Building ADF Taskflow for reuse

Hi All,

If you making taskflow for reuse either as jar or in portal and so on.Always make sure one property that Library Internal
This property makes an entry in task-flow-registry.xml and enable/disable taskflow to reuse.

Library Internal: This property controls the visibility of a task flow when packaged in an ADF library.
This helps developers to expose only those task flows that are indented for reuse.


if you check this property you will have task-flow-registry.xml as below

<?xml version = '1.0' encoding = 'UTF-8'?>
<task-flow-registry xmlns="">
 <task-flow-descriptor path="../../main/public_html/WEB-INF/testTaskFlow.xml" id="" type="" uses-page-fragments="false" library-internal="true" remote-invocable="false" train="false"/>


So always make sure you never check this property if you want to reuse.Or if you have parent taskflow and 5 sub taskflow which is called by parent taskflow then you can have 5 sub taskflow as
internal library but parent should be as internal library false.

Creating Data Control & Task flow in Webcenter Portal Builder

Prerequisite – Webcenter portal and Webcenter Spaces should be installed and there schemas as well.

Database should be installed in database. For this sample demo –I created sample tables in Webcenter schema .

You can connect to database using creating new connection

→ Please find attached script and execute in the database.

→ Open the link – http://localhost.silbury:8888/webcenter (Might be localhost for you)

→ Go to Shared Asset

→ Go to Data Control – Create

→ Click continue.

→ Select WebCenterDs – enter password- enter sql query as below in screenshot

→ Click Create.And make available for using in catalog .

→ Now Click on Taskflow -Create

→ Make task flow available

→ Click on Edit and Integration

→ Click open Data Control

→ Click Open EmployeeDC

→ Add Employee DC

→ Click On as Table

→ Click on default next and then create. Table will be there in Taskflow. Click Save then Close.

→. Now click on Portals on top Menu -< Create Portal

->Click Create

→ Click View your portal

→ Edit you page as below to add content

→ Click Open on UI components

→ Click Open On task Flows

→ Add Employees and save.

→ Click Save and then click on View Portal

→ This is final portal

→ Can Create more page like this.

→ If you want to navigate back to Data control or change query or add new task flow -click on edit page then Administer Portal

→ There you can edit data control and task flows.

Dynamic Taskflow with conditional activation

Use Case – How dynamic task flow activated conditionally.

Implementation – We have two ADF application .One is consumer application which have two task flow

Now we have consumer application which show no task flow on load.Task flow will be shown on click of button .If you click task flow 1 then tf1 will be called and vice versa.Till the button is clicked neither tf1, nor tf2 wud be executed.

Create Producer application-

Create an new ADF application. Create two new task flow as Sample1TF and Sample2TF as below –

Now in each task flow drag drop and view activity and Sample1PF in above screenshot.Same steps need to be done for Sample2TF. Drag drop again an view activity as Sample2PF.jsff

Sample2PF.jsff will be like this

Now project structure would be like

Now the deploy this project as ADF library jar.

Create Consumer Application –

Now we will be creating an consumer application. We will create an .jsff page with two button. Clicking on any button will called specific task flow.

We will drag drop region in the page and task id will be called .Binding of the page is as follow-

activation: Though you can specify values like conditional/deferred/active for this flag, in this post I discuss conditional activation. Setting activation=conditional, activates the ADF region if the EL expression set as a value for the task flow binding ‘active’ property(discussed below) returns true

active and task flow id will passed through an managed bean.Code of following bean as below

public class ProducerPocManagedBean {

private String taskFlowId = “/WEB-INF/com/sss/poc/Sample1TF.xml#Sample1TF”;

private Boolean activateRegion = Boolean.FALSE;

private RichRegion pocDynamicRegion;

public ProducerPocManagedBean() {


public TaskFlowId getDynamicTaskFlowId() {

return TaskFlowId.parse(taskFlowId);


public void setTaskFlowId(String taskFlowId) {

this.taskFlowId = taskFlowId;


public String getTaskFlowId() {

return taskFlowId;


public void setActivateRegion(Boolean activateRegion) {

this.activateRegion = activateRegion;


public Boolean getActivateRegion() {

return activateRegion;


public void loadTF1AL(ActionEvent actionEvent) {

// Add event code here…

activateRegion = Boolean.TRUE;

taskFlowId = “/WEB-INF/com/sss/poc/Sample1TF.xml#Sample1TF”;



public void loadTF2AL(ActionEvent actionEvent) {

// Add event code here…

activateRegion = Boolean.TRUE;

taskFlowId = “/WEB-INF/com/sss/poc/Sample2TF.xml#Sample2TF”;



public void setPocDynamicRegion(RichRegion pocDynamicRegion) {

this.pocDynamicRegion = pocDynamicRegion;


public RichRegion getPocDynamicRegion() {

return pocDynamicRegion;



Then drag drop this jsff into one .jspx page. That’s all .Now you can run the application. Following will be screenshot of the page.

Click on button Load TF1

Click on button Load TF2
