Hi, thanks for the reply.
1) I mean if I try to send the response like this:
-----------------------
PrintWriter pw = response.getWriter();
pw.write("<html><body>Error!</body></html>");
pw.close();
-----------------------
it works OK and I see an "Error!" message on the client side.
2) If I use sendError() method instead, I don't see anything - just an
empty page.
3) This happens ONLY if the request was forwarded to ErrorHandler
servlet by Tomcat in case of an error or exception:
-----------------------
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/ErrorHandler</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/ErrorHandler</location>
</error-page>
-----------------------
If, for example, I request ErrorHandler directly by URL, I can see an
error page.
So I wonder why this happens: is it a bug or my misunderstanding of
sendError() method?
