POI HWPF - How to set custom size of page layout

[Borko Djurovic]

I have this simple code. I want to change page layout of "Document.doc". Example: A4, A3 or some custom values of width and height.
I spend more time to find way to do this. Please help.

...

   
public static void main(String[] args) {
   File file = new File("");
   String path = file.getCanonicalPath() + "\\src\\resources\\Document.doc";
   file = new File(path);
   FileInputStream in = new FileInputStream(file);
   HWPFDocument doc = new HWPFDocument(in);
		
   Range range = doc.getRange();
		
   FileOutputStream out = new FileOutputStream(file);
   doc.write(out);
   out.close();
