Dear Yewint,

Ubuntu? Is this a real tomcat, or that broken Debian package?

Try downloading a normal Tomcat and see if that fixes the problem. If it does, talk to the packager about what he changed to make this not work for you.

I don't know anything about a specific Ubuntu Tomcat packaging, but Tomcat won't shut down as long as any of the threads of any of the applications under Tomcat are still running.

While you should never spawn threads in servlets*, JSPs, or EJBs (or in code called by them), it is sometimes useful to spawn offline processor threads - *which can be safely in in a servlet's init() method - and otherwise use thread-spawning facilities such as Quartz.

If you do spawn threads in a webapp, you must terminate them when a Tomcat shutdown is initiated or Tomcat will hang.

The problem with accessing apps from other machines is probably just the standard firewall problem.

You might have a port conflict on your shutdown port.
Look in server.xml to see which port Tomcat is using for this.
Here it is in a copy of Tomcat downloaded from the Apache site:

Once you know which port it's trying to use.
Run netstat to see if something else is using this port.
If so, change the port number in server.xml to something that's not being used.

Then startup tomcat and see if you can shut it down.

i found no port conflict. when i run " netstat -anlpt|grep :80" , 8080 is not opening. I use 8080 for connector port and 8089 for shutdown. here is the line from server.xml for defining shutdown port

the following is the logs from $CATALINA_HOME/logs/catalina.out

Look on lines 24 and 25.

The bind exception is not for port 80 or 8080

It's 8089
