You can use a4j within RichFaces to return a JSON structure through an assync method calling.
Regarding a4j you can use the a4:jsFunction like follows:

<a4j:jsFunction 
		action="#{myBean.getListJson}" 
		data="#{myBean.list}"
		name="getListJson" 		
		oncomplete="printListJson(data)">

action: the method to call assync
data: a getter method defined at myBean (which returns the List parsed with JSONObject or JSONArray)
name: the name of the javascript function to call on your jsp
oncomplete: the javascript function that will receive the JSON data to be processed as you wish

I hope you can use Richfaces on your project, or newer JSF versions.
