1. Manual Tecnic
Primerament instalarem el sistema operatiu (windows). Per veure el manual d'instalacio ho podem
veure a les seguents pagina webs segons la versio:
– windows 7: http://www.softzone.es/manuales-software-2/instalar-windows-7-manual-de-
instalacion-de-windows-7/
– Windows xp: http://www.configurarequipos.com/doc317.html
– windows 8: http://www.softzone.es/manual-instalacion-windows-8-instalar-windows-8-
paso-a-paso/
Un cop tenim el sistema operatiu instalat passarem a instalar el xamp, ens descarguem el instalador
desde la pagina web: xamp
Un cop descargat l'executem i seguim els pasos de la instalacio.
Creacio de la base de dades:
anem a: http://localhost/phpmyadmin/
a la pantalla que ens ha aparegut fem clic a l'opcio “base de datos”.
Aqui introduim el nom que li volem dona a la nostra base de datos i li donem a crear:
Un cop creada la seleccionem i creem les taules:
aqui es poden veure les taules que tenim que crear:

2. Taula client:
Taula client_productes: aquesta taula es creada automaticament.
Taula producte:
Taula usuari:

3. Instalacio del IDE de programacio (Netbeans):
El descargarem desde la seguent pagina web:
http://www.oracle.com/technetwork/java/javase/downloads/jdk-7-netbeans-download-432126.html?
ssSourceSiteId=otnes
instalacio: http://www.youtube.com/watch?v=3GhqJyqr_4g
Un cop ja tenim tot aixo pasariem a programar l'aplicacio, iniciem el netbeans.
Crearem un nou projecte, anem a la pestanya “File---New Project...”:
Seleccionem aplicacion java:

4. Fiquem el nom a l'aplicacio i li diem que no volem clase main:
una volta li donem a finish ens apareix el seguent esquema de l'aplicació:
ara tenim que crear nous paquets, boto dret sobre “source packages”:
Creem 5 paquets nous amb els seguents noms:

5. Una volta creat aixo dintre del paquet datos crearem una nova clase java que sera en la que
accedirem a la base de dades:
El seu contingut sera el seguent:
package datos;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

import javax.swing.JOptionPane;

6. //con = DriverManager.getConnection(url, user, password);
String driver = "com.mysql.jdbc.Driver";
String url = "jdbc:mysql://"+host+db;
public void establirconexio (){
try {
Class.forName(driver);
Connection con = DriverManager.getConnection(url,user,password);
} catch (SQLException e) {
System.out.println("SQL Exception: "+ e.toString());
} catch (ClassNotFoundException cE) {
System.out.println("Class Not Found Exception: "+ cE.toString());
}
}
public ResultSet listar (String cadena) throws SQLException{
Connection conexion = null;
try{

ResultSet tbl = obj.executeQuery();
return tbl;
}
catch (Exception e)

return null;
}
finally
{
//conexion.close();
}
}
public int ejecutar(String cadena){
try

int rows = obj.executeUpdate();
return rows;
}

Una volta tenim totes aquestes clases copiades veurem que ens apareix un error a la clase
Producte.java:

15. Si l'obrim i veiem el error podrem veure que es perque ens fa falta una llibreria (hibernate):
Per poder afegir aquesta llibreria primerament ens la tenim que descarga desde la seguent pagina
web: https://skydrive.live.com/#cid=D30581FF3CFC09DF&id=D30581FF3CFC09DF%21136
Descomprimim el fitxer que acabem de descarga.
Una volta descomprimit anem al netbeans i on posa libraries cliquem amb el boto dret i li donem a
add Jar/Folder:
Busquem la carpeta que acabem de descomprimir i obrim tots els jar que hi ham:

16. Com podem veure s'ha solucionat un dels tres errors que teniem. Per poder solucionar els altres dos
falta crear clases que crearem a continuacio.
A continuacio al paquet persistencia crearem la seguent clase i els seguents fitxers xml:
Client.hbm.xml:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

<key column="ID_CLIENT" />
<list-index column="ORDEN" />
<many-to-many class="negoci.Producte" column="ID_PRODUCTE" />
</list>
</class>
</hibernate-mapping>
HibernateUtil.java:
package persistencia;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static
{
try
{
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (HibernateException he)
{
System.err.println("Ocurrió un error en la inicialización de la SessionFactory: " + he);
throw new ExceptionInInitializerError(he);
}
}
public static SessionFactory getSessionFactory()
{

17. return sessionFactory;
}
}
Producte.hbm.xml:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

<property name="usuari" />
<property name="password" />
<property name="tipus" />
</class>
</hibernate-mapping>
Com podem veure a la clase negocio.Producte s'ha solucionat un altre error:

18. Seguidament crearem un nou fitxer xml anomenat “hibernate.cfg.xml” al arrel del programa:
Com es pot veure es crear un nou paquet de forma automatica.
De moment el import de la classe Producte.java que ens esta donan error el comentarem:
Un cop tenim tot aixo passarem a la creacio dels formularis:
Per crear formularis cliquem amb el boto dret del ratoli sobre el paquet persistenica i seleccionem
l'opcio “ New----JFrame form...”:
Introduim el nom del formulari

19. 1- formulari: Formulari de login
Per crear el formulari farem servir el seguent: El formulari quedara de la seguent manera:
Per donar-li nom als controls clicarem amb el boto dret sobre ells i seleccionarem l'opcio
“Properties”:

21. Anirem a la pestanya Code i a la segona opcio ficarem el nom:

22. Un cop tenim el formulari creat passarem a la part de codi:
