Question regarding error: Response has already been committed

[Jason Shaffer <ja...@theprairie.com>]

I receive the following error when I attempt to load Apply.jsp of the xsl
example that comes with the jakarta-taglibs nightly build. The jsp page
loads fine until it comes to the first taglib tag, and then the error
occurs. Any suggestions? Thanks.

You can get an IllegalStateException when you attempt to grab the output
stream after something else has written to it.

For example if you use jsp:include, the outer jsp has already called
getWriter()
on the response object, the inner jsp will get an IllegalStateException if
it
calls getOutputStream() on the same response object.
