I looked into how to configure the persistence.xml file in a basic way, but I was even more confused about this configuration.

So, I'd like to know how I can do a basic configuration in the persistence.xml file according to JPA and Hibernate to access a database no SQL Server 2008 ?

Information regarding the database:

My Connection String:

"Data Source=CARVALHO-PC\LOGIXMINESYSTEM;Initial Catalog=TarefaExemplo;Persist Security Info=True;User ID=sa;Password=minhasenha"

The bank has a single table named tarefas with the fields id int , descricao VARCHAR(50) , finalizado int and data_finalizado DATETIME .

Information regarding the structure of the project and the application:

I have already added all JARs for Hibernate and JPA and also the JDBC driver for SQL Server.

And the project structure looks like this:

...\EXEMPLOHIBERNATE\SRC
├───exemplohibernate
├───META-INF
└───model

Since within the model package there is a single class, class Tarefa :

package model;

import java.util.Calendar;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
/**
 * @author Dener
 */

@Entity
@Table(name="tarefas")
public class Tarefa {

    @GeneratedValue    
    @Id
    private Long id;

    private String descricao;
    private boolean finalizado;

    @Column(name = "data_finalizado", nullable = false)
    @Temporal(TemporalType.DATE)
    private Calendar dataFinalizacao;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getDescricao() {
        return descricao;
    }

    public void setDescricao(String descricao) {
        this.descricao = descricao;
    }

    public boolean isFinalizado() {
        return finalizado;
    }

    public void setFinalizado(boolean finalizado) {
        this.finalizado = finalizado;
    }

    public Calendar getDataFinalizacao() {
        return dataFinalizacao;
    }

    public void setDataFinalizacao(Calendar dataFinalizacao) {
        this.dataFinalizacao = dataFinalizacao;
    }

}

This is the class that has annotations for the Framework. And the other packages do not contain classes yet.

Note:

  

The example application is for the desktop platform and the IDE I'm using and NetBeans.
