Hi Olaf kock,

first i tried using like below also and same issue i am facing.
   @Reference(unbind = "-")
   protected void setUserService(DLAppService dlAppService) {
       _dlAppService = dlAppService;
   }
   private DLAppService _dlAppService;

i am pass servicecontext like below

ServiceContext serviceContext = ServiceContextFactory.getInstance(DLFileEntry.class.getName(), request);

My first guess with this kind of situation is: How do you get to the serviceContext that you pass? It's a great way to hide some required parameters and if it doesn't pass everything required in the called method, that might lead to NPE along the way.

Secondary (but unrelated to the problem at hand), being in 7.2, you should rather have a @Reference to DLAppLocalService rather than calling through DLAppLocalServiceUtil. This would properly enable the OSGi runtime to manage the dependencies for you rather than hiding them.
