When we have a servlet that does persistent connection, why do we have to have aByteArrayOutput.writeTo(res.getOutputStream()) even after we already sent out the required info through res.getWriter().println(info)?

You appear to be doing a res.getOutputStream() after you already did a res.getWriter().
By my understanding of the API, that should cause a IllegalStateException to be thrown.
Why do you think "why do we have to"?
What is telling you that you have to do that?

Hi, I am so sorry. It was not res.getWriter() but a PrintWriter(new ByteArrayOutputStream(1024), true).
I agree. Here's the link:
