Subject: Re: JAXB and JAX-RS under CXF
Thanks Sergey,
just one more question. I converted a plain (non-OSGi) JAX-RS project to DOSGi-based CXF. Now, for some of my JAXB annotated classes
I get the error message:
com.sun.istack.internal.SAXException2: unable to marshal type "a.b.c.X" as an element because it is missing an @XmlRootElement
annotation
S.B : Do those objects actually have @XmlRootElement ?
I use Pax Exam to set up a test case that marshalls the object to a byte[] and
unmarshalls it afterwards from it.
Do you know that error?
S.B : yes, usually it is to do with @XmlRootElement being not present or, in OSGI case, being 'lost' at runtime, due to a missing
import package value...You can condigure DOSGI RI to not require @XmlRootElement for JAXRS services...
Why is CXF behaving different than "plain" JAXB?
S.B : what exactly is different ?
Is it using a different JAXB implementation at all? And if yes, is it possible
to switch to the implementation included in the JVM?
Kind regards,
Daniel

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.
S.B : it kind of does not makse sense, now that I read it again. (CXF) JAXRS do not use (CXF)databindings as often as they use
'providers', technically both terms are probably identical, but I wanted to not require users to set this property given that
they will probably want to register say a DataBindingProvider provider delegating to CXF Aegis as OSGI service, with some custom
configuration, etc...That said, for simple cases, letting users just to do "org.apache.cxf.rs.databinding=atom" would also make
sense...
JAXB will be supported with or without "org.apache.cxf.rs.databinding=jaxb" but I'll look into simplifying the documentation and
enhancing a bit the way this org.apache.cxf.rs.databinding property is handled...
thanks, Sergey
Thanks for the clarification and the impressively fast response!
Regards,
Daniel

Hi
It is possible. It has to work, you do not even has to enable it for JAXRS; for DOSGI-RI/JAX-RS it is a default databinding given
that the JAXRS spec requires the JAXB support OTB so I thought asking users to explictly add org.apache.cxf.rs.databinding=jaxb
just to enable JAXB would be too much...
Are you seeing any issues ? I'm thinking may be I've just done another piece of the documentation which is confusing ? One thing
I'm saying there is that if you do not want to have your bundle modified for JAXB be supported at runtime as well as to
explicitly annotate beans with @XmlRootElement and friends (that is, to import JAXB packages) then if it is JAX-RS only you can
register a custom (CXF JAXRS) JAXBElementProvider and tell it to use JAXBElement internally and that is it...
cheers, Sergey

Hi list,
following the DOSGi reference [1] I see that it's not possible to use JAXB under JAX-RS but with JAX-WS. Is that correct? And
what is the reason for it?
Kind regards,
Daniel
