After some testing (by editing the code generated by cxf-codegen-plugin) it turns out that its not the missing @XmlElement that causes my problem but the missing @XmlRootElement.
Since the XML I'm trying to unmarshal is not a root element, no @XmlRootElement is generated (which I assume is as it should be). If I manually add the following: *@XmlRootElement(name = "logEntries", namespace = " http://www.digia.se/wsdl/cws/v2";)* then the unmarshalling works. How can I unmarshal a subtree (fragment) using JaxB? Is *@*XmlRootElement(name required? /Bengt 2012/8/1 Bengt Rodehav <be...@rodehav.com> > I have been using cxf-codegen-plugin to generate java code from wsdl.
