Hi,

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?
Furthermore, all the java processes are started under user root.
Is there a way to start the java processes under another user?
Any particular version of java and/or tomcat adviced to deal with these
problems?
I guess auditing the java applications which are written is also very nice
to do and fixup some memory leaks if they're there?
Bye,

Mipam.

Connecting to MySql. Cannot load JDBC driver class 'null'

[Hugo Martínez Prado]

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  within server.xml, to setup JDBC driver manager. Which
for I had to modifify the next lines:


driverClassName
org.gjt.mm.mysql.Driver
 

for these ones:

 
driverName
org.gjt.mm.mysql.Driver
 

The steps I made here are an adition over the manual found in  Tomcat web
page. For further reference, please follow th link shown in this mail.

RE: Installing Tomcat as a Service

Thanks for the reply, I've tried creating a script in the /etc/init.d
directory and then running the chkconfig --add script-name and this hasn't
worked for me.

I'm getting an error saying that:
service service-name does not support chkconfig

I must still be doing something wrong?

The script has the same permissions showing in the ls -l list?

RE: Installing Tomcat as a Service

I already have done the hard work of intergrating apache and tomcat together
in the desired way. I now need to install the services. Going to the RPM is
a backward step for me now. Ideally i'd like to understand how the services
are installed under the linux os now.

I'll still have to research it to get the Java applications started as
services.

Re: About heap size, gc and newsize

[Norris Shelton]

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.

Exception processing JAR

[Tim Davidson]

We are using the jregex package in our application, and when tomcat starts it causes

Referencing Tomcat JNDI datasource

[Don Ross]

Hello,

I am using Tomcat 4.1.18 and have setup a JNDI datasource for database connection 
pooling.

I would like to reference this datasource from another application that is not running 
under Tomcat.

In searching the mailing list archive and other forums I found dated information that 
indicated that this was not possible that I would have to use another database 
connection pooling utility such as DbConnectionBroker from Javaexchange.com.

Is this still the case with the latest versions of Tomcat?

Has anyone used DbConnectionBroker to provide database connection pooling with Tomcat 
and in a stand alone application?

Any suggestions on other ways to use a database connection pool with Tomcat and from a 
stand alone application?

Thanks,

Don

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.

Not true.  They will be reclaimed when possible according to the

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 ;)

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.

Do you actually get up to 384 processors?  Are they all active?  Are any

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: About heap size, gc and newsize

[Shapira, Yoav]

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.  The settings below aren't likely to be optimal as they
leave a big chunk (50%) of the heap fixed and for the young generation,
yet you're not collecting the young generation any more actively than
usual.

control own servlets with jmx

[Jan von Bargen]

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

(Renamed subject/topic since the DataSource Realm part works now, just the
normal JNDI DataSource for my code gives the "name jdbc not bound" error)

Yes, driver is in /commmon/lib.  I'm quite experienced using JDBC access
from servlets, just not with JNDI.

As far as how I'm instantiating, isn't it supposed to be the same no matter
if it's defined in the Context or Globally?

Here it is anyway, same result with commented out string and other:

--
javax.naming.Context ctx = new InitialContext();  
  
// DS = (DataSource)ctx.lookup("java:comp/env/jdbc/Auth");  
DS = (DataSource)ctx.lookup( "jdbc/Auth" );  
  
Conn = DS.getConnection();
--

Both give same error, but the commented out one works when the  is
in the .  Also, all the surrounding/supporting code of this
has worked for years in production as a regular JDBC connection.

If anyone thinks they can help but this is getting too jumbled, I'll repost
with configs and skeleton code.  Let me know, I'd love for this to be a
config problem only :)

Ok, so changing the "dataSourceName" attribute in the Realm config (as you
suggest which contradicts the HOWTO) to the short name I've given my
resource makes the Realm auth work with the globally defined datasource.
Yay!

However, when trying to connect to the datasource (moved the "jdbc/Auth"
resource from  tag to  tag), my
servlet application still gives the same "Name jdbc is not bound in this
Context" error.

You mention not having to put a  in the context specific
web.xml file, and I assume your suggestion to put  tag in the
Context (in my case putting it in the  tag so it works, or
should, for all autodeployed contexts) is what you mean removes the need for
the those aforementioned entries.  However, it doesn't appear to work (as it
_does_ work when I move the whole / tags into the
 tag.  Don't want to do this as I will have multiple virtual
hosts using the same resource...)

Doubt it's of importance, but adding the  you suggest is not
necessary produces the elusive "Cannot load JDBC driver class 'null'" error,
which I believe is unrelated.

Any more ideas why my app would not see the global resource as defined below
as a global resource and then resource-linked in the default context?

RE: Problem with context.xml and deploying

[Allan Schweitz]

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?

Tomcat holding problem - CLOSE_WAIT

[Venkata Srinivasa Rao, Yerra]

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.

Manager Component configuration

[Daniel Haynes]

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

Re: maxProcessors problem

[achana]

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.
Arthur ;-)

Installing Tomcat as a Service

[Stuart Stephen]

Hi all,

How might I go about installing Tomcat as a service in RedHat 9.0. I've
never installed a service under linux manually before and I'm not sure what
to do. I can't find the appropriate documentation in the manuals for either
Tomcat or RedHat. I must be looking in the wrong places :O(

UNRELATED: Also, If I wanted to install a java program as a service, how
might I do this? Is this a similar process?

Regards,
Stuart

RE: directory outside context root

[Stuart Stephen]

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. If these files should have restricted
access then that adds more to the equation.

Well I did find a way to do that by declaring another context just for
that with docBase='c:\www\files' for example. Thing is, all this is not
really working under the Tomcat bundled in JBoss.

One option of solving this is having a servlet (Struts Action for
example) which will serve the files.

The other way is using the 'alias' directive under Apache directing to
wherever I'd like in the file system. For that I need to put Apache in
front of JBoss/Tomcat.

Which is better?

Thanks,
Erez

If on UNIX or Linux, you could use symbolic links, but this is not
recommended for security and portability reasons.

So, in general, the answer is "no".

Re: That ever-popular 'wrong version:46, expected 45' message

[Jon Wingfield]

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...

What does java -version give?

Paul R Gazis wrote:
I'm running the J2SE 1.4.1_04 SDK and Tomcat 4.1.27 under Windows 2000.
The Tomcat installation runs fine, but try as I might, I cannot compile

Any suggestions?  Surely this is a common problem, for which the solution
is well known.  I would welcome any help.  Thanks!

R: How to send back data without to wait for the complete page.

[Unternaehrer Stefano]

Thank you Mike.
Yes I could write a "please wait" and than display all the result.
But I would prefer the replay "piece by piece", when possible.
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. As you can see, first comes quickly
then others appears later. That's GREAT! I want do that!! :-)

Best regards,
Stefano

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).  But, be careful if you're displaying
these rows in a table.  Netscape (I'm not sure if this holds true for newer
Gecko powered versions) for example won't render a table until it's received
the whole thing.

Hope that helps,
Mike

Hello all.
Hope the subject explains what I mean.
I even don't know how to call that, so cannot
search it in archives, and don't know if this
behaviour can be setted for a specific jsp page
or at tomcat configuration level.

I have a page wich requires some time to be
executed, you can imagine to receive a table
with different rows, where every row require
some time to be prepared. I would like that
the used doesn't need to wait for the last
row to be ready before to see something,
but instead that it will see the first rows
as soon as possible, than others following
when ready. Is this possible with tomcat?
I'm using version 3.2.1 but can upgrade
when required.

Thank you and best regards,
Stefano
