Question

I have a HibernateUtil class that initialize a SessionFactory during its initialization. Below is the snapshot of the code that do the initialization.

public class HibernateUtil {

  ...

  static {
    try {
      if (cacheFactory.get("factory") == null) {
        sessionFactory = new Configuration().configure().buildSessionFactory();
        cacheFactory.put("factory", sessionFactory);
      }
      else {
        sessionFactory = (SessionFactory) cacheFactory.get("factory");
      }

    } 
    catch (HibernateException ex) {
       throw new RuntimeException(ex.getMessage(), ex);
    }
  }
}

I tested this code run under JDK6 and WAS8 environment then it is working fine. But when I moved to Tomcat7 with JDK6 then it will failed at buildSessionFactory(). The Hibernate version that I’m using is 3.6.10.Final. I’m just curious whether Hibernate 3 doesn’t support in Tomcat 7?

Answer 1

Hibernate is supported like any other Java-based framework. Check the log for other errors.

Also the code in question is related to Hibernate but org.huahsin is probably not something from the Hibernate project.
