public record Link(String text, String uri) {}

can be serialized with JSON-B into a JSON array:

import org.junit.jupiter.api.Test;
import java.util.Set;
import javax.json.bind.Jsonb;
import javax.json.bind.JsonbBuilder;

public class JSONBTest {

    @Test
    public void serialize() {
        var links = Set.of(new Link("json-b", "http://json-b.net"),
                            new Link("jakarta ee", "https://jakarta.ee"),
                            new Link("microprofile", "https://microprofile.io"));
        Jsonb jsonb = JsonbBuilder.create();
        var jsonArray = jsonb.toJson(links);
        System.out.println(jsonArray);
    }
}

The code above generates the following output:
