I would recommend you read this tutorial and it should get you started.

http://www.hibernate.org/hib_docs/v3/re ... orial.html

It does sound like you've copied all of your files into your JDK directory which would be a bad idea.

You should have some kind of development directory and then a project directory under that.



put your .java files in your src directory and the .class files into bin.
