Hallo,

ich möchte eine WebApp mit/für folgenden Mitteln entwickeln:
Webserver: Apache Tomcat 5.5.17
Java: Java SE 5.0
Logger: Log4J
DB: Mysql 5.0.22

und natürlich Hibernate (aktuelle Version) ;-)

Mein Problem befasst sich mit den Hibernate-Mapping XML-Dateien. Bevor ich hier lange mit eine Beschreibung ausholle, poste ich einfach einmal ein paar Codes stücke.

hibernate.cfg.xml
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

    <session-factory>
        <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property>
        <property name="hibernate.connection.password">schule11</property>
        <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/universe</property>
        <property name="hibernate.connection.username">HibernateWeb</property>
        <property name="hibernate.c3p0.min_size">5</property>
        <property name="hibernate.c3p0.max_size">30</property>
        <property name="hibernate.c3p0.timeout">2000</property>
        <property name="hibernate.c3p0.max_statements">100</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <mapping resource="Abc.hbm.xml" ></mapping>
    </session-factory>
</hibernate-configuration>


Abc.hbm.xml
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

MySQL:
database: universe

table: abc
-> Id integer not null primary key auto_increment
-> a integer not null

Warum bekomme ich diese Fehlermeldung? Ich muss zugeben, dass ich gerade erst mit Hibernate befasse und somit noch keine Erfahrung damit besitzte. Doch ich komme hier einfach nicht weiter :-( Kann mir hier jemand helfen?

MfG,
Thomas

Die Ressource muss wohl beans/ABC heißen. Außerdem würde ich dringend davon abraten, so die ersten Hibernate Klassen zu erstellen.

Du wirst Dich runzelig deployen und neustarten. Erstelle eine Simple Java application zum testen der Hibernate funktion. Wenn Dein Hibernate Layer läuft, kannst Du weiter machen.

Hallo LaLiLuna,

das hier ist eine Simple Java application :-) nur das ich einen Logger hinzugefügt habeb und die Scripts mit Tomcat startet. Naja egal

Wenn du mit Ressource die Bean-Klasse (package beans) Abc.class meinst, ja.
