Voice chat program

After a few days work, I have completed the mian voice chat program. I know there are so many people like me that wants that. I post these program. i will complete gui work later. and there is a problem in the program. if the speaking one do not speak for a while, the listening client will hear noise. Can some one help me.

Chat program in release 4.7c

hi guys,
I was wondering how one can create a chat program in abap. As its possible in Java & .Net why an abaper under estimate himself. Now here imagine a simple chat program where one can send some text from his SAP GUI which will appear on others SAP GUI and viceversa. Dont think about some messangers like yahoo or gtalk.(dont over estimate being an abaper)
So i developed two programs one to send text & other to receive text. Send prg. is module pool and receive prg. is a simple report which has timer class which gets data from table every second so user dont have to press any button to receive the message.
To start chat you have to run both programs in your GUI where from send program you enter your name in one text field and your message in other text field by pressing enter it gets update in table field(not every time it insert new record, it simply update previous so table size would not increase). As the person with whoem you are chatting is also running both programs, your message appears in 2nd program on his GUI & yours also. followed by your name.
Both chat programs works fine with more then two users also. i tried to combine both program in one screen so user can send & receive chat from one screen. but due to timer class used, its not possible as receive program keeps refreshing for every 1 second.
so i am wondering is thier any way to run one modulepool program & one report in a single screen. some thing like screen splitting or docking???
you are welcome to share your ideas regarding chat in ABAP/4(release 4.7)
Regards,
SUDHIR MANJAREKAR

Yes, thats right. There are few ABAP codes which you can find in the net and can improvise on that.
The program displays list of all users who are currently active on a list.
You can select user and select press button on the application tool bar to send a message.
Concerns here are: 1. The receiver cannot reply from the same popup. He has to run the program, select the user who has send message and reply. 2. You will not be able to see the entire message log.
For logging messages you can try creating standard text for tracking dialog between any two user and something of that sort.

GUI for chat program

Hi everyone,
I'm writing a simple chat program as a assignment at my Uni. I get stucked with the client GUI. I want to create a GUI like that of Yahoo messenger which has a list of connected users displayed on the GUI. When u double click on the name of the user, u will get connected to that user. I have no idea about creating a GUI list like this one. Can anybody help me with this? Thanks in advance!

There are many tutorials on this site; check the "tutorials" link on the column on the left.
Here are ones about GUIs:
http://developer.java.sun.com/developer/onlineTraining/GUI/
I'd suggest skipping over any tutorials prior to JDK 1.1 or even 1.2.
Read more recent ones. There have been significant improvements, especially w.r.t. event handling, between 1.0 and 1.1.

Need Help with Simple Chat Program

Hello Guys,
I'm fairly new to Java and I have a quick question regarding a simple chat program in java. My problem is that I have a simple chat program that runs from its own JFrame etc. Most of you are probably familiar with the code below, i got it from one of my java books. In any case, what I'm attempting to do is integrate this chat pane into a gui that i have created. I attempted to call an instace of the Client class from my gui program so that I can use the textfield and textarea contained in my app, but it will not allow me to do it. Would I need to integrate this code into the code for my Gui class. I have a simple program that contains chat and a game. The code for the Client is listed below.
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
public class Client
extends JPanel {
public static void main(String[] args) throws IOException {
String name = args[0];
String host = args[1];
int port = Integer.parseInt(args[2]);
final Socket s = new Socket(host, port);
final Client c = new Client(name, s);
JFrame f = new JFrame("Client : " + name);
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
c.shutDown();
System.exit(0);
f.setSize(300, 300);
f.setLocation(100, 100);
f.setContentPane(c);
f.setVisible(true);
private String mName;
private JTextArea mOutputArea;
private JTextField mInputField;
private PrintWriter mOut;
public Client(final String name, Socket s)
throws IOException {
mName = name;
createUI();
wireNetwork(s);
wireEvents();
public void shutDown() {
mOut.println("");
mOut.close();
protected void createUI() {
setLayout(new BorderLayout());
mOutputArea = new JTextArea();
mOutputArea.setLineWrap(true);
mOutputArea.setEditable(false);
add(new JScrollPane(mOutputArea), BorderLayout.CENTER);
mInputField = new JTextField(20);
JPanel controls = new JPanel();
controls.add(mInputField);
add(controls, BorderLayout.SOUTH);
mInputField.requestFocus();
protected void wireNetwork(Socket s) throws IOException {
mOut = new PrintWriter(s.getOutputStream(), true);
final String eol = System.getProperty("line.separator");
new Listener(s.getInputStream()) {
public void processLine(String line) {
mOutputArea.append(line + eol);
mOutputArea.setCaretPosition(
mOutputArea.getDocument().getLength());
protected void wireEvents() {
mInputField.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
String line = mInputField.getText();
if (line.length() == 0) return;
mOut.println(mName + " : " + line);
mInputField.setText("");

Thanks for ur help!i have moved BufferedReader outside the loop. I dont think i am getting exception as i can c the output once.What i am trying to do is repeat the process which i m getting once.What my method does is first one sends the packet to multicasting group (UDP) and other method receives the packets and prints.

Firewall burrowing/chat program help

I'm trying to develop a person-server-person chat program with java with the ability to burrow through firewalls. I'm using the example program from 1996 at: http://developer.java.sun.com/developer/technicalArticles/InnerWorkings/Burrowing/ as a guide.
I can get the applet up and running, but it won't connect to the server. The server says "Ready...", but neither connects to each other. They are both supposedly using port 6006.
When looking through the code of SimpleChatServer.java, I can't find where it designates an IP address, and can't figure out just how the applet is supposed to connect to the server.
Thanks everyone,
Mark

(Most if this code is from the example in the URL I first gave)
Here's the important code (trying 8080 this time):
Server:
int port = 8080;
     // Get the port number
     if (argv.length == 1)
     port = Integer.parseInt(argv[0]);
     // Create a server socket on the given port
     ServerSocket ss = null;
     try {
     ss = new ServerSocket(port);
     } catch (IOException e) {
     System.out.println("Could not listen on port: " +
port + ", " + e);
     System.exit(1);
     // Allocate a vector for all open connections to clients.
     Vector connections = new Vector();
     System.out.println("port: "+port+"Serversocket: "+ss);
     System.out.println("Ready...");
Output from DOS prompt is:
port: 8080Serversocket: ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8080]
Ready...
From the Client/Applet side, run from IE 5:
String str = getParameter("port");
     int port = (str != null) ? Integer.parseInt(str) : 8080;
     connection = new ServerConnection(getCodeBase().getHost(),port);
System.out.println("connection: "+connection);
Output from java console:
connection: ServerConnection@de9ac4
Error getting a new connection to read from
I have no idea what ServerConnection@de9ac4 means (I know where it came from, just not what it means).
Thanks,
Mark

Multicast chat program

Hi,
The problem I am having is when checking to see if two specific users are using the chat program as I want them to have a separate multicast session. The if statements work and the client sends the message. The server just doesn't seem to relay it back to the client in either case.
The code for the client part is below:
if (userName.startsWith ("Steve") || userName.startsWith ("David"))
MulticastSocket socket = new MulticastSocket (4447);
InetAddress address = InetAddress.getByName ("233.0.0.13");
          socket.joinGroup (address);
else
MulticastSocket socket = new MulticastSocket (4449);
InetAddress address = InetAddress.getByName ("232.0.0.13");
          socket.joinGroup (address);
And the server part:
if (received.startsWith ("Steve") || received.startsWith ("David"))
InetAddress group = InetAddress.getByName ("233.0.0.13");
packet = new DatagramPacket (buf, buf.length, group, 4447);
socket.send (packet);
else
InetAddress group = InetAddress.getByName ("232.0.0.13");
packet = new DatagramPacket (buf, buf.length, group, 4449);
socket.send (packet);
Does anyone have any ideas??

Cam chat programs and heat (MBP 17)

I have posted on this several times on the MBP board but no one seems to respond with any interest. I'll try a posting here.
My new MBP 17 is moderately warm as I use it for various typical things. But if I open either ISPQ (non-native) or SightSpeed (native) the aluminum case become a firery furnace. Ironic that they are chat programs because it's almost too uncomfortable to chat at any length since that involves constant typing.
When I close either of these programs the case cools down and Mr. Hyde becomes Dr. Jekyll again. I am using an outboard iSight firewire camera.
Am I taxing the graphic chip in a way that makes it hot even though the cpu activity during the "hot times' is never more than 25%? The DuoCore temp is never more than 72C and the fans don't come on.
Adium or iChat or Yahoo in the background have no such effect. But these two, specifically camchat software, create severe heat even if they are idle in the background.
thoughts? confirmation?

HI Eddie,
Does this Doc help http://docs.info.apple.com/article.html?artnum=30612 ?
Or this http://docs.info.apple.com/article.html?artnum=303848 ?
I must admit my MacBook Pro gets hot as well. I can't say if it gets more so if I am Chatting whether that is by Text or Video

At the very end of creating an email account the program asks for a software security device password, I have no idea what this is or where to find it.

What is the best Videoing Chatting program to use for my Macbook Pro?

I have had Skype for a while now and recently I updated to Skype 5, and the call qaulity is absolutely miserable, it keeps being blurry and freezing and it's a pain to try and talk through. So I was wondering is there any changes or fixes I can do to possibly make it better or improve the quality of my calls? If not is there any other good video chatting programs with good call qualities for Mac?
Im using Skype on my macbook pro, just saying.

How can you check if your wifi is good enough for a quality video call?
Yes I would post on Skypes forum, but there people their are not very helpful or supportive, so Im trying to get other people's opnions on ways to improve the call quality or find a better program.
Does anyone use any other video calling program that is just as good if not better? If so could you please mention it. I've looked on Google and I know some of the softwares or programs out there, but Id like to get peoples first hand experience with the programs and what they think of some of them out there.

How to create a job thru ABAP program for calling a program with variant???

Hello experts,
can u give me step wise procedure to create jobs for a program with a variant name thru ABAP???
Also, can a transaction can be scheduled as a job to run in background with a variant name???
Edited by: SAP USER on Jul 22, 2008 6:08 AM

Hi,
To create a job through ABAP program you can do the following.
Go to Menu bar.
In there, go to SYTSTEM> SERVICES> JOBS--> DEFINE JOB.
Then give the JOB NAME and CLASS in the screen that comes up.
This is how we schedule a program.
Now, to create a variant for a program -
First activate your program in SE38. Then execute it .
Now, click on SAVE button. It will open up the variant creation screen. Give the details there like variant name and value for the fields. Save and come back.
Hope this helps.
Regards,
Hari Kiran
