unfortunately, that method is only available in servlet 2.3, and cocoon still ships with 2.2 in lib/core (and 2.3 in lib/optional)
is it planned to move to servlet 2.3?
the presence of the 2.3 lib and the 2.3 doctype in web.xml seem to indicate it. compiling with servlet 2.3 didn't cause problems for me, and any reasonably recent servlet container already runs cocoon under 2.3 anyway.
