This happens because the info feature needs to be done using an Ajax
request and by default Ajax requests are limited by all browsers to only
connect to the domain hosting your web application. Any time you access
geoserver on a different domain you will get that error, unless, as you
said, Tomcat is configured to add an "Access-Control-Allow-Origin" header
to allow which clients can connect.
So you have two solutions:
- put your web application and geoserver on the same domain
- enable CORS on the geoserver Tomcat, as you did in your example
configuration (maybe you can limit access only to your webapp host instead
of allowing any client)
