That is correct. I guess you restarted Glassfish afterwards and it is running before you go the the Eclipse debugging session.

This is the configuration of the Java program to be debugged (i.e. the server).
But the Eclipse launch configuration is the client which wants connect to port 9009.
So you simply tell Eclipse the port where it finds Glassfish:
1. Select Debug configuration for "Remote Java application"
2. Fill in host (localhost) and port (9009)
and you are done! Press "Debug" and Eclipse will connect via port 9009 to the running Glassfish instance.
With regard to Ludos answers: He presumes that you have the Glassfish plugin for Eclipse installed, which is a good idea and may support you in managing the server completely from Eclipse.
But the above launch configuration is independent of any GF plugin installed.
