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Google Map 开发Android应用 . 它通过HTTP REST调用JBOSS 7服务器，该服务器通过HTTP REST调用另一台服务器从某些Open Data获取一些点 . 然后，当第一台服务器获得响应时，它必须为智能手机客户端准备数据 . 因此，它使用GeoPoint准备OverlayItem的数组列表 . 但是在创建GeoPoint时有一个例外 .
我在/ WebContent / WEB-INF / lib /中放了maps.jar和gson-2.2.2.jar，看起来它有效，但我对Java和JBoss并不那么专业，也不知道它是否正确 .
这是JBoss控制台中的例外：
