Hi Sergey,
I do not understand your solution. My exception mapper is like the
following:
public class MyExceptionMapper extends ExceptionMapper<Throwable>
{
public Response toResponse(Throwable throwable) {
if (the throwable comes from a matched method provide
application/json)
map throwable to json
else if (.... provide text/html)
map throwable to html
....
}
}
Where should put the HttpHeaders in MyExceptionMapper?
Regards,
Rice
