net.sf.jasperreports.engine.JRException: Error retrieving field value from bean: fullname. When using NativeQuery

Getting:

net.sf.jasperreports.engine.JRException: Error retrieving field value from bean: fullname.

Only when using NativeQuery in Hibernate with JasperReports.

When I use JPA criteria query then there's no issue

JPA Criteria

try (Session session = sessionFactory.openSession()) {
    CriteriaBuilder criteriaBuilder = session.getCriteriaBuilder();
    CriteriaQuery Client criteriaQuery = criteriaBuilder.createQuery(Client.class);
    Root root = criteriaQuery.from(Client.class);
    criteriaQuery.where(criteriaBuilder.equal(root.get("id"), id));
    return session.createQuery(criteriaQuery).getResultList();
}

But when I use NativeQuery I face
net.sf.jasperreports.engine.JRException: Error retrieving field value from bean: fullname.

<b>Native Query :</b>

try (Session session = sessionFactory.openSession()) {
    List<Client> query = session.createNativeQuery("select c.*, p.*
        from client c join product p on c.pid = p.id where c.id = :id")
        .addEntity("c", Client.class).addJoin("p", "c.product")
        .setParameter("id", id).list();
    return query;
}

Here Jasper JRXML

Client.java:

public class Client  implements java.io.Serializable {

 private Integer id;
 private Product product;
 private String fullname;
 private String business;
 private String address;
 private String city;
 private String mobile;
 private String addedBy;
 private String date;
 private String status;
 private String quotationNo;
 private String valid;
 private String productName;
 private Set orderses = new HashSet(0);

public String getFullname() {
    return this.fullname;
}

public void setFullname(String fullname) {
    this.fullname = fullname;
}  

I've already removed <FieldDescription> from fields in Jasper JRXML

I also tried passing and removing false parameter in new JRBeanColllectionDataSource(collection, false); as follow,

new JRBeanColllectionDataSource(collection);  

Passing "false" parameter only works for JPA criteria for Native query it doesn't matter whether parameter is passed or not it gives

net.sf.jasperreports.engine.JRException: Error retrieving field value from bean: fullname.   

I'm trying NativeQuery to improve speed of JasperReport which is suggested for my previous question

So solution I want either for this one or for my previous question
Jasper Reports 6.14 filling and generating report is so slow [closed]

Your query is select c.*, p.* from ... so Hibernate returns a list of 2-elements arrays: the 1st element is the Client and the 2nd is the Product.

Even though it compiles, the result of the query is not a List<Client>.

You need to convert that list of arrays into a list of Client before sending it to Jasperreports
