Add the hibernate-tools.jar to your java project.
Create this class in your project (i used the default package):
import org.hibernate.cfg.reveng.*;
public class MyRevEngStrategy extends DefaultReverseEngineeringStrategy {
public String getTableIdentifierStrategyName(org.hibernate.cfg.reveng.TableIdentifier t) {return "native"; }
}
in your Hibernate Code Generator, click on browse next to reveng.strategy.
in the textbox type in MyRevEngStrategy, it should find it.
Close and run.
