Class GwtServletBase

    java.lang.Object
      javax.servlet.GenericServlet
          javax.servlet.http.HttpServlet
              com.google.gwt.core.server.GwtServletBase

All Implemented Interfaces:

    public class GwtServletBase

extends javax.servlet.http.HttpServlet

Base servlet for GWT server-side code which extracts properties from the request and sets them for this thread.

For now, subclasses should override `init()` and set the locale configuration fields - eventually this will be read from a deploy artifact.
