There are a number of rules, see here:
https://jersey.dev.java.net/documentation/1.1.1-ea/user-
guide.html#d4e147
Jersey also allows extensions to the rules using StringReader/Provider:
https://jersey.dev.java.net/nonav/apidocs/1.1.1-ea/jersey/com/sun/jersey/spi/StringReader.html
https://jersey.dev.java.net/nonav/apidocs/1.1.1-ea/jersey/com/sun/jersey/spi/StringReaderProvider.html
What Felipe really wants is Jersey to resolve a type variable, T say,
to the concrete type, String say, declared by an extending class.
Currently Jersey only resolves type variables for request entities. I
need to modify the underlying class model that Jersey utilizes so that
it resolves all type variables for parameters of constructors/methods
and fields (and in addition log warnings or errors if a type variable
cannot be resolved).
