Re: binary streaming / content-type problem with mod_jk ?

[Jérôme Chauvin]

Thanks for your answer Henri :)
I agree with you, finally I don't think the problem comes from mod_jk
It may be Apache (using mod_jk and Tomcat) like described by Stuart 
Hynd in his post on this page : http://www.junlu.com/msg/107218.html


Or, perhaps, QuickTime 6 which is more "weaker" than QT7 which doesn't 
care about the thing which makes the problem (and I would like to know 
where this thing comes from).


But the incredible thing is that, using this : 
http://localhost:8080/my_test/BinaryStreamingit works perfectly on 
QT6  (without the 8080 port, the latence problem appears -> QT6 or the 
servlet or Apache, is waiting for the video file entirely created 
before starting to play it)...



Any other suggestions or opinions about this mystery ? :)

Hi all !

I've developed a servlet ("BinaryStreaming" based on

played by Quicktime.
I use Apache and Tomcat so I've installed mod_jk

the viewing instead of starting to play the movie as soon as there is

-> like it does with QT7 and QT6 with :8080  OR  when I use QT7

Problem with mod_jk 1.2.8 (and 1.2.10) and Tomcat 4.0.4

[Laurent LE PRIEUR]

Hello,
I have a problem of ping pong between the connector mod_jk and tomcat 4.0.4 
which entraine a significant load network.

Sequence 1234 APACHE MOD_JK to TOMCAT
Response AB (TOMCAT to APACHE MOD_JK)
http://jakarta.apache.org/tomcat/connectors-doc-archive/jk2/common/AJPv13.html
I manage to reproduce the problem in the following way:  I have an 
application which allows me to send a file (I a file of 5 Mo takes for 
example) and I the transfer stops while close my navigator at this time 
there sequence AB/1234 never stops (infinite).  Useless to say to you that 
if 20 or 30 users make celà, one arrives at a load very significant network.

tcpdump on localhost showed me that there is continues traffic between
both the httpd/mod_jk and the tomcat server (ajpv13).  The traffic is
always the same.  A request from the container (AB -> in ajpv13
this means "Get Body Chunk") and a reply from the server (1234|00|00 ->
this is an 'empty packet' telling there is nothing more to be sent).
I found only one mail in this direction in mailing list archive.  And no 
response to this problem.  Can you help me?

Uppercase index.jsp problem with mod_jk 1.2.8 ?

[Andre Schild]

Hello,

we actually use mod_jk 1.2.5 with apache 2.0.52 under win32.
We tried to upgrade to mod_jk 1.2.8, but we get a problem with it.

When specifying a URL like http://www.client.com then
the request is forwarded to tomcat, but tomcat is asked for
the file Index.jsp, where on disk only a index.jsp exists.

So it looks like mod_jk always looks for a uppercase index file.

When we specify http://www.client.com/index.jsp then everything
works fine...

In the apache config we have this:

DirectoryIndex index.jsp Index.jsp index.html Index.html default.html
Default.html

In the tomcat config we have this:


index.html
index.htm
index.jsp




If I change the DirectoryIndex to be:

DirectoryIndex index.jsp index.html default.html

Then everything works fine. (But of course the Uppercase index files won't
be served any more)

Re: Problem with mod_jk 1.2 - 500 Internal Server Error

Well, I managed to get it.  And I feel unbelievably stupid (as is the

worker.list=default
rather than
workers.list=default

Looking at the mod_jk.log shows:

Windows XP IIS 5.1 HTTP Post Problem with mod_jk

[Eric Jacobson]

Has anyone else run into a problem where mod_jk does not work right with IIS
5.1 on Windows XP Professional? I am trying to connect Tomcat to the IIS
that is part of XP Pro and it will work for HTTP GET requests but it does
not work for HTTP POST requests.

I can get this same configuration to work with multiple other flavors of
Windows (Win2k Pro, Win2k Server, Win2003 Server), but I have had the same
problem with XP on half a dozen machines.

Any help would be appreciated.

You're trying to use mod_jk2 with the mod_jk1 syntax.

You must use the JkUriSet or uri mapping, take a look at jk2
documentation.

New users Problem with mod_jk

Dear Lists,

I'm interesting to integrating Apache Server and Tomcat so my

But I have some difficulties, here goes the detail.
My httpd server is apache-2.0.47 (installed from FreeBSD-4.9Stable Port)

RE: problem with mod_jk 1.2: error in action code

[Ralph Einfeldt]

I don't see any reason why an object in the context
should have any thing to do with the stacktrace.

What makes you think that they are related ?

What makes you think that the pool is lost ?
(context.getAttribute("") == null ?)

Or do you just don't get connections from the pool ?

Or are the connections you get from your pool just invalid ?

Or what else happens ?

RE: problem with mod_jk 1.2: error in action code

[Mike Curwen]

I don't deny the stacktraces the original poster included are from a
connector.

But... the original problem relates to loosing a 'database connection
pool', which should have nothing at all to do with the jk connector.  I
don't think it's very clear yet, what is *actually* going on.  
 
If you are correct, and the database thing is a red herring, then fine,
he can ignore that annoying (and common) jk message. I get them all the
time, I've asked a couple times for help in getting them shut off... oh
well. That's jk for you.

If, otoh, he's got a database problem, and while trying to diagnose the
trouble, noticed those common jk errors, and related the two (his
database trouble to the jk error messages), then his trouble is *not*
with jk, but with his connection pool. 
 
He did, after all, say "I think...".  I was attempting to eliminate a
very common cause of 'lost connections' to a mysql database.

And.. who first mentioned the Coyote HTTP connector ??  I see in the
original poster's server.xml:
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"
 
that looks the configuration for an AJP 1.3 connection to Apache.

AW: problem with mod_jk 1.2: error in action code

[Michael Görlich \(CSC\)]

Hi,

I programmed a connection pool by myself as an object, that I put into a
global variable by  context.setAttribute(myConnectionPool).

The lost of the pool is a subsequent error, that occures as a reason of the
error in the action code of the coyote connector.

In the mysql logs there is nothing to see about errors.

By the way, my workers.properties are:

worker.list=worker1
worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor=50
worker.worker1.cachesize=100
#worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
#worker.worker1.socket_timeout=300

Great problem!!!

I don't think that this message has anything to with the lost
connection pool.

(Do you really mean 'connection pool' and not just 'connection' ?)

If you lose your connection, it may be caused by the databaseserver
that cancels idle connections after a while.
Look for validationQuery in:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-resources-howto.html

The message in the mod_jk.log is typically indication that a browser
was closed while tomcat was sending an answer.

I'm not shure if the message in catalina.out is related to that.

I wish I could kill the 'autoReconnect' feature. You shouldn't be using
it if you're using a connection pool :)

Use the correct properties on your connection pool and you should be
good to go.

For example, setting 'timeBetweenEvictionRunsMillis' (set to some
sensible number of milliseconds, I would suggest something around 5
minutes) and 'minEvictableIdleTimeMillis' (set to the number of
milliseconds you have 'wait_timeout' set to on the server minus some %)
 should catch MySQL closing idle connections.

Setting 'validationQuery' (set to 'SELECT 1') and 'testOnBorrow' or
'testOnReturn' should catch MySQL server restarts or general network
flakiness.

In any case, you should also see the new example in the troubleshooting
section of the Connector/J docs that shows how your code can also detect
whether a SQLException was caused by a lost connection, or some other
error (section 4.4 under the following link):

Re: problem with mod_jk 1.2: error in action code

[Christopher Schultz]

All,

when you specify the connection to mysql, are you including the
'autoreconnect=true' parameter? If not, the connections will be closed
by mysql after (I think) 8 hrs.
I'm not sure why everyne's caught up in database connection code. This 
is a Coyote connector exception -- which is the HTTP/1.1 protocol 
connector. It allows you to connect directly to Tomcat using a browser, 
instead of going through Apache.

Usually the "Broken Pipe" means the the client hung up before listening 
for all the data. That could mean pressing the STOP button on the 
browser, following another link before the page fully loads, or pressing 
the back button.

I wouldn't worry too much about it, unless your users are somehow being 
affected.

Subject: problem with mod_jk 1.2: error in action code

Hello,

I've got problems with a tomcat web application, that 
establishes a connection pool to a database (mysql). This 
connection pool is lost after an unspecified period of time 
the system wasn't used (f.e. 8 houres).

I think the problem is due to the mod_jk connector between 
apache and tomcat.

The web application is accessible over apache 1.3.27, that 
connects to tomcat 4.1.27 via jk connector mod_jk 1.2.25.

The exception I got in catalina.out is:

Re: problem with mod_jk 1.2: error in action code

[Adam Buglass]

Well I run in exactly the same environment except it's a RedHat 6.2
(-ish) box

My server.xml is setup like so:




The connector is setup like so:
# BEGIN workers.properties
worker.list=ajp13
worker.ajp13.port=8009
# change this line to match apache ServerName and Host name in
server.xml
worker.ajp13.host=www.whatever.com
worker.ajp13.type=ajp13
# END workers.properties


HTH.

I can't see anything in your setup which instantly looks wrong but there
appear to be some parameters which are unnessecary, although I'm not
sure. Could it be anything to do with your timeout set to 0?

Apart from that it looks like it could be something on the SQL side
that's causing the problem.

IMHO, have a glance at the sql server logs.

problem with mod_jk 1.2: error in action code

[Michael Görlich \(CSC\)]

Hello,

I've got problems with a tomcat web application, that establishes a
connection pool to a database (mysql).
This connection pool is lost after an unspecified period of time the system
wasn't used (f.e. 8 houres).

I think the problem is due to the mod_jk connector between apache and
tomcat.

The web application is accessible over apache 1.3.27, that connects to
tomcat 4.1.27 via jk connector mod_jk 1.2.25.

The exception I got in catalina.out is:

10.03.2004 15:59:58 org.apache.jk.server.JkCoyoteHandler action

Problem with mod_jk spawning processes

[KING,SETH (HP-Boise,ex1)]

Hi all,

I am currently experiencing an issue with Apache 2.0/Tomcat 4.0.16. I am
using mod_jk to connect the two servers. The AJP13 processes are continually
being created until it reaches the MaxProcesses limit (set at 75) and then
the server becomes unresponsive. I restart the tomcat server and then after
ten or fifteen minutes the connector processes are back up to the maximum.
These servers have been working for over a year without this problem until
last Tuesday. Nothing has changed on the servers since October 2003. Does
anyone have any idea as to what is causing the AJP processes to spawn out of
control. I would appreciate any advise given.

Thanks in advance.

Re: Problem with mod_jk on RedHat 9

[Mario A. Imperato]

It's me again :-)
Well, I kept digging into it and here is what it came out.

The connector package I have been using is the one in
dist/jakarta/tomcat-4/v4.1.29/src
the same folder of the application server. (for the App server I actually
took the binaries)
As I already said I followed pretty much the howtos but with no avail. (I
tried also
the LD_ASSUME_KERNEL... just in case).

I then went to the archive.apache.org and downloaded the
jakarta-tomcat-connectors-jk-1.2-src-current... that appears to be the
1.2.5 version of the connector. I unpacked, buildconf-ed it, make, make
install.
Now I can happily click on the examples without problems (well, I may need
some more extensive testing).

To be sure I did everything up again and, apparently, there is some problem
with the 4.1.29. Don't know what but I would really appreciate if someone
could confirm on this or in case explain the source of the problem.. if
possible.
Thank you for the assistance
Mario

Hi, you out there,
I'm looking for help in setting an Apache/Tomcat configuration.
Apache: 2.0.48
Tomcat (server and connector): 4.1.29

I've been trying to follow a number of how tos, using the REDHAT
installed version of apache, building up my own version. Everything seems to
be OK:
I'm able to see tomcat through Apache but this is only for a couple of
JSPs (just testing with the examples). In fact after a few clicks everything
seems to be freezing
and if I put 'debug' on the mod_jk.so i can notice an endless list of
messages
like: jk_ajp_common.c (774): sending to ajp #.

When is that way I stop the browser and retry after a few seconds. SOmetimes
it does
other times with no avail.
Is there anybody who can shed some light on this? I'd really, really

RE: Problem with mod_jk and CoyoteConnector

[J.P. Wadkin C9951627]

Latest versions of everything: Apache 2.0.47, Tomcat 4.1.27, jk 1.2.4.
Apache and mod_jk both built from source. Apache 2 is configured to use
the worker mpm - which might well be the problem looking at the change
log for mod_jk. I'll try the pre-form mpm and if that fails I'll just
use Apache 1.3 with AJP13 connector.

Apache 2.0.47 - mod_jk2 will compile as a DSO but Apache won't start due
to a symbol error. I _thought_ I'd got everything working fine with
mod_jk, then I ran into the response problem.

I didn't mean mod_jk2.

I meant CoyoteConnector in server.xml.

In server.xml, you have a connector listening on some port (like 8009) 
for communications from Apache.  This connector has a class parameter. 
In your case, the class is "org.apache.ajp.tomcat4.Ajp13Connector".

Make it "org.apache.coyote.tomcat4.CoyoteConnector" instead and you will

be able to use MBeans.

CoyoteConnector can handle AJP13 from either mod_jk or mod_jk2, as well 
as HTTP and HTTPS.

There are actually two Apache connectors in server.xml by default, one 
uses Ajp13Connector, one uses CoyoteConnector:

 
 

 
 

You want the first one, not the second one.

Problem with mod_jk and admin application in Tomcat 4.1

[J.P. Wadkin C9951627]

It seems that it's not possible to use mod_jk with the admin application
in Tomcat 4.1

On startup this appears in catalina.out

ServerLifecycleListener: Creating MBean for Service
StandardService[Tomcat-JK]
ServerLifecycleListener: Creating MBean for Connector
[EMAIL PROTECTED]
ServerLifecycleListener: createMBeans: MBeanException
java.lang.Exception: ManagedBean is not found with Ajp13Connector
   

So I edited the mbeans-descriptors.xml file in the catalina.jar and
added an mbean for the Ajp13Connector. Tomcat started fine (no errors)
but mod_jk no longer works - any request to a webapp URL results in a
404 error. There's nothing in the logs - just the 404 errors. I'm not
sure why this is - there's a mbean for the Coyote/jk2 connector so
presumably this works?

You're using a sledgehammer where a light tap will do fine.

Either don't use MBeans, or use CoyoteConnector instead of

You're using a sledgehammer where a light tap will do fine.

Ajp13Connector doesn't like MBeans, or vice versa.

Either don't use MBeans, or use CoyoteConnector instead of 
Ajp13Connector.  The latter is preferred and recommended, Ajp13Connector

Re: Problem with mod_jk and admin application in Tomcat 4.1

[John Turner]

I didn't mean mod_jk2.

I meant CoyoteConnector in server.xml.

In server.xml, you have a connector listening on some port (like 8009) 
for communications from Apache.  This connector has a class parameter. 
In your case, the class is "org.apache.ajp.tomcat4.Ajp13Connector".

Make it "org.apache.coyote.tomcat4.CoyoteConnector" instead and you will 
be able to use MBeans.

CoyoteConnector can handle AJP13 from either mod_jk or mod_jk2, as well 
as HTTP and HTTPS.

There are actually two Apache connectors in server.xml by default, one 
uses Ajp13Connector, one uses CoyoteConnector:



protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>



You want the first one, not the second one.

RE: Problem with mod_jk, tomcat 4.1.18, apache 1.3.26, on FreeBSD 4.3

[Benjamin Hart]

I did try doing this as well, but ran in to problems with the linux
emulation libraries (I think, new to freebsd). Having followed the
instructions to make a diy mod_kj.so, this is the error I got:

Cannot load /home/y/libexec/mod_jk.so into server:
/home/y/libexec/mod_jk.so: Undefined symbol "jk_set_log_format"

Admittedly, I haven't hunted round very much for the causes of this error
yet. One thing that dissuaded me from doing so was the difference in the
file sizes, in case something was missing or had not compiled correctly: the
d'loaded ones were ~370kb, and mine was ~70k.

Cheers,

Ben

Are you comfortable with rolling your own connector?  It's been years since
I messed with FreeBSD, but assuming that you have a "sane" dev environment,
compiling the .so is pretty straight-forward.

Problem with mod_jk, tomcat 4.1.18, apache 1.3.26, on FreeBSD 4.3

[Benjamin Hart]

Hi,

I've been unable to set up the ajp13 redirect for servlets between my apache
and tomcat on freebsd, despite trying everything! The error I am getting is:

Cannot load /home/y/libexec/mod_jk.so into server:
/home/y/libexec/mod_jk.so: Undefined symbol "ap_hook_post_config"

Having looked around, this is highlighted for when migrating a module from
apache 1.3 to 2, but I am not running 2 here. I have tried all versions of
the mod_jk.so available from the jakarta site :(

I have done this before fine on both solaris and linux, but am having
problems here on freebsd. I am not desperate to use tomcat 4, so if somebody
has got this running with tomcat 3.3 I am happy to use that. I have to use
apache 1.3.26.

Manks thanks in advance,

Ben

Can you not encode the URL for the session and pass this URL as the
argument to the JavaScript for opening the new browser window?  Presumably
the URL will be rewritten if necessary, or not if the user has accepted
the cookie...

The cookie is being propagated. But it has a different content than this one 
that we get when using the warp connector.  Why?

That is not possible I think. I have to type in the url by hand and it works 
with the arp connector.

I think the problem comes from the mod_jk. I searched the documentation for 
some options but found nothing.

The session cookie is probably NOT being propogated in IE's new window.

If that is the case, then you need to add the session id to the url. 
(Via response.encodeURL( ... ) or response.encodeRedirectURL( ... ))

Your apache server might not have support functionality for dynamic
modules.. try recompiling your apache with enable_module=so.. it might work.

as for the path stuff, you can give your apache the full path name, like
/usr/local/apache/libexec/ although I think the default path Apache-Win
should be /usr/local/apache/modules/.. (I am not sure though... i use
linux...)

Good luck!

R: problem with mod_jk

[Christian]

I check in to the freebsd ports but I not find jdk 1.3.1, for freebsd
4.5 I find only jdk1.1.8.

I try to your configuration the error not change:

Syntax error on line 1 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/libexec/apache/mod_jk.so into server:
Cannot open "/usr/local/apache/libexec/apache/mod_jk.so"
/bin/apachectl start: httpd could not be started

naturally on line 1 there is the line that load mod_jk.so

Tell me your setup ? what version of Apache , what version of Tomcat, 
did you build the mod_jk ? Are you using any of the ports to build this

R: problem with mod_jk

[Christian]

mod_jk.so is in /usr/local/apache/libexec and I start first tomcat with
shell script startup.sh and apache with apachectl when tomcat are
started.

The problem Isn't resolve.

This is the usual error:
Sintax error on line 8 of /usr/local/tomcat/conf/mod_jk.conf-auto:
Cannot load /usr/local/apache/libexec/mod_jk.so into server:

Christian ,
Are you sure mod_jk got to /usr/local/libexec/apache ?
By default it goes to /usr/local/libexec .
Ernst has a port build for mod_jk, however I use mod_webapp.
Look and see if mod_jk is in /usr/local/libexec or
/usr/local/libexec/apache

also make sure to use apachectl stop , then start tomcat and then 
apachectl start

If you just want to build from the ports , it works fine.

Problem with mod_jk ajp13 talking to Tomcat 4, authentication always fails

[Richard Sand]

Hi all- I've encountered a potential bug in mod_jk.  I have a default
installtion of Apache 1.3.14, mod_jk, and Tomcat 4.0.1 on Windows 2000.
mod_jk is talking to Tomcat via ajp13.  Tomcat is (as default) listening on
8080 for its HTTP interface and on 8009 for ajp13.

The problem is this: when I access to Tomcat manager application, i.e.
http://myserver/manager/list, I get properly challenged to log in, but my
username and password never work, and Tomcat eventually says I am
unauthorized.  If I then access the same resource directly through Tomcat,
i.e. http://myserver:8080/manager/list, I get access with no problem.

The problem could be in mod_jk, although I suspect it may lie in Tomcat's
ajp13 listener (simply because mod_jk is older and more widely used, whereas
Tomcat 4 is newer).

Has anyone else seen this problem, or can someone else reproduce it?

Thanks!

Best regards,

Richard

OK, that's what I was afraid you would say...I was hoping that if Apache

Strange problem with mod_jk (desperate for help)

[Brandon Cruz]

I have installed mod_jk to connect Apache to Tomcat.  This was a
module obtained from jakarta's web site.  Apache and Tomcat will both start
up with no problem, but I am getting a 404 error when trying to access a
*.jsp page.

1)I have this exact same configuration with Tomcat 3.2.1, all I am
trying to do is put Tomcat 3.2.4 into the same environment on a new machine
(newer version of Linux also).  

2)My mod_jk.log is telling me that it finds a match for a worker,
here is the output when I try to access the page...
[jk_uri_worker_map.c (344)]: Into
jk_uri_worker_map_t::map_uri_to_worker
[jk_uri_worker_map.c (406)]: jk_uri_worker_map_t::map_uri_to_worker,
Found a match ajp12
[jk_worker.c (123)]: Into wc_get_worker_for_name ajp12
[jk_worker.c (127)]: wc_get_worker_for_name, done  found a worker

3)My apache error_log is telling me something about a segmentation
fault, which my properly working environment spits out sometimes (doesn't
ever cause any problems that I know of).  Here is the output...
[Wed Dec 12 23:56:02 2001] [notice] child pid 7385 exit signal
Segmentation fault (11)

4)Apache appears to be loading the mod_jk correctly on startup based
on the information provided in the apache error_log provided below...
[Wed Dec 12 23:07:47 2001] [notice] Apache/1.3.19 (Unix) mod_jk
mod_perl/1.24_01 mod_throttle/2.11 PHP/4.0.6 FrontPage/4.0.4.3 mod_ssl/2.8.3
OpenSSL/0.9.6b configured -- resuming normal operations

5)To me, this appears to be a problem with specifying a wrong path
for a context or something in server.xml, but I have checked that over and
over and it all is correct, but here is the path to my vhost in case I am
missing something.

 
 crossContext="false"
 debug="0"
 reloadable="true"
 
  



I know this is long, but if anyone can point me in the right
direction, I would REALLY appreciate it!  I have been working on this
configuration for 2 days now, am so close to completion, but have come to a
dead end.  Should I try to compile mod_jk on my machine?  Every attempt at
that has resulted in apache not starting up.

Any Help ? Thanks .

problem with mod_jk

[Tsinwah Lee]

Hi, my admin has config Apache to work with Tomcat, she said using Apache + Tomcat 
together, the jsp/servlets will load faster, but the static pages will "hesitate" for 
a fraction of a second and then the pages got load up. Also, the size of the log file 
for mod_jk has increased to 3MB by just using Apache + Tomcat for about 20 minutes. I 
checked with the mod_jk.conf and mod_jk.conf file, the jkLogLevel is "warn", and in 
the mod_jk.conf-auto file, the jkLogLevel is "error". Both of them are not on the 
"debug" level. I wonder why the size of mod_jk.log is that large.
So does anyone experience something like that? Or does anyone know how to optimize the 
performance for both static pages and servlet when using Apache + Tomcat? Thanks in 
advance.

Take a look at your mod_jk.conf.
For example check the JkMount command and LogLevel

[Nick Stoianov]

the problem is not only with the servlets - even HTML pages get loaded
really slow

Re: huge problem with mod_jk and Apache

[anil]

Hmm. That is strange. I run Tomcat 3.2.2 with
JBoss+postgreSQL+Apache+security on (every call gets autheticated) I
can't complain on Dell 800MHz server with 128MB of RAM with RedHat 6.2.
The JDK is Sun JDK 1.3.1.
Apache connector is Mod_jk12.
Email me the the servlet and I will try to run on my server.

huge problem with mod_jk and Apache

[Nick Stoianov]

Hi,
 
I have a Linux server running Apache and Tomcat 
3.2.2 (using mod_jk). I noticed that when I run Apache with mod_jk - Apache 
serves the html pages extremely slow (20 seconds for a simple page). If I 
disable mod_jk - it's  fast again.
 
I will really appreciate if somebody helps me with 
this problem.
 
Thanks
Nick

On 1.
Invoke servlet will go where you tell it to go.
Examine  URL-PATTERN under \conf\web.xml:

  
  
invoker
/servlet/*
  

Hope this helps

problem with mod_jk and Tomcat

[Nick Stoianov]

Hi,

I have the following problem. I was running Apache JServ and decided to 
upgrade to Tomcat with mod_jk and Apache. The installation went well. The 
sample servlets and JSPs work well. But now I'm having the following problems:

1. My old servlets that were working with Jserv don't work with Tomcat. I 
tried to find the reason and I found out that to invoke the servlets you have 
to go to http://localhost/servlet/the_name_of_the_servlet
Okbut my servlets have redirections to http://localhost/servlets (not 
servlet) .  I changed the JkMount in mod_jk.conf to mount /servlets for the 
servlet files. But it still doesn't work. 
My question is: how can I make tomcat to look for servlets in /servlets (not 
in /servlet)?

2. When I try to run the /admin JSP page I get ERROR 500: 
javax.servlet.ServletException: URL contains encoded special chars


I will really appreciate if someone helps me with these problems.

Hi,
I have had the same problem, with Apache 1.3.20 and Tomcat 3.2.2.
I recompiled Apache with "DSO support" and the error disappeared.

Hope this hint may help you.

That's all the magic of TCP IOs. You can connect, but you're not
sure that the remote server is ready to process your query.
Something which will be removed in AJP14 by the LOGIN feature.

Another "beauty" of socket API is that you couldn't be sure 
the write() call was really successfull before doing a read()
call.

Which make me think that when servicing a request we must add
somewhere a 'kind of timeout' in operation. But that complexify
also the process, since you had to play with NON-BLOCKED IO...

Ok, I'm using TC 3.2.2b5 and 3.3m3.

mod_jserv appears to be in end-of-life. No
more actively supported. I'd rather like see your
bug-report about the current apache tomcat connector
(mod_jk)

I used this one in production, it's stable and all
mod_jk bugs are fixed against this one since the
TC 3.2 is +/- closed for developpement (only fatal
bugs are to be fixed)

Re: lb-problem with mod_jk: high cpu load on apache when tomcat breaks down

[Timo Carl]

The problem has been seen on both, ajp13 and ajp12. 
We use tomcat-3.2.1.

What do think about using mod_jserv again?
What kind of quality has the T3.3 cvs mod_jk? Is it possible to use it
in a productive environment?

Greetings,
Timo

Re: lb-problem with mod_jk: high cpu load on apache when tomcat breaks down

[Timo Carl]

>I'm still waiting for the same answer
>as you do, for the high CPU request of mod_jk...

Yes, so I do.
I did not find any article or post about that problem. So I did not
check out mod_jserv. Before tomcat, we use jserv without problems. I
think, we will give mod_jserv a chance.

It seems to be a lifelock in mod_jk, because tomcat accepts the
connection, but is not able to reply. I think its that while-loop in
mod_jk:

static int ajpv12_handle_response(ajp12_endpoint_t *p,
  jk_ws_service_t *s,
  jk_logger_t *l)
{
while(1) {
unsigned to_read = READ_BUF_SIZE;
unsigned acc = 0;
char *buf = NULL;

if(!jk_sb_read(&p->sb, &buf, to_read, &acc)) {
jk_log(l, JK_LOG_ERROR, "ajpv12_handle_response, error
reading
 from \n"); return JK_FALSE;
}

if(!acc) {
jk_log(l, JK_LOG_DEBUG, "ajpv12_handle_response, response
body is
 done\n"); break;
}

if(write_to_ws) {
if(!s->write(s, buf, acc)) {
jk_log(l, JK_LOG_ERROR, "ajpv12_handle_response, error
 writing back to server\n"); write_to_ws = JK_FALSE;<<<<<<<<

lb-problem with mod_jk: high cpu load on apache when tomcat breaks down

[Timo Carl]

Hello tomcat-users,

We are having a problem with mod_jk and load balancing. 
Does anyone else have had similar problems with that kind of
architecture setup?

Our System:
===
Alteon switch (round robin)
|
|
three Apache 1.3.19 on three SPARC-Servers (called s1,s2,s3)(3 CPU, 3
GB)
|
|each:
mod_jk with lb (in case of s1: 1*s1,0.001*s2,0.001*s3)
|
|
|
two tomcats-3.2.1 on each server (jdk1.2.2, native threads, -Xms50M
-Xoss4M -Xss4M -Xmx600M)

We chose this architecture because the alteon is not able to perform
session tracking properly.

The Problem:

On startup, the system works fine. Each java-Process has about 1-8% CPU
load.
After one day or so, one tomcat takes 40% CPU load or more. I think the
reason is inside our applications. But thats not the error I want to
post:

After the error of a tomcat, the httpd-processes on EACH Server begin to
take a lot of CPU time (8-30% each).
In server-status I can see that the processes are waiting for a response
of that tomcat.
Of course I want to have a fault tolerance, but when I have a problem
with one server, the other servers go down too.


Did/Does anyone have the same problem and/or a similar system
architecture?
Maybe anyone solved that problem?

Greetings and thanks in advance,
Timo Carl

Re: Problem with mod_jk build

[Jeff Kilbride]

Hi Brandon,

First of all, did you download the *source* distribution for Jakarta? In
order to compile your own mod_jk.so, you need the source distribution --
jakarta-tomcat-3.2.1-src.tar.gz.

When you have the source untarred, cd into the source directory and then to:

src/native/apache1.3/

In there you will find Makefiles for different systems. Rename the correct
one for your system from Makefile.system to just Makefile. Then run the
command 'make' in that directory. If everything is ok, mod-jk.so will be
made for you in that directory. Copy it to your apache/libexec and update
your httpd.conf (or include mod_jk.conf into your httpd.conf...)

It's pretty easy and it worked for me the first time.

Thanks,
--jeff

Re: Problem with mod_jk build

[Scott Tatum]

Do you have these lines, either in mod_jk.conf or httpd.conf

LoadModule jk_module  libexec/mod_jk.so
AddModule mod_jk.c

You shouldn't be able to start Apache without them. You should get unknown
directive errors. Make sure those are in there somewhere (I recommend putting
them in httpd.conf along with all the other module loads).

Also I recommend copying mod_jk.conf-auto to mod_jk.conf, and including that
file from httpd.conf.

What kind of errors are you getting on Apache startup?

RE: Problem with mod_jk build

[Brandon Cruz]

I really need some help quick!!!  When it is telling me to use this command
to build mod_jk...

apxs -o
mod_jk.so -I../jk -I/usr/local/jdk/include -I/usr/local/jdk/include/linux -c
*.c ../jk/*.c

Does that mean that I need to substitute something in for the *.c?  It keeps
telling me that  gcc: *.c no such file or directory

If anyone knows what is going on, please help, I am very frustrated with
this, have been working on it for 2 days.

Thank you!

Quick question...
If I have a binary version of mod_jk.so, do I have to build it?  It said it
is already built for Linux, but I can't get apache to start when I put that
into apache's libexec directory and include the mod_jk.conf-auto.  What am I
doing wrong?  I have tried to build mod_jk, but get all kinds of errors
telling me that files do not exist.

I tried to add -lresolv without success. Finally, I patched jk_util.c to
use ap_snprintf and ap_vsnprintf :
diff ../jk/jk_util.c.ORG ../jk/jk_util.c
212a213,214
> #elif defined(IRISA) //Pb edition de liens
>   used = ap_snprintf(buf, HUGE_BUFFER_SIZE, "[%s (%d)]: ", f, line);
224a227,228
> #elif defined(IRISA)  //Pb edition de liens
> used = ap_vsnprintf(buf + used, fmt, args);

Command line to compile :
apxs -o mod_jk.so -DSOLARIS -DEAPI -DIRISA -I../jk -I/soft/jdk/include
-I/soft/jdk/include/solaris -c *.c ../jk/*.c

It's ok now.

Yes, I used apxs with and without -lposix4 : same problem.
I found in archive a message about this problem (on alpha, not
sun-solaris), but no answer :-(

Problem with mod_jk

[Philippe Lecler]

Hello,
  I installed tomcat 3.2.1 on solaris 2.5.1, it's OK.
  I compiled mod_jk with gcc-2.8.1, but when I trie to restart
  apache 1.3.19 I have the following message :

  Cannot load /soft/apache/libexec/mod_jk.so into server: ld.so.1:
/soft/apache/bin/httpd: fatal: relocation error: file
/soft/apache/libexec/mod_jk.so: symbol snprintf: referenced symbol not
found

snprintf is referenced in jk_util.c and is defined in libc.

Thanx in advance for any response.

If you using mod_jk on Linux i386 there is allready built
binaries for std-api / ext-api (EAPI)

Same thing happened to me.  It's been discussed here quite a bit lately.
Best thing to do is get the source from the tomcat site, follow directions
for building in the mod_jk howto ...

Hi,

As a newbie concerning tomcat, I am facing some configuration-problems:

I am trying to make tomcat work with apache on my linux-box.
I wanted to use tomcat 3.2.1 and apache 1.3.14 with mod_jk.  So the
problem is that
the apache doesn't want to recognize the module (that I downloaded as a
binary from
the jakarta-site)  as an apache DSO.
I followed the instructions from the mod_jk-how-to and  included the
.conf-auto file,
that is generated by tomcat after startup, into apache's httpd.conf.
But when apache reaches the instruction, it exits with :

API module structure `jk_module' in file
/opt/apache_1.3.14/libexec/mod_jk.so is garbled - perhaps this is not an
Apache module DSO?

What is wrong ? Are there any restrictions on versions that are not
fitting together ?

JkMount does not work in the same way as ApjServMount

JkMount /context worker

worker != URL
take a look at the docs

problem with mod_jk

[Victor Louis]

Hi,

I was using tomcat with apache+mod_jserv on Redhat 6.2. Now I upgraded to
mod_jk from mod_jserv. The scenario is I am hosting multiple sites on my
intranet server. Earlier I was was using ApJServMount for  mounting on
different ports like in the following lines and each site had its own
server.xml  (server_das.xml...) and tomcat startup files.
ApJServMount /das   ajpv12://localhost:8009/das
ApJServMount /formsajpv12://localhost:8012/forms
ApJServMount /intranet ajpv12://localhost:8016/intranet

Now with mod_jk if I give the following line in mod_jk.conf it is not
working.
JkMount /das/* ajp13://localhost:8009das

Has anyone has any hints or solution regarding it ?. Please do mail to it
me.

Thanks in advance

Best regards,

Victor Louis
