Package com.google.gwt.core.server

Class GwtServletBase

  • 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.
