I am wondering any documentation on annotation for people who have used XML mapping file.

For example, I encounter an one-to-many mapping on the String type which I know how to implement with a XML mapping file. I, however, haven't found a reference on annotation for the same subject.

Thanks for you information in advance.

Do you mean: http://www.hibernate.org/hib_docs/annotations/reference/en/html_single?

Thanks for your information. In fact, I already read this document. What I want is a document specially for someone who already use XML mapping mechanism before so that I can quickly figure out anything I need to do with the annotation mechanism. The document can help in the regard, btw.
