Problem with Name Virtual Hosting, Jk, Apache 1.3.27 and Tomcat 4 .1.18

["Gerstel, Rachel" <Ra...@commerzbankib.com>]

Hi All,

I am having trouble with Name Virtual Hosting for Apache 1.3.27 and tomcat
4.1.18 and mod_jk. Maybe someone can see something that I have overlooked.
And I apologize ahead of time if this is jumbled, but I have been at this
all day and my brain is pretty fried. :--)

I have one server with four name-based virtual hosts:
host1-app1
host1-app2
host1-app3
host1-app4

Only one of them needs tomcat - host1-app4. I tried adding/loading the jk
module in my httpd.conf directly and putting all the jk directives in my
virtual host container for that app, but then I got errors in my
/var/apache/logs/error_log saying:
[Thu Mar 27 18:22:27 2003] [error] Error while opening the workers, jk will
not work
[Thu Mar 27 18:22:28 2003] [error] (2)No such file or directory: Error while
opening the workers, jk will not work

So I am guessing that there was something wrong with the config. But, If I
just take out the jk directives (also removing the load/add module for jk),
put them in an include file and load jk from there then I get no errors. The
only problem is that then I get no page displayed when I try to go to one of
the pages which should be served by cocoon for host1-app4. 

log messages from mod_jk.log:
[Thu Mar 27 18:44:07 2003]  [jk_uri_worker_map.c (460)]: Into
jk_uri_worker_map_t::map_uri_to_worker

[Thu Mar 27 18:44:07 2003]  [jk_uri_worker_map.c (599)]:
jk_uri_worker_map_t::map_uri_to_worker, done without a match

And you can see in apache error log that it is looking in the doc root
rather than tomcat:

Re: Problem with Name Virtual Hosting, Jk, Apache 1.3.27 and Tomcat 4 .1.18

[John Turner <to...@johnturner.com>]

All of your JkMount statements need to be within the VirtualHost container 
for host1-app4, the one where it says "ServerName host1-app4.com".

Global JkMounts don't do much, and only work for Apache's default 
ServerName, which, in a virtual hosting environment, probably isn't going 
to help much.

For each VirtualHost where you have requests going to Tomcat, you want 
something like:

JkMount /*.jsp ajp13
JkMount /servlet/* ajp13

or:

<VirtualHost *:80>

 ServerName host1-app4.com
 DocumentRoot /var/apache/htdocs/app4

 JkMount /admin ajp13
 JkMount /admin/* ajp13

 JkMount /cocoon ajp13
 JkMount /cocoon/* ajp13

 JkMount /DerivativesAdminWebsite ajp13
 JkMount /DerivativesAdminWebsite/* ajp13

 JkMount /manager ajp13
 JkMount /manager/* ajp13

</VirtualHost>

I'm not clear what mod_jk.conf.hardcopy is exactly...if its output from an 
ApacheConfig Listener in server.xml, then you don't need to do anything at 
all, as it will have the appropriate Apache VirtualHost containers already 
in it. Basically, don't setup a VirtualHost container in httpd.conf for JK 
directives, and then another VirtualHost container for the actual virtual 
host definition...the JK directives that apply to that virtual host need to 
be in that virtual host's VirtualHost container.
