I'm not sure what else I can tell you. If you read the servlet specification, it says how you can use either getOutputStream() or getWriter() to write the content. We need to capture both of these to actually get the content (as we don't know which one will be called).
What specific questions do you have?

Scott,
Could you please give an example of when this issue arises? I need a bit more explanation to understand when this is a problem.
Cheers,
John.

John,
Different servlet containers call getWriter() and getOutputStream(). It depends on their underlying implementation of servlets / JSPs.
You need to include them both to work on all servlet containers.

Thanks Scott,
Is this so that they can both be called to write both binary data and
char
data. If so, under what circumstances is this required?
Thanks,
John.

John,
This is still required. The servlet spec says that the end user can call getOutputStream() or getWriter(). This wrapper needs to capture
both.
Feel free to ask questions like this on the mailing list.
Try to write this test first if you can. Are you familiar with writing unit tests?
Cheers, Scott

Hi Scott,
I am looking at moving the include tag from WW1.3 to WW2.
Looking at the source for the WW1.3 Include tag I can see that it uses a wrapper for the ServletResponse. The comments say:
* Simple wrapper to HTTPServletResponse that will allow getWriter()
* and getResponse() to be called as many times as needed without
* causing conflicts.
* <p>
* The underlying outputStream is a wrapper around
* [EMAIL PROTECTED] webwork.view.taglib.PageOutputStream} which will store
* the written content to a buffer.
* <p>
* This buffer can later be retrieved by calling [EMAIL PROTECTED] #getContent}.
Why is this necissary and do you think it is still necissary in WW2.
Thanks,
John.
