While upgrading jsf version from 1.2 to Jboss7.1 module version, I am getting strange exception. I couldn't figure what could be causing this.
(http--127.0.0.1-8080-1) Servlet.service() for servlet Faces Servlet threw exception: java.lang.IllegalStateException: Header count exceeded allowed maximum: 128
Attached complete log. Any pointers would be really appreciated.
I got same error.
But i created new "JSF2" project and i tried to keep ".jsf" extension for backward compatibility.
In my case error is found into the web.xml:
Must be .xhtml in any way.
