Loading JDBC Driver Class - com.mysql.jdbc.Driver

This section describes how to load the MySQL JDBC driver class, com.mysql.jdbc.Driver, from mysql-connector-java-5.0.7-bin.jar.

MySQL JDBC driver 5.1.38 is a JDBC 4.0 driver. The driver class, com.mysql.jdbc.Driver, needs to be loaded, if you want to use the DriverManager class to create Connection objects. The simplest way to load a driver class is to call the Class.forName() method as shown in the following sample program. Of course, you have to include the mysql-connector-java-5.1.38-bin.jar file in the classpath when you execute this program:

/**
 * MySqlLoadDriver.java
 * Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
public class MySqlLoadDriver {
  public static void main(String [] args) {
    Connection con = null;
    try {

// Load the MySQL JDBC driver
      Class.forName("com.mysql.jdbc.Driver") ;
      System.out.println("MySQL JDBC driver loaded ok.");
 
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());
    }
  }
}

The compilation and execution tests were recorded below. Notice the exception error I got without mysql-connector-java-5.1.38-bin.jar in the classpath:

C:\herong>java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b15)
Java HotSpot(TM) Client VM (build 25.45-b02, mixed mode, sharing)

C:\herong>javac MySqlLoad
Driver.java

C:\herong>java MySqlLoadDriver
Exception: com.mysql.jdbc.Driver

C:\herong>java -cp .;\local\lib\mysql-connector-java-5.1.38-bin.jar 
   MySqlLoadDriver

MySQL JDBC driver loaded ok.
