Access public enums of Java Classes from JavaScript

[P]

Hi,

Trying to access a public enum in a Java class from JavaScript like Packages.com.mycompany.MyClass.MyEnum, but unfortunatly it fails with the following error:

org.mozilla.javascript.EvaluatorException: Java class "com.mycompany.MyClass" has no public instance field or method named "MyEnum". (internal_anon#1)

Now, I'm using Rhino 1.7R2 and unfortunatly I cannot upgrade. But I wonder if upgrading would help. I tried searching bugzilla to find anything on the topic and also the Google Groups, but no avail.

Only thing I found was this discussion: http://web.archiveorange.com/archive/v/ZPEIkiAkiEnYl4oabuNZ, but it doesn't state if the bug report was ever filed and if something was done with it.

Note: I'm trying to dynamically just access any public enum on any public Java class

I think there is a resolved bugzilla issue for this. It works with current Rhino:

js> java.util.concurrent.TimeUnit.SECONDS.toMillis(123)
123000

Hi Hannes,

Tnx for the response. I've tested your code snippet in Rhino 1.7R2 and there is works as well. So I went and had a look at why it doesn't work for the enum I'm trying to access. This is the simplified version of the code with the enum I'm trying to access from scripting:

package com.mycompany.mypackage;

public class TestEnum

{

public TestEnum()

{

}

public enum testEnum

{

ENUM_TEST_VALUE

}

}

And the JavaScript code I'm using:

var test  = new Packages.com.mycompany.mypackage.TestEnum()

log(test.testEnum.TEST_VALUE)

This setup is a bit different to the setup of the java code you used as example and unfortunately this setup doesn't work in Rhino 1.7R2

Can you confirm it works in the latest Rhino?

It doesn't work with a TestEnum instance, but it works just using the class name, accessing the enum like a static member:

Packages.com.mycompany.mypackage.TestEnum.testEnum.TEST_VALUE

Hi Hannes,

That is one of the many variations I already tried, but that gives me the following error:

org.mozilla.javascript.EvaluatorException: Java class "com.mycompany.mypackage.TestEnum" has no public instance field or method named "testEnum". (internal_anon#1)
