public class PdfCheck1{
        public static void main(String ar[])throws Exception{
                Viewer view = new Viewer();
                InputStream input = new FileInputStream("E:\\Imran\\PRO\\PDF\\ListofPages.
pdf");
                view.setDocumentInputStream(input);
                System.out.println(view.getPageCount());
                System.out.println(view.getProperty("Default_Zoom_Type"));
        }

}

What are the details of the exception?

What does the documentation have to say about
the "getProperty(*)" method if it can't satisfy
the request?
