    Component.getInstance and 64bit java

    Pavel Stánek Newbie

      Hello,

      I have custom servlet, when I call

      209: PictureShowAction psa = (PictureShowAction) Component.getInstance(PictureShowAction.class);
      210: Picture mi = psa.getImage(idLong);
      


      in this servlet, I get sometimes null value into psa variable.

      On my developer notebook (32bit java, tomcat 6.0.10) all works fine, on server (64bit java, tomcat 6.0.13) I get sometimes NullPointerException.

      Exception:
      java.lang.NullPointerException
