Subject Re: Problems with mod_jk2
Date Wed, 25 Jun 2003 00:28:35 GMT
Good morning Eric.
The setting format for 'config.file' at least confirms what a trowel through
the source code turned up. Thanks.
The 'TomcatID' parameter is also alternately named 'route' in mod_jk2, and
is, I think, used mostly in load-balance situations, where, at the Tomcat
end, it is called 'jvmRoute' on the <Engine element.
The port and address are not 'normally' needed as mod_jk2 will also use the
channel.socket name elements [channel.socket:<host>:<port>] for these
parameters... (which is not entirely kosher in my view). Hence the clearest
method would be to include both the port= and host= parameters under the
[channel.socket:.....] section.
I _think_ this helps.
Norm
