【问题描述】：
我是 openshift 的新手，我使用 netbeans 和 tomcat 7 开发了一个 restful 服务项目并将其部署在 openshift 上，以便在一个小型 android 项目中使用它来学习一些 android 的东西。 当我使用邮递员从本地主机调用服务时，它返回结果，但是当我从 openshift 调用它时，它返回此错误 HTTP Status 500 - Servlet.init() for servlet Jersey REST Service throw exception 考虑到当我调用项目链接而不扩展 servlet 和服务“servlet 映射”时，它返回相同的 index.html。
这将返回 http 状态 500

虽然这行得通 http://localhost:8080/AndroidBackEndTest2/services/getStudents
这是项目的 web.xml 文件 `

这是openshift的响应表单
