Register the Driver

Register the Driver

There are two ways to register the JDBC driver,

1. Using the forName() method.
2. Using the registerDriver() method.

forName() method

• The forName() method is exists in java.lang.Class class.
• Its a static method, so we need to call this method by using class name
• This method will helpful to register the jdbc driver
• This method loads the Driver class dynamically.

Syntax

public static void forName(String className)throws ClassNotFoundException

Example

Class.forName("oracle.jdbc.driver.OracleDriver");

-------------------------------------------------------------------------------------

Program         :       Demo to register the database

Program name  :      DBRegister1.java

Output             :         

 Driver is Registered successfully

class DBRegister1

{

public static void main(String args[])throws ClassNotFoundException

{

Class.forName("oracle.jdbc.driver.OracleDriver");

System.out.println("Driver is Registered successfully");

}

}

Note:

To compile above java program we have to set the class path to ojdbc14.jar, so, keep this jar in corresponding directory then set the class path.

Set class path:

• C:\Nireekshan\JDBC>set classpath=ojdbc14.jar;.;

Compile      :          javac DBRegister1.java

Run            :          java DBRegister1

Output        :         

Driver is Registered successfully

-------------------------------------------------------------------------------------

registerDriver() method

• The registerDriver() method is exists in java.sql.DriverManager class.
• Its a static method, so we need to call this method by using class name.
• This method will helpful to register the jdbc driver

Syntax

             public static void registerDriver(Driver driver)

• Very first step we need to create object to Driver to load a JDBC driver.
• The created driver object we need to pass as parameter to registerDriver() method.
• In second step we need to call registerDriver() method.

Syntax 

                    Driver driver = new <DriverName>();

Example

               DriverManager.registerDriver(driver);

-------------------------------------------------------------------------------------

Program         :       Demo to register the database

Program name  :      DBRegister2.java

Output             :         

 Driver is Registered successfully

import java.sql.*;

class DBRegister2

{

public static void main(String args[])throws SQLException

{

Driver d=new oracle.jdbc.driver.OracleDriver();

DriverManager.registerDriver(d);

System.out.println("Driver is Registered successfully");

}

}

Note:

To compile above java program we have to set the class path to ojdbc14.jar, so, keep this jar in corresponding directory then set the class path.

Set class path:

• C:\Nireekshan\JDBC>set classpath=ojdbc14.jar;.;

Compile      :          javac DBRegister2.java

Run            :          java DBRegister2

Output        :         

Driver is Registered successfully
