Java Development Tools

Hi Timo,

While I was going through a document of Frank - Configuring a clientListener  and serverListerner at runtime ...

we are adding the event and method name such as - 

cls.addListener("keyUp","clientMethodCall");  

But how to dynamically add JavaScript to the page using the extended renderkit service?

I mean how can we add the JavaScript method - "clientMethodCall" from the bean?

Thanks
