In EPractice Lab, there is a question "which of the following statements are true about MessageBodyReader?"
a. contract for a provider that supports the conversion of a stream to a Java type
b. contract for a provider that supports the conversion of a XML to a Java type
c. To add a messageBodyReader implementation, annotate the implementation class with a @Provider
d. To add a MessageBodyReader implementation, annotate the implementation class with @MessageBodyReader
I think the correct choices are a, b and c.
But the given answers are only a and c.
I think b is correct because in JAX-RS, we can provide our own customized MessageBodyReader to read an object into XML or Jersey provides a standard entity provider that can read Source/Document/JAXBElement into XML.
