Answer 1

Your code is wrong.

You should pass parameters as below:

Map<String, Object> map = new HashMap<String, Object>();
map.put("frm_date", frm_dte);
map.put("to_date", to_dte);

You don't need to add P${} to the parameter's name.

There are a lot of samples in JasperReports distribution package.

You can look at this sample for more details.

private JasperPrint generateReport() {
    Connection conn = null;
    JasperPrint myJPrint = null;
    try {

        conn =yourconnectionName;

        // parameters to be passed to the report
        Map<String, Object> params = new HashMap();

        // Loading my jasper file
        JasperDesign jasperDesign = null;
        JasperReport jasperReport = null;

        params.put("REPORT_DIR",yourClassName.class.getClassLoader()
                        .getResource("yourJasperFileName.jrxml").toString().replace("yourJasperFileName.jrxml", ""));
        jasperDesign = JasperManager.loadXmlDesign(yourClassName.class
                .getClassLoader().getResourceAsStream("yourJasperFileName.jrxml"));
        params.put("joining_date", frm_dte);
         params.put("leaving_date", frm_dte);
        jasperReport = JasperCompileManager.compileReport(jasperDesign);

        /*
         * Filling the report with data from the database based on the
         * parameters passed.
         */
        myJPrint = JasperFillManager.fillReport(jasperReport, params, conn);
        params.clear();

    } catch (JRException ex) {
        ex.printStackTrace();
    }

    return myJPrint;

}

You can pass date as string format type as follow,

if(from_date!=null)
{
      formattedEndDate=new SimpleDateFormat("yyyy-MM-dd").format(from_date);
}

if(getStartDate()!=null)
{
    formattedStartDate=new SimpleDateFormat("yyyy-MM-dd").format(to_date);
}
