Calling Server side methods from JavaScript in ADF 11g.

The following example explains , how to call the server side methods (Backing Bean / Managed Bean methods) from Java Script.

Sample requirement is :

When we call the JavaScript for validation  / Java Script values after that we want to pass the control to service side methods with arguments or with out.

here we can define the code .

In UI (jsff/ jspx pages)

define the client listener and server listener tag for any component it supports in ADF 11g like:




the logic works like , first it will call the JavaScript method , once it completes all the code it will navigate to server listener.

JavaScript Method defintion:

function sampleJSMethod(evt) {

    AdfCustomEvent.queue(evt.getSource(), "sampleServerSideMethod",
    {argumentName: argumentValueFromJS},true);

    evt.cancel();
  }

ServerSide Method Defintion:


    public void sampleMethod(ClientEvent clientEvent) {
        Object value = (Object)clientEvent.getParameters().get("argumentName");
    }


This facility we can use in real time , whenever we have to pass some values to Java Script functions , after depending on that return values if we need to run Service Side Method.
