meu metodo:



@Controller(mBeanRelatorioPais)
@Scope(request)
public class MBeanRelatorioPais {

	@Resource(name = controllerCadastro)
	CadastroFacade paisFacade;

	private List<Pais> paises;

	public void imprimirRelatorioPaises(ActionEvent event) throws Exception {

		FacesContext facesContext = FacesContext.getCurrentInstance();
		ServletContext servletContext = (ServletContext) facesContext
				.getExternalContext().getContext();
		String pathRel = servletContext
				.getRealPath(/relatorios/relatorioPaises.jasper);

		HttpServletResponse response = (HttpServletResponse) facesContext
				.getExternalContext().getResponse();

		try {
			paises = new ArrayList<Pais>();
			paises = paisFacade.listarPaises();
		} catch (Exception e) {
			e.printStackTrace();
		}

		// parametros
		Map<String, Object> parametros = new HashMap<String, Object>();

		// recebe por parametro uma lista da propia classe jah populada
		JRDataSource jrds = new JRBeanCollectionDataSource(paises);

		try {
			if (paises != null && paises.size() > 0) {
				JasperPrint print = JasperFillManager.fillReport(pathRel,
						parametros, jrds);
				byte[] bytes = JasperExportManager.exportReportToPdf(print);
				writeBytesAsAttachedTextFile(bytes, paises.pdf);

			} else {
				System.out.println(Erro);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	protected void writeBytesAsAttachedTextFile(byte[] bytes, String fileName)
			throws Exception {
		if (bytes == null)
			throw new Exception(Array de bytes nulo.);

		if (fileName == null)
			throw new Exception(Nome do arquivo eh nulo.);

		FacesContext facesContext = FacesContext.getCurrentInstance();
		HttpServletResponse response = (HttpServletResponse) facesContext
				.getExternalContext().getResponse();
		response.setHeader(Content-Disposition, attachment; filename=\
				+ fileName + \;);
		response.setContentLength(bytes.length);
		ServletOutputStream ouputStream = response.getOutputStream();
		ouputStream.write(bytes, 0, bytes.length);
		facesContext.responseComplete();
	}

	public List<Pais> getPaises() {
		return paises;
	}

	public void setPaises(List<Pais> paises) {
		this.paises = paises;
	}

No seu relatorio tem algum campo que corresponde a algum metodo com a assinatura get da sua Classe Pais exemplo
/--- campo especificado no jrxml---/
%P

/--- Método corresspondente no Pais.java ---/
public String getNome(){
// conteudo comentado
}
