Yes, you can use iis as an 80-port server, and then add an extension of tomcat to iis to parse jsp.

Of course, tomcat must remove the occupation of port 80.

This is equivalent to configuring iis as a universal host for web servers that support ASP.NET and jsp. I suggest you search, iis supports articles such as jsp to configure iis.

This configuration does not require a port number.

The specific configuration can refer to the reference materials I provided.
