JasperReports 1.3.4 -> problem (JREvaluator)

Hi,

I have just started integrating Jasper Reports into my application....I use maven as my build tool..I have included the dependency of 1.3.4 into my pom.xml file

I have written a simple test case which uses the deprecated Jasper Manager (just for my initial tests) to generate the pdf file...

JasperDesign jasperDesign = JasperManager.loadXmlDesign("e://reports//PortfolioSummaryReport.jrxml");
JasperReport jasperReport = JasperManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("reportTitle","Portfolio Summary");

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,parameters,new JREmptyDataSource());
JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,outFile);
exporter.setParameter(JRExporterParameter.JASPER_PRINT,jasperReport);
exporter.exportReport();

The bold lines seem to be the problem...I get the following problem while trying to execute the test case, but I can see this class very much within the jar file (jasperreports.1.3.4.jar)...I am clueless...please help
