我是关于在 stackoverflow 上发布答案的新手。我希望你能帮助我。
我正在使用谷歌地图开发一个安卓应用程序。它通过 HTTP REST 调用 JBOSS 7 服务器，该服务器通过 HTTP REST 调用另一个服务器以从一些开放数据中获取一些点。然后，当第一个服务器收到响应时，它必须为智能手机客户端准备数据。因此，它使用 GeoPoint 准备了一个 OverlayItem 的数组列表。但是在创建 GeoPoint 的时候有一个例外。
我已将 maps.jar 和 gson-2.2.2.jar 放在 /WebContent/WEB-INF/lib/ 中，它似乎可以工作，但我对 Java 和 JBoss 不是那么专家，不知道它是否正确。
这是 JBoss 控制台中的异常：
