How to Resolve \"java.lang.ClassNotFoundException: com.mysql.jdbc.Driver\"?

ClassNotFoundException with MySQL JDBC Driver

The error "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver" indicates that the Java runtime cannot find the specified class, which is necessary for establishing a connection to a MySQL database using the JDBC API.

To resolve this issue, make sure the mysql-connector-java driver library is added to the classpath of your Java application. The classpath specifies the locations where the runtime will search for class files.

Add JDBC Driver to Classpath

To add the driver to the classpath, use the following command before running your Java program:

java -cp .;path/to/mysql-connector-java.jar ClientBase

In this command, replace ClientBase with the name of your Java class file, and replace path/to/mysql-connector-java.jar with the actual path to the driver library.

Specific Example

Based on your code and environment, try the following command:

C:\Projects\bin>java -cp .;mysql-connector-java-5.1.25-bin.jar ClientBase

Ensure that the specified driver library file is present in the current working directory or that the path provided is correct. If the classpath is set correctly, the Java runtime should be able to locate and load the MySQL JDBC driver, allowing your program to connect to the database without encountering the ClassNotFoundException.
