I’m trying to write a web service for the java.util.logging api. So I wrote a class MyLogRecord that inherits from LogRecord. I annotated this class with JAX-B annotations, including @XmlAccessorType(XmlAccessType.NONE) so it would ignore non-annotated fields and properties. When I start up tomcat, I get errors that java.util.logging.Level and other java.util.logging classes do not have a default constructor, but none of my annotated methods make any reference to the Level class or any of the other java.util.logging classes. These are referenced by the parent class.

My sub-class has everything it needs defined. How can I get JAX-B to ignore the parent class completely?

Update: I found another post on this, which suggests modifying the parent class. This is obviously not possible because I am extending a java.util class. IS there any way to do this without modifying the superclass?

Update2: I found a thread on java.net for a similar problem. That thread resulted in an enhancement request, which was marked as a duplicate of another issue, which resulted in the @XmlTransient annotation. The comments on these bug reports lead me to believe this is impossible in the current spec.

    You need to mark the parent class @XmlTransient. Since the parent class is in the JRE and cannot be modified by you, you need an alternate mechanism.

    The EclipseLink JAXB (MOXy) implementation offers a means of representing the metadata as XML that you could use:

    http://wiki.eclipse.org/EclipseLink/Examples/MOXy/EclipseLink-OXM.XML

    You can specify some of the metadata using annotations, and the rest as XML. Below is what your document would look like:

    <java-types> 

    <java-type name="java.util.logging.LogRecord" xml-transient="true"/>

</java-types>
