FusionDebug Technote - FDS-104

In order to run FusionDebug 3 (or higher) against Railo on the Caucho Resin platform, Resin must be configured to allow debugging connections.

This is configured in RESIN_HOME\conf\resin.conf

• Ensure Resin is halted.
• Locate the file mentioned above and edit it.
• Locate the block of jvm-arg configuration items and add

<jvm-arg>-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000</jvm-arg>

to the list.

• Restart Resin.

If debugging has been configured, you will see:

Listening for transport dt_socket at address: 8000

as the first line of the Resin startup.
