Our black berry app works with the att 3g network in USA. Client in Europe, Japan and china, are trying to test the app using their 3G network. They are able to run the app using wifi. But not with 3G.



Now the case here is , in USA, we have load the BB app on BB-storm as well as BB-9000. and it works fine.

Clients in other countries are testing on BB-9700.I am not able to see any data coming into our servers when they use 3G network.



So can any one please lead us in the right direction? Why app doesn’t work with carriers in japan or china but works in USA?





Thanks in advance.

Do your clients have Blackberry data plans? If not, do they have the APN values set correctly for their location?

Sir,

Our clients do have the data plans of DOCMO(JAPAN) UNICOM(CHINA). They have their 3G n/w

here is the code i have written

private HttpResponse sendXmlOverHttp(String url, String xmlRequest, boolean loginRequest)
throws Exception {
HttpConnection httpConnection = null;
OutputStream os = null;
InputStream is = null;
System.out.println("REQ: " + xmlRequest);
try {
url = url + getConnectionString();
httpConnection = (HttpConnection) Connector.open(url);

if(loginRequest) {
cookie = null;
} else {
httpConnection.setRequestProperty(COOKIE, cookie);
}
httpConnection.setRequestMethod(HttpConnection.POS T);
os = httpConnection.openOutputStream();
os.write(xmlRequest.getBytes());
os.flush();

int responseCode = httpConnection.getResponseCode();

is = httpConnection.openInputStream();

// Get the length and process the data
int len = (int) httpConnection.getLength();
System.out.println("Length of response: " + len);
String xmlResult = null;
if (len > 0) {
int actual = 0;
int bytesread = 0;
byte[] data = new byte[len];

actual = is.read(data, bytesread, len - bytesread);
bytesread += actual;
}
xmlResult = new String(data);
}

xmlResult);

I see that you are appending "deviceside=true" without the carrier-specific APN values. This won't work on most networks.

I don't know that this is what is tripping you up, but it looks suspect to me.

[hrbuckley]

Well, kudos to Dougsg38p for trying, and he may be right. It looks to me like you are throwing every possable connection method specification at the problem, but it is difficult to follow the logic of such a large chunk of code that is not formatted. Perhaps you could read this sticky post and try again.
