Fetch Tweets of a User using Twitter4J API and show in af:table in ADF & Java

In the previous blogs we learned about posting tweets on twitter timeline using Twitter4J API and sending direct meaages to followers using same API

This post is next in the series and about fetching a user tweets and showing in ADF Table , For this requirement we need to use same Consumer Key+ Secret and Access Token+Secret (Refer previous posts for this)

And In same way after authentication we can fetch a user tweets by using it's twitter handle. So for this requirement I have added a button to fetch tweets and a POJO based table to show fetched tweets in page

See the code to fetch tweets using user's twitter handle and it's retweets and favourites count, We can get tweets by passing page number as parameter and it returns a list of tweets

Send Direct Message to followers using Twiter4J API in Oracle ADF and Java

My previous post was about tweeting using Twitter4J API from Oracle ADF Application . Twitter4J is a Java API that simplifies accessting twitter features in our application easily

In this I am going to show how to send DM (Direct Message) to anyone using their twitter handle and for this we need to use same consumer key, secret and access token, secret (How to access all these is described in previous post)

In this post I am talking about how to access Facebook profile detail using restfb graph API . So First we need to know about Acsess Tokens

Send eMail and attachement from any SMTP server using JavaMail in Oracle ADF

The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications- JavaMail API

This post is about sending eMail and attachments from any SMTP (Simple Mail Transfer Protocol) as Gmail or any other server (mail.awasthiashish.com)
You can read my previous post about mail integration with ADF that was specifically about using Gmail Server
Gmail Integration with Oracle ADF using Java Mail API 

So all basic configuration is described in previous post , now in this post i am only writing a java method to send mail and attachments


Don't forget to download these 2 jar files

Using captcha with ADF Faces (Integrate Kaptcha project with Oracle ADF)

First of all wishing a very Happy New Year to all of you, learn more n more ADF this year :)

This post is about using captcha challenge in ADF Faces, captcha is used to determine whether user is a human or not
CAPTCHA stands for-Completely Automated Public Turing test to tell Computers and Humans Apart
Frank Nimphius posted about 'captcha with ADF Faces' using "Simple Captcha" project.
You can read complete article- http://www.oracle.com/technetwork/developer-tools/jdev/captcha-099103.html



For this post I am using modern version of simplecaptcha project called Kaptcha, project provides a servlet that is responsible for generating captcha image and there are various configuration parameters to change look n feel of captcha image
See project documentation - https://code.google.com/p/kaptcha/
Download jar file- https://code.google.com/p/kaptcha/downloads/list

Now see the steps to integrate Kaptcha project with Oracle ADF

• Create a FusionWeb Application, attach kaptcha-2.3.2 jar to viewController project, also see How to use "Kaptcha"-https://code.google.com/p/kaptcha/wiki/HowToUse





• Next step is to add kaptcha servlet reference in web.xml file



 <servlet>
        <servlet-name>Kaptcha</servlet-name>
        <servlet-class>com.google.code.kaptcha.servlet.KaptchaServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Kaptcha</servlet-name>
        <url-pattern>/kaptchaimage</url-pattern>
    </servlet-mapping>



• Add an af:image on page to show captcha, image source is referenced from servlet mapping



<af:image id="i1" partialtriggers="l1" shortdesc="Captcha" source="/kaptchaimage">



• Default configuration for captcha image is completed , I have added an af:inputText and button on page to enter captcha result .



<af:panelBox text="Captcha Demo- www.awasthiashish.com" id="pb1" showDisclosure="false"
                                 inlineStyle="width:350px;">
                        <f:facet name="toolbar"/>
                        <af:spacer width="0" height="10" id="s3"/>
                        <af:panelFormLayout id="pfl1">
                            <af:panelGroupLayout id="pgl1" layout="horizontal">
                                <af:image source="/kaptchaimage" id="i1" partialTriggers="l1" shortDesc="Captcha"/>
                                <af:spacer width="10" height="0" id="s4"/>
                                <af:link id="l1" icon="#{resource['images:reload.png']}" shortDesc="Refresh Captcha"/>
                            </af:panelGroupLayout>
                            <af:inputText label="Enter text" id="it1" binding="#{ReadCaptchaBean.entrdCaptchaBind}"
                                          contentStyle="font-weight:bold;"/>
                            <af:button text="Submit" id="b1" actionListener="#{ReadCaptchaBean.readCaptchAction}"/>
                        </af:panelFormLayout>
                    </af:panelBox>



• Run application and see how captcha image is appearing on page





• It looks good :-), now see the managed bean code written in submit button's action. This code checks actual captcha value with entered value



    //Binding of inputText to get entered value
    private RichInputText entrdCaptchaBind;

    public void setEntrdCaptchaBind(RichInputText entrdCaptchaBind) {
        this.entrdCaptchaBind = entrdCaptchaBind;
    }

    public RichInputText getEntrdCaptchaBind() {
        return entrdCaptchaBind;
    }
    
    /**Method to check whether entered value is correct or not
     * @param actionEvent
     */
    public void readCaptchaAction(ActionEvent actionEvent) {
        FacesContext fctx = FacesContext.getCurrentInstance();
        ExternalContext ectx = fctx.getExternalContext();
        HttpServletRequest request = (HttpServletRequest) ectx.getRequest();
        //KAPTCHA_SESSION_KEY- The value for the kaptcha is generated and is put into the HttpSession. This is the key value for that item in the session.
        String kaptchaExpected =
            (String) request.getSession().getAttribute(com.google.code.kaptcha.Constants.KAPTCHA_SESSION_KEY);
        //Get entered value of captcha using inputText binding
        String kaptchaReceived = entrdCaptchaBind.getValue().toString();
        System.out.println("Entered Value-" + kaptchaReceived + " Expected Value-" + kaptchaExpected);
        if (kaptchaReceived == null || !kaptchaReceived.equalsIgnoreCase(kaptchaExpected)) {
            FacesMessage errMsg = new FacesMessage("Invalid Value");
            errMsg.setDetail("Incorrect captcha value- Not Human");
            errMsg.setSeverity(FacesMessage.SEVERITY_ERROR);
            fctx.addMessage(entrdCaptchaBind.getClientId(), errMsg);
        } else {
            FacesMessage errMsg = new FacesMessage("Correct Value");
            errMsg.setDetail("Hello this is the right guess");
            errMsg.setSeverity(FacesMessage.SEVERITY_INFO);
            fctx.addMessage(entrdCaptchaBind.getClientId(), errMsg);
        }
    }



• Again run this application and enter value for captcha








• So it is working , now to change captcha image added a link with partialSubmit=false and set partial trigger property on af:image.





• Kaptcha integration with Oracle ADF is complete and it is working properly  now if you want to modify captcha look n feel then add some init-param (configuration parameter) in web.xml file.
  See complete list of configuration parameters- https://code.google.com/p/kaptcha/wiki/ConfigParameters
  I have changed some parameters value in web.xml , see changed source of web.xml and captcha output

Download-Sample 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;

Creating pdf file using Apache PDFBox API in ADF Faces and opening it in new window -Oracle ADF

Apache PDFBox library is an open source java tool for working with PDF documents, go to http://pdfbox.apache.org/ for API docs and download jar (pdfbox-app-1.8.2) from there.

•  Now create a fusion web application and add jar to view controller project's library and class-path

•  To convert text to pdf format, i have used an input text and bind it to bean (to get value)

•  Now see the button code that converts text to pdf file format using Apache PDFBox



        PDDocument document = new PDDocument();
        PDPage page = new PDPage();
        document.addPage(page);

        // Create a new font object selecting one of the PDF base fonts
        PDFont font = getFontDef();

        // Start a new content stream which will "hold" the to be created content
        PDPageContentStream contentStream = new PDPageContentStream(document, page);

        // Define a text content stream using the selected font, moving the cursor and drawing the text "Hello World"

        contentStream.beginText();
        contentStream.setFont(font, 10);
        contentStream.moveTextPositionByAmount(50, 700);
        contentStream.drawString(textToConvert.getValue().toString());
        contentStream.endText();

        // Make sure that the content stream is closed:
        contentStream.close();

        // Save the results and ensure that the document is properly closed:
        try {
            document.save("D:/Test_pdf.pdf");
        } catch (COSVisitorException e) {
        }
        document.close();

Bing language Translation API integration with Java- microsoft-translator-java-api

Google Translation is very popular and widely used for language translation as it is now paid service,
so i  came to know about Microsoft Translator (Bing Translator), it is providing free API up to 2000,000 character/Month to translate.

Key features and point-

• Provides java wrapper around microsoft translator (Bing Translator)
• Developed as alternative of Google Translator
• Follow coding standard, naming, functionality and usage patterns of widely used google translation API

This is very very simple to use -Follow steps

• First Download JAR for API- http://code.google.com/p/microsoft-translator-java-api/  with all dependencies
• Now obtain client secret key and client id in order to access API , see this http://msdn.microsoft.com/en-us/library/hh454950.aspx
• After this create a simple java class and just write this code-
• Don't forget to add JAR in your project's class path



package translation;

import com.memetix.mst.language.Language;
import com.memetix.mst.translate.Translate;

public class MicrosoftTranslator {
    public static void main(String[] args) throws Exception {
        
        Translate.setClientId("secret client id");
        Translate.setClientSecret("secret key");


        String translatedText = Translate.execute("hello", Language.ENGLISH, Language.FRENCH);
        System.out.println(translatedText);
    }
}



• Enter your key and id in code, you can change language with available list, and run this code

Using Java API for getting Weather information in Oracle ADF-wunderground-core

hello everyone, here is nice tutorial for all ADF techies-

i have developed an application in ADF that retrieves weather information of a country's weather stations.

as-temperature, humidity, dew, rain rate, wind speed etc using wunderground-core 

API . This API fetch weather data for a weater station by given month and year or data for all the stations of a country.

Feature of this wunderground-core-

1. Very simple to use
2. Date Listener support
3. Fetch weather data for all stations of country
4. can be used with desktop or web application
5. Ajax supported
6. Real Time weather values

Snap-

 Change Country-

Download wunderground-core API- https://code.google.com/p/wunderground-core/downloads/list

and download jar distribution with all dependencies

• Now start , create a fusion web application and add jar file to  classpath

• Now create a bounded taskflow and a .jsff page inside this , now see the simple code to get all weather station of acountry and their weather data



        /*  create an instance of WeatherStationService */
        WeatherStationService weatherStationService = new WeatherStationService();

        /*  find all weather stations */
        List<WeatherStation> stations = weatherStationService.findAllWeatherStationsByCountry("INDIA");

        
        for (WeatherStation weatherStation : stations) {
            System.out.println(weatherStation.getStationId() + "\t" + "\t" + weatherStation.getCity() + "\t" +
                               weatherStation.getCountry());

            HttpDataReaderService dataReader = new HttpDataReaderService();
            dataReader.setWeatherStation(weatherStation);
            DataSet current = dataReader.getCurrentData();

            System.out.println(current.getDateTime() + "Temperature- " + current.getTemperature() + "Humidity-" +
                               current.getHumidity());



• I have used this code on my af:commandButton for getting weather data, and a table on page to show this information on page using list (arrayList) , rest is same and simple like other ADF Application
• Download Sample Application and see it, you will also learn that how to show a table using List(Java) Sample ADF Application





• See source of .jsff page for tables'use and values-
