GoogleAppEngineでDrEditを実行するのに問題があります。エラーメッセージが表示されます：500サーバーエラー
次のページの指示に従おうとしました： https ：//developers.google.com/drive/examples/java
しかし、私が次の指示に到達したとき：
- プロジェクトのEclipseビルドパスエディターで、およびディレクトリ内のすべてのJARをプロジェクトのビルドパスに追加します。
私は問題があります！
Eclipseではappengine-java-sdk-1.7.3を使用しています
DrEditリポジトリからjarを追加しようとすると、appengine-java-sdk-1.6.3でDrEditが作成されたようですが、2つのバージョンが混在することになります。
そこで、別の方法でDrEditを追加しました。
基本的に、リポジトリからjarの代わりにAPIを追加しました。
より詳細な説明は次のとおりです。
I created an Eclipse App Engine project
then copied the source files from com.google.drive.samples.dredit
to my own com.google.drive.samples.dredit
and I copied the source files from com.google.drive.samples.dredit.model
to my own com.google.drive.samples.dredit.model
また、静的ディレクトリのファイル構造を自分のwarディレクトリにコピーしました。
リポジトリweb.xml、appengine-web.xml、client_secrets.json、logging.propertiesもコピーしました
また、index.jspを使用してテンプレートディレクトリをコピーしました
次に、ドライブAPIとGoogle OAuth2 APIを追加して、ソースファイルに表示されている赤い十字を削除しました。
index.htmlも削除しました
client_secrets.jsonファイルに正しい詳細を入力し、appengine-web.xmlにアプリIDを入力します
ファイル構造は次のようになります
Google App Engineで実行しようとすると、500サーバーエラーが発生します。ログに次のスタックトレースが表示されます
これがスタックトレースです

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
