Anyone have an idea to share running multiple tomcats on the same machine with the same port 8080
One way would be to create a single web server on the 8080 server (like Apache, but your choice) that forwards requests based on the URL to the appropriate Tomcat instance running on a different port, like 8081 or 8082.
AFAIK, you cannot run two different webservers on the same port.
You cannot do this. Leave tomcat alone, it won't work with any combination of servers. Explain your requirements better
Any instance of the application can listen on the same port, since the server supports deleting ports! Any request for this adr: port will be shared among these different instances.
