Answer 1

try this:
try
{
driver.manage().timeouts().implicitlyWait(1000, TimeUnit.MILLISECONDS);
err=driver.findElement(By.xpath("//*[#id='Error']/div/p"));
}
catch(NoSuchElementException e)
{
//Log your error
}
finally
{
driver.manage().timeouts().implicitlyWait(15000, TimeUnit.MILLISECONDS);
}
This will tell the driver to only take 1 second to search for the "err" element before throwing an exception. It will also reset the implicit wait, even in the event of an exception.
