Answer 1

Seems like you have two problems here:

1. Your 'application/views/scripts/error/error.phtml' is missing. You can restore it and you'll get more accurate exception message at once.
2. Your helper class should contain a method named after the helper.

So, in your case it's file My/View/Helper/Example.php with the following body

class My_View_Helper_Example extends Zend_View_Helper_Abstract {
  public function example() {...}
}

Then you'll be able to call it from the view with

$this->example()

Answer 2

In addition to Vikas answer.

To call more than one method in a view helper you can use code like this:

In My/View/Helper/Example.php

class My_View_Helper_Example extends Zend_View_Helper_Abstract
{
    public function example()
    {
        return $this;
    }

    public function foo()
    {
        return 'foo';
    }

    public function bar()
    {
        return 'bar';
    }

    public function __toString()
    {
        return $this->foo();
    }
}

In you views:

echo $this->example()->foo() // prints foo
echo $this->example()->bar() // prints bar
echo $this->example() // prints foo
