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

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? Why is CXF behaving different than "plain" JAXB? =
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
