How to Fix "ClassNotFoundException com.mysql.jdbc.Driver" When Connecting to MySQL Database

When connecting to a MySQL database using Java, you may encounter the "ClassNotFoundException com.mysql.jdbc.Driver" error. This occurs when the MySQL JDBC driver is not properly configured in your Java environment.

One common cause of this error is an incorrectly configured classpath. Despite adding the driver to your classpath, you may still encounter the error due to inconsistencies. To resolve this, follow these steps:

1. Ensure the Driver is in the Classpath: Verify that the MySQL JDBC driver (e.g., mysql-connector-java-5.1.5-bin) is present in the following directories within your Java_Home installation:

• jre/lib/
• jre/lib/ext/
• lib

2. Configure Eclipse for MySQL Driver Usage: If you are using Eclipse for development, the following steps may resolve the issue:

• Right-click your project folder and open Properties.
• Select the Java Build Path tab and navigate to the Libraries tab.
• Click Add External JARs to import the MySQL driver.
• Select the Deployment Assembly tab.
• Click Add..., select Java Build Path Entries, and click Next.
• Select the MySQL driver from the list and click Finish.

This will ensure that Eclipse recognizes the MySQL driver and allows you to connect to the database without the "ClassNotFoundException" error.
