Ashish Awasthi's Blog: Information

Hello All,
This is post is about getting browser details (version, name ) , platform details (Operating System details) ,server and client IP addresses in Oracle ADF Application
sometimes we need these small but important details -

Code to get this information-

        RequestContext requestCtx = RequestContext.getCurrentInstance();
        Agent agent = requestCtx.getAgent();
        String version = agent.getAgentVersion();
        String browser = agent.getAgentName();
        String platform = agent.getPlatformName();
        String platformVersion = agent.getPlatformVersion();
        FacesContext fctx = FacesContext.getCurrentInstance();
        HttpServletRequest request = (HttpServletRequest) fctx.getExternalContext().getRequest();
        StringBuilder detailMsg = new StringBuilder("<html><body><b>Browser Agent and Ip address details</b><br>");
        detailMsg.append("<ul><li><b>Browser-</b>" + browser + "</li><li><b>Version-</b>" + version +
                         "</li><li><b>Plateform-</b>" + platform + "</li>");
        detailMsg.append("<li><b>Plateform Version-</b>" + platformVersion + "</li><li><b>Server IP-</b>" +
                         request.getLocalAddr() + "</li><li><b>Client IP-</b>" + request.getRemoteAddr() +
                         "</li></ul>");
        detailMsg.append("</body></html>");
        FacesMessage errMsg = new FacesMessage(detailMsg.toString());
        errMsg.setSeverity(FacesMessage.SEVERITY_INFO);
        fctx.addMessage(null, errMsg);

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-

Very simple to use
Date Listener support
Fetch weather data for all stations of country
can be used with desktop or web application
Ajax supported
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-
