I've tracked the problem down to a particular method signature:
@GET @Path("/foo") FooResult
previewLayoutGroupToLocationAssignment(@QueryParam("") Foo foo);
where Foo is:
public class Foo extends com.foo.FooTO { ... }
and FooTO is generated by JAXB:
@XmlType(name = "", propOrder = {
...
})
@XmlRootElement(name = "foo")
public class LayoutGroupAssignment
implements Equals, HashCode, ToString
{
@XmlElement(type = Long.class)
protected List<Long> a;
@XmlElement(required = true, type = String.class)
@XmlJavaTypeAdapter(Adapter1 .class)
@XmlSchemaType(name = "date")
protected DateTime b;
@XmlElement(required = true, type = String.class)
@XmlJavaTypeAdapter(Adapter1 .class)
@XmlSchemaType(name = "date")
protected DateTime c;
...
}
I refer to the XSD in the jaxrs:schemaLocations section of my application
context and I configure the WadlGenerator in the jaxrs:providers section as
follows:
<jaxrs:providers>
<bean class="org.apache.cxf.jaxrs.model.wadl.WadlGenerator">
<property name="applicationTitle" value="FooService"/>
<property name="singleResourceMultipleMethods" value="false"/>
<property name="addResourceAndMethodIds" value="true"/>
</bean>
</jaxrs:providers>
