Which Java SOAP XML object serialization library would you recommend for Java object exchange with other platforms / languages (.NET, Delphi)?

I think you have answered your own question.
XStream (outputting as JSON) is a nice clean solution. If you alias types you get a clean output format. After that it doesn't matter which SOAP stack you use so long as it is nice and interoperable with Delphi/.NET.
