无法在NetBeans中导入sun.org.mozilla.javascript.internal [英] Can't import sun.org.mozilla.javascript.internal in NetBeans

问题描述

在我的Java程序中，我大量使用了Rhino脚本引擎的Suns实现.但是最近，我的JDK似乎在编译时不再自动导入rt.jar文件.

In my java program I make heavy use of Suns implmentation of the Rhino script engine. Very recently however, my JDK does not seem to automatically import the rt.jar file anymore when compiling.

奇怪的是NetBeans报告了0个实时错误，它们仅在执行完整的Clean& amp;时才会显示.建造.在导入NativeArray之前，这还没有发生过，所以我对为什么突然停止工作感到困惑.

Whats strange is that NetBeans reports 0 live errors, they only show up when doing a complete Clean & Build. This wasn't happening before when I was importing NativeArray, so I'm really confused on why it all of a sudden stopped working.

规格:

• 操作系统-Windows
• Java版本-Java版本"1.6.0_20"
• Javac版本-javac 1.6.0_20
• NetBeans版本-6.9

检查是否存在:

C:\Documents and Settings\LordQuackstar\Desktop\TestApp\src>javap sun.org.mozill
a.javascript.internal.WrappedException
Compiled from "WrappedException.java"
public class sun.org.mozilla.javascript.internal.WrappedException extends sun.or
g.mozilla.javascript.internal.EvaluatorException{
    static final long serialVersionUID;
    public sun.org.mozilla.javascript.internal.WrappedException(java.lang.Throwa
ble);
    public java.lang.Throwable getWrappedException();
    public java.lang.Object unwrap();
}

好了，所以这是一些测试代码:

Ok it exists, so here's some test code:

package testapp;

import sun.org.mozilla.javascript.internal.WrappedException;

public class Main {
    public static void main(String[] args) {
        WrappedException e = new WrappedException(null);
    }
}

Netbeans输出:

那么什么会导致它突然失败呢?昨天工作还不错.除了从同一包中导入2个以上的类之外，我没有进行任何更改.我的依赖项都没有改变.

So what would cause this to fail all of a sudden? It was working just fine yesterday. I didn't change anything besides importing 2 more classes from the same package. None of my dependencies changed.

将在linux中进行测试，以查看问题是否仍然存在.

Will test in linux to see if the problem still exists.

在您说出来之前:不，我不会分开下载犀牛，不，我不会更改IDE，

Before you say it: No I'm not download rhino separatly, No I'm not changing IDEs,

推荐答案

有两个迹象表明您不应使用此类:sun和internal-这意味着这是一些不应使用的内部类供第三方使用.因为它可以更改或在将来的版本中删除-即，这不是API的一部分.所以-单独下载Rhino.

There are two indications that you shouldn't use this class: sun and internal - these mean that this is some internal class that shouldn't be used by third parties. Because it can change or be removed in future releases - i.e. this is not part of an API. So - download Rhino separately.

如果您使用脚本API，请仅使用API​​类/接口-即

If you are using the scripting API - use only the API classes/interfaces - i.e. javax.script
