Not all GlassFish Server directories are automatically removed by the uninstallation program. Some directories and files remain after uninstalling.
Examine the remaining directories and remove any files or directories that you do not want, including hidden directories prefixed with a dot. It is safe to remove uninstallation and installation log files after you have examined them.
For information related to uninstallation, see Chapter 2, Uninstalling Oracle GlassFish Server 3.0.1, in Oracle GlassFish Server 3.0.1 Installation Guide.
