java.lang.NoClassDefFoundError: with EJB and JasperReports-Collection of common programming errors

I need to generate a report using iReport 5.0 for my EJB application.

When I’m calling report from my front end it works fine but when I’m trying to call same report in my EJB module it gives me a no class def found error.

This is how I call my report:

Map parameters = new HashMap();

parameters.put("Emp_ID", empNo);
parameters.put("From", startDate);
parameters.put("To", endDate);

Connection conn = DB_Conn.getDataBasConnection();
JasperDesign jDesign = JRXmlLoader.load("C:\\SalesRep_Sales_Sub01.jrxml");

JasperReport jasperReport = JasperCompileManager.compileReport(jDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters,conn);
JasperViewer.viewReport(jasperPrint,false);

And these are the libraries I use:

• jasperreports-4.5.0
• commons-beanutils-1.8.2
• commons-collections-3.2.1
• commons-digester-1.7
• commons-javaflow-20060411
• commons-logging-1.1
• groovy-all-1.7.5
• jcommon-1.0.15
• jfreechart-1.0.12

Can someone please tell me what is the method to call my report from EJB and is there any additional libraries i should use.

Error report generate in output:
