Blank PDF even with the simplest Jasperreport jrxml

Question

i have a EJB site with glassfish 3.1 + JSF for jasperreport 4.0.1. the site has no problem on streaming pdf, but it products blank PDF while printing PDF with runReportToPd

Answer 1

When you are not using the details band, just static values, you can do the following:

Right click in the iReport project, then select 'Properties', search for the property 'When no Data', and select 'All Sections, No Detail'

It works for me, using iReport 4.0

Answer 2

After all, JasperRunManager.runReportToPdfStream(reportStream, servletOutputStream, parameterMap, new JREmptyDataSource()); solved the problem.

Quote from Sanda of Jasperreport:

By default, when no datasource info is present in a report, JR generates no pages. Another option (which can be set in the report's whenNoDataType attribute) would be to print all report sections, excepting the <detail>.

This report contains a detail section, but only with some static data. To ensure this section will be printed too, the simplest way is to provide an empty data source, containing a single empty record.

Answer 3

In addition to what Mythox said, I'll show the best way to fake a data source in jasper and if you need also on JasperServer.

1) Define an Empty Data Adapter (a simple .xml file), and deploy it in Server or put it in reports folder:

<?xml version="1.0" encoding="UTF-8" ?><emptyDataAdapter class="net.sf.jasperreports.data.empty.EmptyDataAdapterImpl"><name>Nuovo Data Adapter 1</name><recordCount>1</recordCount></emptyDataAdapter>

2) Link it into the main report:

<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="repor" language="javascript" pageWidth="612" pageHeight="792" whenNoDataType="NoDataSection" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" isFloatColumnFooter="true" uuid="c0eee90e-1b1a-4f34-ad99-1112847752de">
<property name="net.sf.jasperreports.data.adapter" value="EmptyDataAdapter.xml"/>

prefix "repo:" to the value of the property for the data adapter, if the xml is deployed on jasper server.

The attribute "whenNoDataType" will be ignored.
