I get a following error - java.net.BindException. I learned that machine had another process(none other than tomcat) running at that port.
I have done the following with out any success.
1. I could not get th PID(using command 'netstat -a -o -n' ) for old instance of tomcat, to terminate that process using command'killtask /f /pid XXXX' .
2. I re-installed tomcat, still same results
Assuming you have no other server already running on port 80, you'll find it convenient to configure Tomcat to run on the default HTTP port (80) instead of the out-of-the-box port of 8080. Making this change lets you use URLs of the form http://localhost/blah instead of http://localhost:8080/blah. Note that you need admin privileges to make this change on Unix/Linux. Also note that some versions of Windows automatically start IIS on port 80. So, if you use XP and want to use port 80 for Tomcat, you may need to disable IIS (see the Administrative Tools section of the Control Panel).
To change the port, edit install_dir/conf/server.xml and change the port attribute of the Connector element from 8080 to 80, yielding a result similar to that below.
<Connector port="80" protocol="HTTP/1.1" ... >
try this... let jboss take 8080 if that is also running parellaly ....
