Esta e a classe q uso

PRECISO DE AJUDA

estranho o erro a unica coisa q esta diferente da maneira q eu uso é…
ve se entende… agora certifique tbm se seus atrinutos esta com os tipos correto tanto nos fields qto nos que estao no formulario entendeu ?
integer = integer etc…

byte[] bytes = null;

try {

// carrega os arquivos jasper

File reportFile = null;

reportFile = new File(servletContext.getRealPath("/report/" + arquivoJasper));

JasperReport relatorioJasper = (JasperReport)JRLoader.loadObject(reportFile.getPath());

File reportSubFile = null;

// Caso tenha subReport

if(arquivoSubJasper != null && arquivoSubJasper != “”){

reportSubFile = new File(servletContext.getRealPath("/report/" + arquivoSubJasper));

}

// parâmetros, se houverem

if(arquivoSubJasper != null && arquivoSubJasper != ""){
        	parametros.put("subRel",jrDSSub);
        	parametros.put("subFile",reportSubFile);
        }
       
        bytes = JasperRunManager.runReportToPdf(relatorioJasper,parametros,jrRs);
        
    } catch (JRException e) {

//        	e.toString()

e.printStackTrace();

}

if (bytes != null && bytes.length > 0) {

// envia o relatório em formato PDF para o browser

response.setContentType(“application/pdf”);

response.setContentLength(bytes.length);

ServletOutputStream   ouputStream = response.getOutputStream();

ouputStream.write(bytes, 0, bytes.length);

ouputStream.flush();

ouputStream.close();

}
