[Seasar-user:21575] [DOMA]エンティティプロパティへのアクセスに失敗します

[maro]

長岡といいます。
DOMA初心者です。
以下のようなEntityクラスを作りました。

package sae1402.entity;

import org.seasar.doma.Entity;
import org.seasar.doma.Column;

@Entity
public class SAE1402S04SA003Entity {

     @Column(name = "MultiBlockName")
     public String st;

}

実行すると、以下のようなエラーが発生します。
対応方法をご教示頂けませんでしょうか。
