Response had already been committed

Question

hello,
i have a struts application which saves a file to databse as BLOB. on click of alink this file has to be read from database and opened in browser. i do this by first reading from blob and write it to a file and then read it from the file and write to the response. i am able to read this file from databse and write it to a file on the physical drive. but i am not able to write the file in response so that it goes to browser.
i get the following error.
: java.lang.IllegalStateException: Response has already been committed.
the code snippet to write to response is as follows.
response.setContentType(oscDVO.getM_strContentType());
response.setHeader("Content-Disposition","attachment;filename=\"" + oscDVO.getM_strFileName()+"\"");
ServletOutputStream outputStream = response.getOutputStream();
File file = new File("C:\\"+oscDVO.getM_strFileName());     FileInputStream fileInputStream = null;
fileInputStream = new FileInputStream(file);
BufferedInputStream bis=new BufferedInputStream(fileInputStream);
int nByte = bis.read();
boolean b=false;
while(nByte != -1)
outputStream.write(nByte);
nByte = bis.read();
i am in urgent need of solution. i hv searched on most of the forums but hv not got any solution. if anyone has ever implemented similar knd of functionality pls help.
thanking in advance.

Answer 1

thnkou for ur quick response.
i tried closing the streams as well.
but the problem persists.
if i try to open a word document, the document opens properly, the same error of response committed ocurs but i think ms word truncates tthe error. but if i open the same doc file in any other editor, the error is displayed at the bottom of the correct data.
but with very small text files of less than1 kb also , i get this error.
