I've created a couple of mapreduce mappers that successfully run. Now, I wanted to use my existing classes (DAOs and Managers) from within these mappers. I developed them for my existing GAE application (that the mapreduce mappers are part of now). I use Guice in my GAE application successfully. So how would I plug mapreduce mappers with Guice DI - so far I have not succeeded with that?
So far I've got this going: I do use Guice Servlet and I have defined serve("/mapreduce/*").with(MyMapReduceServlet.class); in MyServletModule along with my other servlets. mapreduce servlet is defined: @Singleton public class MyMapReduceServlet extends MapReduceServlet { All of them work including mapreduce servlet. But when I launch mapreduce job I get NPE on injected property: @Inject private WineDAO wineDAO; @Inject // not sure this is needed... public DeleteAllMapper() { super(); } -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
