Fundamentally nothing has really changed. AJAX and therefore GWT is primarily a client side technology. What you've described are primarily server side. The major difference between an AJAX based web client and a traditional web client (like ASP, ASP.Net or even JSP) is how the information is pushed up to the server. In GWT-RPC, a client side proxy of a server based Java class is instantiated. When this is compiled into Javascript on the client this is "translated" into a client side XMLHTTP request, posting data to a specific server side servlet. If your server is not Java, then your options move to GWT Form Posting, which will end up looking very similar to the old ASP/ JSP form post servers, or there is a GWT-JSON method that allows submission of data to many brand servers using Javascript Object Notation.
So to answer your question shorter: it depends on the technology stack that your server has. Good luck!
