Then, this is the cool part. In your shell profile, set an alias to:
emacs='/Applications/Emacs.app/Contents/MacOS/Emacs --insert'Now type emacs myfilename on a command line and it will start it up like an Xemacs session :-) woohoo. Good news is that JDE also works fine with Emacs on Aqua.

[Editor's note: I tried building from source, and although the application compiled fine, it quit unexpectedly on launch, so I was unable to test the alias portion of the tip. I've been using Carbon Emacs which seems to work fine.]
