Sending To All Vs Sending To One Person In Server / Client Program
Apr 17, 2014I have two programs that I'll post below, one is a Server and the other is a Client. The ChatServer runs once and many clients can run ChatClient from separate computers and talk together in their GUI's. The the client program comes with two buttons, one that's simulates the sending of a message to a single user ; "Send Message To User", and one that just generally sends a message ; "Send Message To All". Although now the Clients on the server seem to be able to selectively send messages to an individual by giving the recipient name, all the clients can see that message, which is not exact what I am aiming for. What I am going for is having the "Send Message To User" button click to send a message to the named user without all other users seeing the message.
The Server Program Code
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
[Code] ....
Now I have tried thing like having various input output streams and trying to connect those, but no luck. Tried fiddling with having the names arraylist directing the messages to one client versus all but that did not work out either. How I what I would need to do to go about doing this?
Reading COM Port On GPRS Modem
Jul 16, 2014I'm a new in java program. I need reading COM port on GPRS Modem. I plug the GPRS Modem in my PC and it has connected. I use Eclipse and create a project and new a file a.java, i collect this following code from the internet and paste it into the a.java file.
Java Code:
package serial;
import java.io.*;
import java.util.*;
import javax.comm.*; //for accessing serialport
public class OwnPort {

You can see the result here
I don't know the result why return " Set default port to COM4. port COM4 not found."
I/O / Streams :: Read Calling Number From Modem?
Jun 6, 2014I am creating an application with having a callerID module. This module is to read calling phone number from modem. I have googled and reference many SerialPort related stuff but could not find a concrete solution. I am able to detect phone ring using serialEvent with javax.comm jar.
I am wondering if AT commands can be used to read/get calling phone number. I also referred following AT commands:
AT+CLIP
AT+VCID
AT+CNUM
1. Is it possible to read calling phone number using AT commands or any other alternative
2. Which AT command can be used and how to send from java application..
Run Cmd Commands Through Java?
Sep 17, 2014I would like my application to execute a command in cmd. The command looks like

Unix Commands From Windows
Feb 13, 2014I'm using windows.. and our server is UNIX.. I knew that it's possible to create DOS commands in java programs, I have tried it already..
What I want to know is, is it possible to create a java program (from windows) that can execute UNIX command?
Something like: I have a java program in my windows, and it will create a directory in UNIX server /home/dir..
Based on my research, I can connect to our server in command prompt of my windows using ftp <domain> but the commands there is limited.

Website Send Commands Application
May 8, 2014I have a Java application this application sits on a Dedicated server and gets information about the machine and run commands on the machine.
I need it so that i can run these commands from pressing buttons on a website. For example i press a button to retrieve CPU info, it goes to the app, and the app sends the CPU info back.
I'm fine with the website and app its just the middle bit. How do i get the app to run commands sent from a webpage. Been ratting my brains for a couple weeks now.

Program Can Accept Multiple Filter And Sort Commands At One Time
Mar 9, 2014What I'm supposed to be doing is making it so the program can accept multiple filter and sort commands at one time, and each should be separated by a whitespace.I was thinking about parsing the input again, using whitespace as the delimiter, then normally progressing with each token, as though there was only one command.
However, coding this the way I'm doing it will firstly probably take hours, and secondly, it's likely not even right. I don't have any real way to determine which token contains which data from the Song objects.These are the specific requirements for this portion:A sort/filter command consists of one or more of the following options:
-year:<year(s)>
-rank:<rank(s)>
-artist:<artist>
-title:<title>
-sortBy:<field>
Any number of these options may be given, and they may be given in any order. If multiple options are specified, they will be separated by whitespace.

View Replies View RelatedSending XML To PHP Service Via POST
Jul 7, 2014I have a server with a handful of php services. I communicate with these services by creating connections from java code. The services currently respond with XML, but that can be changed if an alternative way can improve performance.
One of the things I need to do is send varying sized payload (some large) to one of the services. My current plan is to create an xml file in java and perform a POST request with the XML as the payload. I am using an XML because the data is very structured.
From a performance point of view, would it be better to send the XML as a file or just as text? Also, is there a better way to send this data? These services will eventually be used by an android app, where performance and minimizing the size of the data packages will be extremely important.
Sending Two Strings Into A Constructor
Jun 13, 2014I did this using ArrayList<String> and my tests worked. Meaning I was able to read the strings in a different class through my constructor. However I want to use a string array because it will be easier to handle when I finish the program. I will send each players poker hand in and figure out who is the winner instead of putting it all onto a ArrayList and having to iterate through it. However whenever I did my check I am just printing null.
PokerFile class
void separateHands(String cards) {
//ArrayList<String>playerOne = new ArrayList<String>();
//ArrayList<String>playerTwo = new ArrayList<String>();
String[] playerOne = new String[10];
String[] playerTwo = new String[10];
[Code] .....
ignore the boolean methods I was just building the structure of the program. The print file is what is outputting this:
null
null
null
null
null
null
public class WinningHand extends PokerFile {
//ArrayList<String> p1 = new ArrayList<String>();
//ArrayList<String> p2 = new ArrayList<String>();
String[] p1 = new String[6];
String[] p2 = new String[6];
WinningHand(String[] p1,String[] p2)

Sending A File To Web Page

Sending Byte Arrays Over TCP / IP?
Sep 15, 2014I need to send a byte array across a network. I know how to do this. (server->client)
byte[] myArray = new byte[]{0,1,2,3,4,5,6,7,8,9};
DataOutputStream.write(myArray);
... and I know how to receive it.
byte[] myArray = new byte[10];
DataInputStream.read(myArray);
When I send over one of these arrays, it ends up stopping storing values in the array when only about half the array is received, even though the array is sent from the server all at once. This results in the receiver's array, in this case, being something like {1,2,3,4,0,0,0,0,0,0}.
I can easily solve this - and already have - by simply adding a loop onto it and waiting for the bytes to all be received, as the method returns the amount of bytes actually read.
byte[] myArray = new byte[10];
int bytesRead = 0;
while( bytesRead < myArray.length) {
bytesRead += DataInputStream.read( myArray, bytesRead, myArray.length - bytesRead );
}
I am simply wondering if there is a better solution to this, as the current solution isn't that elegant. Did I do something wrong to cause only a part of the array to be sent first? Would it be better to use DataInputStream.readByte() to read off the bytes one by one rather than an array at once, and then store them in an array afterward? Would this cause a performance decrease as each byte is read individually? (I'm sending an array of several million bytes)

View Replies View RelatedSynchronize UDP Sending And Receiving
Apr 16, 2015Say I was to make a computer game, the first person to play the game would have a joinable game and would then be the server, and anyone joining in would be the client and the server was updated with JSON data of the clients computer game, and the server would then update each client of each characters new data using JSON, I would need fast multi threaded connection handling with minimum overhead, Is there a specific way to do this? or are there many?
I have realized there are a few ways to send and receive data using UDP and while experimenting I have also found its quite hard to synchronise.
Do I have a connection listening until there is data to be sent and then switched back to listening?
Do I have the server listening for a microsecond and then checking to see of there's anything to send for a microsecond continuously?
Do I have multiple connections for sending and receiving
Do I create new connections for each new and individual packets to be sent and received dynamically on a thread?
What is the optimum most effective way and do my examples reflect much understanding at all? my resent attempts create new problems and rather than re invent the wheel I would like to know what is normally done.
Sending Values For GUI Fields
Jul 9, 2014I have a simple class, called InputManager, which has methods that communicate with another class DatabaseManager which has access to Database which is actually object that contains information about actual database.
My JFrame has Navigation class (extends JPanel). There I put all needed JButtons, JLists and so on.. This class has instance of InputManager and when user interacts with GUI components inside of it, Navigation calls InputManager methods, it then analyses the call and calls needed methods on DeviceManager, which then sends queries to Database and etc.
The problem is, that at the beginning (when user runs a program), I want to get information (which is actually values for my GUI components ) from Database. It could, for example, create another DatabaseManager and connect to the Database to get information, but it is okay to have two objects?
I was also thinking about sending same DatabaseManager object through InputManager to Navigation, but it seems strange for me to have two objects, which can interact with each other in both directions(Class A has instance of Class B, and Class B has instance of Class A). Is there anything bad this can do?
Also what I noticed that it seems odd that GUI class would have to get information from database. (Logic in GUI class).
Sending XML Records To Sax Parser Using Buffer
Mar 26, 2014i am having a below piece of code in my worker thread. In my output i am getting xml records from the database. I'm sending this output to a input stream & finally to a sax parser.My query is, before sending to the parser i need to store the input stream in buffer. The buffer should store 1000 records. For every 1000 records the parser should be called from buffer.
while (orset.next()) {
output = orset.getString("xmlrecord");
writeCount++;
InputStream in = new ByteArrayInputStream(output.getBytes("UTF-8"));
InputStream inputStream = new ByteArrayInputStream(output.getBytes("UTF-8"));

Sending Message From One Client To Another Via Server?
Apr 2, 2014I've just recently started playing around with network programming in Java, and I've come up with a simplistic server than can handle multiple clients and return the IP and port each one is connected to (or I'm under the impression that is so). What I've been requested to do as an exercise by one of the programming teachers at my high school (I'm not in a class, this is my own time) is send a message from one client to the other through the ServerSocket so that it may "watch" everything going on. I'm not sure how to go about this at all.
EDIT : now it never seems to go the the else or else if statements...
That is now the main problem. It never, ever, goes past the first if statement, no matter what it is.
EDIT : Okay, I haven't changed a line of code but suddenly not a single if statement is working. They just stopped. The client simply hangs and I can't type anything.
Server
public class Server implements Runnable {
Socket clientSocket;
Server(Socket clientSocket) {
this.clientSocket = clientSocket;
}
public static void main(String args[]) throws Exception {
ServerSocket ssock = new ServerSocket(3480);
