Re: Hibernate and iKVM

I worked around the problem with cfg configuration file in java by
modifying my java code to pick a cfg file from a specific location and that
works in java

import java.io.File;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

@SuppressWarnings("deprecation")
public class HibernateDriver {

public void writeUser()
 {
  Configuration configuration=new Configuration();
  File f = new File("C:\\hibernateikvm\\hibernate.cfg.xml");
  configuration.configure(f);
  ServiceRegistry sr= new
ServiceRegistryBuilder().applySettings(configuration.getProperties()).build();

  SessionFactory sf=configuration.buildSessionFactory(sr);

...
}

When I convert my jar file to dll I get these warnings

c:\hibernateikvm>ikvmc -debug -target:library hibernateqboconnect.jar

When I step in writeUser it is giving an exception.

Any suggestions is really appreciated.
