I just want to add that Julias's answer is correct, but now it's deprecated. You could use new API (Document class is from package org.bson):

MongoDatabase database = client.getDatabase("admin");
Document documentA = database.runCommand(new Document("enablesharding", "test"));
Document documentB = database.runCommand(
        new Document("shardcollection", "testDB.x").append("key", new Document("userId", 1)));

Have you ensured you have authenticated to the db successfully?

Have you tried db.eval(COMMAND_THAT_YOU_WANT_TO_EVAL);

I just found it 

DB db = mongo.getDB("admin");
DBObject cmd = new BasicDBObject();
cmd.put("shardcollection", "testDB.x");
cmd.put("key", new BasicDBObject("userId", 1));
CommandResult result = db.command(cmd);
