IIS and Tomcat on the same box?

Could you get your pages directly from Tomcat via its http connector
(8080 or so)?

So does it

- work never
- work sometimes, but sometimes not?

Which URL did you use, what's exactly in the log file?

Should be available under the URL /jkmanager and is very helpful.
There's a security problem with an open jkstatus though.

So you need to find out the port numbers (and if on different hosts the
host names) and define two workers ws and ps in the way you have done
with ajp13w.

Define the ws and ps workers with correct host names and ports, wrap
them in a new lb, like lbps and lbws


and put lbps resp. lbws behind the equal sign in the lines of you want to be mapped to ps resp. ws.
