Sun GlassFish Enterprise Server 2.1 Release Notes

Description

If the Enterprise Server productregistry file contains shared component configurations, an Enterprise Server uninstallation procedure does not update the productregistry file correctly, and you will not be able to use silent mode in a subsequent installation unless the productregistry file is renamed or removed. Leaving the shared components entries in the productregistry file intact is by design, but it leads to confusion with subsequent silent installs.
