How to print text without dataset?

[andber]

I am needing print only a attributes from a object without DB connection and dataset.

I have for example the object "Student" and I need print the following attributes:
Name
Last Name
Year

I am using the following source code:

        try {
            String strFile;
            Map Data= new HashMap();

            Data.put("Name", "Pepe");
            Data.put("Lastname", "Perez");
            Data.put("Year", "2010");
 

            strFile = "StudentReport.jasper";

            JasperReport masterReport = null;
            masterReport = (JasperReport) JRLoader.loadObject(strFile);

            JasperPrint jp = JasperFillManager.fillReport(masterReport, Data, new JREmptyDataSource());

            JasperViewer view = new JasperViewer(jp,false);

            view.setTitle("title");
            view.setVisible(true);
           

        } catch (JRException ex) {
            Logger.getLogger(ImpApp.class.getName()).log(Level.SEVERE, null, ex);
        }

This code print a withe paper, why? I need this print the data:
Pepe
Perez
2010

How I can do that?

Thanks in advance,
Andrés.

Take a look at this post:

Maybe what you really need is a JRBeanDataSource. Very simple to use. You pass a collection of your own beans to the reports as a datasource, so the fileds of the report are your bean's fields (whth getter and setters).

 

hope it helps
