EFW Function
The EFW function is established to call server events from JSP in AJAX. It is not necessary to send params or receive results when calling server events. The only thing you must do is send the event ID.
It is better to call the event in webSocket mode if it is a long-period one, and you can return several results in the event js.
Sample for JSP
<input type="button" value="Send" onclick="Efw('helloWorld_sendMessage')">
<input type="button" value="Send" onclick="Efw('helloWorld_sendMessage',true)">
