Can't access tomcat web page from lan - linux

Question

I installed a tomcat7 server on a ubuntu 12.04 box. I simply used "apt-get install tomcat7". I did not install apache2. I can access the default page from localhost:8080, 127.0.0.1:8080, and 192.168.1.201:8080, where the latter is the IP address from my LAN. my end goal is to be able to access the web server from outside the LAN with port forwarding. For now, however, I can't even access it inside the LAN.
Problem:
I can't access the web page from any other computer (windows 7, iPad) on the same LAN! I
get the "connection has timed out" error from the browser.
Question: Can I run tomcat on it's own without installing Apache2 first? This is the current setup and I can access pages hosted on tomcat on the same server, but not over the LAN.
Other information:
I can ping the ubuntu computer from other machines
The ubuntu firewall is disabled (checked via the firewall GUI interface).
I also tried "sudo ufw disable"
I tried: "sudo service iptables stop" and got the message: "iptables: unrecognized service"
I also tried disabling the appArmor firewall:
sudo /etc/init.d/apparmor stop
sudo /etc/init.d/apparmor teardown
sudo update-rc.d -f apparmor remove
I set the router firewall policy to minimum: inbound: accept all; outbount: accept all.
All computers (including ubuntu server) are connected to LAN via wireless
The ubuntu server IP address is static, not DHCP
I checked the SELinux folder and it's empty. I removed it.
Thank you for your help,
Omar
EDIT:
I can connect from within the LAN using ssh (I installed OpenSSH on ubuntu).

ANSWER:
I found the solution to this problem. It turned out there was a firewall active that was blocking the port. The firewall is called "firestarter". Not sure how this was installed, but it can be downloaded from the ubuntu software center. The default inboud policy blocks all ports except for SSH (22). I opened port 8080 and everything worked just fine. The other firewalls (ufw and SELinux) were disabled.
Thank you all again for your help.

Answer 2

First of all make sure all of the IP addresses are topologically correct, then ping to the your apache server system, If all this succeeds your network is fine.
Now the question are you using the Ubuntu Server edition? if this is the case i believe you can setup apache out of the box.
In case of the Desktop edition you could install it using command line or just install something like XAMP from apache friends.
Make sure your apache Server is started
If you do not already have Apache installed, you can do so now by issuing the following commands:
sudo apt-get update
sudo apt-get install apache2
This is all that is necessary to have a working web server.

I think, "apt-get install tomcat7" doesnt works in Ubuntu. You have to manually download the TAR file & then you can install it with the scripts. Please check whether it is properly installed or not. it should show a Apache Tomcat Homepage # localhost:8080
Also if it is installed properly, check whether it is running on the port 8080, or any other port.
If everything is fine, then disable the firewall of the Server, where you have installed the Tomcat. check for the server IP.
Now from other machine, access that server using http://server_ip:port
This should work fine. No issues should be there.
The other thing, you have metioned in your question, UBUNTU BOX. May be this issue arises due to UBUNTU BOX. If possible, make a clean install of Ubuntu.
