我在一台机器上得到了`noclassdeffounderror`

我已经将NetTy项目打包为JAR，并且在本地和一台服务器上正常工作，但是它会抛出java.lang.noclassdeffounderror在另一台服务器上例外。此外，如果我使用JRE而不是JAVA带有JDK（同一版本）的JRE 启动JAR，则可以再次起作用。

如果此罐子在某个地方工作，则意味着罐子已经包装了所需的类，那么可能会导致问题呢？

I have packaged my netty project as a jar, and it works fine locally and on one server, but it will throw java.lang.NoClassDefFoundError exception on another one. Furthermore, if I start the jar with java from jre instead of java comes with jdk (same version), it works again.

If this jar works somewhere, it means the jar has already had the required classes packaged, then what might cause the problem?
