How to make a network connection using a selected Access Point in J2me
How to make a network connection using a selected Access Point in Java ME?
Use IAPInfo API 1.0, available on devices with Java Runtime 1.4 to access Internet Access point information from the native database and use it with GCF, by appending the access point's ID to the URL before passing it to Java Generic Connection Framework.
Get APN id & make connection
public StreamConnection getConnection(String APN_Name, String url) throws Exception
//Obtain IAPInfo object by factory
IAPInfo iapinfo = IAPInfo.getIAPInfo();
AccessPoint ap = iapinfo.getAccessPoint(APN_Name);
//Make connection using selected access point, selected access point's ID is append to URL which is passed to GCF
StreamConnection sc = (StreamConnection)Connector.open(ap.getURL(url));
Check your target device spec's (http://www.developer.nokia.com/Devices/Device_specifications/?filter1=all) for support of IAPInfo API on it before using it.
