I would really appreciate some assistance with this problem. I have used Hibernate 1.2 in the past and this worked very well. I am trying out Hibernate 2 for the first time and having some problems.

I saw a very brief answer to this in the FAQ that mentioned something about Classic VM but didn't go into any detail.

Version: Hibernate 2.1 beta 3b, and 2.0.3
Java: Blackdown 1.3.1 02c FCS
Linux: Yellowdog 3.0 (PPC)
Database: Postgresql 7.2.3

When using Hibernate 1.2 beta3b I get the following error:

1) testLoadPage(ca.realtypages.engine.test.PersistenceTest)java.lang.AbstractMethodError: net/sf/hibernate/persister/AbstractEntityPersister.getTableName
at net.sf.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:148)

With hibernate 2.0.3 I get this error:

1) testLoadPage(ca.realtypages.engine.test.PersistenceTest)java.lang.AbstractMethodError: net/sf/hibernate/persister/AbstractEntityPersister.lock

Both errors seem to be occuring when I initialize Hiberante with the buildSessionFactory call. Here is my initialization code:

Iterator persistentclasses = props.getVector("hibernate.persist").iterator();
net.sf.hibernate.cfg.Configuration hibconfig = new net.sf.hibernate.cfg.Configuration();
try {
while (persistentclasses.hasNext()) {
String classname = (String)persistentclasses.next();
Class c = Class.forName(classname);
hibconfig.addClass(c);
}
sessions = hibconfig.buildSessionFactory();
} catch (Exception e) {
log.error("Error",e);
throw new DatasourceException(e.getMessage());
}

Thanks in advance!

Did you build hibernate, or use the pre-built jar from the dist?

I used the pre-built jar from the dist.

Thanks for the quick reply to my post!

I rebuild the Hibernate 2.0.3 jar and that solved my problem.

Thanks!
