To locate the eHour home directory on your filesystem:
eHour standalone: In the folder / directory where eHour is installed is a directory named home. This is the eHour Home directory. Is it not there? Find the exact location in the ehour.vmoptions file, found in the root of the installation folder.
eHour WAR: the eHour home directory is where you unpacked the downloaded WAR distribution, for example /opt/ehour/ehour-1.4.3/
