Need help coding simple chat client/server

I'm writing a simple chat server/client... its works fine when run on console.. but when i used Frames, AWT gui's.... it seems that the thread that is used to read the incoming message is suspended ... until i press the [send] button.. It seems to me that AWT consumes the time listening to any event.... and my thread is waiting... for the some AWT specific events to occur.....
If your interested guys.. i'm willing to post the source code.. here.

Try using the swing components. I think they are supposed to be more thread safe than awt. There is a tutorial for dealing with threads and swing:

hopes this helps

Need help regarding Simple Data Client and Simple Data Server VIs

Hi everyone.
I have a simple objective. I just want to test the 2 example VIs, "Simple Data Client" and "Simple Data Server" between 2 computers. I just want to check whether is this working between the 2 computers.
What I have done for now is that I changed the "address", from "localhost" in the "Simple Data Client.vi" to the IP address of the computer running the "Simple Data Server". I runned the "Simple Data Server" VI in one of the computers first followed by the "Simple Data Client" in the other computer. Nothing is received and the client just timed out.
Can anyone please help me troubleshoot and tell me what are the possible problems for this? Are there any wires connections between 2 computers that I am missing or any other configurations I have to make before I can successfully do this?
Thanks.
Regards,
Jonathan

Hi Lee.P.
I understand that. I was just feeling frustrated about the project not working. Sincere apologies from me.
I was wrong about the error number. It is not Error 60. It is Error 59 - The network is down, unreachable, or has been reset.. Yes, I have tried changing the port numbers at the 2 computers when trying to send/receive.
Could anything else be the problem?

Jonathan

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.

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.

Simple Chat Client using Java

Hi again. I'm thring to implement a simple chat client into my game and I need some help coding it, because it's way over my head. lol thanks

Well, you have left your question very vague, and people tend to get irritated by it. First of all, you need to really specify what you need. If you have nothing and need everything....you need to start by thinking about what methods will be used to send the messages...the GUI should be the last part. Do you need a server, plan on using a public server, or in a LAN environment. If you need a server, what type? Do you plan on writing your own?
For example, if you wanted to use an IRC server as your server, you could use PircBot as your backend for the communication and then integrate that into a GUI. If you wanted AOL, there are packages out there you can use.
If you have things thought out, you need to tell us what you are really asking and what you aready have. Otherwise, you have a lot of things to think about.

Help with installing a CHAT CLIENT/SERVER

i cant seem to get my chatclient or chatserver to successfully connect to my server. even if i do a local host 127.0.0.1 thing it STILL says that it cannot connect.
the server is a stand alone.
is there a general place to install the compiled files?
im SO frustrated right now.
im writing a card game. it is done but now i need to implement the networking. so im starting with a simple chat server and i cant even get THAT to work.
HELP.....

I'm actually working on a card game (client/server if I can) as well, when I spotted this message. Card games work for me because they're simple, they're relatively fun and easy to figure out, and they aren't real-time or heavy on animation/sprites/hardware acceleration.
http://vpoker.sourceforge.net/ is a java based card game that has some excellent examples of how to conceptualize a 'card' object and a 'deck' of cards.
good luck, can try emailing me if you want to toss around ideas about our respective card games.

Need help with simple file sharing application

I have an assignment to build a Java File Sharing application. Since I'm relatively new to programming, this is not gonna be an easy task for me.
Therefore I was wondering if there are people willing to help me in the next few days. I will ask questions in this thread, there will be loads of them.
I already have something done but I'm not nearly halfway finished.
Is there a code example of a simple file sharing application somewhere? I didn't manage to find it.
More-less, this is what it needs to contain:
-client/server communication (almost over)
-file sending (upload, download)
-file search function (almost over)
-GUI of an application.
GUI is something I will do at the end, hopefully.
I hope someone will help me. Cheers
One more thing, I'm not asking for anyone to do my homework. I will only be needing some help in the various steps of building an application.
As I said code examples are most welcome.
This is what I have done so far

                System.out.println("Error!");
}Those three classes are simple client server multi-threaded connection.

Now the other part that contains the search function looks like this:
package ToJeTo;
import java.io.*;
import java.util.*;
public class User {
    String nickname;
    String ipAddress;
    static ArrayList<String> listOfFiles = new ArrayList<String>();
    File sharedFolder;
    String fileLocation;
    public User(String nickname, String ipAddress, String fileLocation) {
        this.nickname = nickname.toLowerCase();
        this.ipAddress = ipAddress;
        sharedFolder = new File(fileLocation);
        File[] files = sharedFolder.listFiles();
        for (int i = 0; i < files.length; i++) {
            listOfFiles.add(i, files.toString().substring(fileLocation.length()+1));
public static void showTheList() {
for (int i = 0; i < listOfFiles.size(); i++) {
System.out.println(listOfFiles.get(i).toString());
@Override
public String toString() {
return nickname + " " + ipAddress;
User Manager:
package ToJeTo;
import java.io.*;
import java.util.*;
class UserManager {
    static ArrayList<User> allTheUsers = new ArrayList<User>();;
    public static void addUser(User newUser) {
        allTheUsers.add(newUser);
    public static void showAndStoreTheListOfUsers() throws FileNotFoundException, IOException {
        BufferedWriter out = new BufferedWriter(new FileWriter("List Of Users.txt"));
        for (int i = 0; i < allTheUsers.size(); i++) {
                System.out.println(allTheUsers.get(i));
                out.write(allTheUsers.get(i).toString());
                out.newLine();
        out.close();
}Request For File
package ToJeTo;
import java.util.*;
public class RequestForFile {
    static ArrayList<String> listOfUsersWithFile = new ArrayList<String>();
    Scanner input;
    String fileName;
    public RequestForFile() {
        System.out.println("Type the wanted filename here: ");
        input = new Scanner(System.in);
        fileName = input.nextLine();
        for (User u : UserManager.allTheUsers) {
            for (String str : User.listOfFiles) {
                if (str.equalsIgnoreCase(fileName))
                    listOfUsersWithFile.add(u.nickname);
    public RequestForFile(String fileName) {
        for (User u : UserManager.allTheUsers) {
            for (String str : User.listOfFiles) {
                if (str.equalsIgnoreCase(fileName))
                    listOfUsersWithFile.add(u.nickname);
    public static List<String> getAll() {
        for (int i = 0; i < listOfUsersWithFile.size(); i++) {
            //System.out.println("User that has the file: " + listOfUsersWithFile.get(i));
        return listOfUsersWithFile;
}Now this is the general idea.
The user logs in with his nickname and ip address. He defines his own shared folder and makes it available for other users that log on to server.
Now each user has their own list of files from a shared folder. It's an ArrayList.
User manager class is there to store another list, a list of users that are connected with server.
When the user is searching for a particular file, he is searching through all the users and their respective files lists. Therefore for each loop inside a for each loop.
Now the problem is how to connect all that with Client and Server class and put it into one piece.
GUI should look somewhat like this:

I think the easiest way to do it would be to cut an paste most of that code into your program. Then all you have to do is change some names so that it uses your textfield and textarea.

Can Simple Data Client/Server VIs communicate between computers?

I am having trouble using the Simple Data Client VI / Simple Data Server VI to communicate between computers? Can these VIs do this ..or do they simply communicate between each other on a single computer? TIA.

NO it can be used between two computers. You have to replace the localhist string with the IP address of the computer running the server and make sure that the server computer is allowing external connections on the specified port.

Need Help with simple array program!

Hi, I have just recently started how to use arrays[] in Java and I'm a bit confused and need help designing a program.
What this program does, it reads in a range of letters specified by the user. The user then enters the letters (a, b or c) and stores these characters into an array, which the array's length is equal to the input range the user would enter at the start of the program. The program is then meant to find how many times (a,b and c) appears in the array and the Index it first appears at, then prints these results.
Here is my Code for the program, hopefully this would make sense of what my program is suppose to do.
import B102.*;
class Letters
     static int GetSize()
          int size = 0;
          boolean err = true;
          while(err == true)
               Screen.out.println("How Many Letters would you like to read in?");
               size = Keybd.in.readInt();
               err = Keybd.in.fail();

}     Some errors i get with my program are:
When reading in the letters to store into the array, I get the last letter I entered placed into the entire array. Also I believe my code to find the Index is incorrect.
Example Testing: How many letters would you like to read? 3
Enter letter (a, b or c) (# to quit): a
Enter letter (a, b or c) (# to quit): b
Enter letter (a, b or c) (# to quit): c
It prints "There are no a's'" (there should be 1 a at index 0)
"There are no b's" (there should be 1 b at index 1)
and "There are 3 c's, first appearing at index 0" ( there should be 1 c at index 2)
The last thing is that my code for when the user enters "#" that the input of letters would stop and the program would then continue over to the counting and searching part for the letters, my I believe is correct but I get the same problem as stated above where the program takes the character "#" and stores it into the entire array.
Example Testing:How many letters would you like to read? 3
Enter letter (a, b or c) (# to quit): a
Enter letter (a, b or c) (# to quit): #
It prints "There are no a's'" (should have been 1 a at index 0)
"There are no b's"
and "There are no c's"
Can someone please help me??? or does anyone have a program simular to this they have done and would'nt mind showing me how it works?
Thanks

Without thinking too much...something like this
for(int start = 0; start < size; start++) {
            System.out.println("Please enter a letter (a, b or c) ("+size+" max), enter # to stop:");
            input = Keybd.in.readChar();
            while((input != 'a') && (input != 'b') && (input != 'c') && (input != '#')) {
                Screen.out.println("Invalid Input");
                System.out.println("Please enter a letter (a, b or c) ("+size+" max, enter # to stop:");
                input = Keybd.in.readChar();
            if(input == '#') {
                    break;
            letter[start] = input;
        }you dont even need to do start = size; coz with the break you go out of the for loop.

Need Help With Simple ABAP Code

Hello,
I'm loading data from a DSO (ZDTBMAJ) to an Infocube (ZCBRAD06). I need help with ABAP code to some of the logic in Start Routine. DSO has 2 fields: ZOCTDLINX & ZOCBRDMAJ.
1. Need to populate ZOCPRODCD & ZOCREFNUM fields in Infocube:
    Logic:-
    Lookup /BI0/PMATERIAL, if /BIC/ZOCBRDMAJ = /BIC/OIZOCBRDMAJ
    then /BIC/ZOCPRODCD = ZOCPRODCD in Infocube
           /BIC/ZOCREFNUM = ZOCREFNUM in Infocube
2. Need to populate 0G_CWWTER field in Infocube:
    Logic:
    Lookup /BIC/PZOCTDLINX, if /BIC/ZOCTDLINX = BIC/OIZOCTDLINX
    then G_CWWTER = 0G_CWWTER in Infocube.
I would need to read single row at a time.
Thanks!

I resolved it.
