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:
java.lang.ArrayIndexOutOfBoundsException

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
