mod_jk and URL rewriting/proxying?
Hi List
I have a quick question (I hope).
I'm using mod_jk to forward from Apache httpd 2.2.8 to tomcat 7.0.20
(Ubuntu 8.04). I think I saw something on this list some time ago but
can't remember what it was really about (the real issue was not want I
want to do).
So I want users to access my webapp from xxx.yyy.zz and then have
apache/mod_jk to change it to xxx.yyy.zz/myapp
According to
http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html I have
to manipulate headers but as far as I remember there was something about
ProxyPass and ProxyPassReverse. Are they only available to mod_proxy or
mod_ajp?
I don't want the app to become ROOT since I have another app that should
be running as ROOT. I thought about making seperat host's in server.xml
but I dont like the fact that I need to restart tomcat each time I need
to add a new host so I thought I might achieve want I want by letting
apache httpd take care of that part.
Kind regards
Casper

Yes, those can currently not be combined with mod_jk. Sorry.

You might want to look at the host-manager webapp.

The host manager webapp is in the main part of the TC code, but it's
all contained in a single package: org/apache/catalina/manager/host.
It's 3 classes, one of which looks like it's nothing but constants.
It should be fairly clear how the host manager is doing its work, but
re-writing XML is a risky business because most people don't like to
lose the comments and spacing, etc. that they have explicitly put into
their configuration files.

Look for the digester package to see how Tomcat reads from server.xml.

Well at least I don't have to restart tomcat for the changes to take
effect :) Maybe I would take some time to look at how tomcat reads from
server.xml and how the host-manager works and perhaps find a way to
persist the changes :) Any clues as to where to look for that part of
the code?

IIRC, the host-manager won't save the server.xml back to disk, so
you'll have to remember to update your server.xml whenever you want to
hot-deploy a new domain name, anyway.

Ha my bad. I use separate subdomains. Right now the localhost-host uses
the default ROOT (the one shipped with Tomcat) but I plan to use another
webapp later.

Nice, that will be the thing to do then :)

Correct. There was some code that tried to do this back in 5.5.x but it
was buggy, not maintained and therefore got dropped.

A brief scan of the code indicates that you will have to maintain server.xml yourself. All I could see was code that manipulates the active objects; nothing seems to be persisted.

Chuck -
Does the host-manager persist changes now, or is it still running changes only?
That is, does one still have to modify the server.xml if we want new hosts to be there the next time we restart tomcat?

And how is that one accessed? From what you described it sounds like you want the same URL to hit different webapps based on the mindset of the user.

Restart not required; use the host-manager webapp to add them on the fly.
