在 WebSphere 8.5.5.2 服务器上调用 RESTful 网络服务时出错
error invoking RESTful webservice on WebSphere 8.5.5.2 server
我已经使用打包在 EAR 中的 Apache Wink 在 WebSphere 8.5.5.2 ND 上部署了 RESTful 应用程序。当应用程序启动时，它会显示“初始化成功”消息：

早些时候，我在 WebSphere 7 上部署了相同的应用程序，并且运行良好。我知道 WebSphere 8.5 附带了 Wink Jars，所以我从 EAR 中删除了这些 jar，然后将其部署到服务器上。此外，我在我的服务器上启用了详细的 class 加载，并发现 class 在服务器启动时正在加载。但是，当我从控制台签入 Class Loader Viewer 时，我找不到 class。将罐子添加到共享库对我也不起作用。如果有人能指出正确的方向来解决这个错误，那将是很大的帮助。
编辑
以下语句在处理程序中出错：
SearchResult result = context.getAttribute(org.apache.wink.server.internal.handlers.SearchResult.class);
WAS 8.5 带有内置的 Apache Wink 1.1。您可以按照以下步骤在 WAS 8.5 上迁移您的应用程序：
1) 从您的应用程序 lib 文件夹中删除所有 apache wink jar。
2) 要构建您的应用程序，您可以使用这两个 websphere jar，com.ibm.ws.prereq.jaxrs.jar 和 com.ibm.ws.prereq.jackson.jar。你可以在 WAS_HOME/plugins 文件夹中找到这些罐子。
3) 使用这些 jar 构建您的应用程序，但不要将这些 jar 打包到您的应用程序 EAR 或 WAR.
4) 如果您的应用程序类型是 EAR，那么确保所有 restful 资源和扩展应用程序 class 的 class 是 war 的一部分。
5) 重新部署您的应用程序，它现在应该可以正常工作了。
