E ai!
tenho algo que pode te ajudar

[code] public void preProcessPDF(Object document) throws IOException,
BadElementException, DocumentException {
Document pdf = (Document) document;

	ServletContext servletContext = (ServletContext)
	FacesContext.getCurrentInstance().getExternalContext().getContext();
		
	String logo = servletContext.getRealPath("") + File.separator + "template/img" + File.separator + "logo_topo.png";
	
	System.out.println(logo);
	
	HeaderFooter header = new HeaderFooter(new Phrase("Tabela de produtos"), false);
	pdf.setHeader(header);		
	if(!pdf.isOpen()) {
		pdf.open();
		pdf.add(Image.getInstance(logo));
	}
}[/code]

as dependencias no maven

		 <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>3.7</version>
        </dependency>
         <dependency>

            <artifactId>itext</artifactId>
            <version>2.1.7</version>
          </dependency>

Não uso Maven no meu projeto e fiz conforme o exemplo da documentação do Primefaces.
Está dando o seguinte erro: java.lang.ClassCastException: com.lowagie.text.Document cannot be cast to com.itextpdf.text.Document.

O erro ocorre no cast do Object document para o Document pdf.

Como fazer o cast??? Você saberia me dizer???

Minhas libs: itext 2.1.7.jar, itext 2.1.7.js2.jar e itextPdf 5.5.2.jar

Obrigado pela atenção.
