I did a report with iReport, when I test it inside of iReport works, but when I do the preview in the program but it takes a lot of minutes to do it.
Why?
this is the code:

Code:

      String reportSource = "./report/test3.jrxml";
       HashMap params = new HashMap();
       JRDesignQuery queryReport = new JRDesignQuery();
       params.put("something","1"); 
      
       try
       {
           JasperDesign diReport= JRXmlLoader.load(reportSource);
           queryReport.setText(consult);
           diReport.setQuery(queryReport);
           JasperReport jasperReport = JasperCompileManager.compileReport(diReport);
           JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, DB.getConnection());
           JasperViewer ReporttoPreview = new JasperViewer(jasperPrint,false); 
           ReporttoPreview .setTitle("lawyers");
           ReporttoPreview .show();

plz help me!!
