Tomcat won't respond on port 8080

Question

Tomcat is listening on port 8080, but it do not respond correctly to HTTP requests. I'm running an updated Centos 6.2, and Tomcat is installed from the package tomcat6.

Tomcat is running and listening on port 8080.

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

# 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's important to note that it do connect to port 8080, but the connection is closed when anything is sent on the connection stream:

# netstat -tnp

The logs show no error messages:

For the 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 do any further troubleshooting!? Thanks!

Answer 1

It could be that you don't have any application deployed on your ROOT?

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

say you have application.war deployed so you'd rather do

GET /application/something

I just tested on my working tomcat and when calling GET / it also returns nothing because there is no application deployed over there (default for root in tomcat is /tomcat/webapps/ROOT)

Hope I could help.
