Hi Sergey,
First of all thanks for answering because I am banging my head against
the wall for 3 days now with this to the point that all my google
searches have turned pink (page already visited).
If I understood correctly you are telling me that I need
ParamConverterProvider
http://docs.oracle.com/javaee/7/api/javax/ws/rs/ext/ParamConverterProvider.html
I suppose I can do that and I hope I will be able to register it through
the web.xml (I am using nonspringservlet). The documentation is a bit
sparse but I believe I will manage it.
What I need to understand is the following
JAX-RS MessageBodyReader is not involved into reading individual
parameters, it can only handle a method parameter representing a
complete HTML request body, i.e. the parameters without JAX-RS
annotations like PathParam, HeaderParam or FormParam.
Qustions:
1) If I don't use @FormParam or POST: Do I still need to have my own
ParamConverterProvider? or it will be handled automatically by CXF?
2) Or do you mean I must tag it like this @FormParam("") since only one
parameter can be in the post form (body) ?
3) I have to create a ParamConverterProvider for all my custom objects?
4) What is missing and CXF cannot do it automagically like it does it
with aegis and SOAP given that the outgoing Entity (return value )
through JAX-RS is working all right.
Any links for further reading on this you may have are much appreciated.
Again thanks for your help.

Hi,
My problem looks like this
http://mail-archives.apache.org/mod_mbox/cxf-users/201307.mbox/%[email protected]%3E
I am using cxf 3.0.0 so I believe the thread does not apply and I am not
sure what I should do or try based on that thread.
My problem is that I am trying to call
@POST
@Path("existing-entity")
@Consumes("application/x-www-form-urlencoded")
public Entity getExistingEntity(
@FormParam("entity") Entity entity)
throws SQLException;
with an entity and the service is instantiating the Entity based on
String constructor which looks like a fallback CXF strategy around
./rt/frontend/jaxrs/src/main/java/org/apache/cxf/jaxrs/utils/InjectionUtils.java:393
The jackson provider is not called to do the deserialization. I don't
know why. Similarly as the link I provide above if I pass the json
payload that the client is sending to objectMapper.getValue(json,
Entity.class) everything works correctly.
So the question is why jackson is not involved during deserialization?.

You need to register JAX-RS 2.0 ParamConverterProvider for Entity which
will use Jackson mapper to convert a given String value into Entity
HTH, Sergey
It works fine for serialization.
My guess the fail is in somewhere around InjectionUtils.java:358
Object result = createFromParameterHandler(value, pClass,
paramAnns, message);
if (result != null) {
return pClass.cast(result);
}
but I don't know enough to debug this.
