IllegalStateException on writing Bytes to OutputStream

[rtarar]

When writing bytes to the servlet out put stream.I get the fowwloing error.
I am trying to push a pdf report file to the user.

The code the straight forward.Am I missing something?

Any thought would be really welcome.



byte[] bytes = webreport.generateMuiltiReport(results,"single_sample_report",user);
if(bytes != null){
response.setContentType("application/octet-stream");
response.setContentLength(bytes.length);
response.setHeader( "Content-Disposition", "attachment; filename=sample_report.pdf");
ServletOutputStream ouputStream = response.getOutputStream();
ouputStream.write(bytes, 0, bytes.length);
ouputStream.flush();
ouputStream.close();
}
