My application is served by CouchDB (as what they call a "couchapp") and also communicates back to the CouchDB server for back-end persistence and certain queries. You could easily serve a GWT application with a Node.js server too. You can serve as many applications as you want from a single port as long as you have unique URLs for everything the server provides.
Good luck and welcome to GWT. smoyer -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
