JasperServer Reports returning Blank page in Yii 1

I designed a report using iReport tool and upload it to JasperReports Server into my local server pc. In iReport and JasperReports Server the report is working perfectly but when I call the report from Yii 1 then it's not working. It's returning blank page instead of Data. I can not find out the issue.

Here is my yii 1 code (using YiiJasper Extension in Yii):

       $re = new JasperReport('/entsol/Reports/AcAccounts',
            JasperReport::FORMAT_PDF, array(
                'pAccountTile' => $pAccountTile,
                'pBranch' => $pBranch,
                'pFromDate' => $pFromDate,
                'pToDate'=>$pToDate,
            )
            );
        $re->exec();
        echo $re->reportToPDF(); //All pages

by using the above code I got blank page instead of data.

How do I get my issue ?
