CF10Std/RHEL6.3WS produces flex2gateway 404

I am trying to get ColdFusion 10 Standard 64-bit to install and run on 64-bit RHEL 6.3 Workstation (Apache). After disabling selinux, all segments of the installation run to completion flawlessly. There are no indications of any kind of error. The ColdFusion administrator appears to be functioning normally. The mod_jk.conf file is included in the httpd.conf file as required. In spite of this, any attempt to use Flash remoting results in a "Send Failed" message. In fact, any attempt to access flex2gateway results in a 404 page not found message (including http://localhost/flex2gateway/).

Other details that may or may not be relevent are as follows: I am new to Tomcat (I'm a long time ColdFusion 8 and 9 user) and I am not sure where to go to try to fix this problem. I am trying to migrate a web-site that features/contains LOTS of Flex 4.51 compiled controls from a 32-bit RHEL5.8 machine that is running 32-bit ColdFusion 8 Standard to the new 64-bit platform. The Flash/Flex controls were re-compiled with Flash Builder 4.6 specifically for the new 64-bit ColdFusion 10 platform. None of this really matters, though, as long as http:/localhost/flex2gateway/ returns a 404. Something is wrong with the installation itself.
