The bytesRead returns the size of the buffer (8KB) every time. I also debug and
I can't find anything wrong. Input and OutputStream are not null, bytesRead is
the correct size and the buffer is also filled.
Any other ideas?
How big is the file you're sending?
Is there any particular reason to use a buffer?
What happens if you try without it?

Try insert some debug statements just before the out.write.
System.out.println("bytesRead: " + bytesRead) would be interesting.
In fact this is kind of my-first-debugging and you don't even mention you did
try it.

Hi everyone.
I'm stuck with a problem I don't understand. We have a tomcat server and after
redeploying our war file, we get this error:

Notice that there are no number on the first line and it is usually the case.
The code that is "responsible is:
private ServletOutputStream out;
private InputStream in;
...
in = new FileInputStream(tmp);
...
out = response.getOutputStream();
byte[] buf = new byte[8 * 1024]; // 8K buffer
int bytesRead;
while((bytesRead = in.read(buf))> 0) {
out.write(buf, 0, bytesRead);
}
The updated code didn't change anything in that Servlet so I really have no
clue what happened. It happens on tomcat 6.0.18 and 6.0.20. Java is 1.6.0_11.
Thanks for any help.
Best Regards
Geoffrey
