I have been using the ASV3 viewer and am currently revising the
ecmascript code to get it to work in Batik/Rhino. I realise that Adobe
have implemented a number of non-standard features. However one feature
that I use extensively is the addEventListener(eventType, listener,
useCapture) method of registering event listeners on a particular node.
Your sample file works fine for me (when I click on the menu Items
I get alerts).
You should be using at least Batik 1.5, or you may want to pick up
current CVS (we make nightly source dumps available as well).
The argument I typically pass to the listener parameter is 'this'. Then
I implement a handleEvent method for the prototype. I have used this
method to define generic event handlers on objects quite successfully. I
have included a file demonstrating this. Note that although this works
fine in ASV3, I am getting the following error in Batik.

I think the key line here is:

Why is this? Were should I look for further information about Rhino DOM
bindings.
