Or simply have two ParamConverters, one for individual bean properties,
and one for the bean itself, create it in the converter, parse the date
and set it on the bean

Hi
You def do not need to send the code all the time, most of this code is
not relevant.
What happens is that in some cases you rely on the CXF extension where
you have something like
@MatrixParam("") MyBean
In this case MyBean properties represent individual Matrix parameters
and such properties may be converted with the help of the converters.
Note in this case the runtime itself deals with the instantiation of
MyBean and injecting matrix parameters into it.
When you have
@PathParam MyBean
it means you expect a single path parameter value converted into MyBean
as opposed to to one of MyBean properties.
Perhaps, in your case, you may want to do @BeanParam MyBean and have the
individual MyBean property annotated with @PathParam, etc

Right, may be a bit of extra code is pasted here :-), not easy to see
the relevant bits...
You have GetUserByDateRangeRequest2 but expect a Date converter be
called so of course that won't work.
Please tell, what should be done to make Date converter to be called
when using PathParam passing an object containing a java.util.Date
object.
Of course, when using MatrixParam, passing GetUserByDateRangeRequest
object, custom ParamConverter SomeDateConverter is correctly getting
invoked.
Thanks much again
