我有一个为管理我们的应用内计费而开发的网络服务。现在我想对其进行更改以包括对 Android Subscription API 的支持。所以我必须使用 OAuth 来查询 Google 的服务器。
我的代码完美地作为基于控制台的应用程序工作。但是，当我尝试将其发布为 Web 服务时，我得到以下异常。是某种错误还是我做错了什么？如果我错了，请指导我。

以下是我用过的 jar 。
最佳答案
java.lang.NoClassDefFoundError: com/google/api/client/http/HttpRequestInitializer
这表示。
This runtime error is thrown by the JVM when there is an attempt by a
ClassLoader to load the definition of a Class (Class referenced in your
application code etc.) and when such Class definition could not be found
within the current ClassLoader tree.
可能是类路径设置不正确。
