Issue in developing UDF

[Nirav Shah]

Hi ,


I am trying to extract info from user agent using WURFL libraries.

I am not sure what's wrong I am doing here but it's not working and not
giving any errors as well.

I have put wurfl.xml in source folder and  wurfl<version>.jar to
/jar/3rdparty/

*Code :*

        wurfl = new
net.sourceforge.wurfl.core.GeneralWURFLEngine("wurfl.xml");
            String SUA =
org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.toStringFromUTF8(userAgent.start,
userAgent.end, userAgent.buffer);


            String[] capabilities = {
                    "device_os",
                    "device_os_version",
                    "is_tablet",
                    "is_wireless_device",
                    "pointing_method",
                    "preferred_markup",
                    "resolution_height",
                    "resolution_width",
                    "ux_full_desktop",
                    "xhtml_support_level",
                    "is_smarttv",
                    "can_assign_phone_number",
                    "brand_name",
                    "model_name",
                    "marketing_name",
                    "mobile_browser_version"
                };
            wurfl.setEngineTarget(EngineTarget.accuracy);
            wurfl.setCapabilityFilter(capabilities);
            Device device = wurfl.getDeviceForRequest(SUA);
            System.out.println("4-->"+new Date(
System.currentTimeMillis()));
            System.out.println("Device OS: " +
device.getCapability("device_os"));
            System.out.println("Device OS version: " +
device.getCapability("device_os_version"));
            System.out.println("Brand name: " +
device.getCapability("brand_name"));
            System.out.println("advertised_device_os_version: " +
device.getCapability("advertised_device_os_version"));
            System.out.println("advertised_device_os: " +
device.getCapability("advertised_device_os"));
            System.out.println("advertised_browser: " +
device.getCapability("advertised_browser"));

System.out.println("advertised_browser_version:"+device.getCapability("advertised_browser_version"));
            stringOutValue = device.getCapability("device_os_version");
