my jsp's having a import([EMAIL PROTECTED] import =Test%) of one java 
class(Test.java) which is not included in any package( I mean it is not having 
a package name. i.e dierectly placed under the root directory).  Here I am

Venkat,

Here's one method:

1) Create an HTML Page, in Apache's html document root called something like 
error500.html. Note that this assumes that Apache is serving HTML pages and Tomcat is 
serving jsp pages.

2) Add the following line to your httpd.conf file, somewhere in the Main Server 
Configuration

ErrorDocument 500 /error500.html

3) Shutdown Tomcat and restart Apache.

4) Try browsing to a jsp page and you should see your error500.html page.

Steve

I am curious about the same thing.  My app isn't fully up and operational
yet so I do not know for sure if I suffer from the same problem, but I have
noticed that while doing some testing new threads are getting started, and
it usually takes a restart to get rid of them.

I've seen this question posted a few times, but haven't noticed any
'resolution' or possible solutions.  Can anyone recommend things to check
for, settings to make, or perhaps any documentation on the issue?

Is it possible that this could be a JSDK 1.4 issue?  It's the only common
link I've noticed between my set up and other posters with this problem.

Thanks :)

Subject: HELP, PLEASE! Tomcat creates too many threads!



Hello all,

Im running Apache and Tomcat in  a Linux machine, after a couple days
and several accesses to my applications, Tomcat creates several
threads/processes that stay sleeping, as you can see at the end of this
e-mail.
Im using Tomcat 4.0.4, Apache 1.3.26 with mod_webapp, and Java 1.4.0_01.
If I don't restart my tomcat, it will exceed the maximum number of
processes the user can execute and it will block, turning my applications
offline.
Is there any solution to this problem? How is it possible to avoid the
creation of so many processes?

I really appreciate any help you can give me.

These lines are only a few ones I get when I run the ps -elf command:

RE: JK2/tomcat 4.1.18 - broken pipe problem

[Venkat Reddy Valluri]

I thought this could never be a problem(user htiing stop button), as I alreday mailed, 
I got it solved by relpacing sun jvm with ibm jvm, But I got it on redhat linux, but 
you are on solaris right, So what I am thinking is to  think this problem in different 
dimension, This is just my suggestion

Thx, Bill!

But how do I get rid of them in my catalina.out log file ?! Should I set
file logging in the worker2.properties ?! jk2.properties ?! Something
:-)

/Jesper Birch

The most common reason for this is that the user has hit the stop
button
in the browser before the page has been fully loaded.  The AJP13
protocol
(currently) doesn't support out-of-band messages to notify Tomcat of
this
fact, so mod_jk(2) simply drops the connection to Tomcat instead.

 It does not seems like the users of my site has any problems when
using
 it. So I am not sure when exactly this is happening.

 Can somebody explain for me the condition for when this should happen
-
 so I can look into this error, or maybe somebody has an idea to what
the
 problem can be ?!

 I have built JK2 from the 4.1.18 connectors package..

 Thanks

RE: JK2/tomcat 4.1.18 - broken pipe problem

[Venkat Reddy Valluri]

Even I too got the same problem with configuraion of apache 2.0.40, tomcat 4.0.4 and  
j2sdk1.4.1(sun jvm) on redhat 7.3
 but when I replaced sun jvm with ibm jvm, surprisingly I didn't get this problem, 
I am not sure here but what I thought is sun jvm   can't support green threads on 
redhat linux but supports only native threads where as ibm jvm can support green 
threads on linux machines

I beleive we are dealing with a different problem. My app has been
running on Tomcat 4.0.6 for weeks until I had the problem recently.
There was no crash.

What happened was, it seems, a user REALLY fat-fingered the enter key or
some smart person sent the same request to the server 180 times within
one minute. I traced back through my access logs for Apache and caught
the massive number if requests for one URL at the same time I had the
problem.

All of these requests overwhelmed the number of AJP13 processors I had
configured (well, they are still at the default setting) and also caused
a massive opening of database connections.

Anyway, as to your problem: You may not have enough memory setup for
your JVM. Do you send amx -Xm and -Xs parameters to Tomcat using
JAVA_OPTS? You may be getting more load then Tomcat can handle due to a
RAM constraint.

 I had suspected that in the problem earlier in the day (the part of the

 what did not make sense was the connection pool woth the database also
 going up.
 
 If I understand the stuff below, after 85 concurrent connections (max
 connections + accept count) I would start getting the Out of
 Processors error. However, I cannot see how this would cause the
 DATABASE connection pool to grow as large as it did (we usually handle
 50k connections a business day with 5 pooled connections; during the
 earlier problem, the database connections went to *30*, our maximum).
 
 Additionally, why would we contine to get the following error:

Subject:Tomcat and Apache | Performance
Hi All,
I am using tomcat 3.3.1 and apache 1.3.27 with mod_jk (ajp12
protocol). We are running it in Solaris 2.8 ( 4 CPU 4GB RAM ). At times
when the system is under heavy load, apache simply stops processessing
requests. And the hits/sec goes down. The system idle state is around
99%. At times , we get MaxClients reached error in error_logs. But
this happens rarely. 
After 10 or 15 minutes, apache is able to serve requests.
Has anyone expericed this kind of problem. Any pointers would be greatly
appreciated.

Rajesh.B

Running tomcat 4.0.4 with j2sdk1.4.1 on redhat 7.3 dual processror gives out of memory error in syslog messages

[Venkat Reddy Valluri]

Hi,
  I am sorry, Iam posting  this question again, as I didn't get any response for this 
question 
  I am running tomcat 4.0.4 on redhat 7.3 dual processor machine(2-4-18-3SMP) with 
j2sdk1.4.1 for my web application,
 The problem is after  couple of hours(6 or 7 hours after 7 or more  users hit the 
system), tomcat crashes and I ened up finding kernel out of memory killing java 
process in syslog messages(/var/log/messages)
  It is not the problem with java heap size I think
  The same web application is running successfully on tomcat 4.0.4 on redat 7.3 
(2-4-18-3) single cpu machine with j2sdk1.4.0

  Here I didn't understand if multi processor redhat 7.3 matters with j2sdk1.4.1

Any help greatly apprecited

Hi,
According to you, every thing is fine(i.e ajp13 is working fine and listeneing on 
8009), can you just verify your mod_jk.conf and check if you are using hostname as 
localhost and verify in server.xml if you use same name for host and engine 
(localhost)
   if you use same name then how do you configure your context and appbase?

Hi Raj (and thank you for your help yesterday)...
I tried to connect using telenet to localhost 8009 and... there wasn't connection
refused, but the connection wasn't accepted (showed the Escape character ... ),
finally I killed the telnet process because no response was given.
I think that the ajp13 connector (tomcat) is not running in the rigth way,
because, seems that apache finds the worker (the worker name is ok):

   [Tue Oct 08 02:49:21 2002]  [jk_worker.c (187)]:
  wc_create_worker, done
   [Tue Oct 08 02:49:21 2002]  [jk_worker.c (238)]:

  build_worker_map, done
   [Tue Oct 08 02:49:21 2002]  [jk_worker.c (111)]: wc_open,
  done 1

My workers.properties is:
ps=/

worker.list=local_pt1

worker.local_pt1.port=8009
worker.local_pt1.host=localhost
worker.local_pt1.type=ajp13

worker.local_pt1.lbfactor=1

My server.xml:
!-- Define an AJP 1.3 Connector on port 8009 --
Connector className=org.apache.ajp.tomcat4.Ajp13Connector
   port=8009 minProcessors=5 maxProcessors=75
   acceptCount=10 debug=0/

And, in catalina_log, seems that the connector starts all threads:

2002-10-08 02:35:06 Ajp13Connector[8009] Opening server socket on all host IP
addresses
2002-10-08 02:35:06 Ajp13Connector[8009] Starting background thread

Any ideas?

 Hi Marc,

 Though I am not expert in the JK Connectors, But it is very clear that
 mod_jk part at apache is not able to connect to the tomcat process.

 There may be three reason for this:-

 1. Your JK connector on tomcat is not listening on port 8009.
 2. The host name of the worker in worker.properties and tomcat does not
 match.
 3. Tomct is not running at all.

 Pleas double check your JK connector configuration in server.xml. Check
 the default host name in tomcat and worker.properties for the local_pt1
 match.

 Try telneting to the host and port you have configured in worker.properties.

You can use  OracleConnectionCacheImpl to implement connection pooling
you have to set the attributes for this  by getting them from web.xml

Maybe you can use the connection pooling provided by tomcat. See the

Subject:RE: Apache2 and Tomcat4 on different boxes
Hi Venkat,

Here it goes.

Machine  A (Apache), Machine B (tomcat)
—-

httpd.conf changes...
—-
Below # LoadModule foo_module modules/mod_foo.so

Add following lines
#
# Load mod_jk
#
 LoadModule jk_module libexec/mod_jk.so
#
# Configure mod_jk
#
JkWorkersFile conf/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel debug

Below DocumentRoot /usr/local/apache/htdocs

Add following lines...

JkMount /examples ajp13
JkMount /examples/* ajp13

(if you want to configure a application examples running under webapps
on tomcat, just specify  /examples, you need not sepcify the full path
of the application)

Then create workers.properties under $Apache_Home$/conf/  like this 

# In Unix, we use forward slashes:
ps=/

# list the workers by name
worker.list=ajp13

#
worker.ajp13.port=8009(ajp13 port from server.xml on tomcat machine)
worker.ajp13.host=hostname(Machine B)
worker.ajp13.type=ajp13

(no need to define tomcat_home and java_home parameters here, you define
them on catalina.sh on tomcat machine)

this is all you need to do on apache machine...

server.xml changes on  Machine B(tomcat machine)
—--

Set the required environment variables JAVA_HOME AND CATALINA_HOME in
$TOMCAT_HOME$/bin/catalina.sh

Commen out the Standalone HTTP port(port 8080) Connector. 

!--
Connector
className=org.apache.catalina.connector.http.HttpConnector
   port=8080 minProcessors=5 maxProcessors=75
   enableLookups=true redirectPort=8443
   acceptCount=10 debug=0 connectionTimeout=6/
--


Also Comment out the WARP connector 

  Service name=Tomcat-Apache
!--
Connector
className=org.apache.catalina.connector.warp.WarpConnector
 port=8008 minProcessors=5 maxProcessors=75
 enableLookups=true appBase=webapps
 acceptCount=10 debug=0/
--


Change the both the Engine Tag and Host tag defaultHost to tomcat
hostName(ex: tomcat.apache.com) 
(This should match with your workers.properties host name.)

Engine name=Standalone defaultHost=tomcat.apache.com debug=0
  Host name=tomcat.apache.com debug=0 appBase=webapps
unpackWARs=true
  /Host
/Engine

start tomcat and apache, you should be able to access examples from
apache machine

I have pretty much followed the http://www.ubeans.com/tomcat/
documentation..many many thanks to Pascal Forget.


Let me know, how it goes...

Hi Raj,
  you did  Excellent job,  can you pl explain me how you did, can
you answer for following questions
   1) I installed Apache 2.0.40 on Machine 'A' and built
  mod_jk.so module (./configure
  --with-apxs=/usr/local/apache2/bin/apxs
  --with-java-home=/usr/java/j2sdk1.4.0_01), It was suceesfully
  done and got mod_jk.so
 
 2)  I installed Tomcat 4.0.4 on machine 'B' and copied
  mod_jk.so from machine 'A'(Apache machine) to Machine 'B'
  (Tomcat machine),
 
  and modified server.xml as per the documenatation  
here is server.xml ---
Server port=8005 shutdown=SHUTDOWN debug=0

Host name=localhost debug=0 appBase=webapps unpackWARs=true
Listener className=org.apache.ajp.tomcat4.config.ApacheConfig
append=true forwardAll=false modJk=/opt/catalina/modules/mod_jk.so
/






  here Upon start up of tomact I got mod_jk.conf, I copied
  it from machine B to Machine A(Apache Machine)   and included
  it in httpd.conf
 
  Here I did not understand Following things
  1) in mod_jk.conf  (on Machine 'A' Apache)
Alias /manager /opt/catalina/webapps/manager --
  here what I need to put,  because the path mentioned  is
  there on machine 'B'
 
   2)in workesr.properties (on machine 'A' Apache)
 worker.ajp13.host= machine 'B' I am sure This is ok
 workers.tomcat_home=/opt/catalina
 workers.java_home=/opt/java/j2sdk1.4.0_01,   here what
  I need to set up for these (because catalina_home and
  java_home are there in Machine 'B')
 
  here I didn't get any error in mod_jk.log (on machine 'A') 


Thks in advance
Venkat


at on a different
machine. The problem was on tomcat configuration,I had defaultHost
defined as localhost on Engine tag and actual hostName on Host tag,
Once I have changed the defaultHost on Engine tag to actual DNS name,
every thing worked fine.

RE: Apache/Tomcat Configuration Question

[Venkat Reddy Valluri]

Did you change mod_jk.conf to point to document root where you are supposed to give 
apache doc root
  sample mod_jk.conf--

IfModule !mod_jk.c
  LoadModule jk_module /usr/local/apache2/modules/mod_jk.so
/IfModule

JkWorkersFile /tmp/workers.properties
JkLogFile /usr/local/apache2/logs/mod_jk.log

JkLogLevel debug


VirtualHost xxx.xx.xx.xx
ServerName www.xxx.com:80

 aurora.quinnfable.com:/manager 
DocumentRoot-- here you got to give your apache document root 
---

Subject:Apache/Tomcat Configuration Question
All,

I have Apache and Tomcat integrated together using
mod_jk.  The problem is now when I hit my webserver,
it always defaults to the root context of tomcat.  No
matter what I set in my Apache httpd.conf file it gets
ignored.  I have tried to setup a virtual server in my
httpd.conf file to point to the docroot I want to
serve up as the default, but it is ignored. 
Originally I had my Apache working with PHP, but since
I installed Tomcat, I have been unable to figure out
how to serve up both.

Thanks,


John Green

RE: unusual problem after installing mod_jk.so ???

[Venkat Reddy Valluri]

I too got the same problem, here I what I understood is , when you try to execute 
/examples/jsp/images/ you could see iamges, but you can't execute jsp's this means 
apache itself  is executing /examples/jsp/images/ but not tomcat,  because images can 
be viewed by apacahe but where as jsp's can't be executed by apache right,
 So here my conclusion is might be either you didn't configure mod_jk.so properly 
or workers.properties  and mod_jk.conf  properly
  better try to reconfigure mod_jk.so

If exmaples are in /path/to/tomcat/examples and your Apache root is
/some/other/path/to/htdocs then yes, it sounds like you have mod_jk.so
installed.

From what you have said, it sounds like your JkMount directives are not
correct.

 Hi All.
 I believe I might have installed mod_jk.so 
 Tomcat works fine : http://MyServer:8080/examples;.
 All executables in jsp/ and servlets/ work fine.
 From IE I entered http://MyServer/examples; ... 
 (1) list for images/ ; jsp/ and servlets/ comes up ;
 (2) all 3 images shown when clicked - fine ;
 (3) clicked and gone into jsp/ all the examples show up.
 (3.1) clicking on number guess, rate, snoop etc throws this 
 error : page
 cannot be found
 (3.2) clikcing on ErrorPage -- Select car / submit -- page cannot be
 found
 (4) Likewise servlets/ , can go in but cannot execute the examples.
 (5) All source codes can be displayed when clicked on.
 
 This is excruciating : 
 * Have I installed mod_jk.so sucessfully or not ???
 * Have I got Apache talking with Tomcat ???
 * How come most of the executables cannot be run ???
 
 Close yet so far

 [EMAIL PROTECTED] 09/19/02 03:58AM 
Sorry I look at your config files, but I see nothing bad (as you I think
;-) )

In your mod_jk logs, we can see that the ajp13 worker is not found first
then it's running and found by Apache. And then, it's closed during
request
processing.
That's a strange beaviours.

You run this configuration :
Apache/2.0.39 (Unix)
mod_ssl/2.0.39
OpenSSL/0.9.6g
mod_jk/1.2.0

What have you compile by your self?
If I were you, I will recompile Apache 2.0.39 (You can change to 2.0.40)
without mod_ssl, mod_jk 1.2.0 and Tomcat 4.0.4 on your machine, because
it'is so strange...
Try to restart your test in a clean environement. Save your config
files,
they seem to me not bad.
Try to do a working configuration without mod_ssl.

That's poor help... Sorry. But 

problem with connecting Apache2.0.40 and Tomcat4.0.4 installed on diffrent machines with mod_jk

--with-apxs=/usr/local/apache2/bin/apxs --with-java-home=/usr/java/j2sdk1.4.0_01), It 
was suceesfully done and got mod_jk.so

   2)  I installed Tomcat 4.0.4 on machine 'B' and copied mod_jk.so from machine 
'A'(Apache machine) to Machine 'B' (Tomcat machine),

and modified server.xml as per the documenatation
here Upon start up of tomact I got mod_jk.conf, I copied it from machine B to 
Machine A(Apache Machine)   and included it in httpd.conf

Here I did not understand Following things
1) in mod_jk.conf  (on Machine 'A' Apache)
  Alias /manager /opt/catalina/webapps/manager --  here what I need to put,  
because the path mentioned  is there on machine 'B'

 2)in workesr.properties (on machine 'A' Apache)
   worker.ajp13.host= machine 'B' I am sure This is ok
   workers.tomcat_home=/opt/catalina
   workers.java_home=/opt/java/j2sdk1.4.0_01,   here what I need to set up for 
these (because catalina_home and java_home are there in Machine 'B')

here I didn't get any error in mod_jk.log (on machine 'A')

Any help greatly appreciated

The lines like tomcat_home etc. in workers.properties are optional.
(thanks Milt!)  You only need the worker definitions (like port number,

I'm not sure about the Alias /manager question, that is a good question.

You don't need mod_jk.so on the Tomcat box, its an Apache module.

RE: problem with connecting Apache2.0.40 and Tomcat4.0.4 installed on diffrent machines with mod_jk

[Venkat Reddy Valluri]

Even though I didn't copy, Atleast Apche should have connected to tomcat and I should 
have executed jsp pages existed on tomcat box, here apache is serving some static 
files which are existing on apache boxe, but when I tried to execute 
http://www.xxx.com/examples/(in mod_jk.conf  jkmount  /examples/* ajp13) it is 
supposed to connect to tomcat box and execute jsp's, but it is not recognising them, 
because it is not even connected to tomcat

If you want to put Apache and Tomcat on separate boxes, and still run the
Tomcat examples, you will have to copy the static (.html) files from the
tomcat box to the apache box so that apache can serve them.

The lines like tomcat_home etc. in workers.properties are optional.
(thanks Milt!)  You only need the worker definitions (like port number,
etc).

I'm not sure about the Alias /manager question, that is a good question.

You don't need mod_jk.so on the Tomcat box, its an Apache module.

 Subject: problem with connecting Apache2.0.40 and Tomcat4.0.4
 installed
 on diffrent machines with mod_jk


 Hi,
I installed Apache 2.0.40 and Tomcat 4.0.4 on different
 Linux(RedHat) servers and tried to make apache connect to
 tomcat with mod_jk module,

For this I did the following things
1) I installed Apache 2.0.40 on Machine 'A' and built
 mod_jk.so module (./configure
 --with-apxs=/usr/local/apache2/bin/apxs
 --with-java-home=/usr/java/j2sdk1.4.0_01), It was suceesfully
 done and got mod_jk.so

2)  I installed Tomcat 4.0.4 on machine 'B' and copied
 mod_jk.so from machine 'A'(Apache machine) to Machine 'B'
 (Tomcat machine),

 and modified server.xml as per the documenatation
 here Upon start up of tomact I got mod_jk.conf, I copied
 it from machine B to Machine A(Apache Machine)   and included
 it in httpd.conf

 Here I did not understand Following things
 1) in mod_jk.conf  (on Machine 'A' Apache)
   Alias /manager /opt/catalina/webapps/manager --
 here what I need to put,  because the path mentioned  is
 there on machine 'B'

  2)in workesr.properties (on machine 'A' Apache)
worker.ajp13.host= machine 'B' I am sure This is ok
workers.tomcat_home=/opt/catalina
workers.java_home=/opt/java/j2sdk1.4.0_01,   here what
 I need to set up for these (because catalina_home and
 java_home are there in Machine 'B')

 here I didn't get any error in mod_jk.log (on machine 'A')

 Any help greatly appreciated
 ThksRgds
 Venkat

I wish I could help more, but I haven't had the need to do separate-machine
Apache + Tomcat, so all I know is what's in the documentation and what's
been posted to the list.  I haven't tried it at all.

As far as I know, you set things up according to this URL:
http://www.ubeans.com/tomcat and then you just change the host parameter in
workers.properties to be the fully-qualified domain name of the Tomcat host
(or perhaps the IP address would be better, but then I'm not sure that
Tomcat would get the host header right).

Maybe this weekend I will give setting these up on different boxes a shot,
if I have time.  It would be an interesting experiment.

John

 I *just* completed a successful configuration of Apache
 2.0.40 and Tomcat
 4.0.4 using the mod_jk.so connector (provided by John Turner,
 thanks John)
 on RedHat Linux 7.3 where Apache and Tomcat are running on separate
 machines.

 If Apache is not connecting to tomcat, then you should look
 on the Apache
 box for the cause (assuming that the Tomcat box is running! g).

 In your httpd.conf file, there should be two directives, JkLogFile and
 JkLogLevel.  Set the JkLogLevel value to debug and restart
 Apache.  Then
 when you make a request, you should be able to see what is
 happening via the
 log file.

 Note: If you followed John's instructions for configuring the
 system, you
 will have a problem because those instructions depend on the
 Tomcat listener
 (ApacheConfig) to generate the mod_jk.conf file.  This won't
 work if tomcat
 and apache are on separate boxes, so you'll have to do that
 part manually
 (or copy the generated file from the tomcat box to the apache box).

 If your httpd.conf file contains this directive:

   include /usr/local/tomcat/conf/auto/mod_jk.conf

 then you will have problems, because tomcat is not on the apache box.

Venkat,

Yes, I will give you more details, however, I've got higher priority things
to do at this moment, so it will take me a few hours before I can document
the details.
