DEVELOPING COLDFUSION 9 APPLICATIONS
Using External Resources
The
method should return within a time-out period that you can configure for each event gateway type in the
start
ColdFusion Administrator. If it does not, the ColdFusion Administrator has a Kill on Startup Timeout option for each
gateway type. If you select the option, and a time-out occurs, the ColdFusion starter thread calls an interrupt on the
gateway thread to try to kill it, and then exits.
Note: If the
method is the listener (for example, in a single-threaded gateway), the method does not return until
start
the gateway stops. Do not set the Kill on Startup Timeout option in the ColdFusion Administrator for such gateways.
If the gateway uses a configuration file, load the configuration from the file. Doing so lets users change the
configuration file and restart the gateway without restarting ColdFusion. Also load the configuration file in the
