从Nashron JavaScript运行Java-异常Java.lang.ClassNotFoundException

我已经运行了myjava.jjs，使用Nashorn从JavaScript内部运行Java

var javaClass = Java.type('mypackage.MyJavaClass'); 
javaClass.hello();

运行

package mypackage;

public class MyJavaClass {

    public static void main(String[] args) {
        System.out.println("hello from MyJavaClass.main ");

    }

}

但我明白了

Exception in thread "main" java.lang.RuntimeException: java.lang.ClassNotFoundException: mypackage.MyJavaClass
    at jdk.nashorn.internal.runtime.ScriptRuntime.apply(ScriptRuntime.java:382)

从Eclipse/Enide Studio或在终端jjs runJava.jjs中运行时

所有项目都在

我应该通过类路径运行

jjs -cp ./ runJava.jjs

看

Java应该已经编译好了

javac *.java
