[SOLVED] Openhab cannot run on ubuntu 14.04

I used the following link to install openhab:

sami@sami:~$ sudo /etc/init.d/openhab start
[sudo] password for sami:

Starting openHAB server openhab [ OK ]
sami@sami~$ sudo  /etc/init.d/openhab status
openhab is running

How can i run Openhab?
When i run the above commands, Openhab did not work.

Please, guide me.

That is an old and out of date doc.

Thank you.
