Hi,
I used a servlet to protect my html and image files. I
need to read this files and send them to the response
flow.
It's working, but when the file is too long (for
example, in the case of some JPEG or GIF files), a
byte seems to be
bad and corrupts the result.
Does anyone have the same problem and how to solve it?
regards,
Sylvain MARGA
ps: The code of the method is:
public void returnFile(String filename,
ServletOutputStream out) throws FileNotFoundException,
IOException {
// A FileInputStream is for bytes
FileInputStream fis = null;
int i=0;
try {
fis = new FileInputStream(filename);
byte[] buf = new byte[4*1024]; // 4K buffer
int bytesRead;
while ((bytesRead = fis.read(buf)) != -1 ){
out.write(buf, 0, bytesRead);
}
}
catch(Exception e) {
System.out.println("file error:"+e);
}
finally {
if (fis != null) fis.close();
}
}
and I call it with:
ServletOutputStream out = response.getOutputStream();
response.setContentType(
getServletContext().getMimeType(request.getPathTranslated())
);
returnFile( request.getPathTranslated() , out );
