Java servlet and IO: Create a file without saving to disk and sending it to the user

Question

I`m hoping can help me out with a file creation/response question. I know how to create and save a file. I know how to send that file back to the user via a ServletOutputStr

Answer 1

You don't need to save off a file, just use a ByteArray stream, try something like this:

inputStream = new ByteArrayInputStream(text.getBytes());

Or, even simpler, just do:

stream.write(text.getBytes());

As cHao suggests, use text.getBytes("UTF-8") or something similar to specify a charset other than the system default. The list of available charsets is available in the API docs for Charset.
