[eluser]dunialebah[/eluser]

Code:

$this->load->library('PHPJasperXML');
  

  $path = site_url('report/report1.jrxml');
  //echo $path;
  //echo htmlspecialchars($path);
  
  $xml =  simplexml_load_file($path);
  
  //var_dump($xml);
  
  $PHPJasperXML = new PHPJasperXML();
  $PHPJasperXML->debugsql=true;
  $PHPJasperXML->arrayParameter=array("parameter1"=>"this isi a parameter");
  $PHPJasperXML->xml_dismantle($xml);
  
  
  
  //$PHPJasperXML->transferDBtoArray('localhost','root','','cms8');
  $PHPJasperXML->outpage("D");    //page output method I:standard output  D:Download file

That's my code but I got small blank pdf file without file name
