Which Java SOAP XML object serialization library would you recommend for Java object exchange with other platforms / languages (.NET, Delphi)?
Commu
I would recommend CXF. It is a very good services stack and includes JAXB data binding and JAX-WS support. You may want to look at an open source integration platform like Mule that includes CXF (also supports Axis and XStream) if you need more advanced transformation and routing of your messages. It is lightweight and can be embedded or run without an app server.
