I was getting this error:
Embedded browser not available
java.lang.UnsatisfiedLinkError: no swt-mozilla-gtk-3346 or swt-mozilla-gtk in swt.library.path...Apparently the xulrunner package is needed:
sudo apt-get install xulrunner...then close and reopen eclipse. Works like a charm.


Thanks!
I was having the same problem in Ubuntu 8.04 and spent quite some time trying to find a fix. Your suggestion solved my problem--thanks!
THANKS!!!
Thank you so much for this tip! Being a Linux noob I've been struggling for a few days with Ubuntu 8.04 and Eclipse/Aptana and this worked a treat for me. I'm finally able to start playing with Rad Rails on my new Ubuntu notebook!
You've made my day.
