  • java.lang.Object
    • javax.servlet.GenericServlet
      • javax.servlet.http.HttpServlet
        • com.ibm.tivoli.maximo.report.birt.bridge.launcher.BridgeServlet
  • All Implemented Interfaces:

    public class BridgeServlet
extends javax.servlet.http.HttpServlet
    The BridgeServlet provides a means to bridge the servlet and OSGi runtimes. This class has 3 main repsonsibilities: 1) Control the lifecycle of the associated FrameworkLauncher in line with its own lifecycle 2) Provide a servlet "hook" that allows all servlet requests to be delegated to the registered servlet 3) Provide means to manually control the framework lifecycle

        public void init()
          throws javax.servlet.ServletException

      • registerServletDelegate

        public static void registerServletDelegate(javax.servlet.http.HttpServlet servletDelegate)
        registerServletDelegate is the hook method called from inside the OSGi runtime to register a servlet for which all future servlet calls will be delegated. If not null and no delegate is currently registered, init(ServletConfig) will be called on the servletDelegate before returning.
        Parameters:
        servletDelegate - - the servlet to register for delegation

      • unregisterServletDelegate

        public static void unregisterServletDelegate(javax.servlet.http.HttpServlet servletDelegate)
        unregisterServletDelegate is the hook method called from inside the OSGi runtime to unregister a delegate. If the servletDelegate matches the current registered delegate destroy() is called on the servletDelegate. destroy() will not be called until the delegate is finished servicing any previous requests.
        Parameters:
        servletDelegate - - the servlet to unregister
