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
• To use this in web application , you must handle SSL certificate

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-

Download file from url using Oracle ADF & Java- Download Manager

In this tutorial i will show you how to download a file from its url (web)-
as- http://www.tutorialspoint.com/java/java_tutorial.pdf
This will work as a simple download manager, you can add file url to download it and save it.
This tutorial makes use of FileHandling and java.net.URL class in java.

• User Interface is very simple to design as it have only one input text and one button, so create a fusion web application , and a bounded taskflow with a page fragment in it
• Now drag a Input text to enter url and a button to perform action on it from Componenet palette .
• Bind input text to bean to get its value from page



 private RichInputText fileUrlBind;

    public void setFileUrlBind(RichInputText fileUrlBind) {
        this.fileUrlBind = fileUrlBind;
    }

    public RichInputText getFileUrlBind() {
        return fileUrlBind;
    }

• Now create actionListener to managed bean and write code for downloading file from given url- see code



    public void DownloadFileButton(ActionEvent actionEvent) {
        try {
            if (fileUrlBind.getValue() != null) {
                String fileUrl = fileUrlBind.getValue().toString();
                if (fileUrl.startsWith("http://")) {
                    String msgNm = fileUrl.substring(7);

                    cnctmsgBind.setValue("Connecting to " + msgNm + "....");

                    URL url = new URL(fileUrl);
                    url.openConnection();
                    InputStream reader = url.openStream();


                    FileOutputStream writer =
                        new FileOutputStream("C:/javadrive." + fileUrl.substring(fileUrl.lastIndexOf(".")));
                    byte[] buffer = new byte[153600];
                    int totalBytesRead = 0;
                    int bytesRead = 0;

                   
                    dwnldMsgBind.setValue("Reading file 150KB blocks at a time");
                    while ((bytesRead = reader.read(buffer)) > 0) {
                        writer.write(buffer, 0, bytesRead);
                        buffer = new byte[153600];
                        totalBytesRead += bytesRead;
                    }
                 
                    alerMsgBind.setValue("File is downloaded successfully, look at your c drive :-)");
                    writer.close();
                    reader.close();
                } else {
                    FacesMessage errMsg = new FacesMessage("Something went wrong");
                    errMsg.setSeverity(FacesMessage.SEVERITY_ERROR);
                    errMsg.setDetail("Example- http://www.javadrive.co.in/java.pdf");
                    FacesContext context = FacesContext.getCurrentInstance();
                    context.addMessage(fileUrlBind.getClientId(), errMsg);
                }
            }
        } catch (MalformedURLException e) {
            FacesMessage errMsg = new FacesMessage("Something went wrong");
            errMsg.setSeverity(FacesMessage.SEVERITY_ERROR);
            FacesContext context = FacesContext.getCurrentInstance();
            context.addMessage(null, errMsg);
            e.printStackTrace();
        } catch (IOException e) {
            FacesMessage errMsg = new FacesMessage("Something went wrong");
            errMsg.setSeverity(FacesMessage.SEVERITY_ERROR);
            FacesContext context = FacesContext.getCurrentInstance();
            context.addMessage(null, errMsg);
            e.printStackTrace();
        }


    }
