if you go into your project properties, you select run/debug settings in the left pane, on the right pane select the project and then go to edit.
from there you can set the launch path,
it would be something like
http://localhost/MyProj-debug/MyProj.html for browser
c:\MyWorkSpace\MyProj\bin-debug\MyProj.swf to launch in flashplayer
Worked, thank you.
