Hello, I need to test my DAO classes, but makes this error at
"dao = new UsuariosDAO();":
IllegalStateException: COuld not locate SessionFactory in JNDI.

What can I do? Thanks.


This is the code:

public class UsuariosDAOTest {

private static Usuarios usr = null;
private static UsuariosDAO dao = null;

@BeforeClass public static void runBeforeEachTest() {
usr = new Usuarios();
dao = new UsuariosDAO();
}

@Test public void getUsuarioByNamePass() throws Exception {
usr.setUsuario("USUARIO2");
usr.setPassword("USUARIO1");
usr = dao.getUsuarioByNamePass(usr);
assertNotNull("User found", usr.getUsuario());
}

@AfterClass public static void runAfterEachTest() {
usr = null;
dao = null;
}

public static junit.framework.Test suite() {
return new JUnit4TestAdapter(UsuariosDAOTest.class);
}

}

You test your DAO outside application server? If this is the case, there's no JNDI-context, where you can put your session factory, because without application server there's no naming server. You must create SessionFactory and put it to some other location.

thanks.... and how can i makes a JNDI context? How can i create the SessionFactory?
Can I use HIbernateUtil methods?

public class HibernateUtil {

private static SessionFactory sf;
private static Configuration configuration;

static {
buildSessionFactory();
}

public static void buildSessionFactory() throws HibernateException {
if (sf == null) {
try {
configuration = new Configuration().configure();
sf = configuration.buildSessionFactory();
} catch (HibernateException e) {
}
}
}

public static SessionFactory getSessionFactory() throws HibernateException {
if (sf == null || sf.isClosed()) {
buildSessionFactory();
}
return sf;
}

}

Yes, you can use HibernateUtil methods. In this case you put SessionFactory in static variable of that class.

You can't use JNDI when you don't have its implementation.

Sorry, but I can't do this. I changed this method, and introduced the HibernateUtil.getSessionFactory(), but returns the same exception.
Please, can you tell me what can i do?

Thanks.

@BeforeClass public static void runBeforeEachTest() {
SessionFactory sf = HibernateUtil.getSessionFactory();
usr = new Usuarios();
dao = new UsuariosDAO();
}

Did you remove session_factory_name setting in Hibernate.cfg.xml file for tests? If this property is omitted, the SessionFactory will not be bound to JNDI.

Yes, I have removed it, but i think it isn't necessary because i am running JUnit Test from Eclipse.

The full trace error is:

Can i watch your UsuariosDAO?

Yes, here it is....

public class UsuariosDAO {

private final SessionFactory sessionFactory = getSessionFactory();

protected SessionFactory getSessionFactory() {
try {
return (SessionFactory) new InitialContext().lookup("SessionFactory");
}
catch (Exception e) {
throw new IllegalStateException("Could not locate SessionFactory in JNDI");
}
}


public void persist(Usuarios transientInstance) {
try {
sessionFactory.getCurrentSession().persist(transientInstance);
} catch (RuntimeException re) {
throw re;
}
}

public void attachDirty(Usuarios instance) {
try {
sessionFactory.getCurrentSession().saveOrUpdate(instance);
} catch (RuntimeException re) {
throw re;
}
}

public void attachClean(Usuarios instance) {
try {
sessionFactory.getCurrentSession().lock(instance, LockMode.NONE);
} catch (RuntimeException re) {
throw re;
}
}

public void delete(Usuarios persistentInstance) {
try {
sessionFactory.getCurrentSession().delete(persistentInstance);
} catch (RuntimeException re) {
throw re;
}
}


public Usuarios getUsuarioByNamePass(String usuario, String password) {

try {

Lopd lopd = new Lopd(null);
String pwdencriptada = lopd.encripta(password);
Session session = sessionFactory.getCurrentSession();
Criteria criteria = session.createCriteria(Usuarios.class);
criteria.add(Restrictions.eq("usuario", usuario));
criteria.add(Restrictions.eq("password", pwdencriptada));
Usuarios user = (Usuarios)criteria.uniqueResult();
return user;
} catch (RuntimeException re) {
throw re;
}
}


public Usuarios getUsuarioByNamePass(Usuarios usr) {
String usuario = usr.getUsuario();
String password = usr.getPassword();

return this.getUsuarioByNamePass(usuario, password);

}

public List getUsuarios() {
Session session = sessionFactory.getCurrentSession();
Criteria criteria = session.createCriteria(Usuarios.class);

return criteria.list();
}
}

But in this DAO you, as before, trying to find SessionFactory in JNDI. And when you can't find it, DAO throws IllegalStateException with exactly the same message you've found in console when you run the test. Again, when you run the test, you don't have JNDI-context!

You have two ways, one is to use ServiceLocator wich will find SessionFactory for your environment based on some kind of configuration (maybe properties file), another way is to use some framework with Dependency Injection capabilities.

Yes... sorry but i don't know about this...
could you tell me how can i have JNDI-context?

Thank you

You can't have it without app server! You, certainly, can access JNDI-context if you specify initial context factory class and provider url (with vendor specific values).

For example, for IBM WebSphere Application Server:

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "corbaloc:iiop:myhost.mycompany.com:2809");
Context initialContext = new InitialContext(env);

But in this case you must have running app server, what, from my point of view, make no sense for unit tests. Consider one of the appoaches i point out before.

I am running in JBoss and i proved with this, but it makes the same error in "dao = new UsuariosDAO();" line.... "COuld not locate session in JNDI."

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
Context initialContext = new InitialContext(env);

Did you have application server running when you run the test? Did you provide session_name property in Hibernate.cfg.xml file?

Also, try to put one more environment setting:

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
Context initialContext = new InitialContext(env);

Thank you very much for your help, but i cant do this...

I proved with the server running when I run the test, with and without session_name property in Hibernate.cfg.xml file, but it doesn't run....
