Just wondering if anyone has integrated spago and monogdb.
If so how did you approach this problems?
Any idea wil be much appreciated.
It worked at-last for me. MongoDB with SpagoBI.
All-In-One-SpagoBI-5.1.0_21012015 and installed the mongo-java-driver-3.0.0.jar
Following are the datasource configuration details :
Type: jdbc
URL : server:port/database
User : dbusername
Pasword : dbpasword
Driver: mongo
Details for dataset creation

anyone has JDBC Driver class name and URL format related to this mongodb driver mongo-java-driver-3.12.1.jar found here ?
https://repo1.maven.org/maven2/org/mongodb/mongo-java-driver/3.12.1/
for 2 days i tried all what i found on the web and I get:
No suitable driver found for..
All what i found with clear information is here
http://www.unityjdbc.com/mongojdbc/mongo_jdbc.php
which is not free
finally i used this one. it worked
https://bitbucket.org/dbschema/mongodb-jdbc-driver/src/master/
class: "com.dbschema.MongoJdbcDriver"
URL: "jdbc:mongodb://host:port"
I followed this tutorial to deploy a sample application to Heroku. I just added the below method in MyResource class and returned the result from it instead of "Hello World" from getIt() method. I'm connecting to an atlas free tier cluster:
static String getMessage() {
MongoClient mongoClient = new MongoClient(new MongoClientURI("mongodb://<USER>:<PASSWORD>#cluster0-shard-00-00-2lbue.mongodb.net:27017,cluster0-shard-00-01-2lbue.mongodb.net:27017,cluster0-shard-00-02-2lbue.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin"));
DB database = mongoClient.getDB("mastery");
DBCollection collection = database.getCollection("summary");
DBObject query = new BasicDBObject("_id", new ObjectId("5c563fa2645d6b444c018dcb"));
DBCursor cursor = collection.find(query);
return (String)cursor.one().get("message");
}
This is the driver I'm using:
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver</artifactId>
<version>3.9.1</version>
</dependency>
This is my import:
import com.mongodb.*;
The application works fine from my local system. But I face the below error when I deploy the application to Heroku and hit the service:
INFO: Exception in monitor thread while connecting to server cluster0-shard-00-01-2lbue.mongodb.net:27017

What is this SNI name? I can understand that the drivers are able to pick it from my machine, but not from Heroku machine. But I'm clueless on how to go about solving this! Is there a way to configure Heroku to reveal the SNI name when the driver asks for it? Can we get this value manually from somewhere in Heroku and directly feed it to the MongoDB drivers? Any help is appreciated.
EDIT:
It turned out that the client mentions the SNI name of the server it wishes to connect to as part of TLS security. And there seems to be a way to manually indicate the name in python driver. Is there any way to do this from java? Still puzzled why this is not an issue when running the app locally.
The code I was using to connect to the cluster turned out to be wrong. I followed the directions from the docs and it mentioned this:
To connect to an Atlas M0 (Free Tier) cluster, you must use Java
version 8 or greater and use a Java driver version that supports
MongoDB 3.4.
So I changed the java version to 1.8 in system.properties file:
java.runtime.version=1.8
It was earlier set to 1.7. I was also getting a deprecation warning on one of the methods I had used. So I again followed the docs to use the latest code and it worked like a charm.
The real takeaway here is to refer to the official docs everytime :)
I try to use "./cake bake" to configure my db (mongo) and my models.
When I digit the command on my shell, my output is:
Welcome to CakePHP v2.3.2 Console

What would you like to Bake? (D/M/V/C/P/F/T/Q)

Where are mongoDB's drivers?
Try taking a look at this github repo.
It will allow you to use MongoDB as a datastore for Cake
I am calling the MongoDB aggregate function in my code as :
AggregationOutput output = collection.aggregate( matchUserID, unwindF, matchFUsers,projection);
I have tested my code in my localhost, and it works perfect. When I am using the same in another DB (version 2.2.1), it gives this error :
com.mongodb.CommandResult$CommandFailure: command failed [aggregate]: { "serverUsed" : "<server address>" , "errmsg" : "no such cmd: aggregate" , "bad cmd" : { "aggregate" : .... }
Any clue why ?
Based on other answers I've seen to similar questions, it seems most likely that the server is not actually 2.2.1 as you believe.
How are you checking the server's version number?
From the shell, try this:
use admin
db.runCommand( {buildInfo: 1} )
figured out the error. I was using the 2.9 version on the MongoDB Java driver. When I upgraded it to 2.10, it worked perfectly. Thanks folks :)
I had the same error "no such cmd: aggregate", and I tried new version of mongodb 2.4,2.6 from default debian repositories and always receiving this error.
After that installed mongodb-org-server from mongo repo and it worked
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/
MongoDB shell version: 2.1.0
$near operator works fine. But as I try (in mongodb shell and nodejs):
db.locations.find({loc: {$near:[50,50],$maxDistance:50}})
error: { "$err" : "invalid operator: $maxDistance" }
I tried upgrading mongodb (if you know an easy way to do this I would really really thank you as I had a lot of trouble with trying to shut down the server in order to replace the bin folder...)
Thank you!
upgrading mongodb solved the problem. 10x!
