Hello,
Thank you! I did compile the module myself, wanting to be sure it was
properly compatible with my target environments.
I'll mod the code and see what new information is logged.
Thanks.

Before line 2372 add the following lines:

Hello, See below. On Wed, Jul 14, 2010 at 12:13:11PM +0200, André Warnier wrote: Mmmm. Taking into account all previous communications, this looks really strange. It looks as if mod_jk is being called, is finding a match with its URI map, but then is not even making any attempt at contacting the Tomcat worker... On the other hand, assuming that your IBM webserver is some clone of Apache (which is what the configuration looks like), then I find your VirtualHost section rather strange. One would normally expect something like Listen 80 NameVirtualHosts *:80 ... VirtualHost *:80 ServerName localhost ... /VirtualHost I don't know if this could interfere with mod_jk, but maybe it does. The VirtualHost section was created by the ApacheConfig option in Tomcat. It actually creates a separate mod_jk.conf file that is to be included via an Include line, but I copied it into the httpd.conf file because I made some modifications to the original. That is just because unless I disable the auto config in server.xml, the conf file is regenerated every time Tomcat is restarted. The modifications were to comment out the mounts I didn't want to use, and add a DocumentRoot for local (non-jsp) files, as well as change the JkMount directive to point only to .jsp files.

Trivial question: are you sure, that your worker name is correct (worker1 vs. ajp13). I am curious, why Tomcat-generated configuration has different worker name. The auto configuration feature of Tomcat should be deprecated. It is of no real use except for a trivial starter configuration. It *always* uses a single worker named ajp13. Because of this feature (I guess because) mod_jk has a builtin worker named ajp13, which even if no worker named ajp13 is explicitely defined tries to contact localhost at 8009 if the a URL is mounted to a worker named ajp13. Legacy stuff. Nevertheless, although the config the OP uses is not sufficient for prime time, it should work. I didn't yet have the time to compare, where exactly the log lines stop compared with a working request. Hello, The evolution of this process is as follows. I am updating an Apache module with some additional functionality. This module is installed in two places, one an Apache 2.0 server and the other an IBM httpd server. In both instances, Apache is serving pages in front of a Tomcat server. Additionally, the module needs to run in multiple virtual hosts. Therefore, I have to recreate the production design locally, in order to be able to install my module and test my new additions. To install mod_jk, I resorted to my good friend Google, and used a tutorial to set up the connector. In that tutorial, the method used was to create a properties file (workers.properties) which set up the worker `worker1'. Failing to get that process working, I fell back to the ApacheConfig directive, given the possibility that I might be leaving out something simple yet critical in my `hand-rolled' method. I just changed the worker name back to `worker1' because I didn't want to keep fiddling with the conf files, and `worker1' was already in place. Really, I just used ApacheConfig to get something to compare to my existing setup. I really appreciate your taking time to look at this. It is such a huge time-waster for me. I'm spending more time setting up the test environment than on my code. I'm installing a clean version of Apache, built from httpd.apache.org sources, in /usr/local in order to get around all the weird (IMO) configuration for the version installed in Ubuntu by default.

I will not often say this, but I believe your problems may stem from the
above, and that you would do better by using the pre-packaged versions of
things (except Tomcat)
1) it is hard to judge the correctness of a tutorial found on Google.
The mod_jk instructions on the mod_jk pages of the Tomcat website are
pretty good, and they are at least accurate and up-to-date.
True. One of them was the `quick start for the impatient' on the
mod_jk doc page.
2) the standard Apache packages for Debian and Ubuntu are quite good, and a
lot easier to install and maintain than working everything out from scratch.
I suggest the following order :
apt-get install sun-java6-jdk
(then Tomcat, but for Tomcat, I suggest installing it from the Tomcat site
distribution)
apt-get install apache2
apt-get install libapache2-mod-jk
(the last 2 work out of the box and take max. 3 minutes altogether)
Then you just need to add a workers.properties file and your JkMount
mappings, and you'll be up and running in no time.
The weird configuration things you are mentioning for Apache, are quite
easy to follow once you get over the initial surprise, and are actually a
clever way to facilitate enabling/disabling modules and virtual hosts.
I offer to explain summarily, maybe off-list, if you have trouble there.
Well, it can't hurt for me to uninstall/reinstall to get things back
to a clean configuration.
Also, there's more to the weirdness of the Apache installation than
just the module/vh setup. First, they've arbitrarily renamed some
elements (e.g., replaced `httpd' with `apache2' in various places),
which serves no useful purpose. Second, `apxs' (renamed to `apxs2')
does not work correctly for compiling and installing my existing
module. Maybe it works if you create one from scratch, I don't
know. Nor does `apachectl' (renamed to `apache2ctl'). `apache2ctl'
fails sometimes with the weird message `bad user name
${APACHE_RUN_USER}', meaning I take it that this variable is not
properly exported unless you run `/etc/init.d/apache2'. Which only
takes `start|stop|restart|reload' for arguments. (And setting the var
in the shell does not work.) Third, you have files needed for
development/admin work in /etc/apache2, /var/lib/apache2 and
/usr/share/apache2 -- I mean, WTF?
For me, the summary of all that is that I installed the IBM server
into /opt and all the module-related stuff (apxs) and control stuff
(apachectl) just works. And I'm not giving props to IBM so much as
I'm saying that the design of the installation for Ubuntu was not
intended for usage as a development package.
/rant
I'll do as you suggest regarding the OOB installation and see where I
get. I spent most of today working on my module, so at least I have a
feeling of progress.
Thanks.

Request Processing by Apache httpd for Tomcat
Hello, I am working on an Apache module. The module is installed in an Apache http server that handles requests for a Tomcat server. When requests come from a mobile device, the jsessionid parameter is appended to the URI in the usual manner, e.g. /i/n_my_page.jsp;jsessionid=123adsfadsfsadf The above is how the URI appears in the apache server log file. My question is, Is this how the URI is stored in the request_rec object? I need to apply some logic based on the value of the URI stored in request_rec, so I want to be sure I understand how this value is created when Apache is running in front of Tomcat. Thanks for any help. mp -- Michael Powemich...@trollope.orgNaugatuck CT USA Which is worse: ignorance or apathy? Who knows? Who cares? pgpdTmppkN8G1.pgp Description: PGP signature

Hello,
See:
http://tomcat.apache.org/tomcat-5.5-doc/config/context.html
in particular, the section on antiResourceLocking. Note the caveats.
Otherwise, undeploy the app, update your jars, and redeploy.
Thanks.

Hi All,

in catalina.policy:
It might be possible, but it would be a *very* bad idea.
grant codeBase file:${catalina.home}/webapps/abcd/WEB-INF/lib {
permission java.io.FilePermission read, write, delete;
};
but it was giving following error:
java.io.FileNotFoundException:

Guess not then.
Is it smart for the application to try and delete it's own jar files?
