Hi folks,
I like to share a couple of experiences, which I learned the hard way
and I learned them, while trying to get Cocoon working through Apache.
They might have been obvious to someone else, but anyway.
First I tried mod_webapp. I configured it like this
<IfModule mod_webapp.c>
Include /etc/httpd/mod_webapp.conf
</IfModule>
while mod_webapp.conf contained the actual directives. The result was,
that it didn't work. Looking at /server-info I saw this:
Module Name: mod_webapp.c
Content handlers: webapp-handler
Configuration Phase Participation: Child Init, Child Exit
Request Phase Participation: Translate Path
Module Directives:
WebAppInfo -
WebAppConnection - [optional parameter]
WebAppDeploy -
Current Configuration:
No configuration visible. I think here is an issue with the include
mechanism. Then I configured it like this:
<IfModule mod_webapp.c>
WebAppConnection conn warp localhost:8008
WebAppDeploy examples conn /examples
WebAppDeploy cocoon conn /cocoon
WebAppDeploy scarab conn /scarab
WebAppInfo /webapp-info
</IfModule>
This showed the correct configuration in /server-info, but when I tried
/cocoon/welcome, after some period of burning cpu cycles, I received an
error message about some "internal error" (I used cocoon CVS shnapshot
from Tuesday). So, this didn't work. Perhaps someone else has other
experiences.
Then I moved to mod_jk. I had used mod_jk with tomcat 3.2 and cocoon
1.8.x. So, I had a configuration left apart from having moved on to
tomcat 4.0.1.
First lesson learned:
You need a workers.properties file for mod_jk. However tomcat 4.0 does
not include one. First I though: "Ah, simply set this to /dev/null,
it's not needed", but this didn't work. mod_jk needs the
workers.properties to configure the ajp ports correctly. Using one
from tomcat 3.2 made it work.
Second lesson learned:
Remove an "Alias" for cocoon, if you have one left in your httpd.conf.
My previous configuration from cocoon 1.8.x contained a line like
Alias /cocoon "/usr/local/httpd/tomcat/webapps/cocoon"
Selecting "/cocoon/hello.html" from the cocoon welcome page would
produce a 404 error, since apache tries to satisfy this request,
instead of passing it to tomcat.
Hope, this helps someone else.
