[news.eclipse.platform] Re: [MAC OS X] Unable to open external editor

[David Rocks <rocks@xxxxxxxx>]

   The runtime(exec) method used to call pgms from within eclipse 
doesn't use the 'launch' interface and therefore can't call the 
application bundle (..app) under OS X. You have to provide the full path 
to the executable. In your case /Applications/jEdit 
4.2/jEdit.app/Contents/MacOS/JavaApplicationStub.
	This has consequences for some applications if they are already running 
on your desktop. It will always try to start a new instance, which some 
apps will refuse to do if they are already running. It may also cause 
problems if you are passing parameters. Some apps, like IE, expect file 
paths in 'classic' style: Volume:Path, which eclipse doesn't seem to 
support. Good luck.
