	private final static String BASE_URL = "http://localhost:8080";
	private final static WebDriver driver = new FirefoxDriver();
	@Before
	public void startUp() {
	driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
	driver.manage().window().setPosition(new Point(0, 0));
	driver.manage().window().setSize(new Dimension(800, 600));
	}
	@Test
	public void testMyPage() {
	final Wait wait = new WebDriverWait(driver, 60);
	driver.get(BASE_URL + "/myweb/");
	boolean isListPopulated = wait.until(WaitForAjax(60000));
	Assert.assertTrue(isListPopulated);
	}
	@After
	public void tearDown() {
	// Close the browser

Import a UTF-8 SQL file into MySQL Server

importing a SQLFile into MySQL works only if the .sql file itself is encoded with default (ISO-????) character set. But if you have file with UTF-8 encoding, it won't work. Saving the file in UTF-8 encoding will not work as well, since mysql doesn't know which encoding is enabled and interprets it as default encoding. Using this command will tell to MySQL to use UTF-8 encoding while importing the Data:

>> mysql -h host -u username -ppassword --default_character_set=utf8 database < myfile.sql
