Failed to reach an application on JBOSS AS running on a rem

[xijia_chen]

Greeting....

I install JBOSS AS 4.0.2 on a linux env, deployed an ear (war +jar) to the application server and start the JBOSS AS successfully( without seeing any error) by running sh ./run.sh.

But, when I tried to reach the application (on a remote server machine running linux and it is not in the same network as my laptop is) through
http://[the server's ip address]:8080/index from my laptop,
I did not see anything happen on the server end, and I did not get anything on the web browser on my laptop.

I have not setup my domain name yet.
The remote server machine do have a valid public IP address and available through internet. I can ping it successfully.

I can run the appliciaotn with JBOSS AS 4.0.2 stored on my laptop, and access it through http://localhost:8080/index without any problem.

Would some expert tell me what cause the problem?
I am wondering I may need configure some file, but do not which one(s), I tried some ones, did not work.

Thank you in advance!

Frank

What are your firewall settings? I ran into the same problem until I configured iptables to open port 8080.

Peter,

Thank you for the quick response.
the iptables is not active (when I run chkconfig --list iptables, I see all are offs) in my case I think.
do you still think it is caused by iptables?

Could you tell me how did you setup the iptables,
did you update etc/sysconfig/iptables directly?
after you added the port 8080, do you need restart the linux system to make the new iptables rule effective?

Thank you!

Here are the lines I added to /etc/sysconfig/iptables for JBoss:

# Ports used by JBoss
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

Then I restarted iptables: /etc/init.d/iptables restart

Peter,

It works now after I did some other twists in my server/network configuration(e.g.. 8080 was used for some other purpose, I have to use another port for jboss as, etc.).

The direction you pointed at is exactly right.

Thanks a lot for your help and quick response!

Best Regards,

Frank
