Oh I see .. if we get an NPE, that's anyways a bug then. Can you please report this in DSS JIRA [1] (put the log in the console too). Also, do check the MongDB sample we have in the product. That should work. You can compare that and the one you have. The sample is at "$SERVER_ROOT/samples/dbs/mongoDB/MongoDBSampleService.dbs".
