Hey Seth,
Did you push your changes to sf.net? Into which branch? I pushed Melania's
support for controller annotations to master on sf.net on 7/22 along with the
conversion of element/service.jsp (commit
3b378424bcb15de58359669ce09fde51ce91152f). I want to make sure we aren't
stepping on each other's toes and that we try to keep things synced between
different branches except when it doesn't make sense. Also, since Melania is
converting JSPs and servlets to use Hibernate, I want to make sure we aren't
stepping on each others toes there, either.
