Hello,
I am getting following error while running the cloud test application for Java. I am a member and downloaded the key to run the servlet.

Can you verify that you can ping 'api.wurflcloud.com' from your server?

it seems to us that this is a problem with the network connection.

thanks

Error is coming from WURFL API. Yes, Servlet is unable to connect with "api.wurflcloud.com". Do I need anything from my dev env. I am unable to ping "api.wurflcloud.com" also I am unable to reach this URL from browser. What kind of call API is makingto "api.wurflcloud.com".


AbstractDevice device = manager.getDeviceFromRequest(req, resp, capabilities);


Here is the example Java code that WURFL generated
public class MyCloudClientServlet extends HttpServlet {
private final Logger logger = LoggerFactory.getLogger(getClass().getName());
private ICloudClientManager manager;
//customize with your cloud service key
private static final String TEST_API_KEY = "708005:kItTWDPl42XsfFBco0vG3Rdiy17NeaUK";
private String[] capabilities;

/**
* Create shared ICloudClientManager instance by mean of CloudClientLoader
*
* @throws ServletException
*/
public void init() throws ServletException {
System.out.println("INSIDE WURFL CLOUD INIT ");

super.init();
try {
CloudClientLoader loader = new CloudClientLoader(TEST_API_KEY);
manager = loader.getClientManager();
capabilities = loader.getSearchedCapabilities();
} catch (Throwable t) {
throw new ServletException(t);
}
}

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("INSIDE WURFL CLOUD DoGet ");

doPost(req, resp);
}

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("INSIDE WURFL CLOUD DoPost ");


String useragent = req.getHeader("User-Agent");
if (useragent == null) useragent = req.getHeader("user-agent");
if (logger.isDebugEnabled()) logger.debug("user agent: " + useragent);
long start = System.currentTimeMillis();
AbstractDevice device = manager.getDeviceFromRequest(req, resp, capabilities);
long time = System.currentTimeMillis() - start;
logger.info("device: " + device);
Info i = new Info(time);
String apiVersion = manager.getAPIVersion();
if (logger.isDebugEnabled()) logger.debug("apiVersion: " + apiVersion);
i.setCloudVersion(apiVersion);
i.setClientVersion(manager.getClientVersion());
req.setAttribute("device", device);
req.setAttribute("info", i);
RequestDispatcher rd = req.getRequestDispatcher("/WEB-INF/response.jsp");
rd.forward(req, resp);
}

Certainly there is a network issue if you are unable to ping api.wurflcloud.com. The client makes requests to that host via HTTP (port 80), although if you visit it with your browser, it will respond with something like "Not found". You must have one of these two problems:

1. DNS is not working. You can test this from a command line on Windows/Linux/Mac with "nslookup api.wurflcloud.com". You should see a response like "uk.wurflcloud.com" and an IP address. The result may vary based on your location, so it might be a different hostname, but it should not fail.

2. You have no route to the outside internet. Perhaps you have a firewall on your computer or network that is blocking outbound traffic, or maybe you need a proxy to access the internet, but in either case, you are not able to contact our servers. If you can't ping 50.57.185.227 from your location, there is something like a proxy going on (that is one of our US WURFL Cloud servers - I gave you the IP to avoid the DNS problem above).

Your development environment should work just fine without any special configuration, assuming you have outbound internet access.

I can access outside internet from my computer, I am accessing your website and downloading examples etc and can also access any other website. I have set the proxy settings in Eclipse to http-proxy:80, but still I am getting connection timeout error in eclipse. I tried to deploy example war file on Weblogci server and run it, I am aslo getting connection error from WL server as well. Do I need to set anything in Eclipse or weblogic to make a connection to api.wurflcloud.com.

Hello,

We have a premium account with WURFL, and looking for some help to resolve this issue, please let us know why we cannot reach to api.wurflcloud.com.

We will get our Java engineer to contact you and work with you on the problem. Is the email address with which you have registered the right one to contact you?

Thanks

Have you confirmed that there is no web proxy in your environment? Most modern browsers will detect the presence of a proxy and use it for HTTP traffic, but java/weblogic will not.
