Vaadin JPAContainer2.0でHibernateを設定する

Question

JPAContainerがeclipselinkではなくhibernateを使用するように、Vaadinデモを変換しようとしています。しかし、私はそれを働かせるように見えることはできません。ここで

アイブ氏は、MySQLコネクタと一緒にHibernateのライブラリが含まれて/ WEB-INF/libに/

で

私はこれをほぼ一日中しみっていて、どこでそれを使っていないのですか？どんなヘルパーも高く評価されます。

Iveは以前のバージョンのhibernate 3.xを使用してこれを動作させました。もともと私はhibernate 4.xを使用していましたが、私が試みていた方法で使用することを許さなかったそのバージョンの設定変更があったに違いないと思います。
