[seasar-dev:662] AOPをかけたコンポーネントをシリアライズしたい

[加藤 潤一]

加藤 (j5ik2o) です．

お世話になります．

非常に初歩的な質問なのですが，ちょっと教えてください．

質問は，「AOPをかけたコンポーネントをシリアライズしたい」です．
シリアライズ対象はS2のコンポーネント(POJO)で，Serializableを実装させています．
問題は，readObjectで，java.lang.ClassNotFoundExceptionが発生してしまうことです．(writeObjectでは書き込みはできています)

そもそも，AOPで動的に拡張されたサブクラスを保存しているので，読み込んだ時にそんなクラスないよっていっているのでしょうか？
何かよい解決方法ないでしょうか？

        out.writeObject(task);  // AOPをかけたオブジェクトを書き込み

        task = in.readObject(); // ClassNotFoundException
