Hi,
I couldn't investigate this issue until today, but I found the reason
to this problem.
Basically I am generating my classes from the WSDL using the
cxf-codegen-plugin. In my jaxb bindings I was using <xjc:simple> to
generate nice method names for the generated classes.
However, changing the methods names did affect the ability to choose
the correct accessors in the org.apache.cxf.jaxb.JAXBUtils class.
For example, I had a list of a complex some object called "dbRef":
<xs:complexType name="dbRefListRequest">
<xs:sequence>
<xs:element name="dbRefList" type="psq:dbRefList"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="dbRefList">
<xs:sequence>
<xs:element maxOccurs="unbounded" name="dbRef"
type="psq:dbRef"/>
</xs:sequence>
</xs:complexType>
The generator was creating a class that used this list, where the
accessor methods had the funny name "getDbReves" or "setDbReves" (of
couse, the plural of dbRef is dbReves? :))
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "getByInteractionList", propOrder = {
"dbReves",
"infoRequest"
})
public class GetByInteractionList {
@XmlElement(name="dbRef", required = true)
protected List<DbRef> dbReves;
...
And then those accessors were not found.
Removing the <xjc:simple> fixes the issue, but I have lost the "nice"
plurals, which I can live with.
Bug or feature?
Thanks,
Bruno
