selenium cannot run on eclipse

Question

package com.confirm;
  import org.openqa.selenium.Alert;
  import org.openqa.selenium.By;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.firefox.FirefoxDriver;
  import org.testng.annotations.Test;
  public class ConfirmDemo {
    WebDriver driver = new FirefoxDriver();
    @Test
    public void ExampleForConfrim() throws InterruptedException {
     driver.manage().window().maximize();
     driver.get("file:///C:/confirm.html");
     Thread.sleep(2000);
     driver.findElement(By.xpath("//button[@onClick='confirmFunction()']"));
     Alert alert=driver.switchTo().alert();
     System.out.println(alert.getText());
     alert.dismiss();
     driver.close();
 }
}

This is my first selenium program. I type this code in eclipse and also add external jar files for selenium, when I run the eclipse says :

The selection cannot be launch, and there are no recent launches.

How to solve this?

It looks like this issue has more to do with eclipse than it does with Selenium, check out this question and it's answer.
