Did you mean a NullPointerException?  

If so, 
a) Please don't SHOUT at us.
and
b) Please be specific.  

Programming is hard.  Debugging is harder.
Debugging an application remotely, where the 
exceptions and errors are being 'paraphrased' is 
even harder again.

Don't make it hard on us (please).

I would have guessed that if any property either does not
exist, or is not defined for that PDF file, it returns null.  

OTOH, that does not explain the exception, since the output
should simply have been 
null
like this line would print..
  System.out.println((String)null);

Indeed, the NPE suggests the viewer itself is null, but if 
so, the page count could not have been referenced on the
previous line*.

Which leads me to..
Please copy/paste the stacktrace.  As well as the 
output you are seeing.
