GAE/JavaでWicketを使ってみる - その3

Wicketのセッション情報の書き出し処理中にAccessControlExceptionが発生する件は、以下のようにしてHttpSessionStoreを適用(WebApplicationクラスに記述)する事で回避できた…っぽいｗ

@Override
protected ISessionStore newSessionStore() {
  return new HttpSessionStore(this);
}

「っぽい」って書いたのは、まだ動作していないから。うっかりJPAの処理も含めてしまってデプロイしているせいか、次は以下のようなExceptionに変わった（長いから適当に抜粋した）ｗ

JPAをはずしたら動作してるんかなー。
