The program works in IDE but not on the export jar

Issue

I have to connect my database with java. The program work fine in my Eclipse IDE but when i export in jar file . I get this error: connection failure: No suitable driver found for jdbc:sqlserver://myServer:1433;databaseName=mydb

This is my code

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

import javax.swing.JOptionPane;

public class DriverManagerSql {

    public static void main(String[] args) {
        Connection connection = null;
        String dbUrl = "jdbc:sqlserver://myServer:1433;databaseName=mydb";
        String username = "sa";
        String password = "12345";
        try {
            connection = DriverManager.getConnection(dbUrl, username, password);
            if (connection != null) {
                 JOptionPane.showMessageDialog(null, "good connection");
            }
        } catch (SQLException e) {
            JOptionPane.showMessageDialog(null, "connection failure:" + e.getMessage());
        } finally {
            try {
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                System.err.println("Error while closing the connection: " + e.getMessage());
            }
        }

    }

}

Solution

I resolved the problem by reinstalling JDK on my PC.
