JasperFillManager.fillReport NullpointerExcep

2006-01-26 05:43

When I try to run the code



System.out.println("reportFileName = " + reportFileName);

System.out.println("parameters = " + parameters);

System.out.println("con = " + con);

JasperPrint printer = JasperFillManager.fillReport(reportFileName, parameters, con);


I get


reportFileName = C:capesJColetaAPPrelatoriocol_rel_producao_intelectual_conf.jasper

parameters = {natureza=B, tipoproducao=3, anobase=2004, idprograma=33002010125P7}

con = org.hsqldb.jdbc.jdbcConnection@e48e1b

Exception in thread "main" java.lang.NullPointerException

Are you using Hashtable for the parameters map? If so, switch to HashMap because the code assumes that the map supports null values.
