CXF (or JAX-WS?) generating wrong SOAP XML request

First of all, apologize not to provide sample source code. Working in a
project with some sensitivity about Internet DLs and groups.

Question. Did you ever get a wrong SOAP XML request even if it was
automatically generated?

I'm having that problem. SOAPUI manages to work just fine, but wsimport or
wsdl2java don't.

2nd question, to fix that, I'm manually updating the generated class
ObjectFactory, where the _*_QNAME are defined, and changing the namespace
and/or name to what is expected. Is this safe or I'm just giving pain
killers to the patience rather than healing it?

Working with CXF 2.7.11, JAX-WS 2.2, Java 7.

Thank you!
