The tech tip below shows how to dynamically create an image within a
servlet and send it to the output stream.

http://developer.java.sun.com/developer/JDCTechTips/2001/tt0821_update.html

In most cases developers want to send both HTML text and images when
dynamically creating a web page.  How can this be done?

"The Servlet specification requires that servlets not call both
ServletResponse.getOutputStream() and ServletResponse.getWriter(). "

So, the only way I can think of doing this (images and HTML) is to
transform the HTML text into a byte array and use the method
write(byte[] b) from the class OutputStream.

Can anyone think of a more elegant way to do this?

Also, "Because JSP pages already call getWriter(), they must not also
call getOutputStream()."  I think this means that it is impossible to
dynamically create images from a JSP (which was the point of the tech
tip above).

Can anyone think of a way to dynamically generate images within a
JSP?
