I put in the following config in httpd.conf

LoadModule jk2_module modules/mod_jk2.so

<Location "/*.jsp">
JkUriSet worker ajp13:xxx.x.201.108:8009
</Location>

<Location "/scrmypm">
JkUriSet worker ajp13:xxx.x.201.108:8009
</Location>


I put this in workers2.properties, same dir as the httpd.conf

[shm]
file=/etc/httpd/logs/shm.file
size=1048576

# socket channel
[channel.socket:xxx.x.201.108:8009]
port=8009
host=xxx.x.201.108

# worker for the connector
[ajp13:xxx.x.201.108:8009]
channel=channel.socket:xxx.x.201.108:8009


The tomcat conf/server.xml file I put this at the end
<Context path="" docBase="/var/www" debug="0" reloadable="true" crossContext="true"/>

Lastly I put this in conf/jk2.properties
channelSocket.port=8009


Did i miss out anything? I already install the mod_jk2 rpm for RH9. The mod_jk2.so file is in the modules dir in apache.
Thanks a lot.

I manage to get the config working now. I can display a jsp page sucessfully in apache. I still have some queries though. After i startup apache, i view the error_log file of apache and found this messages at below. I dont know whether its error or is it suppose to be like this. If its error how can I solve it.
