Question

How can I run this mongodb command geonear in Java

 db.runCommand ({ geoNear : “mycollection”, near : [
-121.97679901123047,37.557369232177734],   spherical : true, maxDistance : 50 / 3959 /* to radians */ ,  query : {  $or : [
{“myuserid” : “att”},{“_id”:{$in:
[ObjectId(“4fda8fbbe7e96e2d775595d”)] }}] }    } );

I am trying this in java using Commandresult but getting error.

This is what I did so far and getting Null pointer exception although the command is printing right. I am new to java and database person.

BasicDBObject myCmd = new BasicDBObject(); 
myCmd.append("geoNear", "mycollection"); 
double[] loc = {-121.97679901123047,37.557369232177734}; 
myCmd.append("near", loc); 
myCmd.append("spherical", true); 
myCmd.append("maxDistance", (double)50 / 3959 ); 
System.out.println(myCmd); 
CommandResult myResults = db.command(myCmd); 
System.out.println(myResults.toString());

Thanks in advance.
