Thanks Sergey, your tip is working perfectly.
nice, thanks, by the way, I wonder how does HttpServletRequest determine
the length <= 0, right now JAXBElementProvider checks 'Content-Length',
do you have it in the lower case format coming in ?
Can you please add the org.apache.cxf.interceptor.LoggingInInterceptor,
using the "jaxrs.inInterceptors" servlet parameter if using
CXFNonSpringJaxrsServlet ?
I was a bit cautious about using InputStream.available() - it does not
seem to guarantee the data are not actually available if if it returns 0.
Re Nillable - I guess that can be done - it is the default for all the
providers (if no body is available) except JAXB
Thanks, Sergey

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
