JAX-WS, why LinkedHashMap collection received is empty?

问题

I am building a java webservice which receive a LinkedHashMap as argument. The LinkedHashMap collection has some elements inserted in the client side, but I received it empty in the webservice.

回答1:

Avoid returning collections directly. Instead of returning a List<X>, return a JavaBean that has a List<X> in it. This will give you more detailed control over the marshalling anyway.
