我正在尝试读取 Windows 事件日志，因此我使用 Jinterop API。
这是java代码:

catch ( Exception e )

我正在使用 Ubuntu 并尝试从远程计算机读取日志。当我运行下面的代码时，我收到“RPC Stub”异常。

我在 google 上搜索了该异常，发现 jar 丢失，因此我添加了相应的 Jar 文件，但仍然遇到相同的问题。
有人可以告诉我如何解决这个问题吗？ 谢谢。
最佳答案
我解决了这个问题。我添加了包含 rpc.Stub 类的 jaxpc-api.jar 文件，但还有更多包含 rpc.Stub 类的 API，因此不包含 jaxpc-api.jar 文件。
有 j-interopdeps.jar 文件，其中包含为此目的的 rpc.Stub 文件，还需要 1 个 jar 文件，即 jcifs-1.3.14.jar 文件。将这 2 个 jar 文件包含在构建路径中后。如果用户名、密码和主机名正确，程序将执行。
关于java - 线程 "main"java.lang.NoClassDefFoundError : rpc/Stub 中出现异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33144304/
