Hi,
You need to wrap the type around a GenericEntity instance to preserve
the type information:
https://jsr311.dev.java.net/nonav/javadoc/javax/ws/rs/core/GenericEntity.html
Otherwise if you are just returning Response.ok(...).build() you can
declare the entity type as the return type of the resource method.
Note that Jersey will derive a root element name of the list from the
class of the item (currently it is not possible to configure this name).
On the client side you need to use:
https://jersey.dev.java.net/nonav/apidocs/latest/jersey/com/sun/jersey/api/client/GenericType.html
Note that we made a big mistake in the EG because we tried and failed
to make Response generic (but subsequently we now have worked out how
to do that).
Paul.
