Use servlet read .csv file by ie, but why two more " ?

Question

Hi , friends
following is the key method in my servlet used to read .csv file to ie , but , after I read file to client side , I found that in the both sides of every line " was added, so the csv file can have only one column (many columns was merged into one column), that was not what i want, who guys can find some idea? thanks for your enthusiasm!
void serveRemoteFile(String sFileName, String sContentType, HttpServletRequest req, HttpServletResponse res, StringBuffer sbLog, Runtime rt){
FileInputStream in = null;
ServletOutputStream out = null;
byte bBuf[] = null;
int nLen;
if (isBlank(sContentType) || isBlank(sFileName))
return;
res.setStatus(res.SC_OK);
res.setContentType(sContentType);
res.setHeader("Content-Disposition", "inline;filename= temp.csv");
try {
in = new FileInputStream(sFileName);
out = res.getOutputStream();
bBuf = new byte[1024];
while ( (nLen = in.read(bBuf,0,1024)) != -1) {
out.write(bBuf, 0, nLen);
out.flush();
out.close();
}catch (FileNotFoundException e){
errorPage(req,res,sbLog);
}catch (IOException e){
errorPage(req,res,sbLog);

Excel uses a weird CSV file format. You can find more information about it and a Java library to read data from it here:
