Hello,
I am getting a java.lang.UnsupportedClassVersionError: Bad version number in .class file Exception.
Hibernate version:
I'm using hibernate-3.2 on a Mac OS X 10.5.2 with the following java and javac (pre-installed by Apple):
$ java -version
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)
Java HotSpot(TM) Client VM (build 1.5.0_13-119, mixed mode, sharing)
$ javac -version
javac 1.5.0_13
Code leading to sessionFactory:
I'm trying to run the following simple Hibernate class:
package com.herenow.dataaccess;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
....
public class Setup0
{
public static void main(String[] args) throws IOException {
Setup0 s0 = new Setup0();
s0.populateFIPS();
}
public void populateFIPS() throws IOException {
Configuration cfg = new Configuration();
cfg.configure();
SessionFactory sessionFactory = cfg.buildSessionFactory(); <<<== line 56; Exception here
Session session = sessionFactory.getCurrentSession();
...code to load some data ...
session.getTransaction().commit();
}
Mapping documents:
The relevant part of my hibernate.cfg.xml file is:
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="connection.url">jdbc:postgresql://localhost</property>
<property name="connection.username">hnmdatamanager</property>
<property name="connection.password">intheclear</property>
<property name="connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="current_session_context_class">thread</property>
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="show_sql">true</property>
....<mapping resources.....
</session-factory>
</hibernate-configuration>
Name and version of the database you are using:
I am using PostgreSQL 8.3.1 with the postgresql-8.3-603.jdbc4.jar.
I am running this from ant 1.7 with a target "setup" as follows:
<target name="setup" depends="compile">
<java classname="com.herenow.dataaccess.Setup0">
<classpath>
<path refid="project.class.path"/>
<pathelement location="classes"/>
</classpath>
</java>
</target>

I believe that the jre 1.5.0_13 and javac 1.5.0_13 (pre-installed by Apple) are the only java on the system.
Can anyone help me determine what is going wrong here?
Many thanks in advance,
Ken Bowen
