text
Body
copied!<p>I try to use <code>Google App Engine</code> with <code>Jaxb2Marshaller</code> I have the following code:</p> <pre><code>@Entity @XmlRootElement public class Incident { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Key incidentId; </code></pre> <p>I tried to use <code>@XmlJavaTypeAdapter</code> annotation with my specific adapter or <code>@XMLTransiet</code> to simply skip this field but I'm still getting the following error message. How can I solve this?</p> <pre><code>org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'appView' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]: Cannot resolve reference to bean 'jaxbMarshaller' while setting constructor argument;
