As I have already said, return Response with the error code only.
Returning null indicates to the runtime that the mapping has not been
done in which case it has to rethrow the original exception.
If returning a response with the code only does not help then move to
the alternative 2 (write your own MessageBodyWriter which will
internally delegate to Jackson MessageBodyWriter - it will be loaded
inside your custom MBW, and register it instead of Jackson with the
endpoint).
If that does not work - move to the alternative 3. Introduce
AsyncResponse first into your code (see for ex AsyncResponse package
docs), and then once you have it, you will be able to register the
callback with this AsyncResponse

It comes here on exception mapper :
public class GTMClientExceptionMapper implements
ExceptionMapper<IOException> {
public Response toResponse(IOException ce) {
// ErrorMessage errorMessage = new
ErrorMessage(ce.getMessage(),400,"Exmaple Message ");
return null;
// return Response.status(Response.Status.NOT_FOUND)
// .header("Content-Type", "application/json")
// .build();
}
}
I tried to various stuff, but still throw the error, any guess here ?

Well, first thing to check is whether this mapper is invoked, note it is
not auto-discovered by default, unless you explicitly enable the
auto-discovery, so it needs to be registered in jaxrs:providers.
But even if it is invoked, the problem is you still try to return some
error message - the runtime will again attempt to write it to the output
stream which is already terminated.
So make sure it is invoked, then make Throwable more specific and finally,
do not set an entity on Response

Sergey,
I tried using to write Exception Mapper :
1.Here MapperException - > IOException, ClientErrorException
public class GTMClientExceptionMapper implements
ExceptionMapper<MapperException > {
public Response toResponse(IOException ce) {
ErrorMessage errorMessage = new
ErrorMessage(ce.getMessage(),400,"Example : XYZ");
return Response.status(Response.Status.NOT_FOUND)
.header("Content-Type", "application/json")
.entity(errorMessage)
.build();
}
}
But it doesn't work, other exception mapper stuff is working ?
May you please tell me If there is something else I supposed to do ? :
JAXRSOutInterceptor.handleWriteException
2. Suggest me one example of this : Another option to try is to wrap
Jackson with a custom JAX-RS MessageBoryWriter and handle the write
exception there.
3.May you suggest any example of this :
Finally, when working with AsyncResponse is used, one might want to
register
https://jax-rs-spec.java.net/nonav/2.0-rev-a/apidocs/javax/ws/rs/container/ConnectionCallback.html

Hi
JAXRSOutInterceptor.handleWriteException checks JAX-RS ExceptionMapper
so
perhaps you can intercept that Exception and return Response with the
code
only from this exception mapper.

MessageBoryWriter and handle the write exception there.

Hi All,
I have made a web application, which uses Apache CXF on backend. In
many
situation - Client(user) uses the web application to fetch some data
to
view ( say click on button) which CXF web service provide from the
backend, But Client closes the browser, however the cxf web service
was
busy to bring the data. So on logs it shows : ClientAbortException.
This
behaviour is correct. Its fine.
But I need the help on following :
Is there any way to catch such exception in the CXF webservice code
and
logs the customized error message, rather showing complete logs( as
below)
? If Client has aborted the connection then is there any way to handle
such
situation and act accordingly?
