Tomcat won't respond on port 8080
centos, java, linux, tomcat
Solution
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.
Problem
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. ``` # 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 ?

Thanks!
