=?iso-8859-2?q?=5BD=B3ugie=5D?= javax.transaction.SystemException z hibernate.
Próbuje użyć hibernate. Na razie udało mi się tyle, że nie
wyskakują żadne błędy podczas kompilowania.
Na razie prosta klasa (id + name) i próbuje.
Po rozwiązaniu kilku problemów wyskakuje mi to(patrz dalej).
Dla pewności przepisałem dokładnie przykład z podręcznika i próbuje
uruchomić.
Wyskakuje coś takiego:

Oprócz dwóch pytań w hibernate.cfg.xml mam jeszcze takie:
3. Skąd wziąć klasę javax.transaction.SystemException? W
dokumentacji ani widu ani słychu.
4. Zagnieżdżony wyjątek oznacza, że nie może się połączyć? Dlaczego?
Pozdrawiam
PS.
Jeśli to pomoże to używam Gentoo
PPS.
Nie działa zarówno na sun-jdk-1.5.0 jak i blackdown-jdk-1.4.2.03

OK.
Hibernate(a zapewnie driver) w przeciwieństwie do mysql(program) nie
traktuje localhost jako socket.
Zostaje javax :)

Problem nr. 2 - tamten szczęśliwie rozwiązany.
Mam taką tabelę:
mysql> desc Category;
+-------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+----------------+
| id | bigint(20) | NO | PRI | NULL | auto_increment |
| name | varchar(255) | YES | UNI | NULL | |
+-------+--------------+------+-----+---------+----------------+
2 rows in set (0.45 sec)
I taką klasę:
package org.dyndns.mojastrona.biblog.core;
public class Category {
public Category() {}
public void setId(Long id) {
this.id = id;
}
public Long getId() {
return id;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
private Long id;
private String name;
}
Klasę zarządzającą:
package org.dyndns.mojastrona.biblog.core;
import org.hibernate.*;
class CategoryManager {
public static void main(String[] args) {
CategoryManager cmg = new CategoryManager();
if(args[0].equals("store"))
cmg.createCategory(args[1]);
HibernateUtil.getSessionFactory().close();
}
public Category createCategory(String name) {
Session session = HibernateUtil.getSessionFactory().getCurrentSessio n();
session.beginTransaction();
Category theCategory = new Category();
theCategory.setName(name);
session.save(name);
session.getTransaction().commit();
return theCategory;
}
}

Jak rozumiem ma problem z dopasowaniem java.lang.String na [VAR]CHAR.
Jak to zrobić?
Co robię źle?
Z manuala wynikałoby, że umie to zrobić.

Cytat
Decede mihi sole - nie zasłaniaj mi słonca.
Gdy kogoś kochasz, jesteś jak stworzyciel świata - na cokolwiek spojrzysz, nabiera to kształtu, wypełnia się barwą, światłem. Powietrze przytula się do ciebie, choćby był mróz, a ty masz w sobie tyle radości, że musisz ją rozdawać wokoło, bo się w tobie nie mieści
Hoc fac - tak czyń.
A tergo - od tyłu; z tyłu.
I czarne włosy posiwieją. Safona |
