    Component.getInstance() always giving the error

    raja garlapati Newbie

      After searching this forum, could not find the exact solution..


      I have a class (say BootStrap ) which has a main method.From this class i am trying to call the DAO class method to do DB activities.


      When i do a Component.getInstance(...,...), its give error .
      I changed to Lifecycle.beginCall()/..endCall() it give me Application context not active.


      Has anyone got any solution for this.
