Desperately need Java network programming help!!!
I need to make a Distributed File Sharing System (DFSS) using java language. The system should not make use of the central file server. The system should coordinate the concurrent access of files over the distributed environment. Caching may be used to enhance the system performance.
It is basically network programming.
Does any one have any idea how to make the DFSS. If you do please help!!!
thank you in advance for you help
cheerswell, you're getting somewhere I guess. My original answer was intentionally vague because your original question was so vague. These fora are no good for asking questions like "how do I implement a distributed file system", they are good for asking things like "the following line(s) of code generate the following condition I didn't expect, rather I expected this condition, could someone tell me what is going on?" or something of similar specificity.
So you are now asking how to, for instance, check to see if a text file is being shared. This is still too vague, but it's better than "how do I write a file sharing system". If you are feeling particularly industrious, go look at a project JXTA at http://www.jxta.org/ - it's open source, you can look at the code. Of course, if you're brand new, this might not help. In fact, not to discourage you, but if you're that new, this is not the project to be doing.
Good Luck

Advanced Java network programming
I have been playing around with the various Server/Client tutorials not only on this site but many others for some time now. Whilst I have learnt a great deal I am now trying to further my knowledge.
The problem is, there does not seem to be a great deal of information on the Web realting to the advanced network programming stuff. Obviously not having a network of my own I am now interested in learning various ideas using the Internet. Obviously not being a prat about it and port scanning other computers or anything like that.
I was hoping someone reading this might have a suggestion about where to go next in my learning curve. Also if anyone could recommend any good sources of info for this type of stuff.
I've currently got three telephone lines in, each line with a seperate Internet account set-up. What I want to do is have them all connected to the web at once and then attempt various things, such as connection, that type of stuff.
Help really appreciated.
Thanks,
kPMaybe I'm catching the wrong vibe here, but it seems to me that you need to learn a bit about networking in general, before you worry about how it's all done in java. I would suggest a good basic computer networking text book. After you have good understanding of how different networks works, packet structure of the various common protocols, IP, TCP over IP and UDP over IP. I think the java code to implement it all will just fall into place. my AIM SN is SpinozaQ if you would like a book suggestion. I don't have any names going through my head right now.

Simple network programming, question ...
Hello
I'm a beginning learning student from the Netherlands.
My clientcode looks like this:
import java.io.*;
import java.net.*;
import java.util.*;
public class ConsumerClient
private static InetAddress host;
private static final int PORT = 1234;
public static void main(String[] args)
try
host = InetAddress.getLocalHost();
catch(UnknownHostException uhEx)
System.out.println("\nHost ID not found!\n");
System.exit(1);
sendMessages();
private static void sendMessages()
Socket socket = null;
try
socket = new Socket(host, PORT);
Scanner networkInput = new Scanner(socket.getInputStream());
PrintWriter networkOutput = new PrintWriter(socket.getOutputStream(),true);
//Set up stream for keyboard entry...
Scanner userEntry = new Scanner(System.in);
String message, response;
do
System.out.print("Enter 1 for resource or 0 to quit: ");
message = userEntry.nextLine();
networkOutput.println(message);
if (message.equals("0") || message.equals("1"))
response = networkInput.nextLine();
System.out.println("\nSERVER> " + response);
else
System.out.println("*** Invalid! ***\n");
while (!message.equals("0"));
catch(IOException ioEx)
ioEx.printStackTrace();
finally
try
System.out.println("\nClosing connection...");
socket.close();
catch(IOException ioEx)
System.out.println("Unable to disconnect!");
System.exit(1);
I've also created a server.
When I start the client server program, the following error occurs at line:
response = networkInput.nextLine();
NoSuchElementException:
No line found (in java.util.Scanner)
does someone know how to solve this problem?
thanks in advance
greetings
BastiaanI think the socket you're connecting to ( server ) didn't send data to your socket. So that the method networkInput.nextLine(); returns null and the exception occured

Simple Java 3D programs CPU Usage spikes to up to 90 percent!
Hi, everyone. Im completely new to Java 3D and Im toying around with basic program structure right now. My code is based off of that in the first chapter on 3D in Killer Game Programming in Java. I removed most of the scene elements, replacing them with a simple grid, Maya style. (Yes, Im starting off small, but my ambitions are grand I intend on creating a polygonal modeling and animation toolset. After all, the Maya PLE is dead damn you, Autodesk! and I just plain dislike Blender.) I implement a simple OrbitBehavior as a means for the user to navigate the scene. That part was basically copy and paste from Andrew Davisons code. The mystery, then, is why the programs framerate drops below 1 FPS and its CPU Usage spikes to up to 90 percent, according to the Task Manager, when I tumble the scene. Id appreciate anyone taking the time to look at the code and trying to identify the problem area. (Ive undoubtedly missed something totally newbish. -.-) Thank you!
(Also, I had the worst possible time wrestling with the posting process. Is anyone else having trouble editing their posts before submitting them?)

How to run the simple java card program in eclipse?
I am trying to run a simple HelloWorld program in eclipse 3.5 having java card development kit 2.2 installed in it.
Firstly,I go to the JCWDE tab and press start..then when trying to deploy that package its giving me error like " com.hw.HelloWorld: unsupported class file format of version 50.0." can any one help me in this what is this error???n how to resolve n run this program..Hi,
It is because the converter works on byte code and it only supports a subset of the Java language (see the JC specifications). It is kind of like compiling you code on Java 6 and trying to run it on Java 5. The JCDK outlines the required compiler version.
Cheers,

Help needed for java network programming
How can I implement a GUI as a client in my server-client program.
I have a window(JFrame)having one Textfield and a "Send" button.
My requirement: While execution, the GUI should start as a client, and whatever textinput I will give to the Textfield, that should be printed in the server program.
So, how can I implement a GUI window as a client.
If any of U have idea,Please let me know soon.
Regards.Well, the client part and the GUI part are separate. The button simply calls a send method.
As for the networking, you can just use a Socket and a ServerSocket on the client and server, respectively. Then, wrap a PrintStream around one side and a BufferedReader(InputStreamReader()) around the other. You'll be able to talk back and forth once your connection is established; it's up to you to read from the BufferedReader and use the results on the server side. -

I am trying to make a Third-party chat client an alternative of rediffbol for rediffchat
* To do this, I downloaded a packet sniffer (Sniphere) and started monitoring the packets sent and received by the original Rediff messenger.*
* Rediff Bol uses the MSNP protocol to connect...*
*1. First the client establishes a tcp connection with the DISPATCH server "203.199.83.62 : 1863"*
*2. then the client sends the DISPATCH server its VERSION and a command so that the dispatch server can send back a list of available notification servers...*
*3. Then the DISPATCH server sends back the client a list of available NOTIFICATION servers......the client connects there and like this it goes on...*
I am using Java. I captured the packet 2. where the command the and the version is sent. I sent the exact packet to the server but due to some reason the dispatch server is not sending back the list of NOTIFICATION servers...
the client.java is attached
there is a difference of negotiation that is occuring between my prog-server and rediffmessenger-server
its like this
pck 1<client-outgoing>: 2<server-incoming> and 3<client-outgoing> which I think is a three way handshaking...its same with my program as the original rediffmessenger
pck 4: this in case of the rediffmessenger is the command and version<outgoing>...same in my case
pck5: this is supposed to be an incoming stream from server 203.199.83.62:1863 which will have the data of available notification servers......WHICH in my case is becoming an outgoing packet from my client<i didnt send anything except the command , refer to client.java> which contains nothing as DATA...and in the later packets the server never sends the list of notification servers...import java.net.*;
