GAE で Spring Frameworkを動かしてみる
手ごろなサンプルがなかったので、Spring Framework MVCの Spring-MVC-step-by-step の中で作成するアプリでも動かしてみることに。
- Basic Application and Environment Setup
- Developing and Configuring the Views and the Controller
- Developing the Business Logic
までは上手く動いたんだけど、その次の 4. Developing the Web Interface でエラーが発生。ローカルで試したときには上手くいったんだけど、サーバ上で動作させると以下のエラーが。

セッションで共有しているFormをシリアライズしようとしてる？試しにsessionFormをfalseに変えてみた。

なんでjava.security.AccessControlExceptionをjavax.servlet.ServletExceptionにキャストしようとしてる？うーん、これ以上は大変そうだ・・・。
とりあえずSpring Frameworkが利用できることと、セッション周りを気をつけた方が良いことは分かったかも。セッション周りは素のServlet APIを利用してどこまで出来るか試してみるか。
