Yes , you could do like this :
template:
<span id="test" onclick="rpcFunction();"/>
<script>
rpcFunction() {
var yourUrl=${urlFromClass}
.....
}
</script>
component class :
@Inject
private ComponentResources resources;
public String getUrlFromClass() {
return resources.createActionLInk("rpcTrigger",false).toString();
}
StreamResponse onRpcTrigger() {
//build your json object and wrapp it in a StreamResponse
return streamResponse;
}
hope i haven't forgot anything.

Sounds interesting. I looked at component events. Are you saying that you
can
invoke a component action based on a javascript event such as "mouseDown"?
To me it seems that you can only invoke based on a submit action. I want
the
UI, through AJAX, to talk to some service and get JSON data back. The URL
to
the json data could be as simple as a link to a jsp that creates the json
data string.
When I meant jsonrpc-bridge I meant the specific open source
implementation
