Please suggest.

1. Take a look into mongodb quick start

2. Take a look into mongodb java tutorial. Here you can find how to connect/query/update mongodb.

3. To retrieve data from mongodb via javascript create some service layer (it can be simple rest api) that will return data in json format for example.

Javascript way of printing output of MongoDB query to a file

1] create a javascript file

test.js

cursor = db.printShardingStatus();
while(cursor.hasNext()){
  printjson(cursor.next());
}

2] run

mongo admin --quiet test.js > output.txt
