Subject: RE: CXF and optional entity parameters
Hey Sergey,
I'm using the version 2.3.8.
I'm going to check what I can do with JAXBElementProvider.
Note: if I could add something like @Nullable on my parameter, it will
be perfect :)
Cheers,
Anthony

Hello,
I did not find the answer of this issue.
Everything works perfectly when "entity" (a JAXB pojo) is not null.
@Path("/")
public class myClass {
@PUT
@Path("/{p1}/something/{p2}/something/{p3}/something/{p4}")
@Consumes(MediaType.APPLICATION_XML)
Response updateStuff(
@PathParam("p1") String p1,
@PathParam("p2") Long p2,
@PathParam("p3") String p3,
@PathParam("p4") Long p4,
MyEntity entity);
}
But if I do not send anything about "entity" (because it is
optional), I received the bellow error.
JAX-RS 1.1 requires 400 returned in cases where an empty payload is
presented to JAXB providers, which CXF version are you working with ?
Is it 2.3.7 ? I'm seeing JAXBElementProvider checking on Content-Length
header, can you please register a LoggingInInterceptor or capture the
request with the tcp trace utility and let me know if Content-Length is
available ?
Please can you help me to fix?
If you do expect 'null' then the best thing to do is to register a
custom JAXBElementProvider which overrides readFrom(...) and return null
if the request is empty, the protected getContext() returning CXF
MessageContext will help...
Let me know please if you need more info...
Sergey
