Paul,
If you read the JSP spec, it clearly states that if
any output as been flushed from the page to the response
output stream of the underlying Servlet that this operation
shall fail.
I dont know the circumstances of your particular JSP but I
suspect that it may be structured such that by the time you are
attempting the forward that it is too late in the process.
Unfortunately this is a semantic associated with the Servlet
layer that we cannot avoid in some circumstances.
Ensuring that your JSP buffer size is sufficiently large to
avoid the JspWriter from flushing to the output stream will
avoid this.

P.S
Now that I come to think of it, this could be a limitation
of the current RI that we are working to resolve.
