And followed the instructions. When running glassfish, I see that
-Dcom.sun.enterprise.web.connector.enableJK=8009 is set.
I opened the source code and saw PEWebContainer.java which says that
if the property is set, then this should appear in the log:
Apache mod_jk/jk2 attached to virtual-server
Nothing like that. And port 8009 is not listened to.
