Hello Soumik,
just curious:
1) What happens if you change your implementation to:
@Post("xml")
public Representation create(final XmlRepresentation xml) {
System.out.println("XML received:\n" + xml.getText());
return null; // Just for completeness of this example implementation
}
Do you see the XML printed?
Beware with streamed representations, they may be consumed by some
method calls, thus you don't have them available anymore after such
consumption happened (probably getAvailableSize() is consuming it
somehow... I don't know)
BTW, with the annotation on the above example, you don't need to check
the media type of the provided representation, that handler will only
be called when XML is POSTed.
2) HTTP already defines a code for 'unsupported media type': it's HTTP
code 415, Status.CLIENT_ERROR_UNSUPPORTED_MEDIA_TYPE. Unless you have
very good reasons not to, try to use the standard HTTP codes on your
REST API implementation responses.
Hope this helps, good luck!
