Google マップを使用して Android アプリを開発しています。HTTP REST 経由で JBOSS 7 サーバーを呼び出します。このサーバーは、HTTP REST 経由で別のサーバーを呼び出して、いくつかのオープン データからいくつかのポイントを取得します。次に、最初のサーバーが応答を受け取ると、スマートフォン クライアント用のデータを準備する必要があります。GeoPoint を使用して、OverlayItem の配列リストを作成します。ただし、GeoPoint の作成時には例外があります。

maps.jar と gson-2.2.2.jar を /WebContent/WEB-INF/lib/ に配置しましたが、動作しているように見えますが、Java と JBoss の専門家ではなく、それが正しいかどうかわかりません。

これは JBoss コンソールの例外です。
