[Seasar-user:3333] instance属性でrequestを設定するとnullでエラーになる

[[E-MAIL ADDRESS DELETED]]

お世話になります。おおにしです。

instance属性にrequestを設定して実行すると
「[ESSR0007]requestはnullあるいは空であってはいけません」
とエラーがでます。

diconファイルのDOCTYPE宣言は全て23のものいしています。
S2ContainerFilterは設定しているので問題ないはずなのですが原因がわかりません。

環境：
IDE:WebSphere 5.1.2
S2:2.3.4

よろしくお願いします。
