public @interface XmlReadOnly
Purpose: This annotation indicates that a specific property should be flagged as read-only by EclipseLink. The value for this property will never be written out to XML during a marshal if flagged as read-only.
Example:
@XmlRootElement(name="customer")
public class Customer {
...
@XmlElement
@XmlReadOnly
public String firstName
...
}
