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…… 🙂
