how to set a pojo as a moxy?

Question

I have this file:

@XmlRootElement(name="Projects")
public class Projects extends ResponseWrapper {
    private ArrayList<Project> project;
    @XmlElement(name="Project")
    public ArrayList<Project> getProject() {
        return project;
    }

    public void setProject(List<Project> list) {
        this.project = (ArrayList<Project>)list;
    }

}

Project has an @XMLInverseReference

  System.out.println(JAXBContext.newInstance(Projects.class).getClass()); //error

Exception Description: The method [setProject] or [getProject] is not defined in the object [com.tps.www.data.Projects].

While printing out Project.class:

 System.out.println(JAXBContext.newInstance(Project.class).getClass()); //OK
20:27:01,118 INFO  [stdout] (http-localhost-127.0.0.1-8180-1) class org.eclipse.persistence.jaxb.JAXBContext

Note: I'm the EclipseLink JAXB (MOXy) lead and a member of the JAXB (JSR-22) expert group.

I have not been able to reproduce the issue you are seeing. Could you help provide more information so that I can reproduce the problem? Here is what I have tried:

1. Removed JPA & Hibernate annotations from Project class to get it to compile.
2. Created empty ResponseWrapper class for Project and Projects to extend.
3. Created classes for each class referenced by Project.

4. When a property is marked with @XmlInverseReference added the project property on the corresponding type:

   public class Contract {
   
       private Project project;
   
       public Project getProject() {
           return project;
       }
   
       public void setProject(Project project) {
           this.project = project;
       }
   
   }
   

5. Ran the following demo code:

   import java.io.File;
   import javax.xml.bind.*;
   
   public class Demo {
   
       public static void main(String[] args) throws Exception {
           JAXBContext jc = JAXBContext.newInstance(Projects.class);
   
           Unmarshaller unmarshaller = jc.createUnmarshaller();
           File xml = new File("src/forum19953731/input.xml");
           Projects projects = (Projects) unmarshaller.unmarshal(xml);
       }
   
   }
