instead of this you can write//
url = url + ";deviceside=false";
httpConn = (HttpConnection) Connector.open(url);
Please add network extension in this line
httpConn = (HttpConnection) Connector.open(url);
at the end of the url please check did you add url extension
for suppose you are using wifi then you have to add
httpConn = (HttpConnection) Connector.open(url+";interface=wifi");
this is working for interface if you want to other types of networks then just refer my answer here

After referring tons of tutorials finally somehow I managed to develop java push client for Blackberry OS 7.0 (registering in RIM and server side are completely ok, this is the server script). Now the program running on the device and when new push massage revived there is a little arrow blinking on right up corner of the device, but I haven't that much knowledge to show that message in a label field or any other UI component. Please tell me how to show the revived push message in a screen. I'm beginner in programming so I haven't that much of knowledge need your help. Here I post all the codes that I have used.

What I have to add for the main screen to show in coming message ??
Thank you in advance.
I am new in BB trying to parse Json file and just want to print the Json responce in a Dialog. But it raises an error regarding No Application Instance and is also getting IllegalStateException. I use GET url method for it.
I Have also add permission in UiApplication like ..
UIApplicationScreen
public static void main(String[] args) {
ApplicationPermissions permRequest = ApplicationPermissionsManager.getInstance().getApplicationPermissions();
permRequest = new ApplicationPermissions();
permRequest.addPermission( ApplicationPermissions.PERMISSION_INTERNET );
ApplicationPermissionsManager.getInstance().invokePermissionsRequest( permRequest );
UiFunApplication app = new UiFunApplication();
app.enterEventDispatcher();

Hello dear you need to use url extension for blackberry
so please try to change this line
String aa=jsonresponse(url);
as
String aa=jsonresponse(url+";interface=wifi");
After successfully completed download data from url then once check String aa getting any value or not? if it get data then follow
try this if it is working fine then go through this following link
Guide for URL extensions
Enter Url in
String url="Your url";
String request=jsonresponse(url+";interface=wifi");
String response = parseJSONResponceInBB(request);
if(response .equalsIgnoreCase(""))
{
add(new LabelField("NO res"));
}
else
{
add(new LabelField(response ));
}
i am trying to get data sending GET request to a php service, but unfortunately i am not getting any result, i am using Blackberry Simulator 9800, here is my code,
HttpConnection conn = null;
InputStream in = null;
StringBuffer buff = new StringBuffer();
String result = "";
String url = "http://www.devbrats.com/testing/ActorRated/Service/cities.php";
try{
conn = (HttpConnection) Connector.open(url,Connector.READ_WRITE, true);
conn.setRequestMethod(HttpConnection.GET);
conn.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Confirguration/CLDC-1.0");
if(conn.getResponseCode() == HttpConnection.HTTP_OK){
in = conn.openInputStream();
//parser.parse(in, handler);
buff.append(IOUtilities.streamToBytes(in));
result = buff.toString();
}
else{
result = "Error in connection";
}
} catch(Exception ex){
ex.printStackTrace();
} finally{
try {
if(in != null){
in.close();
}
conn.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Please tell me what is the problem with it,
You will have to use this : http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/io/transport/ConnectionFactory.html
To properly create a network connection with the right parameter.
If you are not using OS5+ use this : http://www.versatilemonkey.com/HttpConnectionFactory.java
