Question

I am using FileInputStream in Spring MVC to read a chunk of a file into a byte[] buffer.

I then write (using FileCopyUtils.copy) the buffer to the response stream.

I notice that the response that is written to the stream (what the user receives) looks similar to the file, but there are blemishes.

1. before the file data, there is a ‘2000’ (without quotes) at the top of the file.
2. this ‘2000’ string is sporadically present throughout my file
3. The file ends with a ‘0’

none of these exist in the original file that is being read from. Can anyone help me get rid of these so that I have an accurate output stream?

here’s an example of what my incorrect ouput looks like:

2000
a line of data
a line of data
a line of data
a line of data
a line of data
a line of data
a line o
2000
f data
a line of data
2000

a line of data
a line of data
0

it should just be:

a line of data
a line of data
a line of data
a line of data
a line of data
a line of data
a line of data
a line of data
a line of data
a line of data

Thanks!

my guess is that the stream is specified as a chunked transfer encoding and your simply reading it as is
