How to iterate through Java collection in Javascript
<p>I'm trying to do scripting with Javascript in a Java program. I haven't found a way to iterate through a Java collection in Javascript. If I call the iterator() method for the collection, I get the method names instead of the elements.</p>

<p>Here's a sample code:</p>

<pre><code>function getValue(row, components) {
    var apartment = components.get(0);
    var rooms = apartment.getRooms();
    for (var room in rooms.iterator()) {
        println(room);
    }
    return rooms.toString();
}
</code></pre>

<p>The apartment.getRooms() returns a collection of rooms. When I study the value returned by this function, I know that its content are correct, but the values that get printed are the method names.</p>

<p>I invoke the Javascript from my Java program like this:</p>

<pre><code>getInvocable().invokeFunction("getValue", row, components);
</code></pre>
