How to call JavaScript from a ADF Managed Bean

To run a JS function from our Managed Bean, first put the JS code in a <af:resource> component in our JSF page:

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
           xmlns:f="http://java.sun.com/jsf/core"
           xmlns:pe="http://xmlns.oracle.com/adf/pageeditor"
           xmlns:cust="http://xmlns.oracle.com/adf/faces/customizable"
           xmlns:af="http://xmlns.oracle.com/adf/faces/rich">

<af:resource type="javascript">
    function myFunc() { [ any JS code ] };
</af:resource>

In the managed bean, put the following code in the appropriate method (e.g. in a action listener if we want to execute the JS code after a commandButton or commandLink is selected):

import javax.faces.context.FacesContext;
import org.apache.myfaces.trinidad.render.ExtendedRenderKitService;
import org.apache.myfaces.trinidad.util.Service;

[…]

FacesContext facesContext = FacesContext.getCurrentInstance();
ExtendedRenderKitService service = (ExtendedRenderKitService) org.apache.myfaces.trinidad.util.Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);
service.addScript(facesContext, "myFunc();");
