mongo-java

Mongo and Java gurus. Our team decided to use full text search API, introduced recently in MongoDB. However, we found some difficulties executing the command using the Java MongoDB driver. here is my code I am using : public BasicDBObject find(String search) { BasicDBObject searchCommand = new BasicDBObject(); searchCommand.put("text", new BasicDBObject().append("search", search)); CommandResult commandResult = db.command(searchCommand); } This is what I get when I print System.out.println(commandResult) { "serverUsed" : "/127.0.0.1:27017" , "errmsg" : "exception: wrong type for field (text) 3

Hi i am trying to learn mongo-java driver.i followed this mongodb documentation . The below is my code public class JMongoDBCDemo { MongoClient mongoClient; DB db; DBCollection coll; public JMongoDBCDemo() { MongoClient mongoClient = new MongoClient( "localhost" , 27017 ); db = mongoClient.getDB( "messenger" ); coll = db.getCollection("users"); DBObject myDoc = coll.findOne(); System.out.println(myDoc); mongoClient.close(); System.out.println("Got a collection..."); } public static void main(String[] args){ JMongoDBCDemo mongoDemo = new JMongoDBCDemo(); } } the below is the output Apr 05, 2015

What is the difference between the cursor.count() and cursor.size() methods of MongoDB's DBCursor ? Parvin Gasimzade From the Javadoc of the MongoDB Java Driver , it says : DBCursor.count() : Counts the number of objects matching the query. This does not take limit/skip into consideration. DBCursor.size() : Counts the number of objects matching the query. This does take limit/skip into consideration. David Chaverri More than an answer I'd like to point out an issue that our team faced "mixing" this two. We had something like this: DBCursor cursor = collection.find(query).limit(batchSize);

I'm trying to use MongoDB's Java driver to make two updates ($set and $push) to a record in the same operation. I'm using code similar to the following: BasicDBObject pushUpdate = new BasicDBObject().append("$push", new BasicDBObject().append("values", dboVital)); BasicDBObject setUpdate = new BasicDBObject().append("$set", new BasicDBObject().append("endTime", time)); BasicDBList combinedUpdate = new BasicDBList(); combinedUpdate.add( pushUpdate); combinedUpdate.add( setUpdate); collection.update( new BasicDBObject().append("_id", pageId), combinedUpdate, true, false); When I combine the $set

I was wondering if there is a way to execute mongo like query directly through Java i.e. we give mongoDB like query as a String to a function in Java driver for mongoDB as a String Object and an DBCursor Object is returned. Something like: import com.mongodb.*; import java.net.UnknownHostException; public class ExecuteQuery { public static void main(String args[]){ try{ Mongo m = new Mongo(); DB db = m.getDB("test"); DBCollection coll = db.getCollection("first"); DBObject doc = new BasicDBObject(); DBCursor cur =coll.executeQuery("db.first.find({"username":"joe"})"); } catch

I am using spring-data-mongodb (1.7.0.RELEASE) with spring-webmvc framework for my web application. I am using basic CRUD functions using mongoRepository but i am not closing mongo connections in my code cause i thought that spring-data-mongodb will close it by itself, But it keeps on opening new connections and not closing them. These too many connections ares crashing my application and i have to restart tomcat again and again (twice a day) to overcome this. Note: Spring Application & mongod is on same server. This is log just after crashing - 2015-07-17T01:31:20.068-0400 I NETWORK [conn3645
