Hi zusammen,

da ich mich in Hibernate einarbeiten will, so dachte ich mir probier einfach mal folgendes Beispiel aus:

www.laliluna.de/first-hibernate-example-tutorial.html

Da ich hierbei HSQL verwenden will, habe ich mir vorher die entsprechende Datenbank mit der Tabelle erzeugt.
Nach der Befolgung des Tutorials erhalte ich beim Start der Testapplikation folgende Fehlermeldung (auf das Wesentliche gekürzt):

Meine Konfigurationsdatei(hibernate.cfg.xml) befindet sich im Root-Verzeichnis und beinhaltet folgenden Code:

Da ich noch neu auf dem Gebiet bin, wäre ich euch sehr dankbar, wenn ihr mir bei der Fehlersuche behilflich sein könntet.

> select next value for honey_id_seq from dual_honey_id_seq
vielleicht
select next value as honey_id_seq from dual_honey_id_seq

-----

weißt du generell etwas von der honey_id oder auch dual_honey_id,
hat die jemand angelegt?

Ich habe folgendes HSQLDB-Statement zur Generierung der Datenbank verwendet:

Code: 
CREATE TABLE honey(id INTEGER IDENTITY, name VARCHAR, taste VARCHAR)

In dem Tutorial werden lediglich die Statements für MySQL oder PostgreSQL verwendet. Beispiele für die Statements aus dem Tutorial:
PostgreSQL:
Code: 
CREATE TABLE "public"."honey" (  id SERIAL,   name text,   taste text,   PRIMARY KEY(id));
MySQL:
Code: 
CREATE TABLE `honey` (  `id` int(11) NOT NULL auto_increment,  `name` varchar(250) default NULL,  `taste` varchar(250) default NULL,  PRIMARY KEY  (`id`)) ENGINE=MyISAM CHARSET=latin1

Meiner Ansicht nach sollte das HSQL-Statement richtig sein.

Lass dir das ganze generieren. Es gibt dazu Ant-Tags (Stichwort: HibernateTool; hbm2ddl).

Damit sollte alles funktionieren. Ich könnte aber schwören, dass ich mich auch schon vorher exakt an die Angaben gehalten habe.

Hallo,

        tx.rollback();
    }
  }
}
Liegt vielleicht ein Fehler in der config-Datei?
