I am trying to connect to database in eclipse to execute a simple login application in which if suppose if login credentials are correct then it will redirect to some other page or else it will tell as incorrect details.

public class DBConnection {
 
	
	static Connection con = null;
	
	public DBConnection()
	{
		
	}
	public static Connection getConnection() throws SQLException
	///public static void main(String[] args) throws ClassNotFoundException, SQLException
	{
		String url = "jdbc:oracle:thin:@localhost:1521:XE";
		String uname = "system";
		String pwd = "password";
			
		try
		{
			//REGISTER DRIVER
			Class.forName("oracle.jdbc.driver.OracleDriver");
			System.out.println("Driver registered successfully..");
			System.out.println();
			//ESTABLISH CONNECTION
			con = DriverManager.getConnection(url, uname, pwd);
			System.out.println("Connection established successfully..");
			System.out.println();	
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
		
		return con;
	}	
	public void closeAll()
	{
		try
		{
			con.close();
		}
		catch (SQLException e)
		{
			e.printStackTrace();
		}
		
	}
}

while running the login pagae ,in console it is saying
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
and

in that

java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)

Please tell me the solution
