method flushBuffer()V not found

[Constelix - Web Developers' Community]

Hi, when I try any of the examples included in %TOMCAT_HOME%/webapps/examples/jsp/index.html, my browser reports:   javax.servlet.ServletException: javax.servlet.ServletResponse: method flushBuffer()V not found   at... a lot of components and methods of the JSP pages   I have even downloaded and installed Tomcat again, but the problems stays the same.   Does anyone know why this happens, and what I should do?   Thank you very much, and best regards.   Luis Rosso
