Requirement – Calling a method on page load at render response time for jsf fragment in oracle ADF

Solution – Alright. Few of ADF guys will say, use pagePhaseListener is answer. Well , you are not right .pagePhaseListener is work only in jspx , not in jsff. 🙁 . As i already written about
pagePhaseListener in jspx here – invoke method on page load for jspx

Ok, we will use regionController,We will create a bean which implement regionController.

Create a bean which implements RegionController.

package com.techartifact.hte.bean.audittrailall;
 
import java.util.Map;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;
 
import oracle.adf.model.RegionBinding;
import oracle.adf.model.RegionContext;
import oracle.adf.model.RegionController;
 
import org.apache.myfaces.trinidad.render.ExtendedRenderKitService;
import org.apache.myfaces.trinidad.util.Service;

public class AuditTrailAllAppPhaseListener implements RegionController{
    public AuditTrailAllAppPhaseListener() {
        super();
    }
    
    public boolean refreshRegion(RegionContext regionContext)   // you need to override refresh region method.
    {
        int refreshFlag= regionContext.getRefreshFlag();
        FacesContext fctx = FacesContext.getCurrentInstance();
        //check internal request parameter
        Map requestMap = fctx.getExternalContext().getRequestMap();
        PhaseId currentPhase=(PhaseId)requestMap.get("oracle.adfinternal.view.faces.lifecycle.CURRENT_PHASE_ID");   
        if(currentPhase.getOrdinal()==PhaseId.RENDER_RESPONSE.getOrdinal())   // write custom logic of correct lifecycle phase.
        {
            Object showPrintableBehavior =
            requestMap.get("oracle.adfinternal.view.faces.el.PrintablePage");
            if (showPrintableBehavior != null)
            {
                if (Boolean.TRUE == showPrintableBehavior) 
                {
                ExtendedRenderKitService erks = null;
                erks =
                Service.getRenderKitService(fctx, ExtendedRenderKitService.class);
                //invoke JavaScript from the server
                erks.addScript(fctx, "window.print();");
                erks.addScript(fctx, "window.close();");
                    
                }
           }
                regionContext.getRegionBinding().refresh(refreshFlag);
        }
    return false;
    }
     
    public boolean validateRegion(RegionContext regionContext) 
    {
        regionContext.getRegionBinding().validate();
        return false;
    }
     
    public boolean isRegionViewable(RegionContext regionContext) 
    {
     return regionContext.getRegionBinding().isViewable();
    }
     
        public String getName() 
        {
        return null;
        }
 }

Ok , then you need to register this class file in jsff page definitoon file using controllerClass like below –

<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"
                version="11.1.1.61.92" id="audit_trail_allPageDef"
                ControllerClass="com.techartifact.hte.bean.audittrailall.AuditTrailAllAppPhaseListener"
                Package="com.techartifact.hte.pages.audittrailall">
  <parameters/>
  <executables>

That is all .Now run your page.you can write your java code on page code,in my case i call some javascript..

Happy coding with Vinay kumar in techartifact…… 🙂
