Using getInputStream and file upload

I am uploading a zip file to my server. I use getInputStream to read, while I write to an output stream (either FileOutputStream, or RandomAccessFile "rw"). This is done in a loop.
When I view my uploaded zip file on the server, it tells me there was "206 extra bytes at beginning or within zipfile." This makes my zipfile unable to get processed with another class's method. I get a ZipExeption. I tried setting my content type as both ("text/html") and not setting it at all (not sure why I did that). Any help would be greatly appreciated.
Thanks,
Tom

I have to ask why you are trying to re-invent the wheel here. Orielly has an amazing upload package that handles all this in 1 or 2 lines of code!

I like the wheel round like it is, so I will not try to re-invent it. I'll check that out. It would sure save a lot of frustration. Thanks for the reply.

I think you should use setContentType("multipart/form-data")
