Getting an hibernate3 SessionFactory

Hibernate ORM
1

I keep getting this message

java.lang.NoSuchMethodError: 'org.hibernate.classic.Session org.hibernate.SessionFactory.getCurrentSession()'

From what I have read this happens if i have Hibernate 3 jars on the classpath. I can’t figure out where it would come from. I have searched all jars named hibernate looked into them and I can’t find the classic Session class anywhere. Can this be the problem in my case?

I am starting to believe that I have configuration that creates this session factory (maybe classpath entry). What selects the instance of sessionfactory when it is created from configuration?

Any tips on what I can do?

You should see what the calling method is in the stack trace.

I don’t really get good stacktrace.

It fails on this line:
SessionFactoryHelper.getInstance().getCurrentSession();

Where getInstance() somehow gets an hibernate3 session factory.

I create the session factory with this code:

Configuration cfg = getConfiguration();
sessionFactory = cfg.buildSessionFactory();

This is the code in getConfiguration()

           Map<String, String> propMap = SystemConfiguration.getPropertyMap("hibernate.", false);

            Properties props = new Properties();
            props.putAll(propMap);

            if (LOG.isLoggable(Level.FINER))
            {
                String msg = "hibernate properties: " + props;
                LOG.logp(Level.FINER, CLASS_NAME, methodName, msg);
            }

            /* Init a hibernate configuration with the props Property */
            cfg = new Configuration();
            cfg.setProperties(props).addResource("idainfront/digg/adapter/interceptors/LogData.hbm.xml");

And finally this is the values returned by SystemConfiguration.getPropertyMap()

If your code swallows the exception and just prints the exception message, maybe you should try removing this logging or set a break point on that line to acquire the stack trace.

You got my hopes up. A swallowed exception that could have explained things. But no. There is no swallowed exceptions.

I have now run the code in the debugger. There the assignment work when I run a similar snippet there. I don’t even try to call the same method. There I have org.hibernat.Session getCurrentSession().

I you have given me an idea what is the problem while looking for this swallowed execption. It fails when I start a transansaction with an txutil class that my company has done. It could be something there that is calling the wrong methods.

I have found the problem. It had nothing to do with hibernate it self. I had a build problem issue.

I had a bad SNAPSHOT version in my local cache. Where I had compiled a jar against an old hibernate version.

This kind of problem can be seen with javap -cp <jar> -c className

private org.hibernate.Session getSession();
    Code:
       0: aload_0
       1: getfield      #5                  // Field mSession:Lorg/hibernate/Session;
       4: astore_1
       5: aload_1
       6: ifnonnull     18
       9: invokestatic  #6                  // Method idainfront/digg/adapter/interceptors/SessionFactoryHelper.getInstance:()Lorg/hibernate/SessionFactory;
      12: invokeinterface #7,  1            // InterfaceMethod org/hibernate/SessionFactory.getCurrentSession:()Lorg/hibernate/classic/Session;
      17: astore_1
      18: aload_1
      19: areturn
