Hi all,
In EclipseLink OXM we currently have the ability to specify the Java
type of an element, attribute, etc., but there is no way to specify
what Collection type (if any) is being used. For example, the
following is currently supported:
Java: private java.lang.Integer zipCode;
OXM: <xml-element java-attribute="zipCode" type="java.lang.Integer"/>
But the following is not:
Java: private java.util.List<java.lang.Integer> zipCodes;
This is needed for Dynamic JAXB -- because there is no Java class
behind the scenes, we must depend exclusively on the OXM for all of the
necessary information in order to build the dynamic type.
Dave M has put together a wiki page for this issue at:
http://wiki.eclipse.org/EclipseLink/DesignDocs/322284
I think the only real point of contention would be what we call this
attribute. JPA uses "
attribute-type", but we feel this would
be confusing as we already have an attribute called "
type". I
would propose that we add a "
collection-type" attribute to the
following OXM tags:
<xml-element>
<xml-elements>
<xml-any-element>
e.g.
<xml-element java-attribute="zipCodes" type="java.lang.Integer" collection-type="java.util.List"/>
Thoughts?
