- Setting the CLASSPATH to 10 consecutive values doesn't work. It only takes the last value. You need to set it =%classpath%;. You also need to quote all those directories with spaces in their names.
- Putting policy.all on the CLASSPATH is pointless.
java.lang.ClassNotFoundException: ExecutorInterfacesays exactly what is wrong. That class is not present at the client.
- 将 CLASSPATH 设置为 10 个连续值不起作用。它只取最后一个值。您需要将其设置为 =%classpath%;。您还需要引用所有名称中带有空格的目录。
- 将 policy.all 放在 CLASSPATH 上是没有意义的。
java.lang.ClassNotFoundException: ExecutorInterface准确地说出了什么问题。该类不存在于客户端。

Simple solution is that Add ExecutorInterface.class or its related jar in your client project class path.
简单的解决方案是在您的客户端项目类路径中添加 ExecutorInterface.class 或其相关的 jar。
