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.
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:
at
org.apache.batik.bridge.BaseScriptingEnvironment$1.handleEvent(Unknown
Source) Why is this? Were should I look for further
information about Rhino DOM bindings.
