Disable Past dates and future dates in ADF Input Date

Hi all, In today's post i am going to explain you how to disable past date and future date for Input Date component. Sometime you get requiment to disable the past dates and future date also. This post can help you.

My requirement is to show only today and tomorrow's date and rest all need to disable. User should not select othere then these dates.
There are two attributes in inputDate component MinValue and MaxValue.

1. MinValue attribute is used to disable the back dates.

2. MaxValue attribute is used to disable the forward dates.

I have create one bean and two methods as show below

  private Date minDate = new Date();

    public Date getMaxDateVal() {
        Calendar cal = Calendar.getInstance();
        cal.setTime(new Date());
        cal.add(Calendar.DATE, 1); 
        return cal.getTime();


cal.add(Calendar.DATE, 1);  // how many forwarding dates need to enable, In my requirement i should show tomorrow date, sho i have mentioned "1".

    public Date getMinDate() {
    try {
                Calendar cal = Calendar.getInstance();
    java.util.Date date = cal.getTime();
    DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
                String currentDate = formatter.format(date);
    minDate = formatter.parse(currentDate);
    return formatter.parse(currentDate);
            } catch (Exception e) {
    return null;

jspx page code is  below.

 <af:inputDate label="Label 1" id="id1"

 Run the page.

Setting session scope variable to ADF BC View Object bind variable

In this post i am going to explain you how to set the session scope value to ADF BC View Object bind variable. Some times most of the View Objects will be based on some criteria and the bind variable value should based on specific user login. In this case follow the below steps.
Firstly I would like to thank for writing this post andrejusb post. But in this post he didn't describe about setting the session scope value to view object. If you have simillar requirement follow the below steps.

To set variable in session scope i have used the below code in the managed bean on button click. You can also use Managed bean which is in the session sope.

Now create bind variable in view object and set the expession shown below.

I used Department table here. Modify accordingly based on your use case.

Thanks :) and Happy Learning :)

Consume Secured web service using proxy client in ADF

In last post i have discussed about how to expose Business component as Secured service ADF BC as secured service.It is very common requirement to consume secured web service in ADF applications.In this post i am going to cover the same use case. Now i am going to consume the same service URL as Web Service proxy client in ADF.

Create fusion web application

Right click on model and go to the web service and select Web Service Proxy.

provide the web service URL

 Click on next and select the oracle/wss_username_token_client_policy

Finally Click on next and finish.

This will generate client java class to test the service method. Provide the credentials to service as shown below.

Thanks :) Happy Learning :)

Expose ADF BC as secured web service

Hello everybody, Today in this post i am going to explain you how to expose ADF Business components as Secured web service (Authentication and authorization).
Create fusion web application and create business components for Employee Table i.e, Entity Object, View Object and Application module.

Next create view criteria based on departmentid as shown below

Now go to application module and create service interface and make sure you select the view criteria as shown below

Next we need to add OWSM policies.

1. oracle/wss_username_token_service_policy (For authentication)
2. oracle/binding_permission_authorization_policy (For authorization)

Open the select "AppModuleServiceImpl" from the structure window and go to property inspector and add the security policies on security attribute.

add the below given security policies.

Now enable security on adf application, Authentication and authorization. In jazn-data.xml, Create user and application role "Managers" and assign the resource to the manager as shown below

You can manually add in jazn-data.xml file as given below
  <jazn-realm default="">

Only users whose role is managers can access the view Criteria method. For other users it throws authorization exception.
Deploy and then test the service in Webservice tester.

Thanks :) Happy Learning :)  NK

Custom Login in ADF Application

We have used ADF security many more time with form based Authentication and Authorization using default login.html and error.html.
Suppose if we want to design our own login.jspx page and have complete control on ADF authentication then follow these steps.

1. Create Login.jspx and update the web.xml with login.jspx.

2. In login.jspx  add two input text with name (User name and password) and one button create managed bean  and  bind the input text with managed bean use the below code on button action event.

3. Add the following 3 jars in view controller project library


import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;

import javax.servlet.RequestDispatcher;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;



    public void executeLogin(ActionEvent actionEvent) {
        FacesContext ctx = FacesContext.getCurrentInstance();
        HttpServletRequest request =
        Subject mySubject;
        try {
            mySubject = Authentication.login(new URLCallbackHandler(uid.getValue().toString(), pwd.getValue().toString()));
            ServletAuthentication.runAs(mySubject, request);
            String loginUrl =
            HttpServletResponse response =
            RequestDispatcher dispatcher =
            dispatcher.forward(request, response);
        } catch (FailedLoginException e) {
            FacesMessage msg =
                new FacesMessage(FacesMessage.SEVERITY_ERROR, "Invalid username or password",
                                 "Invalid username or password");
            ctx.addMessage(null, msg);
        } catch (Exception e) {

MAF: Data Control method returns Custom Type as array

In my previous post i have discussed about the Call Data control method from managed bean which return the Integer/String or and primitive data type.

But if your Data control method returns the Array of Custom data type Like Employees,Department etc. Use below code.

findEmployeesInDept is data control method which returns array of employees.

        pnames = new ArrayList();
        params = new ArrayList();
        ptypes = new ArrayList();
        //end - WS empty params

        List l = new ArrayList();
            GenericType result = (GenericType)AdfmfJavaUtilities.invokeDataControlMethod("HRDC", null, "findEmployeesInDept",pnames, params, ptypes);
                for (int i = 0; i < result.getAttributeCount(); i++) 
                    GenericType r = (GenericType)result.getAttribute(i);
                    Employees wd = (Employees)GenericTypeBeanSerializationHelper.fromGenericType(Employees.class, r);
        catch (AdfInvocationException e) 

Happy Learning.

        } catch (AdfException e) {


Call Data Control method from managed bean in MAF

If you have requirement to call the Data Control method from managed bean, Use AdfmfJavaUtilities.invokeDataControlMethod(). Below is complete code

Data Control method name is calculateDays with three argument of String type. In below method "iHCMWSClient" (name of the data control).

        List pnames1 = new ArrayList();
        List params1 = new ArrayList();
        List ptypes1 = new ArrayList();

        pnames1.add("arg0"); //start date

        pnames1.add("arg1"); //endDate

        pnames1.add("arg2"); //personID
        params1.add(new AbsenceRequest().getpID());

        System.out.println("%%%%% result" + noOfDays);
        try {
            noOfDays =
                    (String)AdfmfJavaUtilities.invokeDataControlMethod("iHCMWSClient", null, "calculateDays", pnames1, params1, ptypes1);

    System.out.println("%%%%% result" + noOfDays);
        } catch (AdfInvocationException e) {
            throw new AdfException("error ", AdfException.ERROR);

Calling Java Script function from java bean class in MAF


Sometimes you may get requirement to call javascript function from bean class, Use below invokeContainerJavaScriptFunction() to call the Javascript function.

doAlert() is JS function with one argument.

                AdfmfContainerUtilities.invokeContainerJavaScriptFunction("com.ihcmMobile.Absence", "doAlert",
                                                                          new Object[] { " Absence Record Already Exist " });

JS Function:

doAlert = function () {
        var args = arguments;
        var str = ""+ args[0];
        alert(str);  //Absence Record Already Exist  gets printed


Error while deploying MAF app to android - Cannot run program "\sdk\tools\zipalign"


If you are getting the below error while deploying the application to android. Here is the solution

[11:11:31 AM] Cannot run program "\sdk\tools\zipalign"": CreateProcess error=2, The system cannot find the file specified
[11:11:31 AM] CreateProcess error=2, The system cannot find the file specified

During the deployment jdeveloper creates .apk file using zipalign.exe file. But zipaling.exe is not exist in this location C:\Program Files\Android\sdk\tools\zipalign.

Solution is copy the zipaling.exe from   \build-tools\19.1.0  to \sdk\tools folder.

Convert input text Content to Upper Case or Lower Case

In this post i am going to talk about converting lower case data to upper case (or Upper Case data to Lower Case). There are multiple solutions to achieve this but i am showing there different methods.

1. you can use contentStyle="text-transform:uppercase;" on input text field.
2. Using java script code

<af:resource type="javascript">
      function convertToUpperCase(evt){
        var field = evt.getCurrentTarget();
        var fieldVal= field .getSubmittedValue();
        field .setValue(fieldVal.toUpperCase());        

 <af:inputText label="Label 1" id="it1">
                <af:clientListener method="convertToUpperCase" type="valueChange"/>

3. You can create class with accessors and use toUpperCase() of String class

    public void setFirstName(String value) {
        setAttributeInternal(FIRSTNAME, value.toUpperCase());

Thanks :) Happy Learning :)

Passing Parameters to Taskflow

Hi friends today i am going to post about the passing parameters to Task flow. I have seen most of the developers facing problem in passing parameter to TF.
I have created Business components on Employees table. I have added where clause to the query as shown below and bind variable.

Create custom method in class which is used to filter the employees based on DepartmentId

Now create one BoundedTF (employeeTF) and add the custom method (default activity) and view activity to show the list of employees as table.

Go to overview tab --> parameters --> set the parameter as shown below

Now go to adfc-config.xml file and drag and drop view activity and employeeTF.
Double click on view activity and generate the main.jspx page and drag & drop InputText and button as shown below to pass department ID.

Select the EmployeesTF go to property inspector and pass the value to DeptID #{pageFlowScope.deptID}

Now create bindings for input text and action listener method for button of main.jspx page and set the class to backingBeanScope. Use the below code to set the value in pageFlowScope.

    public void executeDeparment(ActionEvent actionEvent) {
        // Add event code here...
        AdfFacesContext.getCurrentInstance().getPageFlowScope().put("deptID", deptid.getValue().toString());

Now run the page
