javax.servlet.ServletResponse: method flushBuffer()V not found

[Nicol�s Mart�n]

I have a problem executing JSP examples after the installation of
TOMCAT.
Everytime I get this message:

Error: 500
Location: /examples/jsp/anydirexample/anyJSP.jsp
javax.servlet.ServletResponse: method flushBuffer()V not found

Somebody can help me?
Thanks.

Nico.
