Hi there,
I have a servlet which sends a lot of text to the response PrintWriter based on a db lookup. At the end of each paged served by this servlet I want to output an info about the size of the page the web visitor just has retrieved, e.g.:
"This page is 36.340 bytes in size."
Any idea how to do this? There seems to be no getContentSize method available in HttpServletResponse.

You could create a StringWriter as a local buffer and write everything to it , get the size, then output the resulting String.

How do I output the StringWriter via the response-Object?
