Type 5 DataDirect JDBC驱动程序：找不到合适的驱动程序

Question

我在我的程序中使用Type 5 DataDirect JDBC Drivers，但是当我运行这个程序时，我得到一个例外：

  

java.sql.SQLException：找不到合适的驱动程序   JDBC：DataDirect的：MySQL的：//本地主机：？3306 / jmysql useSSL =假

public class Type5DataDirectDriver {

public static void main(String[] args) {
    Connection con = null;
    // Establish the Connection
    try {
        con = DriverManager.getConnection("jdbc:datadirect:mysql://localhost:3306/jmysql?useSSL=false", "root", "");

        // Verify the Connection
        DatabaseMetaData metaData = con.getMetaData();
        System.out.println("Driver Name: " + metaData.getDriverName());
        System.out.println("Driver Version: " + metaData.getDriverVersion());
        System.out.println("Database Name: " + metaData.getDatabaseProductName());
        System.out.println("Database Version: " + metaData.getDatabaseProductVersion());

    } catch(SQLException ex) {
        ex.printStackTrace();
    }
    finally {
        try {
            if (con != null) {
                con.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
}
