I have done it like this:

```auto
Query<Record2<UUID, String>> query = Query.buildNativeQuery("select e/ehr_id/value, o/data[at0001]/events[at0002]/data[at0003]/items[at0004]/value/defining_code/code_string from EHR e contains COMPOSITION a [openEHR-EHR-COMPOSITION.externalterm.v0] contains OBSERVATION o [openEHR-EHR-OBSERVATION.externalterm.v0]", UUID.class, String.class);`
List<Record2<UUID, String>> result = openEhrClient.aqlEndpoint().execute(query);
result.forEach(res->{System.out.println(res.value1() + " "+ res.value2());});

```
