URL（ログイン画面）にアクセスし、jsessionid（J2EEJSESSIONID）を取得してCookieストアに追加し、コンテキストに追加して、資格情報で同じURLにアクセスしようとしています。ログイン成功画面が表示されることを期待しています。ただし、ログイン画面で再びバウンスされます。そして、両方のヒットの応答ヘッダーを出力しました。セッションを維持するために、同じ J2EESESSIONID を持つ両方の応答を期待しています。代わりに、両方のセッション ID が異なります。助けてください。

別の観察: 以下のスニペットから "A" 連結を削除すると、2 番目のヒットで J2EESESSIONID が取得されません。
BasicClientCookie cookie = new BasicClientCookie(strArray[0], "A"+cookieValueArray[0]);
