To use the ColdFusion Debugger that runs in Eclipse or ColdFusion Builder, you must select the Allow Line Debugging option.
Specify the port and the maximum number of simultaneous debugging sessions. You 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 the Stop Debugger Server button.
To make the changes you specify on this page take effect, you must restart the ColdFusion server.
