iText and Spring MVC - Create report from objects list

I need to create a report (PDF file) with a list of objects from my controller class. I'm using Spring MVC and the method is as follow:

Controller method:

@RequestMapping(value = "/publicationsPDF")
public List<Publication> publicationsList(Model model){
    List<Publication> publications = publicationService.publicationsList();
    model.addAttribute("publications", publications);
    return publications;
}

But I don't know how to get all those objects into my table.

public class PublicationsPDF extends AbstractPdfView{

@Override
protected void buildPdfDocument(Map<String, Object> model,
        Document document, PdfWriter writer, HttpServletRequest request,
        HttpServletResponse response) throws Exception {

    // Here I need to get all those objects placed in my controller class and then list them in table.

    PdfPTable table = new PdfPTable(3);
    tabla.setWidthPercentage(100.0f);
    tabla.setWidths(new float[] {1.0f, 3.0f, 6.0f});
    tabla.setSpacingBefore(10);

    PdfPCell column = new PdfPCell();
    columna.setBackgroundColor(BaseColor.LIGHT_GRAY);
    columna.setPadding(3);

    columna.setPhrase(new Phrase("ID"));
    tabla.addCell(column);

    columna.setPhrase(new Phrase("Title"));
    tabla.addCell(column);

    columna.setPhrase(new Phrase("Content"));
    tabla.addCell(column);

    document.add(table);

    }
}

What I need to do in order to get a report with all those objects? Thanks.
