Olá pessoal,

<%@ taglib uri=“http://java.sun.com/jsf/html” prefix=“h”%>
<%@ taglib uri=“http://myfaces.apache.org/tomahawk” prefix=“t”%>

<%@page import=“br.com.getnet.valegas.controller.mbean.PinMBean” %>
<%@page import=“java.util.*” %>

<%@ taglib uri=“http://displaytag.sf.net” prefix=“display” %>

<%
List pinsVendidos = PinMBean.getListaPinsVendidos();
request.setAttribute(“pinsVendidos”,pinsVendidos);
%>

Relatório de Pins Vendidos

        <display:setProperty name="export.pdf.filename" value="relatorio.pdf"/>
        <display:setProperty name="export.pdf" value="true" />
