You can curl http://localhost:8080/ and the netstat command above fails? Hmm. That does many any sense at all. – Christopher Schultz
This is very strange issue for me, even after shutting down the server i can access the tomcat page. I cleaned my browser settings, cookies everything even then I am able to accessit.It is also accessiable from other computers. I tried traceroute that gives * * timout message. Curl is also working. – manish
Something is definitely wrong. What is the full URL are you using to access Tomcat's start page? – Christopher Schultz

The tomcat application uses Java so that's why there is no httpd process running:

According to the source posted below the PID is posted in a $CATALINA_PID file which means that all you need to do is read that file with (TomCat version 5 or higher)

 cat $CATALINA_PID

And that should post the PID.

I use to find open ports programs like this:

# lsof -i -n -P | grep LIST | grep 8080
python    10335      xxxxxxxxx    3u  IPv4 10663405      0t0  TCP *:8080 (LISTEN)

The PID is usually defined in the init script. So you should take a look at

/etc/init.d/tomcat

Many init scripts seem to use this command for $PID:

ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'

echo $CATALINA_PID will only return the PID if $CATALINA_PID which is not necassary the case.
