Tomcat will not respond to port 8080

Tomcat listens on port 8080 but does not respond to HTTP requests. I am running updated Centos 6.2, and Tomcat is installed from the tomcat6 package.

Tomcat is running and listening on port 8080.

# netstat -tlnp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8009 0.0.0.0:* LISTEN 9214/java tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 9214/java tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 981/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1057/master tcp 0 0 127.0.0.1:8005 0.0.0.0:* LISTEN 9214/java # ps aux | grep -i tomcat tomcat 9214 0.0 10.0 164556 51516 ?

But when I connect to port 8080, I get the message "Connection closed by foreign host":

 # telnet localhost 8080 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET / Connection closed by foreign host.

It is important to note that it connects to port 8080, but the connection closes when something is sent in the connection stream:

 # netstat -tnp Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:8080 127.0.0.1:54553 TIME_WAIT -

There are no error messages in the logs:

For peace of mind, I checked the firewall:

 # iptables -L -vn Chain INPUT (policy ACCEPT 6042 packets, 1563K bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 4122 packets, 587K bytes) pkts bytes target prot opt in out source destination

How can I continue troubleshooting !? Thanks!

Maybe you do not have an application deployed on your ROOT?

can you post the contents of your /tomcat/webapps/* ?

let's say you have application.war deployed, so you prefer to do

 GET /application/something

I just tested my working tomcat and when GET / called, it also returns nothing, because the application is not installed there (the default root for tomcat is /tomcat/webapps/ROOT )

Hope I can help.
