  • What you are asking for doesn't really make sense, and isn't directly possible.

    GWT is a client-side library - it compiles to Javascript and runs like JQuery would do, entirely in the browser. Using RPC or RequestFactory you can talk to existing Java classes on the server using their provided servlets, or you can use any kind of AJAX to get data from the server.

    It isn't possible to make connections directly to the server from the browser. Instead, your client should open a connection to the server, and let the server make the connection. If using Java on the server, look for tutorials to connect to a in memory db from Java.
