Tomcat and URL rewriting
Does tomcat support ANY URL rewriting functionality similar to Apache's mod_rewrite but using stand alone Tomcat 4.1.24 without Apache? Many thanks! Jamey
RE: which jk2 to use
I've had problems with the 4.1.24 src release occasionally losing communication with the Tomcat. I haven't fully debugged these yet but I'm suspicious of it. I've also heard from others that the releases of mod_jk and mod_jk2 to use are those released with the connectors project, not with Tomcat. Thus I'd suggest the 2.0.2 release of mod_jk2 though I'm in the process of testing it and can't tell you that it's definitely better. Another option might be mod_jk 1.2.4 which I'm also trying out in hopes of solving my 4.1.24 mod_jk2 problems. Best of luck.

Subject: RE: Could you give some help for me (about mod_jk for solaris 9)
This worked for me on Solaris 8 this evening:
Make sure you have properly compiled and installed Apache 2.x and Tomcat 4.1.24.
We'll call these installation directories apache2.home and tomcat4.home.
Also make sure you have recent versions of m4, automake, and autoconf installed from
www.sunfreeware.com.
Set the environment variable M4 to the location of your GNU m4 executable.
For example in bash: export M4=/usr/local/bin/m4
Download jakarta-tomcat-connectors-jk-1.2.4-src.tar.gz from
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/release/v1.2.4/src/
and extract it to some directory, well call it jk.build.
cd ${jk.build}/jk/native
execute buildconf.sh
execute ./configure --with-apxs=${apache2.home}/bin/apxs
execute make
Locate mod_jk.so from the ${jk.build}/jk/native/apache-2.0 directory and copy it to
your ${apache.home}/modules directory. Just add the line
LoadModule jk_module ${apache.home}/modules/mod_jk.so
to your ${apache.home}/httpd.conf file and follow the configuration instructions for
httpd.conf and workers.properties given at
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/release/v1.2.4/doc/.
Good luck!

RE: jk2.properties
Thanks Simon. It's just odd that it's settings don't override what's in server.xml or that you can set the same thing both places. I could see using jk2.properties for extended properties specific to each channel type but things like host and port that are specified in the server.xml are just confusing to repeat in jk2.properties.

RE: shm and jk2?
Let me answer that myself and see if anyone corrects me. Apache 2.0.45 is still a multiprocess application using the worker module. Thus, presumably eash process has a copy of the mod_jk2 endpoint in memory, all of which must remain in sync for certain operations thus requiring the use of shared memory and the shm file.

RE: How do I determine sessions within Tomcat?
Mark, Another option is to write a callback class that is registered with each session using the HttpSessionBindingListener interface. Each time a session is destroyed, either explicitly by the user or implicitly by Tomcat (user just closed browser) then your widget should have its valueUnbound method called and you could update your DB.

RE: PLEASE HELP - Apache mod_jk2 loses communication with Tomcat
Eric,
Isn't the ajp13 specified in the workers2.properties simply a designation of
protocol and not telling the client (Apache mod_jk2) which connector to use on the
tomcat side. It should only know host, port, protocol (ajp13 vs ajp12).
Again, although I see the sytax differences in our two workers2.properties
configurations I don't see the logical differences. The mod_jk2 assumes a lot from
the naming convention of the workers and it is possible to create a configuration
using a very minimal amount of text in a workers2.properties but I went with the more
explicit approach which should be logically equivalent. Can you site any specific
instances where your configuration is logically different from mine?
Is using the 2.0.2 build of the connectors preferable to using the build
distributed with Tomcat 4.1.24 which I used? What kind of a user load does your
mod_jk2 configuration handle on a daily basis? How many concurrent sessions do you
run per application server, etc?
Thanks again for your help!
Jamey

I'm still puzzled though. I don't really see any difference in
what you're doing vs. what I'm doing. I explicitly specify host and

particular in my workers2.properties which is actually not correct?
I'd look closer. There are quite a bit of differences.
Please recall that my cluster works for a time and then
communication falters between the servers. This doesn't seem like a
config problem as a config problem would probably preclude things
working correctly in the first place.
I'm not so sure about that. But I would start with the low hanging fruit
first. My JK2 has worked fine for day. In fact in another thread we
were talking about how mixing Ajp13 and Coyote causes unexpected errors
and general freaky-out-ness with no explanation what so ever. I notice
you declare ajp13 in your workers2.properties file as part of the channel.
Is the general opinion that mod_jk2 is ready for production use or
is it likely still a little rough? I'm having a lot of trouble getting
mod_jk to work though as an alternative. I'm using the release of
mod_jk(2) from the Tomcat 4.1.24 release which can be found at:

John, I was simply making the assumption that the connector code released with Tomcat 4.1.24 had been tested and validated to be at a stable point for that release. I understand that there are two parts to the code and that the connectors are a separate project. What I want to know is: 1) Does anyone know why my mod_jk2 configuration posted below fails intermittently. I wouldn't be asking any of this if it were working reliably. 2) Is mod_jk or mod_jk2 preferred for stable production use with moderate user loads (100-250 concurrent sessions per Tomcat, 2x Tomcat, 5-10 req/sec for the apache 2.0.45). 3) Which code release of mod_jk or mod_jk2 should I use if not the one released with 4.1.24?

RE: PLEASE HELP - Apache mod_jk2 loses communication with Tomcat
Thanks Eric.
I'm still puzzled though. I don't really see any difference in what you're
doing vs. what I'm doing. I explicitly specify host and port for the channel sockets
and I explicitly define the workers but that's shouldn't make any difference should
it? Is there anything in particular in my workers2.properties which is actually not
correct?
Please recall that my cluster works for a time and then communication falters
between the servers. This doesn't seem like a config problem as a config problem
would probably preclude things working correctly in the first place.
Is the general opinion that mod_jk2 is ready for production use or is it
likely still a little rough? I'm having a lot of trouble getting mod_jk to work
though as an alternative. I'm using the release of mod_jk(2) from the Tomcat 4.1.24
release which can be found at:
http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.24/src/
Thanks!

You have to adjust it to your own needs. You can change 'localhost' to

mod_jk and Coyote connector
Not that I've had any luck getting mod_jk to work with either the legacy Ajp13Connector or the CoyoteConnector but which one should be used? I know that the CoyoteConnector is required for mod_jk2 and I've had that working (mostly, occasional lapses in communication, see other messages to user list) but is it compatible with mod_jk. I'm using Apache 2.0.45 with Tomcat 4.1.24 and the mod_jk and mod_jk2 connectors were built from the Tomcat 4.1.24 connectors release found at http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.24/src/ Many thanks!

RE: Running a class on startup - java newbie....
EJ,
You can create an initialization servlet that get's loaded at startup of your
webapp. This servlet could create a thread that does what Andre suggests below. Use
the web.xml to configure any parameters you need to pass to this servlet and to ensure
it's loaded first. Then just define an init method for that servlet that creates and
executes your thread. You can use the servlet's destroy method to shut down your
thread.

If that's the case then I'd run it as part of the user addition process to ensure that
things are in the correct state for adding a user. No additional threads required (no
that they're bad when used correctly).

Honestly, I'm not even sure that the DB cleanup I'm trying to perform needs

Mod_rewrite and mod_jk2
Hey all,
We're using Apache 2.0.45 as a pure load-balancer for two Tomcat 4.1.24
instances. Apache serves no content and redirects /* to the Tomcats (using the uri
element of the workers2.properties). We have some rewrite rules that massage some
URL's based on the domain name the user is accessing our site with.
For Example:
RewriteCond %{HTTP_HOST} ^www.mysite.com
RewriteRule ^$ /some/url/mysite [PT]
RewriteCond %{HTTP_HOST} ^www.myothersite.com
RewriteRule ^$ /some/url/myothersite [PT]
We're and ASP and basically have customer specific URLS for our product which should
redirect the customer to the correct logon page for our app with their branding.
mod_jk2 seems to intercept all requests prior to mod_rewrite getting a crack at it.
Is there some way to let mod_rewrite get first shot at the URL before the urls are
handed off to tomcat?
Thanks!

mod_jk2 and shm
I keep getting errors like the following from my mod_jk2 installation. Everything seems to work fine but my apache_error log has errors relating to the shm worker which I don't even configure in workers.properties since I don't see that it's in any way required for a simple channel.socket configuration. My load balancing through Apache seems to work fine too so I'm pretty confused. I've inlined the errors followed by OS and Apache information followed by my workers2.properties. I'm using Tomcat 4.1.24. Should I be configuring Apache to use an on-disk scoreboard file and should I be configuring the shm worker to point to that file? I've tried this and the shm.init(): No file error goes away but that's it. Thanks ahead of time for the help!

RE: jk2_init() Can't find child xxxxx in scoreboard
Same here. Please keep us informed. Many thanks!

Did you ever figure it out? Thanks, -Mark Scott Ahten [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... I'm trying to setup Apache2 and mod_jk2 to pass Tomcat requests via JNI. After reading two or three HOWTOs and previously setting up a similar config on Windows 2000 server, I've managed to make some progress on RedHat 7.3. Unfortunately, when I start Apache2, I get an jk2 error message about every 2-5 seconds. Here is a example from a recent run.

This seemed to have no effect. Also, sending requests such as http://localhost/ stall without any additional errors any of Apache or Tomcat's log files. I'm guessing this has something to do with the scoreboard error, but may be because Tomcat isn't getting launched in-process with Apache. Removing the LoadModule directive for mod_jk2 allows the static Apache2 welcome page to load. In brief, Apache2 was built from source using.. ./configure --prefix=/usr/local/apache2 --enable-ssl --enable-module=so -- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
