Going nuts with Tomcat 4, JK2, and IIS

[Phil Chuang]

I am going absolutely nuts trying to get Tomcat and IIS to play nice together. I think I've narrowed down the culprit to my jk2/workers2.properties files, as the IIS logs seem to show it connecting to the isapi_redirector2.dll, but returning an http error 500 (internal server error).
Someone please help me before my brain melts!
-------------
I am running tomcat in-process, so I made sure that it is not running when I start up IIS, and have verified that IIS starts it up correctly.
the ISAPI filter is configured correctly (at least, it's green).
jakarta virtual directory has been made and points to the directory of isapi_redirector2.dll
Here are my settings:
REGISTRY,
HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Jakarta Isapi Redirector\2.0

You know, if I had seen this line
------------------
# In order to enable jni use any channelJni directive
# channelJni.disabled = 0
------------------
a lot earlier I could have saved myself two days....
sigh.
