I need to alter a ColdFusion installation's ISAPI connector configuration to use a standalone, non-ColdFusion 64-bit Tomcat 7.0.59 installation, running a Grails application, as a second worker responding to a very specific URI.
A standard configration - changing uriworkermap.properties and workers.properties - is all I thought I'd need. This returned nothing but a 500 from the standalone Tomcat.
Knowing that 64-bit Tomcat requires the 64-bit DLL, I overwrote the stock ISAPI_redirect from the ColdFusion installation with the latest 64-bit ISAPI_redirect.dll from Apache.
Now my Tomcat application works fine, but ColdFusion serves nothing but a blank, white page. isapi_redirect.log says this when it tries to access the ColdFusion worker:
