Configure Apache httpd.conf for struts requests

Question

Hi everyone,
I am not sure if this is the correct place to ask this question, but I have been struggeling with this for a number of hours over the past few days and can't get it to work. I have a standard Apache2-Tomcat installation on a solaris machine. I have apache configured to talk to Tomcat to mod_jk.so and it wokrs fine for servlets and jsp. Now I have introduced struts to the picture and Apache does not seem to know what to do with the .do requests. I have configured httpd.conf according to a bunch of articles/posts that I have found on the Internet. Here is what a snippet of it looks like:
# Load mod_jk module
# Update this patch to match your modules location
LoadModule   jk_module   libexec/mod_jk.so
# Declare the module for <IfModule directive>
#AddModule    mod_jk.c
# Where to find workers.properties
# Update this path to match your conf directory locaton (put workers.properties
next to httpd.conf)
JkWorkersFile /usr/local/apache2/conf/workers.properties
# Where to put jk logs
# Update this path to match your logs directory location (put mod_jk.log next to
access_log)
JkLogFile     /usr/local/apache2/logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel    info
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions indicate to send SSL KEY SIZE,
JkOptions     +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat     "%w %V %T"
# Send everything for context /examples to worker named worker1 (ajp13)
#JkMount     /examples/* worker1
JkMount     /*.jsp worker1
JkMount     /*.do worker1
JkMount     /ValidationManagement/* worker1
JkMount     /ActivityTracker/* worker1
JkMount     /Bars01/* worker1
JkMount     /Bars02/* worker1
JkMount         /RMIS/* worker1
JkMount         /Fars/* worker1
JkMount         /Training/* worker1
JkMount         /CoreDBSAP/* worker1
JkMount         /iul/* worker1
JkMount         /iul/*.do worker1
JkMount         /PIForm/* worker1Here is the contents of the workers file:
# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost
#worker.worker1.host=10.221.13.50
worker.worker1.port=8009
worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.recycle_timeout=300I have also tried thigns like AddHandler jserv-servlet .do which I know shouldn't work since I am using mod_js.so.
Can anyone help? I am in a crunch as I have to get this out to a client today. Thanks all!

Found this in the mod_jk log. So, it looks like it is trying to map to the right JkMount. WTF?

Answer 1

Ok, thanks for clarifying that. But, the poroblem still lies with Apache since that has to handle the incoming HTTP request and then forward that onto something that can handle the processing (in this case the servlet container Tomcat). Just like you have to tell Apache where to send requests to .jsp files, the same has to happen with .do. This piece seems to be working, but after it finds the worker it then doesn't know what to do. Clearly I am missing some setting that I have yet to find.
Thanks,
Nik
