I sure got off the wrong foot with Hibernate. I'm blocked by this error when I'm trying to intitialize hibernate. Here's what I'm trying to do:
Code:
...
private static final ThreadLocal threadLocal = new ThreadLocal();
...
public static Session currentSession() throws HibernateException {
Session session = (Session) threadLocal.get();
if (session == null) {
if (sessionFactory == null) {
try {
cfg.configure(CONFIG_FILE_LOCATION);
sessionFactory = cfg.buildSessionFactory();
}
catch (Exception e) {
Logger.getLogger("problem").error("Error initializing Hibernate!",e);
}
}
session = sessionFactory.openSession();
threadLocal.set(session);
}
return session;
}
The problem happens where I have the try/ctach. Here it is:
Code:

So apparently I attempt to import "accounts" twice... Here's my hibernate.cfg.xml:
Code:
<hibernate-configuration>
<session-factory>
<!-- properties -->
<property name="connection.username">xxx</property>
<property name="connection.url">jdbc:mysql://xxx:3306/</property>
<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>
<property name="connection.password">xxx</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<!-- mapping files -->
<mapping resource="org/ablogic/hibernate/Accounts.hbm.xml"/>
<mapping resource="org/ablogic/hibernate/AccountAttributes.hbm.xml"/>
<mapping resource="org/ablogic/hibernate/AccountPrivileges.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Any idea what could be causing this error?
