Can not download the PDF

Selenium is a good idea.

I try run your code but got the exception as follow:
...
WebDriverException: ChromeDriver executable needs to be available in the path. Please download from http://chromedriver.storage.googleapis.com/index.html and read up at http://code.google.com/p/selenium/wiki/ChromeDriver
...

...
If i had a working log this would probably work,because now it simulate a browser.
...

What a working log do you mean here?
