Change the default JRun error message in ColdFusion

If your ColdFusion server (actually the JRun underneath CF) throws an error your stuck with a rather ugly and uninformative page telling people that you have an error. This is not what you want. Of course, having a JRun error is not what you want but if you have to have one, you'de rather people see an error message that at least looks nice.

This can be done rather easily using a setting in the jrun.ini file located in: C:/CFusionMX7/runtime/lib/wsconfig/1

On apache, the file is the mod_jrun.so located here: /opt/coldfusionmx7/runtime/lib/wsconfig/1

In these files you'll see a line formatted like this (in both CFMX 6 and 7) #errorurl=

All you have to do is remove the pound sign and replace the bracketed text with an url you would like displayed in case of error: errorurl=http://localhost/rebooting.htm

End result is a nice page to display when CF is just starting up or has crashed.
