hi, I have tried to edit the default.jasperreports.prop in jasper.jar, but still got the NullPointer exceptions, such as: java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:89) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:628) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:544) What I am trying to do is: user jasper 3.5.3 with spring 3.0.2 on glassfish 2.1. The next line is causing the trouble: jasperPrint = JasperFillManager.fillReport(myFile.getPath(),parameters, jasperDs); All of these parameters are not null, and has valid and good values in it. Any ideas Guys? thx
