Creating PDF using itext

[Fernando Dominguez]

Hi there,
I’m having a little issue creating PDFS using the itext lib.

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.text.pdf.PdfPTable;
private String archivo = “C:/”;
private PdfWriter writer = null;


public void createPDF(MyClass arg) throws Exception{
		Document documento = new Document(PageSize.LETTER, 80, 80, 75, 75);

		
		writer = PdfWriter.getInstance(documento, new FileOutputStream(archivo));
		
	
		documento.open();

		documento.add(createTable(arg));
		

		documento.close(); 
		
		
		writer.close();
	}

This code creates pdfs in the file system one by one.

Everytime I create one I need to get an instance of new FileOutputStream(archivo).

I would like to create PDFs in memory (object), and after having created all of them, write to disk

Is it possible using this lib without making too many changes?

Thanks

Sure, just write the documents into ByteArrayOutputStreams instead of FileOutputStreams. Then you can write the resulting byte[] to FileOutputStreams when you're done. That will of course use up more memory, which may or may not be a problem under the circumstances.

What is the reason for not wanting to write out files as soon as the documents are created?

Thank you for your quick reply!

For whatever reason there were any problems creating any pdf I would have to delete all of them.

So, I think is better to make sure that everything goes well before writting to disk.

Thanks.
