The link is no longer valid and therefore we don't have any sample pdf.

> Hi,
> I've tried to extract text from this URL:
> http://www.ischool.washington.edu/mcdonald/papers/Lutters.AMCIS00.pdf
> However, it throws java.lang.NullPointerException on me
> although the PDF file does exist on that URL.
> Here's the code where I invoke the PDFTextStripper:
> String docURL =
> "http://www.ischool.washington.edu/mcdonald/papers/Lutters.AMCIS00.pdf";
> try{
>  PDFTextStripper stripper = new PDFTextStripper();
>  PDDocument pdfDoc =
> PDDocument.load(getInputStreamFromURL(docURL));
>  String strippedText = stripper.getText(pdfDoc);
>  pdfDoc.close();
>  return stippedText;
> }
> catch(IOException e){
>  e.printStackTrace();
> }
> Here's getInputStreamFromURL method used in the above code:
> public InputStream getInputStreamFromURL(String url){
>  try{
>   URL myURL = new URL(url);
>   URLConnection con = myURL.openConnection();
>   con.setRequestProperty("User-Agent",""); 
>   return con.getInputStream();
>  }
>  catch(MalformedURLException e){
>   e.printStackTrace();
>  }
>  catch(IOException ie){
>   ie.printStackTrace();
>  }
>  return null;
> }
> Please advise, Thanks
