The Magic of Using Hibernate

The new project(actually just new for me, this project has been there for 1.5 years) has many duplicated codes. And the client, may ask for adding or reducing functions or fields or other database schema change requirement, which could a a nightmare if it applies to the my project in 2002.

With Hibernate, it will map the database table to the object. Because I didn't operate the database directly, the application is loss coupling with the database. Adding and reducing table field never becomes so easy and safe. It is just amazing!

Symptom: 1.        The JVM became Out of memory when creating big consumption report 2.        Those JRTemplateElement-instances is still there occupied even if I logged out the system Reason:         1.
