Unable to import sun.org.mozilla.javascript.internal into NetBeans

Question

In my java program, I make heavy use of the Sun implementation for the Rhino script. More recently, however, the JDK does not seem to automatically import the rt.jar file at compile time.

It is strange that NetBeans reports 0 live errors, they appear only when performing a complete cleaning and assembly. This did not happen before when I imported NativeArray, so I'm really confused about why it suddenly stopped working.

Specifications:

• OS - Windows
• Java Version - Java Version 1.6.0_20
• Javac version - javac 1.6.0_20
• NetBeans Version - 6.9

Check if it exists:

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 ();
}

Well, it exists, so here are some test codes:

package testapp;

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

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

. rt.jar JRE . .

Answer 4

This is an old question, however, when I had this problem, my solution was to do more work in the JavaScript environment and then return a primitive type (String / Boolean), not an object.

Of course, this will not satisfy all and all requirements, but in some cases it may help.
