Can not run Openfire on Debian or on Ubuntu(Google Cloud VM)

I am using Google Cloud VM running Debian OS. I installed openfire following these steps:

• $ sudo apt-get install default-jre (also separately installed openjdk)
• $ sudo apt-get install
• $ wget -O openfire.deb http://www.igniterealtime.org/downloadServlet?filename=openfire/openfire_3.10.2_ all.deb
• $ sudo dpkg --install openfire.deb
• $ sudo /etc/init.d/openfire start

After the last command: 'start' it says:

best java alternative in: /usr/lib/jvm/java-6-openjdk-amd64/jre

Starting openfire: openfire.

And When I run http://myhost:9090 on my browser, it doesn't open setup window, it doesn't work at all. So please help me to make it work.
