when PrintWriter.flush() is called

I'll assume that the servlet container will call the flush() or close() method sometime while serving a request to one servlet because we don't have to code close() or flush() in our code. Does anyone know when this "commit" happens?
Thanks in advcance ...

Personally I always prefer to code an explicit out.close(). With earlier versions of Tomcat, this solved some mysterious blank pages, so ever since then I have used an explicit close(). I don't think you can depend on close being called automatically in servlets.
I know that the finalize methods for various java.io streams call close, so I suppose that garbage collection would eventually force it.

It is sorta covered in the JavaRanch Style Guide.
