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"));
        }

}


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?

Not sure if you've solved your problem yet, but it
looks like the problem is in your Hashtable.

Fixing that first, might eliminate the other errors.
