Well, what do mean by that, what do you expect?
I find both <http://jseditor.sf.net/> and <http://myeclipseide.com/>
sufficient in that matter. See <news:>.
BTW: I could not reach Harish Kataria regarding his JavaScript editor
(which has no code completion but is great in recognizing prototypes),
both contact addresses bounce. Do you think he would mind if I allowed
downloading version 2.0 of it from my Web site?

Me too

But that does not really matter, Java is cross-platform,
thus so is Eclipse and are (almost all) Eclipse plugins.
