The mark method in InputStream does not work,
which is given in the API Documentation for that method.
May be you can make a copy of the InputStream or CLONE it
before you try to read the first 8 bytes and then use them
for the 2 different purpose that you want to.Although
this might not be a perfect way.

Subject: Image Information Using MultipartParser
I have successfully implemented the MultipartParser servlet and I have
access to all of the form data. When I get a FilePart I want to read some
of the contents of the raw data. Ideally I want to read 2 bytes of data
starting at the 6th byte (the is the value of the width in a .gif file).
The problem I'm having is that once I read the data the pointer into the
ServletInputStream is on the 8th byte and when the file is written to disk I
lose the first 8 bytes. I cannot seem to use the mark() and reset() methods
of an InputStream - it doesn't work.
Has anyone successfully read the raw data from a FilePart and still written
the file to disk?
Thanks
-John Nelson
