I have been looking forward to this extra bit of functionality to the Zimbra line up. I had a couple of hours today to play and just off the top on the first attempt, the desktop software installs on Windows and Ubuntu 6.10 (well nearly- hangs when starting service) but no connection can be made to the localhost/port using the required URL. This is, I strongly suspect, because the zdesktop service reports status as not running and fails to start ;-)
Other than the need for certain software ie Java from the install are there any 'not-requirements' such as dont have another webserver installed or any other Java install etc.
Not much in the logs for install, just in the terminal I see:
log4j:WARN No appenders could be found for logger (org.apache.commons.httpclient.HttpClient).
log4j:WARN Please initialize the log4j system properly.
Error: invoke Connection refused, server: localhost
To save a bit of time on my part, any hints would be welcome!
