Jersey を GAE と組み合わせて使用して、RestFul エンドポイントを生成しようとしています。私が従おうとしたガイドはここにあります。ローカルで実行すると、サービスは正しく機能します。GAE にデプロイすると、以下に示すスタック トレースで 500 エラーが表示されます。
Eclipse Juno Service Release 1、AppEngine - 1.7.3、jersey-archive-1.1.5-ea-SNAPSHOT を使用しています
ここに私のWeb.xmlがあります

-->
<threadsafe>true</threadsafe>
<!-- Configure serving/caching of GWT files -->
<static-files>
<include path="**" />
<!-- The following line requires App Engine 1.3.2 SDK -->
<include path="**.nocache.*" expiration="0s" />

<!--
HTTP Sessions are disabled by default. To enable HTTP sessions specify:
<sessions-enabled>true</sessions-enabled>
It's possible to reduce request latency by configuring your application to
asynchronously write HTTP session data to the datastore:
<async-session-persistence enabled="true" />
With this feature enabled, there is a very small chance your app will see
stale session data. For details, see
http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions

</appengine-web-app>
ローカルで動作しますが、GAE にデプロイすると、次の例外がスローされます。

ほぼすべてのことを試しましたが、役に立ちませんでした。これを修正するにはどうすればよいですか?
