javax.servlet.GenericServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

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.
