Send WhatsApp messages from Oracle ADF Application

 Hello Everyone

In this post, I am sharing a method to send WhatsApp messages from Oracle ADF Application using the "WhatsApp Click to Chat" feature as WhatsApp doesn't provide any official API.

Though it's an extremely simple way and we need not write a single line of code, We just need to pass some values in an URL to open WhatsApp Click to Chat console.

Created an ADF Application and a page in the view controller with two text fields and a button in it. It looks like this

and both fields are bonded to the managed bean variables

1. <af:inputText label="Mobile No." id="it1" value="#{viewScope.SendWhatsAppBean.mobileNo}"
2. autoSubmit="true"/>
3. <af:inputText label="Message" id="it2" rows="2" value="#{viewScope.SendWhatsAppBean.message}"
4. autoSubmit="true"/>

and managed bean just contain simple POJO variables

1. package sendwhatsappadf.view.bean;
4. public class SendWhatsAppBean {
5. public SendWhatsAppBean() {
6. }
8. private String mobileNo;
9. private String message;
11. public void setMobileNo(String mobileNo) {
12. this.mobileNo = mobileNo;
13. }
15. public String getMobileNo() {
16. return mobileNo;
17. }
19. public void setMessage(String message) {
20. this.message = message;
21. }
23. public String getMessage() {
24. return message;
25. }
26. }

Next is to know about the browser-based WhatsApp click to chat feature, It makes use of an API URL

https://api.whatsapp.com/send?phone=&text=

Now on button click, we can pass phone number and text message in this URL to open click to chat console and in ADF we can do this using destination property of af:button.

1. <af:button text="Send" id="b1" targetFrame="_blank"
2. destination="https://api.whatsapp.com/send?phone=#{viewScope.SendWhatsAppBean.mobileNo}&amp;text=#{viewScope.SendWhatsAppBean.message}"
3. partialTriggers="it2 it1"/>

In the above XML source, we can see that both values are passed from managed bean variables.

Now run and check the application. Enter mobile no., text message on the page

On click of the Send button, WhatsApp click to chat console is opened in a new browser window.

and this button will open the WhatsApp QR code scanner window, In that window scan QR code with your phone and start sending messages.

Using this method we can pass values from ADF bindings to WhatsApp URL and send messages from ADF application.

Send SMS from Oracle ADF Application using Horizon SMS API

This post is about using SMS API to send SMS text to mobile from an Oracle ADF application
there are various SMS Gateway to send SMS using java and all java API's can be used with Oracle ADF

here i am using sms horizon (a bulk sms provider in india) see this SMS API integration with Java and Oracle ADF, follow the steps
First create an account with SMS Horizon - http://www.smshorizon.in/ or User Login- SMS Horizon

you can purchase a trial package to test your code, they provide 200 sms for Rs 25 only. So After purchasing trial pack you will get and API Key and username



Login to your account and see your dashboard-

you will see your API key in this type of box-

Now first step is complete and second and last step is implement code in your managed bean
you can find Sample API files (code to use API in Java, C#, PHP etc) from there

So for this i have a created a Fusion Web Application and a page in it

created a managed bean and actionListener for this Send button
this url is used to send sms and it returns msgId of sent message

http://smshorizon.co.in/api/sendsms.php?user=******&apikey=*****8&mobile=xxyy&message=xxyy&senderid=xxyy&type=txt

 

See the ActionListener code -

    /**Method to send SMS using SMS Horizon API
     * @param actionEvent
     */
    public void sendSMSAction(ActionEvent actionEvent) {
        // get mobile number value using component binding
        if (mobNoBind.getValue() != null) {
            // Replace with your username
            String user = "userId";

            // Replace with your API KEY (We have sent API KEY on activation email, also available on panel)
            String apikey = "your_api_key";

            // Replace with the destination mobile Number to which you want to send sms
            String mobile = mobNoBind.getValue().toString();

            // Replace if you have your own Sender ID, else donot change
            String senderid = "WEBSMS";

            // Replace with your Message content
            String message = "SMS API -Oracle ADF";

            // For Plain Text, use "txt" ; for Unicode symbols or regional Languages like hindi/tamil/kannada use "uni"
            String type = "txt";

            //Prepare Url
            URLConnection myURLConnection = null;
            URL myURL = null;
            BufferedReader reader = null;

            //encoding message
            String encoded_message = URLEncoder.encode(message);

            //Send SMS API
            String mainUrl = "http://smshorizon.co.in/api/sendsms.php?";

            //Prepare parameter string
            StringBuilder sbPostData = new StringBuilder(mainUrl);
            sbPostData.append("user=" + user);
            sbPostData.append("&apikey=" + apikey);
            sbPostData.append("&message=" + encoded_message);
            sbPostData.append("&mobile=" + mobile);
            sbPostData.append("&senderid=" + senderid);
            sbPostData.append("&type=" + type);

            //final string
            mainUrl = sbPostData.toString();
            System.out.println("URL to Send SMS-" + mainUrl);
            try {
                //prepare connection
                myURL = new URL(mainUrl);
                myURLConnection = myURL.openConnection();
                myURLConnection.connect();
                reader = new BufferedReader(new InputStreamReader(myURLConnection.getInputStream()));
                //reading response
                String response;
                while ((response = reader.readLine()) != null) {
                    //print response
                    System.out.println(response);
                }
                System.out.println(response);
                //finally close connection
                reader.close();


            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    public void setMobNoBind(RichInputText mobNoBind) {
        this.mobNoBind = mobNoBind;
    }

    public RichInputText getMobNoBind() {
        return mobNoBind;
    }

you can check status of each SMS in your account that it is delivered of not, other than this you can also check status of msg in your code also using this url

http://smshorizon.co.in/api/status.php?user=*****&apikey=*********&msgid=xxyy

pass msgId returned from previous url and it will return you status of message as- PENDING , DELIVERED etc
see imports used in code-

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;

import javax.faces.event.ActionEvent;

import oracle.adf.view.rich.component.rich.input.RichInputText;
