Did you install from the Ubuntu repository, what package?
When you uninstalled it did you specify --purge?  If not then the
config files will not have been removed.  I think you can use
dpkg --purge <package>
to remove the config files after a package has been removed.  It
certainly should not do any harm.  If that does not help then install
the package and remove it with
sudo apt-get remove --purge <package>

If still no joy then you could try the sledgehammer approach and
search your complete disk for all files containing JAVA_HOME, that
should find it.  It may take some time.
