problem to show a jasperreport from java

[m_ilio]

Hi... I am new in jasper report+ireport and I am testing.
I made a test report from a table without parameters, but when I want show the report, the command JasperFillManager.FillReport(), do nothing

this is the code that I am implementing:

 

        try {
            String report = "C:\reportes\test.jasper";
            Map parameters = null;
            Connection conn =DataBase.conexion;

            JasperPrint print = JasperFillManager.fillReport(report, parameters, conn);
            JasperViewer.viewReport(report, false);

        } catch (JRException ex) {
            JOptionPane.showMessageDialog(this,"Internal error to show the report","Error!",1);
            return;
        }

What is the problem?
