Hi Samanthi perera,
You have added your hbm file version but not the annotated class.
When you are using annotated version, it must be specified like or using the package.

Hibernate Annotations comes with a really great documentation for beginners. Read it and you'll see, that you have to write something like that



and not like that



The unfriendly part in "a friendly place for Java greenhorns":
Did you ever hear about such things called "tutorial" or "documentation"? Do you really really really want to learn Java, Hibernate and the other things by posting each and every little problem into forums? You've been told that in some other threads... RTFM! Or try google at first.

Maybe you should repost your configuration, your mapped class and your main class. Because no one knows what you changed between to different runs. E.g. one of your stacktraces contained this: "people/User.hbm.xml". Now you class is Annotation.User or isn't it or is it or not?

There are several classes called Annotation. Maybe Hibernate assumes Annotation.User to be an inner class of some of these classes. E.g. java.text.Annotation. Rename your package to annotation. Naming conventions aren't always useless... In this special case: each part of the fully qualified package-name are written in lower-case.

SessionFactory sessionFack=new AnnotationConfiguration().configure().buildSessionFactory();

I think you are not using the cfg.xml file

That's my guess. I think you are using two classes for building session factory. One is for using cfg.xml file and another one is for annotated version.
If you are using annotated version for building session factory then no need to worry about your cfg file.

this is my user class


this is my cfg.xml


If you are using these two classes can you tell me how to make a SessionFactory using
1)only cfg.xml
2)only annotated class

I think you are not getting my point. post "HibernateUtil" and "AnnotationConfiguration" class codes.

Why are you doing this? If you want to help him, don't ask him for code of AnnotationConfiguration. That's a Hibernate class not his own.

There are two ways to build the session factory. Using cfg.xml file and another one is without using the cfg xml file (in which we can give the configuration details using java code. Which is likely used when we do annotated version).
If we use annotated version then obliviously it has nothing to do with cfg file (since we can configuration details using java code when we build session factory)

Also I don't think that is possible to help without seeing the code

Why should anyone want to get rid of the cfg.xml completly just because he uses annotated entities? You because you CAN configure your annotated classes programmatically it's by far not OBVIOUS that you do not want a hibernate.cfg.xml. You need the class AnnotationConfiguration if you want to use annotated classes, that's the whole difference.
What is easier when you add a new entity? Insert one line in a textfile without recompiling or change code in another class?

BTW we seen his complete code over and over again in the thread and the problem finally got solved...
