I tried to add a Glassfish Server to NetBeans. It needs the actual path where the server is siting in. I used "apt-get" to install my glassfish instance. I have totally no ideas where the server installed. I found that is in "/usr/share/glassfishv2". If you have the same problem, that is very easy to find the server path. Just these two steps:
1. sudo updatedb
- Update the database with the file paths.
2. locate asenv.conf
- That is a config file under {glassfish server}/Config.
