Google App Engine（Java）とPayPalプロセスを初めて使用しています。GAE/J、PayPalリクエスト - NoClassDefFoundError（AuthorizationRequiredExceptionの場合）
キャッチされない例外サーブレットから ます。java.lang.NoClassDefFoundError：COM /ペイパル/適応/例外/ AuthorizationRequiredException
ここでは私のサーブレットである私は、チュートリアルでは、なぜ私は次の例外を取得していてくださいhttp://googleappengine.blogspot.com/2010/06/paypal-introduces-paypal-x-platform.htmlを提供し、NOTを使用しています事前承認を行うと事前承認キーと認可のURLを提供すると仮定し、クラスファイル..あなたはlibディレクトリにpaypal.jarを持っている場合
