In my Spring Controller I have:
List<User> Users = this.userService.UsersList();
mav = new ModelAndView("users");
mav.addObject("Users", Users);
When I iterate over Users I can see all the attributes values of every element of my list.
This is my .jsp code:
<c:forEach items="${Users}" var="usr">
${usr}
</c:forEach>
This is my users class:
#Entity
#Table(name="usuario")
public class User implements Serializable {
#Id
#Column(name="id")
#GeneratedValue(strategy=GenerationType.IDENTITY)

#JoinColumn(name = "id_perfil")

#Override
public String toString() {

}
}
The problem is that ${usr} is only displaying some of my attributes, but not all! I need to display all the attributes in my jsp.
Try using camelCase notation if you are not doing so. For example instead of ${usr.imagen_perfil} use ${usr.imagenPerfil}. I think it will be expecting to use the object getters getImagenPerfil().
I´m using JPA 2.2(Openjpa) running on OpenLiberty and mysqlVer 15.1 Distrib 10.1.21-MariaDB.
I have an object call Account where I use the entityManager.find to retrieve a given record.
The record is indeed retrieved but only this column "status" returns null.
But when I do the manual select against the DB,the value is there.

Has anyone went through this before?
I'm using MySQL and Hibernate. I've added record to Receiving table and have id and barcode fields as foreign keys in transaction table rcid and barcode.
When I search a specific record using id:
int id =(Integer)defaultTableModel.getValueAt(jReceivingsTable.getSelectedRow(),0);
Receivings receivings = manager.searchReceivingsId(id);
that doesn't null, printing id return appropriate value so why I'm getting null when I set it to Transaction table?
Rctransaction rctransaction = new Rctransaction();
rctransaction.getReceivings().getId().setId(id); // here id has value
rctransaction.getReceivings().getId().setBarcode(barcode);
rctransaction.setReceivings(receivings);

You are instantiating the Hibernate objects in the wrong order.
First you need a ReceivingsId :
ReceivingsId rid = new ReceivingsId (id, barcode);
Then add this rid to a Receivings:
Receivings rec = new Receivings();
rec.setId(rid);
And finally set it to the Rctransaction:
Rctransaction rctransaction = new Rctransaction();
rctransaction.setReceivings(rec);
If you try to call getReceivings after instantiating the object without setting it before you'll always get a NullPointerException. To avoid this, you can instantiate the Receivings object in the Rctransaction constructor.
I started to study java and i'm try to do a simple system to associate students and subjects, my problem is how can i associate one student to many subjects, i hope you can help me.
Main Class
package exercicios;
public class Exercicio3_Main {
public static void main(String[] args) {
//Criando Alunos
Exercicio3_Aluno aluno[] = new Exercicio3_Aluno[3];
aluno[0] = new Exercicio3_Aluno("Douglas", "Telematica", 201391);
//Criando as Disciplinas
Exercicio3_Disciplina disciplina[] = new Exercicio3_Disciplina[7];
disciplina[0] = new Exercicio3_Disciplina("POO");
aluno[0].cadastrarDisciplina(disciplina[0]);
//aluno[0].listarAluno();
}
}
Student Class
package exercicios;

The output of this code is something like this:
Nome: Douglas
Curso: TLM
Matrícula: 102050
Disciplinas: Programação Orientada a Objetos
What i need is list many subjects to students, i know it's probably is very simple but i started to study this now and all of this is new for me ;D
Instead of one subject, you want multiple subjects on the student so use List<Subjects> on the student class and adjust the getters and setters as such. You can then add subjects to the list on the student.
Sample code
public static void main(String[] args) {
//Criando os Alunos
Exercicio3_Aluno aluno[] = new Exercicio3_Aluno[3];
aluno[0] = new Exercicio3_Aluno("Douglas", "TLM", 102050);
//Criando as Disciplinas
Exercicio3_Disciplina disciplina[] = new Exercicio3_Disciplina[7];
disciplina[0] = new Exercicio3_Disciplina("Programação Orientada a Objetos");
disciplina[1] = new Exercicio3_Disciplina("Sistemas Operacionais");
//Mostrando os dados do Aluno
aluno[0].cadastrarDisciplina(disciplina[0]);
aluno[0].cadastrarDisciplina(disciplina[1]);
aluno[0].listaAluno();
}
In your student method
//Lista o Aluno
public void listaAluno(){
System.out.println("--------- DADOS DO ALUNO --------");
System.out.println("Nome: " + this.nome);
System.out.println("Curso: " + this.curso);
System.out.println("Matrícula: " + this.matricula);
System.out.println("Disciplinas: ");
String disciplinasString = "";
for(Exercicio3_Disciplina disciplina : this.disciplinas)
{
disciplinasString = disciplinasString + disciplina.getNome());
}
System.out.println(disciplinasString);
System.out.println("---------------------------------");
}
I'm trying to make a program that asks for an ID. it stores the ID and if you want to search it, you type the ID and click "Search". The program will show information of the ID. (Name, Adress, Phone number, etc). The problem is that when i click "Search" it gives me this error(shown at title). I may have forgotten some information, if so please tell me. Im new to this website and Java and i couldn't find anything on google that would FIX it.

The problem was that i was using the wrong object. I was using lb_ID instead of jt_ID at String idStr = lb_ID.getText();.
