The Java ES installation program places the uninstaller on your system at the following location:
Solaris OS: /var/sadm/prod/SUNWentsys5
Linux and HP-UX: /var/sadm/prod/sun-entsys5
If the uninstaller is not in this directory, one of the following might have occurred:
Java ES was never installed on this host.
The Java ES uninstaller previously removed all product components and itself from this host.
During uninstallation, if the uninstaller detects that there are no Java ES product components on a host, it uninstalls itself.
During a failed installation, one of the following occurred:
The uninstaller was never installed on the host.
The uninstaller was removed, but some Java ES product components remain on the host.
Suggested Fix. Manually clean up your system as described in Uninstallation Fails, Leaving Behind Files.
