Also, if you go the command line route (method 2 in the doc Matt referenced), note that the correct command parameter doesn't have any spaces in "//ES//LabkeyTomcat", and may be case sensitive. Your pasted text reads "/ES// LabkeyTomcat" (note the space and lower-case 'k')- it should be "//ES//LabKeyTomcat5" instead.

Thanks,
