>>From section 5.5 of the JAX-RPC spec.
A JAX-RPC value type is a Java class whose value can be moved between a
service
client and service endpoint. A Java class must follow these rules to be a
JAX-RPC
conformant value type:
. Java class must have a public default constructor.
. Java class must not implement (directly or indirectly) the java.rmi.Remote
interface.
. Java class may implement any Java interface (except the java.rmi.Remote
interface)
or extend another Java class.
. Java class may contain public, private, protected, package-level fields.
The Java type
of a public field must be a supported JAX-RPC type as specified in the
section 5.1,
"JAX-RPC Supported Java Types".
. Java class may contain methods. There are no specified restrictions on the
nature of
these methods. Refer to the later rule about the JavaBeans properties.
. Java class may contain static or transient fields.
. Java class for a JAX-RPC value type may be designed as a JavaBeans class.
In this
case, the bean properties (as defined by the JavaBeans introspection) are
required to
follow the JavaBeans design pattern of setter and getter methods. The Java
type of a
bean property must be a supported JAX-RPC type as specified in the section
5.1,
"JAX-RPC Supported Java Types".
Even though the spec allows value types with public fields I think the
JAX-RPC reference implementation only supports JavaBeans right now. This
means implementing (not extending) java.io.Serializable, having a public
no-arg constructor and having public getter/setter methods for each of the
fields to be [de]serialized.
