Normally Apache Tomcat comes with the default index.html file. So if you go to http://localhost:8080/index.html with your web browser it will serve you the index.html file with HTTP status 200.
At the terminal, the HTTP status can be obtained with the following command.
curl -sI http://localhost:8080/index.html|head -1|awk '{print $2}'
This works if the Apache Tomcat is serving a file. What if it is a load balancer that listens to port 8080 but does not serve any files. To test if it is working and listening to port 8080. Use the following command.
nc -z localhost 8080 2>&1|grep succeeded|wc -l
If successful, the result is 1. If unsuccessful, the result is 0.
