This looks like a JSP compiler error, not a stack trace. What is that up
there?

dataBytes, startPos, and endPos appear to have no relationship to each
other. dataBytes is presumably the content of the file being posted, and
startPos and endPos are clearly indexes into the 'file' string.
It seems more natural to loop over the input and dump it into the
output, instead of reading the entire file into memory and then writing
to the output file. Perhaps you have some requirements I do not understand.
