To use the ColdFusion Debugger that runs in Eclipse, select the Allow Line Debugging option.
Specify the port and the maximum number of simultaneous debugging sessions. Specify the debugger port in the JVM settings of your application server, for example:
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=#portNum#
To stop a currently running debugging session, click Stop Debugging.
To make the changes you specify on this page take effect, restart the ColdFusion server.
