Converting DBCursor to JSON

[Abhishek kumar]

I am doing following in my application server,

DBCollection collection1 = mongoDB.getCollection("messages");
DBCursor dbCursor1 = collection1.find().limit(5);

I have to send a JSON object to the client from the server, so how can
I convert DBCursor Object to JSON

[Mathias Stearn]

I think you want to iterate the cursor and convert each returned object to JSON then put them into an array.

How can I convert DBCursor Object to JSON, is there any direct method/
function
also
is there any single function which directly convert DBCursor to JSON

What I am trying to achieve is, I dont want extra overhead at the
server side, I just want to retrieve the results from the mongodb
database and send to client as JSON. As mongodb stores in form of
BSON, so can there be any way, so that I dont require extra overhead
at the server side to convert to JSON and then send to the client

You should be able to call com.mongodb.util.JSON.serialize(...) and
pass in the cursor. It will return a json string which is an array and
includes all the docs in that json string.

BSON != JSON, so there will have to be a bit of decoding/encoding
going on in java.
