Hi,

I have some problem validating my JSP page.  It says:

>Sorry! A fatal error occurred when attempting to
>transcode the character encoding of the document.
>Either we do not support this character encoding
>yet, or you have specified a non-existent character
>encoding (often a misspelling). 
>The detected character encoding was "8859_1".
>The error was "8859_1 undefined; replace by
>iso-8859-1".

although the document says:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
     <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
     <title>menu page</title>
....

If I use Opera to validate the same page via "Frame/Validate source" it has no problem validating.
This is likely due to the fact that Opera validates the cached version of the page, which has the same source code, but a different name ("something.htm" instead of "menu.jsp").

How can I validate my JSP pages? The contents received by the browser is pure html, but I am forced to give the files names that end in ".jsp" so the server can parse them and generate the html content.
It seems like this is a validator bug.

Thanks in advance for any help.
