How to capture screenshot on Failure?

These are the frequent questions.................It will be good if we capture screenshot if our test fails...
We need to use try and catch block..if try block catches the exception..it will execute the capture screenshot command which is written in catch block..


Below is the sample code how to capture screenshot on failure...........

--------------------------------------------------------------------------
import org.junit.*;


import org.openqa.selenium.server.*;

import com.thoughtworks.selenium.*;

public class Screenshot extends SeleneseTestCase{

public Selenium selenium;

public SeleniumServer seleniumserver;


@BeforeClass
public void setUp() throws Exception {
seleniumserver = new SeleniumServer();
selenium = new DefaultSelenium("localhost", 4444, "*iexplore", "http://");
seleniumserver.start();
selenium.start();
}
@Test
public void testScreenshot() throws Exception
{

try {
selenium.open("http://in.yahoo.com//?p=us");
selenium.windowMaximize();
selenium.click("//li[@id='pa-u_14782488-bd']/a/span[2]");
selenium.waitForPageToLoad("30000");
selenium.type("username", "test");
Thread.sleep(1000);
//the element name for password field is "passwd" But here i changed it to "passd" which is wrong.
//Selenium will capture screen shot after the error
selenium.type("passd", "123");
selenium.click(".save");
selenium.waitForPageToLoad("30000");
}
catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
selenium.captureScreenshot("C:\\test\\erro.png");
}

}


@AfterClass
public void tearDown() throws InterruptedException{
selenium.stop();
seleniumserver.stop();
}
}
