MongoClientURI uri = new MongoClientURI(
"mongodb+srv://<username>:<password>cluster0-kjxf3.mongodb.net/test?retryWrites=true&w=majority");
MongoClient mongoClient = new MongoClient(uri);
Returns Response message:Exception: java.lang.IllegalArgumentException: uri needs to start with mongodb://. Above URL example comes from MongoDB Atlas manual, deleting +srv causes:
java.net.UnknownHostException: mongodb.net: Name or service not known
As per Driver Examples documentation section
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. For complete documentation on compatibility between the Java driver and MongoDB, see the MongoDB compatibility matrix.
So make sure to download MongoDB Java Driver version 3.4 or higher and drop it to JMeter Classpath. You will also need to remove all previous versions of the MongoDB Driver to avoid Jar Hell. JMeter restart will be required to pick up the new .jar and unload old ones (if any)
You may also find MongoDB Performance Testing with JMeter article useful.

Do you know a Scala driver to MongoDB, which is also compatible to Amazon DocumentDB? In theory they all should be compatible, I am interested what works in practice. In particular, I plan to use reactivemongo.
https://mongodb.github.io/mongo-scala-driver/ is compatible with Amazon DocumentDB.
Main point is to properly use the RDS certificate (cannot be tested locally w/o tunnel), as indicated in the documentation.
mongodb.uri = "mongodb://${USER}:${PASSWORD}#${DOCDB_CLUSTER}${AWS_REGION}.docdb.amazonaws.com:27017/${DB_NAME}?ssl=true&keyStore=file:///path/on/local/fs/to/rds-ca-2015-root.jks&keyStorePassword=${KEYSTORE_PASS}&keyStoreType=JKS"
I'm using the MongoDB Java Driver. I have many requests and it is limited by this driver, requesting 1 at a time.
I want to perform async requests to MongoDB. Hence there is a need to change my program to either an MongoDB Async Java Driver OR use a MongoDB NodeJS Driver.
Which do you recommend? My app deals with a lot of JSON objects. I am fluent in both Java and Javascript :)
Thank you in advance!
I am looking for someone that can explain me in simple terms with written instructions how to create a JDBC in PostgreSQL (I am losing my mind with this). I found other answers in this page and others but I couldn't follow them.
I am no programmer, so I didn't undertand any of the instructions of how to do it in webpages and forums -the method mentioned was configuring the classpath environment variable in the command prompt but I got stuck in the command prompt, I think I have to configure the Java console or something.
I am learning some data mining and I wish to connect to some databases in order to practice. I suppose that for someone knowledgeable in this area this should be an easy job.
I prefer to install a driver in postgresql and not using a bridge.
Thanks a lot!
The phrase “how to create a JDBC” makes no sense.
You need to learn some basics first. Be clear on what JDBC is (a standard for connecting or mediating between a database and a Java app), what a JDBC driver is (a particular implementation of JDBC for a specific database.
There are four types of JDBC drivers, the Type 4 (pure Java) being most common in my experience.
For any particular database, you may find there are zero, one or more drivers implemented and available. Some are free-of-cost and open-source, some are not. For example, in Postgres there are two open source drivers, the classic one and a newer rewrite-from-scratch one, as well as some commercial products.
A JDBC driver is only useful when trying to connect a Java app to your database. That may be your own app you are writing, or a finished app you obtained such as a database-administration tool.
You must have a Java implementation installed on your computer, such as one from Oracle or from the OpenJDK project, or from another vendor such as Azul (Zing & Zulu).
You need to learn about the Java Classpath, the list of all the folders where the JVM will be looking for Java classes and JAR files. Read the Oracle Tutorial. The easiest way to go is to drop your JDBC driver JAR into an already existing folder on the Classpath, so you do not need to twiddle with setting the Classpath. For example, on a Mac you could drop your driver into /Library/Java/Extensions.
The JDBC driver sits between the database engine and the Java app. You do not install the JDBC driver into the database engine, such as your Questions mentioned, “install a driver in postgresql”.
[Postgres] ↔ [JDBC driver] ↔ [JVM] ↔ [Java app]
When I try to use MongoDB driver in my play framework application's application.conf as
db.default.driver=com.mongodb
I am getting Driver not found error. I have configured dependency in Build.scala for MongoDB driver.
I am using official Java driver for MongoDB mongo-java-driver v 2.11.1. I want this driver to be used with Ebean.
What is the correct class name to be used in the db.default.driver to get this working?
EBean doesn't support MongoDB, it only works with relational databases as it is a JPA-compliant driver.
Here you have an example using Java and MongoDB which may help you to bootstrap your project
Click [here](https://github.com/ReactiveMongo/Play-ReactiveMongo"ReactiveMongo Support to Play! Framework 2.3")!
This is a plugin for Play 2.3, enabling support for ReactiveMongo - reactive, asynchronous and non-blocking Scala driver for MongoDB.
ReactiveMongo is a scala driver that provides fully non-blocking and asynchronous I/O operations.

Recently I discovered the power of noSQL database MongoDB. After a lot of trial and error I was able to install it on my pc along with wampserver. Its running smoothly. Now the question I would like to ask is, that if I want to integrate the MongoDB service provided by Mongolab on my shared hosting plan, is there any class available that helps me connect to the database? Like a php class version of the driver for php and mongodb. As it is not possible to install the driver on my hosting, because of no root access. So is there a raw class available as an alternative to the driver dll?
If you can't install the driver, then the REST interface provided by MongoLab is your best bet - any language that can send/receive a HTTP request can use REST:
