[eclipselink-users] Jasperreports and a jpa based java se application

[sirdeaz <frederik.didden@xxxxxxxxx>]

Hi, 

I'm working on an standard java desktop application which uses jpa
(eclipselink 2.0.0) in nb 6.9.0. It's working like a charm. It's fetching
data and displaying it by using jfreechart. 

If I try to create a report, it throws an error stating that it can't find
the persistence.xml file even though all the other jpa functionality is
working. 

The runtime error + code used to create the report is included. 

java.lang.RuntimeException: java.lang.RuntimeException: Unable to load
persistence.xml : META-INFpersistence.xml (The system cannot find the path
specified)

code to create the report: 

public ReportResult generateReportGermany(Warehouse warehouse) throws
Exception { 
        List<ChecklistRecord> records =
ChecklistRecord.findAllByWarehouseAndRouteType(warehouse,
CheckListType.getCheckListTypeForGermany()); 
        return generateReport("Germany", warehouse,
CHECKLIST_DATASOURCE_GERMANY, new JRBeanCollectionDataSource(records)); 
    } 

    private ReportResult generateReport(String country, Warehouse warehouse,
String report, JRDataSource ds) throws Exception { 
        String tempFile = getTempFileName(); 

        HashMap<String, String> parameters = new HashMap<String, String>(); 
        parameters.put("country", translate(country)); 

        // compile 
        JasperReport jasperReport =
JasperCompileManager.compileReport(ClassLoader.getSystemResourceAsStream(report)); 
        // fill it 
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,
parameters, ds); 
        // export to pdf 
        JasperExportManager.exportReportToPdfFile(jasperPrint, tempFile); 
        
        return new ReportResult(tempFile, warehouse); 
    } 

How can I resolve this issue? 

Regards, 

Frederik
