Java applet - how to do this?

Question

I am translating a Midlet project to JApplet project. Microedition, UDPDatagramConnection, not available and lots more. How can tune this for JavaSE?
// code..........
package sip;
import javax.swing.JApplet;
import javax.microedition.io.*;
//import javax.microedition.midlet.*;
//import javax.microedition.lcdui.*;
import java.io.*;
import net.*;
import iax.audio.*;
//import iax.audio.gsm.*;
//import rtp.*;
public class InviteMIDlet extends JApplet implements CommandListener, SIPProviderListener {
// Vaiables to assign
private Display display;
public Form form;
private TextField To;
private Command sendCmd;
private Command exitCmd;
private Command hangupCmd;
public int sdpPort = 0;
private UDPDatagramConnection rtpCon = null;
private boolean incall = false;
// Sip Digest parameters
private String UserName = "";
private String passwd = "123";
private String SipServerIP = "212.";
private int SipServerPort = 5060;
// Sip parameters
private SIPProvider provider;
private String MediaIP = null;
private int MediaPort = 0;
// Thread assign
private UDPSend udpSend;
private UDPReceive udpReceive;
private AudioCapture audioCapture;
private AudioPlayer audioPlayer;
// End of Thread assign
// Main midlet parameters
public InviteMIDlet() {
form = new Form("SIP Dialer");
try {
display = Display.getDisplay(this);
To = new TextField("To:", "0012127773456", 40, TextField.LAYOUT_LEFT);
form.append(To);
sendCmd = new Command("Call", Command.ITEM, 1);
form.addCommand(sendCmd);
hangupCmd = new Command("Hangup", Command.ITEM, 2);
form.addCommand(hangupCmd);
exitCmd = new Command("Exit", Command.EXIT, 3);
form.addCommand(exitCmd);
form.setCommandListener(this);
rtpCon = (*UDPDatagramConnection*) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();
provider = new SIPProvider(UserName,passwd,SipServerIP, SipServerPort, 1225);
provider.start();
provider.addSIPProviderListener(this);
} catch (Exception ex1) {
ex1.printStackTrace();
}

UDPDatagramConnection is available under MIDP/Midlet. But after migration to j2se, it shows microedition does not exist. What is that mean?.. None of the J2ME (or JME - I forget what they're calling it this instant) classes are available in J2SE ((J)Applets, (J)Frames etc.).
Usually there is a J2SE equivalent. The JavaDocs for J2SE are available for download, or for web browsing at [http://java.sun.com/javase/6/docs/api/index.html]. I say usually since I can find no letter for letter equivalent of UDPDatagramConnection in the J2SE. There are a variety of classes that mention Datagram. Perhaps if you start there, you will figure how to do what J2ME does.
..i want to switch the same code, concept, in to j2se.
rtpCon = (UDPDatagramConnection) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();BTW - the advice to use code tags still stands. Most people will not so much as glance at code that is not formatted. After all, which is easier to read, this..
rtpCon = (UDPDatagramConnection) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();
..or this?
rtpCon = (UDPDatagramConnection) Connector.open("datagram://:");
sdpPort = rtpCon.getLocalPort();
