The report generation code looks like this.

public class ReportGenerator
{
    private String REPORT_pdf     = "src/main/resources/report.pdf";
    private String REPORT_pattern = "src/main/resources/jrxml/medicalFacility.jrxml";
    private Map<String, Object>  parameters =new HashMap<>();


    private JasperDesign jasperDesign;
    private JasperReport jasperReport;
    private JasperPrint  jasperPrint ;

    public void create() throws JRException
    {

        jasperReport  = JasperCompileManager.compileReport(REPORT_pattern);


        Session sesssion = Main.getOurSessionFactory().openSession();
        Transaction transaction = sesssion.beginTransaction();
        sesssion.doWork(new Work() {
            @Override
            public void execute(Connection connection) throws SQLException {
                try {
                    jasperPrint   = JasperFillManager.fillReport(jasperReport, parameters,connection);
                    JasperExportManager.exportReportToPdfFile(jasperPrint,REPORT_pdf);
                } catch (JRException e) {
                    e.printStackTrace();
                }
            }
        });
        transaction.commit();

    }

    public void setREPORT_pattern(String pattern){
        REPORT_pattern = pattern;
    }

    public void addParam(String key, String value){
        parameters.put(key, value);
    }

    public void clearParames() {
        parameters.clear();
    }
}

And it is called like this.

ReportGenerator rg = new ReportGenerator();
            rg.setREPORT_pattern("src/main/resources/jrxml/appointmentResult.jrxml");

            rg.clearParames();
            rg.addParam("MedicalFacility", officeEntity.getDepartment().getHousing().getMedicalFacility().getName());
            rg.addParam("FIOpatience",patienceEntity.getFio());
            rg.addParam("Conclusion",textField.getText());
            rg.addParam("DoctorFIO",staffEntity.getFio());

            rg.create();

The screenshot below shows that the parameters came in correctly, but still, instead of the report, there is a white sheet.

Figase.
You can read the listing, looking at night. For literary gourmets
