JAXB XmlAdapter with @Inject

DiFrango, Ronald (CONT)
All,

We recently upgraded from:

<eclipse.persistence.core.version>2.5.2</eclipse.persistence.core.version>
<jersey2.version>2.17</jersey2.version>
<hk2.version>2.4.0-b10</hk2.version>

to:

<eclipse.persistence.core.version>2.6.1</eclipse.persistence.core.version>
<jersey2.version>2.22.1</jersey2.version>
<hk2.version>2.4.0-b34</hk2.version>

I’m not sure if this is a Jersey, Moxy, or HK2 issue, but I’m going to try to explain what we have:

@XmlJavaTypeAdapter(A.MyXmlAdapter.class)
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class A {
   @Named
    public static class MyXmlAdapter extends XmlAdapter<String, ReferenceId> {
        @Inject
        private MyService service;

        @Override
        public A unmarshal(String value) throws Exception {
            return service.convertToA(value);
        }

        @Override
        public String marshal(A a) throws Exception {
            return service.convertToString(value);
        }
    }
}

Now on my resource if I declare it as t

public A createOne(A a) {
        return a;
}

The service != null on MyXmlAdapter so it works

Another variation that also works is:

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({A.class})
public class B {
   private List<A> entries;
   
   public List<A> getEntries() {
        return entries;
    }
}

But if I declare the type as of list:

 public A createOne(List<A> a) {
        return a;
}

service == null on MyXmlAdapter so it fails.

Thanks,

Ron DiFrango
