J Connector: Download, Configure, and Develop with MySQL Connector/J 8.0

What is J Connector and Why You Need It

If you are a Java developer who works with MySQL databases, you might have heard of J Connector. But what is it exactly and why do you need it?

download j connector

J Connector, also known as MySQL Connector/J, is the official JDBC driver for MySQL. JDBC stands for Java Database Connectivity, which is a standard API for connecting Java applications to various types of databases. J Connector allows you to communicate with MySQL servers using SQL statements or the new X DevAPI, which is a modern, schema-less CRUD API for working with JSON documents.

Some of the features and benefits of using J Connector are:

  • It is compatible with all MySQL versions starting with MySQL 5.6, including MySQL Server 8.0 and 5.7.

  • It supports both JDBC 4.2 and X DevAPI specifications, giving you more flexibility and options for developing your applications.

  • It is free for usage under the terms of the specified licensing and it runs on any operating system that is able to run a Java Virtual Machine.

  • It offers advanced features such as connection pooling, load balancing, failover, encryption, compression, schema validation, logging, and more.

In this article, we will show you how to download, install, and use J Connector with your Java applications. We will also compare it to some other JDBC drivers for MySQL and answer some frequently asked questions about it.

How to Download J Connector from MySQL Website

The easiest way to download J Connector is from the official MySQL website. Here are the steps to follow:

  • Log into using Oracle SSO.

  • Go to .

  • Select your operating system and choose the version of J Connector that you want to download. The recommended version is 8.0.32.

  • Click on the blue "Download" button and save the file to your desired location.

You can also download J Connector from other sources, such as Maven Central Repository or GitHub, but make sure that you verify the authenticity and integrity of the files before using them.

How to Install J Connector on Your System

Once you have downloaded J Connector, you need to install it on your system. The installation process depends on your operating system and how you want to use J Connector. Here are some common scenarios:

If you want to use J Connector with a standalone Java application

You can simply copy the JAR file of J Connector (for example, mysql-connector-java-8.0.32.jar) to your classpath or add it as a library dependency in your IDE or build tool.

If you want to use J Connector with a web application server or a container

You need to copy the JAR file of J Connector to the appropriate location in your server or container. For example, if you are using Tomcat, you can copy it to the lib directory under the Tomcat installation folder. For more details, see .

If you want to use J Connector with a Java EE application server or a framework

You need to configure J Connector as a data source in your server or framework. For example, if you are using Spring, you can use Spring Boot Starter JDBC or Spring Data JDBC to configure J Connector as a data source bean. For more details, see .

How to Use J Connector with Java Applications

After you have installed J Connector on your system, you can use it with your Java applications to connect to MySQL databases and perform various operations. You can use either JDBC or X DevAPI to interact with MySQL servers using J Connector.

Using J Connector with JDBC

JDBC is the traditional way of using J Connector with Java applications. It allows you to execute SQL statements and retrieve results using Java objects. Here is an example of how to use J Connector with JDBC:

// Load the driver class Class.forName("com.mysql.cj.jdbc.Driver"); // Establish a connection to the database Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "password"); // Create a statement object Statement stmt = conn.createStatement(); // Execute a query and get a result set ResultSet rs = stmt.executeQuery("SELECT * FROM users"); // Loop through the result set and print the data while ( System.out.println(rs.getInt("id") + " " + rs.getString("name") + " " + rs.getString("email")); // Close the resources rs.close(); stmt.close(); conn.close();

For more details, see .

Using J Connector with X DevAPI

X DevAPI is the new way of using J Connector with Java applications. It allows you to work with JSON documents and collections using a fluent and intuitive API. Here is an example of how to use J Connector with X DevAPI:

// Create a session object Session session = new SessionFactory().getSession("mysqlx://root:password@localhost:33060/test"); // Get a schema object Schema schema = session.getSchema("test"); // Get a collection object Collection coll = schema.getCollection("users"); // Insert a document into the collection coll.add("\"name\": \"Alice\", \"email\": \"\"").execute(); // Find a document from the collection DocResult docs = coll.find("name like :name").bind("name", "Alice").execute(); // Print the document data while (docs.hasNext()) DbDoc doc =; System.out.println(doc.get("_id") + " " + doc.get("name") + " " + doc.get("email")); // Close the session session.close();

For more details, see .

Alternatives and Comparisons to J Connector

J Connector is not the only JDBC driver for MySQL. There are some other options that you can consider, such as:

  • : This is the official JDBC driver for MariaDB, which is a fork of MySQL. It is compatible with MySQL servers and offers some additional features, such as support for MariaDB-specific extensions and data types.

  • : This is an open-source JDBC driver for MySQL that is based on the original MySQL Connector/J code. It is lightweight and simple, but it does not support some features, such as X DevAPI, SSL, or connection pooling.

  • : This is an open-source JDBC driver for Microsoft SQL Server and Sybase databases. It can also connect to MySQL servers using a TDS protocol bridge, but it may not support some features, such as stored procedures, prepared statements, or transactions.

To compare these drivers to J Connector, you can use some criteria, such as:


J ConnectorGPLv2 or CommercialAll MySQL versions from 5.6 onwardsJDBC 4.2, X DevAPI, SSL, Connection Pooling, Load Balancing, Failover, etc.High

MariaDB Connector/JLGPLv2.1 or CommercialAll MySQL versions from 5.1 onwardsJDBC 4.2, SSL, Connection Pooling, Load Balancing, Failover, MariaDB Extensions, etc.High

Drizzle JDBCLGPLv3 or Apache LicenseAll MySQL versions from 4.1 onwardsJDBC 4.0, SSL, etc.Medium

jTDSLGPLv2.1 or BSD LicenseMySQL versions from 4.0 to 5.1 using TDS protocol bridgeJDBC 3.0, SSL, etc.Low

As you can see, J Connector is the most comprehensive and reliable JDBC driver for MySQL, as it supports the latest features and standards and offers the best performance and security. However, depending on your specific needs and preferences, you may choose to use another driver that suits your requirements.
