Maybe I'm not reading carefully enough (and I haven't had time to trace the
code) but I don't understand what you mean in your "modifications".

The correct behavior seems to me that when a file is included, a 'fake'
JspReader should be created to scan the file for a @page directive with a
contentType, then create the 'real' JspReader using either the @page
directive if it was found, or the encoding of the including file as a

You may be already saying what I just said, and I hope you are :-)  Hans'
replies have confused me(!), because they don't really seem to apply to this
