Why Does My Java Code Throw 'No suitable driver found for 'jdbc:mysql://localhost:3306/mysql''?

"No Suitable Driver Found for 'jdbc:mysql://localhost:3306/mysql'" - Resolving a JDBC Connection Issue

When attempting to connect to a MySQL database using Java, it is possible to encounter the error "java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/mysql". This error indicates that despite having the appropriate driver (e.g., mysql-connector-java-5.1.18-bin.jar) in the build path, the DriverManager is unable to locate a compatible driver.

Cause and Solution

One potential cause of this error is an incorrect JDBC URL. In the provided code:

String url = "'jdbc:mysql://localhost:3306/mysql";

The single quote (') surrounding the URL is causing the error. Simply remove the quote:

String url = "jdbc:mysql://localhost:3306/mysql";

With the corrected URL, the Driver#acceptsURL() method should return true for the loaded driver, allowing the DriverManager to establish a connection successfully.

Additional Notes

• Ensure that the Class#forName() method does not throw a ClassNotFoundException, indicating that the driver class cannot be found in the classpath.
• Confirm that the MySQL server is running and accessible on port 3306.
• Verify that the database credentials (i.e., username and password) are correct.
• Explore additional resources, such as the provided tutorial link, for more detailed guidance on MySQL-JDBC connectivity.
