Subject: Re: JAXB and JAX-RS under CXF

Oh great thing Sergey,

thanks for that answer. I just tried and it works just fine. In fact, documentation was either
misleading or I misread. The 
documentation says

"This property has a limited value for JAXRS services as JAXB is supported by default, the
only supported value is 'aegis' and it is 
a shortcut for registering an Aegis provider [...]"

which is a little hard to understand. One the one hand it says JAXB is supported, but on the
other hand 'aegis' is the only value 
you're allowed to use. So this confused me.

JAXB will be supported with or without "" but I'll look
into simplifying the documentation and 
enhancing a bit the way this property is handled...

thanks, Sergey

Thanks for the clarification and the impressively fast response!
