JavaScript issues?

Hi all,
 
I'm trying to incorporate JavaScript into one of my SVG files and I'm running into trouble.  I'm sure it's something I've done because it's a custom canvas class and I'm directly using Rhino:
 
The SVG:
 
<svg contentScriptType="text/ecmascript" ...>
    <script type="text/ecmascript">
        <![CDATA[ ... ]]>
    </script>
</svg>
 
The canvas:
 
public class CustomCanvas extends JSVGCanvas {
    public CustomCanvas() {
        super();
        this.setDoubleBuffered(true);
        this.setDoubleBufferedRendering(true);
        this.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
    }
}
 
I'm building with Maven so my project has a dependency on Rhino 1.7R1 for the js.jar.
 
When I load the SVG with the canvas, I get a pop-up error:
SVG Error:  Unknown language: text/ecmascript
 
Details:
 
java.lang.Exception: Unknown language: text/ecmascript
 at org.apache.batik.bridge.BridgeContext.getInterpreter(BridgeContext.java:575)
 at org.apache.batik.bridge.BaseScriptingEnvironment.getInterpreter(BaseScriptingEnvironment.java:289)
 at org.apache.batik.bridge.BaseScriptingEnvironment.loadScripts(BaseScriptingEnvironment.java:404)
 at org.apache.batik.bridge.UpdateManager.dispatchSVGLoadEvent(UpdateManager.java:238)
 at org.apache.batik.bridge.UpdateManager.dispatchSVGLoadEvent(UpdateManager.java:220)
 at org.apache.batik.swing.svg.SVGLoadEventDispatcher.run(SVGLoadEventDispatcher.java:100)

 

The document loads without issue in Squiggle, so I know I'm messing something up.  Do I have to use the js.jar that comes with Batik?  Do I have to do something to "register" the js.jar to handle a certain script type?  I took a look through the Squiggle source, but didn't see anything that stood out.

Thanks for any help.

Michael
