Use the p: dataExporter component of PrimeFaces. It allows you to easily export data from a datatable into EXCEL, PDF, CSV and XML formats.

Here's an example of its use on the PrimeFaces website: link

PDF has a very simple formatting, but you can configure some basic things programmatically, such as margin and orientation:

public static void formatarRelatorioPdf(Document pdf) {
    pdf.setMarginMirroringTopBottom(false);
    pdf.setPageSize(PageSize.A4.rotate());
    pdf.setMargins(-102, -102, 2, 2);
}

Note: The com.lowagie.text.Document class belongs to lib itext .

To make more elaborate PDF documents, you can do them using Jasper Reports and iText or make them in HTML. In both ways you will need research and a little study, but the result is great. I recommend the first option because HTML reports sometimes get some difference between bowsers.

I hope you have helped!
