Problem

How to get a List of all Access Points in J2me ?

Solution

Use IAPInfo API 1.0, available on devices with Java Runtime 1.4 to access Internet Access point information from the native database.

Sample Code

Imports

import com.nokia.mid.iapinfo.*;

List all available APNs

public getAPNList() throws IAPInfoException
{        
     //Obtain IAPInfo object by factory
     IAPInfo iapinfo = IAPInfo.getIAPInfo();
     //Get list of available Destination Networks
     DestinationNetwork dnetworks[] = iapinfo.getDestinationNetworks();
     //Get list of access points from each destination network
     for(int i=0;i<dnetworks.length;i++)
     {
	DestinationNetwork dn = dnetworks[i];
	AccessPoint aps[];
	// if Destination Network is not null, get list of APN in it.
	if(dn ! = null)
	{
		aps = dn.getAccessPoints();
		for(int j=0;i<aps.length;j++);
		{
		 AccessPoint ap=aps[j];
		 // if APN is not null, get its name
		 if(ap != null)System.out.println(ap.getName());
		}
	}
     }     
}

Note

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.
