#2760 — PDF Processing

  To: comp.lang.java.gui
Hi members,
     I am PDF Processing...When i tried to execute the following code ,it
thows NULLPOINTER exception...The exception occured at this line System.out.
println(view.getProperty("Default_Zoom_Type"));..... I dont know how to solve
tis.....Please refer the following code and give me the solution for this.....


                    Thank in advance...                                

import com.adobe.acrobat.Viewer;
import java.io.*;
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"));
    }
}

with regards,
J.Imran Baseer.

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).

>...The exception occured at this line System.out.

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.

Huhh..  That is odd, I thought HashTable was able to
accept 'null' values.

(I am bowing out of this thread, for the moment.  Hopefully
one of the Java gurus will spot the problem..)

Well good luck figuring it out on your own.

Well, then I suggest you hire a consultant to give you those answers.
Posting to a free newsgroup, where the answers you get are from
volunteers, and then complaining about it is just bad manners.

I think it unlikely you safely managed to get view.getPageCount() and
then die on view.getProperty.

If view were null, the error would come on view.getPage(Count())
if the property were null, you would simply see the word "null", not a
NullPointerException.  Please add some debug code and check the line
number.
