Thanks alot Günther for sticking with me on this, much appreciated.
Well it seems I can either use jibx with axis2 web services or
Marshall outside of it - not both yet. Please see my comments inline:

Seemingly you can either have type-name OR name but not both. I tried
pretty hard via my custom.xml that I pass to jibx2wsdl to not make the
mapping abstract, including map-abstract=false. No luck though.

BindingDirectory.getFactory is pretty confusing to me in that
"binding" is the name attribute of the binding element and not a
filename, just "binding" has other references in the classloader
somewhere, I seemingly can't customize the generated binding name, and
there's no public method to find a list from BindingDirectory what
names are lurking in its list and where they came from. Probably good
reasons for all that, I'm just a newbie.
Anyways, I tried the above code without it being abstract, and while
it works, I need something that can both work with axis2 and outside
of it - the latter I mean by uploading an xml file from the file
system or browser and marshalling it with a type-name and being
abstract. I'm looking at the axis2 code gen for my original binding to
see if I can tweak it to work without a soap message.
Any ideas on how to get marshalling to work with type-name and not
just name? I'm going thru axis2 codegen / jibx source and unit tests
to see I can solve this.
Thanks!
