SELECT statement in POM-TestNG classes in java selenium

Question

How to write Select Statement in POM Class. Other TestNG class is calling that POM Class

Below is POM code:

package POM;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.support.FindBy;

import org.openqa.selenium.support.PageFactory;

import org.openqa.selenium.support.ui.Select;

public class LoginCRM {

    @FindBy(id="ctl00_ContentPlaceHolder1_PassiveIdentityProvidersDropDownList")

    private WebElement dropdown;


    @FindBy(id="ctl00_ContentPlaceHolder1_PassiveSignInButton")

    private WebElement sltbtn;


    @FindBy(id="ctl00_ContentPlaceHolder1_UsernameTextBox")

    private WebElement usrname;


    @FindBy(id="ctl00_ContentPlaceHolder1_PasswordTextBox")

    private WebElement password;


    @FindBy(id="ctl00_ContentPlaceHolder1_SubmitButton")

    private WebElement login_btn;


    public LoginCRM(WebDriver driver) {

        PageFactory.initElements(driver, this);

        // TODO Auto-generated constructor stub

    }


    public void login()

    {

        Select sel = new  Select(dropdown);

        sel.selectByVisibleText("HP Internal STS");


        sltbtn.click();

        usrname.sendKeys("r@gmail.com");

        password.sendKeys("@@@@@@@");

        login_btn.click();

    }


}

NullPointerException at select statement of login method 

 @Test

  public void login() {

      LoginCRM log = new LoginCRM(driver);

      log.login();

  }

Below is HTML code

<form id="aspnetForm" action="/adfs/ls/?wa=wsignin1.0&wtrealm=https%3a%2f%2fppmss360.ford.qa.ams.hpmsdynamics.com%2f&wctx=rm%3d1%26id%3dd05e86a7-ae60-4d86-af91-c70fe89fb627%26ru%3dhttps%253a%252f%252fppmss360.ford.qa.ams.hpmsdynamics.com%252fdefault.aspx&wct=2015-12-15T16%3a42%3a34Z&wauth=urn%3aoasis%3anames%3atc%3aSAML%3a1.0%3aam%3apassword" method="post" name="aspnetForm">

Initialize the WebDriver driver and add @BeforeTest method in your TestNG class.

public class WebDriverTest  {       

    WebDriver driver;

    @BeforeTest

     public void setup(){

        driver = new FirefoxDriver();

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        driver.get("file:///C:/Users/dummyUser/Desktop/select_page.html");

    }

@Test

public void testLogin()

{

     LoginCRM log = new LoginCRM(driver);

     log.login();

    }

}
