The JBossWS-CXF implementation of WSConsume tool ignores the -t (target) option and simply relies on the available JAXWS api level.
However Apache CXF comes with a -frontend jaxws21 option that allows generating jaxws 2.1 code even if jaxws 2.2 apis are available. That flag is currently not passed to the underlying cxf tools, so the valid request of generating 2.1 level code is ignored.
