Jasperreports not working on Linux server without X11: "Error initializing graphic environment."

[zbigniew.nitecki]

Hi!

I have a huge problem. I was coding an app which is using Jasperreports. Everything was perfectly fine when I was working locally. But then, when I have dockerized my app, when I run the method that should produce an PDF file, I get an error:

Request processing failed; nested exception is net.sf.jasperreports.engine.JRRuntimeException: Error initializing graphic environment.[/code]

I have found out that running my app with
 

-DJava.awt.headless=true[/code]

the problem would solve itself. But it is not.

To be sure that I havent forgotten anything, here is the code of the method which is generating the PDF files, maybe there is something wrong there...
 

The error is coming from this line:

mainReport = JasperFillManager.fillReport(report, invoiceMap, new JREmptyDataSource());[/code]

And here is the method:

public byte[] generateInvoicePDF(Invoice invoice) {        /* Map to fill in main JasperReport */        Map<String, Object> invoiceMap = new HashMap<String, Object>();        invoiceMap.put("FIRST_NAME", invoice.getFirstName());        invoiceMap.put("LAST_NAME", invoice.getLastName());        invoiceMap.put("REGON", invoice.getRegon());        invoiceMap.put("NIP", invoice.getNip());        invoiceMap.put("BUSINESS_NAME", invoice.getBusinessName());        invoiceMap.put("BUSINESS_LOCATION", invoice.getBusinessLocation());        invoiceMap.put("ORDER_DATE", invoice.getOrderDate());        invoiceMap.put("RECEPTION_DATE", invoice.getReceptionDate());        invoiceMap.put("CONTRACT_DATE", invoice.getContractDate());        invoiceMap.put("CONTRACTOR_COMMENT", invoice.getContractorComment());        invoiceMap.put("INVOICE_NUMBER", invoice.getInvoiceNumber());        invoiceMap.put("INVOICE_ISSUE_DATE", invoice.getInvoiceIssueDate());        JasperPrint mainReport;        JasperPrint tableReport;        try {            InputStream invoiceJasper = InvoiceGeneratorServiceImpl.class.getResourceAsStream("/invoices/invoice.jrxml");            InputStream taskTableJasper = InvoiceGeneratorServiceImpl.class.getResourceAsStream("/invoices/invoice_sub.jrxml");            JasperDesign mainReportDesign = JRXmlLoader.load(invoiceJasper);            JasperDesign tableReportDesign = JRXmlLoader.load(taskTableJasper);            JasperReport report = JasperCompileManager.compileReport(mainReportDesign);            JasperReport table = JasperCompileManager.compileReport(tableReportDesign);            /* List to hold Items */            List<InvoiceTask> taskList = new ArrayList<>();            /* Add Items to List */            taskList.addAll(invoice.getInvoiceTasks());            /* Convert List to JRBeanCollectionDataSource */            JRBeanCollectionDataSource itemsJRBean = new JRBeanCollectionDataSource(taskList);            /* Map to hold Jasper report Parameters */            Map<String, Object> taskListMap = new HashMap<String, Object>();            taskListMap.put("TasksDataSource", itemsJRBean);            taskListMap.put("ADDITIONAL_COSTS", invoice.getAdditionalCosts());            mainReport = JasperFillManager.fillReport(report, invoiceMap, new JREmptyDataSource());            tableReport = JasperFillManager.fillReport(table, taskListMap, new JREmptyDataSource());            List<JasperPrint> printList = new ArrayList<>();            printList.add(mainReport);            printList.add(tableReport);            JRPdfExporter exporter = new JRPdfExporter();            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();            exporter.setExporterInput(SimpleExporterInput.getInstance(printList)); //Set as export input my list with JasperPrint s            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(byteArrayOutputStream));            SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();            configuration.setCreatingBatchModeBookmarks(true); //add this so your bookmarks work, you may set other parameters            exporter.setConfiguration(configuration);            exporter.exportReport();            return byteArrayOutputStream.toByteArray();        } catch (JRException e) {            e.printStackTrace();        }        return new byte[0];    }[/code]
