Answer 1

InputStreams and OutputStreams are not interchangeable, or even particularly convertible. They do inherently different things.
Sometimes it's possible to string them together, but it's not even clear from your code whether that's appropriate for your problem.
Probably you should be creating a whole new output stream, completely separate from the input stream. But who knows; you didn't explain what you're trying to accomplish.
