Custom Error Handling ADF Screen using Java Code ( Oracle BPM 11g ) Taskflow

Custom Error Handling ADF Screen using Java Code ( Oracle BPM 11g ) Taskflow



   Most of the time try and catch block used in java code to handle error, but in terms of customer view Exception page has to be show in-order to avoid panic. Use below method and call any were from Catch block.


     import oracle.adf.controller.ControllerContext;

    ControllerContext controllerCtx = null;
    
   public  void setRedirectPageMethod(String custmMessage ,String StackTraceMessage) {
  
    FacesContext fcntx = FacesContext.getCurrentInstance();
    ExternalContext ectx = fcntx.getExternalContext();
    String viewId = "/faces/CustomErrorPage_Form.jspx";
    controllerCtx = ControllerContext.getInstance();
    String activityURL = controllerCtx.getGlobalViewActivityURL(viewId);
    try{
      ectx.redirect(activityURL);
         
    }
    catch(Exception e) {

    }
}

import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.binding.BindingContainer;
 

public void exitBPMWorkflow(){
    
             String returnMessage = null;
             try {
                 
              DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
                 OperationBinding operationBinding = (OperationBinding)bindings.getOperationBinding("SUBMIT");
                 Map paramsMap = operationBinding.getParamsMap();

                 paramsMap.put("DC_OPERATION_BINDING", "bindings.SUBMIT");
                 operationBinding.execute();
                 List errorsOnSubmit = operationBinding.getErrors();
                 if (errorsOnSubmit == null || errorsOnSubmit.isEmpty()) {
                     returnMessage = "closeTaskFlow";
                     FacesContext facesContext = FacesContext.getCurrentInstance();
                     ExtendedRenderKitService service = Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);
                     service.addScript(facesContext, "window.opener = self;window.close();");
