I wuold have a page with a fixed number of row in my pdf. Ex: I wuold 20 rows. If I have only 10 rows to print, I would like 10 empty rows (with borders). Is it possible?

I try to create a PDF file. In a pc it's ok, in a second pc I have this error: javax.xml.parsers.FactoryConfigurationError: Unexpected InvocationTargetException at javax.xml.parsers.DocumentBuilderFactory.newInstance(Unknown Source) at net.sf.jasperreports.engine.util.JRStyledTextParser.<init>(JRStyledTextParser.java:112) at net.sf.jasperreports.engine.fill.JRBaseFiller.<init>(JRBaseFiller.java:152) at net.sf.jasperreports.engine.fill.JRVerticalFiller.<init>(JRVerticalFiller.java:92) at net.sf.jasperreports.engine.fill.JRVerticalFiller.<init>(JRVerticalFiller.java:74) at net.sf.jasperreports.engine.fill.JRFiller.createFiller(JRFiller.java:147) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:83) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:601) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:517) at net.sf.jasperreports.engine.JasperRunManager.runReportToPdfFile(JasperRunManager.java:349)
