Pessoal será que alguém poderia me ajudar?
estou tentando executar a seguinte query:
public List<CandidateSummary> searchCandidateByPosition(Position position, Opportunity opportunity){
if(position == null || position.getId() == null){
return new ArrayList<CandidateSummary>();
}
StringBuffer ejbql = new StringBuffer("select new CandidateSummary(");
ejbql.append("o , ");
ejbql.append("(select count(c) from Contact c where c.candidate = o and c.opportunity = :opContact), ");
ejbql.append("(select count(d) from OpportunityDelivery d where d.candidate = o and d.opportunity = :opDelivery)");
ejbql.append(") from ");
ejbql.append("Candidate o where o.id is not null and ");
ejbql.append("(exists (select cpp.position from o.candidatePositionList cpp where cpp.position = :position)) order by o.firstName");
Query query = em.createQuery(ejbql.toString());
query.setParameter("opContact", opportunity);
query.setParameter("opDelivery", opportunity);
query.setParameter("position", position);
return query.getResultList();
}ou seja quero popular um outro objeto chamado CandidateSummary segue a classe na integra:
package br.com.walar.recruitment.model.candidate.helper;
import br.com.walar.recruitment.model.candidate.entities.Candidate;
public class CandidateSummary {
private Candidate candidate = new Candidate();
private Boolean contacted = false;
private Boolean delivered = false;
public CandidateSummary(Candidate candidate, Integer contact, Integer delivery) {
this.candidate = candidate;
this.contacted = (contact != 0);
this.delivered = (delivery != 0);
}
public void setCandidate(Candidate candidate) {
this.candidate = candidate;
}
public Candidate getCandidate() {
return candidate;
}
public void setContacted(Boolean contacted) {
this.contacted = contacted;
}
public Boolean isContacted() {
return contacted;
}
public void setDelivered(Boolean delivered) {
this.delivered = delivered;
}
public Boolean isDelivered() {
return delivered;
}
}
com as informações
do candidato , quantos contatos foram feitos referente a uma oportunidade que passo como parametro
e quantoso e-mail ja foram enviados para ele referente a mesma oportunidade;
porém só me da este erro:
