Coldfusion RDS 404 error on OSX

August 22, 2014

When running Coldfusion on OSX with RDS enabled you may receive a 404 error when trying to connect your IDE (CF Builder, Homesite, etc.)

After reviewing permissions and configuration I found that the issue was Apache checking for the existence of the page prior to attempting to run it. The RDS IDE functions/page does not exist because it simply a URL pattern defined in the web.xml file.

An easy fix was to setup a dummy folder/file:


The IDE.CFM page can be blank, Apache just needs to verify the file exists prior to handing it to the Java server for processing.

Thank you! This helped tremendously and allowed me to get RDS working with HomeSite+ on ColdFusion 11

Brilliant - thanks so much. Saved me a packet of time with CF11 and CFB3
