Midlet migration to JavaSe

[shamun]

Hello,

How to convert a midlet available microedition/UDPDatagramConnection for applet module? I get error that package does not exist, For example:


import javax.swing.JApplet;
import javax.microedition.io.*;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

import java.io.*;
import net.*;

public class InviteMIDlet extends JApplet {

private Display display;
public Form form;
private TextField To;
private Command sendCmd;
private Command exitCmd;
private Command hangupCmd;

private UDPDatagramConnection rtpCon = null;

....

}

I get error that package does not exist

When getting errors, please post the full text of the error.

You don't say what package is missing.

If a package is dose not means that you've not added relevant additional packages into your classpath, did you?

Best way to find a solution for your question is, as Norm says, post your complete error message to the forum. It's helpful to others who are looking into your question.

Please check the screen shot, it works in my Midlet project, But i am trying to move same concept to J2SE (applet based).

1. J2SE have microedition?
2. UDPDatagramConnection in J2SE is different?

Thank you

Did you added that package into your classpath?

Mannually i didnt add anything, Which libraries i should add?

@Eanga, others:

1. Which package i should add for my classpth?
2. I compile, this are the error: Bash | init: deps-clean: Updating p - Anonymous - TBvGthkY - Pastebin.com

package javax.microedition.media does not exist

Do you have a jar file with the above package in it?

1. Midlet working project i compiled and made a siptest.jar file in my path /home/sun/Download/siptest.jar
2. J2SE > same code > properties > libraries added as siptest.jar

Still i have same.

[Norm]

I'm not sure what your response said.
Do you have a jar file with the the javax.microedition.media classes in it? I imagine that you would have to download it from the SUN site.

What is in the siptest.jar file?

@Norm, @Eranga, others: I am translating following terms, i think i am getting fail because system is different:

J2ME: does support
===========
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.Form;

import javax.microedition.media.*;
import javax.microedition.media.Manager;
import javax.microedition.media.control.*;

import javax.microedition.io.*;
import javax.microedition.midlet.*;


J2SE:
=====
dont support them, none of those??????? How can i translate them, j2ME to >> j2SE!!!!!, I need atleast those alternatives.

1. Network
- socket = (UDPDatagramConnection) Connector.open("datagram://:" + localPort);
- Datagram send = socket.newDatagram(result, result.length, destAddr);
- Datagram receive = socket.newDatagram(socket.getMaximumLength());

2. Audio capture
- RecordControl rc;
- p = Manager.createPlayer("capture://audio");

3. Audio player
- pnew = Manager.createPlayer(recordedInputStream, "audio/X-wav");
- public class AudioPlayer extends Thread implements PlayerListener {
- Player pnew = null;

Here's all I can think of:
To recode the program to use J2Se vs the ME
remove all the import javax.microedition.... statements,
compile the program, get the list of errors and then go into the J2SE API doc and find if there is a class that could work and add an import statement for the package it's in.

No idea if the classes are compatible or if they'll need lots of recoding.

Good luck.

Agreed. That is the easiest way to solve this, if you don't know the alternatives. Each technology has different approaches as well.

Once you compile the code, as Norm says, you'll end up with list of errors. Try to solve those.

You already know that which package/library you want to use additionally. Are you using any IDE for coding in Java. Because most of the IDEs nowadays have an option to added external libraries to the project.
