Why Am I Getting a Java.lang.ClassNotFoundException: com.mysql.jdbc.Driver?

Java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

This exception signifies that the com.mysql.jdbc.Driver class, essential for establishing a connection to the MySQL database, is not found in the classpath during runtime.

Solution

The following steps will resolve this issue:

1. Verify MySQL Connector/J Inclusion:

   Ensure that the MySQL Connector/J library, a JAR file typically named mysql-connector-java.jar, is included in your project's build path. This library contains the com.mysql.jdbc.Driver class.

   Maven Projects:

   • Add the MySQL Connector/J dependency to your project's pom.xml file:

2. Manual JAR Addition:

   • If you are not using Maven, manually add the mysql-connector-java.jar to your project's classpath:

     • Right-click on the project in your IDE -> "Build Path" -> "Configure Build Path".
     • In the "Libraries" tab, click "Add External JARs" and navigate to the mysql-connector-java.jar file.

3. Class Loading Issue:

   If you have included the JAR file but are still encountering the exception, double-check the class loading mechanism. Ensure that the Class.forName(driver) method is properly loading the com.mysql.jdbc.Driver class.
