sendKeys() in Selenium web driver is not working in for Facebook through IE

I am new to Selenium. I just want to send keys to a username text box through internetexplorer using the below code;

Here is the code:

public class IE_Brower {
    public static void main(String[] args) {    
        System.setProperty("", "Driver/IEDriverServer.exe");
        WebDriver driver = new InternetExplorerDriver();

But only facebook page is getting open but value in the text field is not passing. This one is not working.
Please help me.
