Java 无法使用Jasper报表生成pdf

我能够生成byte[]对象，但是在刷新字节时，我得到的异常是

org.apache.catalina.connector.ClientAbortException: java.net.SocketException: Broken pipe

我正在使用Ajax调用servlet

$.ajax({
        url: 'CertServlet',
        dataType: 'json',
        type: 'post',

        data: data,
        success: function( data, textStatus, jQxhr ){

        error: function( jqXhr, textStatus, errorThrown ){
            console.log( errorThrown );
        }
    });

我的servlet代码

byte[] output = null;
    try {
        output = JasperExportManager.exportReportToPdf(jasperPrint);
    } catch (JRException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 
    System.out.println(output); --> This has value
    response.reset();
    response.resetBuffer();
    response.setHeader("Content-Disposition", "inline;filename=Sample.pdf");
    response.setContentType("application/pdf");
    response.setContentLength(output.length); 
    ServletOutputStream out = null;
    try {
        out = response.getOutputStream();       
        out.write(output,0,output.length);
        out.flush();
        out.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

总的例外是
