MariaDb JDBC Driver
This article will explain what are JDBC drivers, how to download the MariaDb JDBC driver and how to connect to MariaDb using DbSchema Free Database Designer.
What are JDBC Drivers?
JDBC drivers are Java library files with the extension .jar used by all Java applications to connect to the database. Usually, they are provided by the same company which implemented the MariaDb software. DbSchema Tool already includes an MariaDb driver, which is automatically downloaded when you connect to MariaDb.
What is the JDBC URL?
Each JDBC driver is using a specific URL. The URL is a string (text) with a specific format, containing information about the host where the database is running, the port, username, database name, etc. The format is specific to each driver. Any wrong character in the URL may make the database connectivity fail, therefore we recommend installing DbSchema and try to get connected. Then you can find the right URL directly in the DbSchema connection dialog.

The driver files are compressed in a zip file.
for any issues with the driver, you can write to us.
Enable Remote Access on MariaDb Server
By default MariaDb does not allow connecting from another machine as the one where the server is installed. You can enable remote access during installation ( see the next chapter ) or later using the instructions below.- On the server type in the command prompt or terminal mariadb -u root -p <root_password> The mariadb console should start.
- List the databases using show databases
- View the configured grants using select * from db;
- Enable remote access for a user foo using GRANT ALL ON foo.* TO bar@'202.54.10.20' IDENTIFIED BY 'PASSWORD'; Here you have to edit the user ( put your user instead of foo ), the IP of the client machine and the root password.
MariaDb Installation Tips
Install MariaDb from http://www.mysql.com. During installation go for a detailed install, and when you are prompted for the user password check the 'Enable root access from remote machines'.
Enabling this you will be allowed to connect to MariaDb from another computer. Remember the password you set here, it will be requested when connecting to the database as user root.
Connect to MariaDb using DbSchema Free Edition
Installing DbSchema Free edition will help to test the database connectivity and the JDBC driver URL.
When the download finished please follow this steps:
- 1 Select an Alias for your database connection. This will be the name of this specific connection to the database.
- 2 Select 'MariaDb' from the list of DBMS (Database Management Systems).
- 3
The driver for your database will be automatically downloaded for you in the folder
- C:\Users\YourUser\.DbSchema\drivers\MariaDb (Windows) or
- /Users/YourUser/.DbSchema/drivers/MariaDb (Linux and MacOS).
- 4
There are two tabs you can use to connect. 'Compose URL' will ask for the host, port, username, etc., and will create the JDBC URL for you.
The 'Edit URL' will let you directly enter the JDBC URL.
You can use the first tab to connect, and then see the created URL in the second tab.
- 5 If connectivity succeeds, you should get your first DbSchema project and first diagrams.
Connectivity Troubleshooting
If you get problems connecting to the database, please remember :- Press the ping button in the connection dialog to make sure the host and port are reachable.
- Enable Remote connections as they are not always enabled by default. This may require configuration changes.
- Windows Firewall may block the communication. You may need to reconfigure or disable it.
- Check the driver version is compatible with the database software. It may be that DbSchema provided a JDBC driver is not the latest version. Please inform us in this case.
