Problems with my client server program

I am programming a client to server messeging system. I have been getting this error. [i programed a JOptionPane window if an IO error ocured and every time i connect with the client in keeps popping up. Here is part of my code from the [b]server:
     class listener extends Thread {
          public void run() {
               try {
                    recever = new ServerSocket(port);
                    send = recever.accept();
                    Thread process = new Thread(new mt());
                    process.start();
               catch (IOException ioe) {
     class mt extends Thread {
          public void run() {
               try {
                    send.setSoTimeout(1);
               catch (IOException ioe) {
               while (true) {
                    try {
                         in = new BufferedReader(new InputStreamReader(send.getInputStream()));
                         data.add(in.readLine());
                         JOptionPane.showMessageDialog(null, data, "this was the data", JOptionPane.INFORMATION_MESSAGE);
                    catch (NullPointerException ioe) {
                    catch (IOException ioe) {
                         JOptionPane.showMessageDialog(null, "Error in the server!!", "ERROR", JOptionPane.WARNING_MESSAGE);
     public static void main(String args[]) {
          new server().setVisible(true);
}Now froim the client:
if (e.getSource() == go) {
               if (connected == true) {
                    try {
                         out = new PrintWriter(new OutputStreamWriter(connector.getOutputStream()));
                    catch (IOException ioe) {
                         JOptionPane.showMessageDialog(null, "Error sending", "ERROR", JOptionPane.WARNING_MESSAGE);
                    type.setText("");
               if (connected == false) {
                    JOptionPane.showMessageDialog(null, "You are nnot connected!!", "ERROR", JOptionPane.WARNING_MESSAGE);
If you need more code to understand my problem just ask.
Thanx

Don't you think it might be a good idea to find out what kind of IOException you're getting? At least display ioe.getMessage. showMessages will take an Object array instead of a single string so you can do:
JOptionPane.showMessageDialog(null, new Object[]{"Error in server", ioe.getMessage}, "Error",
JOptionPane.ERROR_MESSAGE);

Urgent :problem with JTable on server program

hi all i am writing an internet cafe timer.there is a table with the following colums:PC Name,IP Address,Status,Time Left, Time Login. ,on the server GUI. Whenever a client connects,a new row having the clients details is added to the table model, which reflects on the table.but if a client disconnects and reconnects, i want it to search thru the rows in the model, if there is a row with its information already,it shouls simply update the status column to "Reconnected", and not add an entirly new row, but if there is no row with its information, it can then add a new row with its information.
Simply put, when a client connects,it should check
1)if the table is empty, add a new row;
2)else, check if tabe already has a row for the client, then update the row,else add a new row.
its not working this way.it only works for the first client to connect,if other clients connect and disconnect,it still adds a new row, instaed of updating.
the method doTable() in class ClientThread is what i use .please check it out and help me.
i have a thread for each client.when a client connects, the server starts the thread and passes an instance of the server ui to the thread, so the threads acess the tablemodel thru this instance.
Here is a simple run down of my classes

In the UI is defined the InputMap/ActionMap pair to respond to keys. There is defined an action for ENTER. I have had the same problem, and the only thing that worked for me was to clear the actionMap, and reassign some keys to their original action, and some (e.g. ENTER, TAB) to my actions. This worked. With TAB is harder beacuse i guess it's deeper in the JVM implemented, but after a while i've managed to overwrite that too.

Client Server program using Applets for client

Creating a client server program using Applets for the clients.
Having problems distrubting the message from client to client
using ObjectOutputStreams/ObjectInputSteams.
I can connect each client to simple server and respond with by writting
the i/o stream of each client but unable to communicate from client to client. If any one out there has in tips of creating a class of objectOutputStreams that holds a array of ObjectOutputStreams and then broadcasts the message to every client, it would be much appreciated
Thanks.

Cheers poop for your reply
I never explained the problem properly. What it is I am trying to set up a Client Server program using Applets as the clients GUI. The problem is broadcasting the message to multiply client connnection(s).
Below is code, each client can connect and send message to the server. The problems is broadcasting the message to every client connection. The every client can input a message but only the last connected client can receive the message?????? Thanks in advance..

Design Pattern for multithreaded client server program

I asked this question in another post, but with other stuff, so I'll distill this one.
I am creating a multi-threaded client server program (just for learning - a chat program at this point). I built the server and client in swing, and I'm wondering what the best design pattern is for this setup. Right now all the swing stuff is in the MyServer class. In that class I have a loop accepting client connections to the serverSocket and creating a new MyServerThread (threaded client connection).
The problem is that all the work of creating input streams, interacting with the server, all that stuff is done in the MyServerThread class, but I want that text to be written up to the Swing objects - which is in the MyServer class. So right now in the MyServerThread class I pass the MyServer object into it, but I'm not sure if that is really the most robust thing to do. Does anybody have any suggestions as to how this should be done. If somebody has an article they'd like to point to I'll check it out too. But if it's just the run-of-the-mill multithreaded client-server article, I've read alot and most don't specifically address my question.

Thanks for the reply Kaj, and I think I'll keep my design for now, since it's just quick and dirty. I've read the MVC concept a while ago and I'll revisit it again when I get more serious. But I have a question, why should I be using a callback interface, why an interface at all? And then make MyServer implement that interface...why not just pass MyServer to the thread object? Or is there something down the line that I did not forsee?

About the communication issues in the client-server program

About the communication issues in the client-server program
Hi, I have some questions about the communication issues in a java project, which is basically the client and server architecture. In brief, the client, written in java, can be deployed anywhere, and in the following part, assume it is in the LAN (Local Area Network) which is connnected to the internet through the firewall and/or proxy, and the server, written in
java too, simply provides the listening service on a port in a remote machine. And assume the server is connected to the internet directly so that the scenario can be simple to focus on the core questions.
My questions are as follows:
1 About the relationship between the communication port and protocol
Generally, protocols at the application level like HTTP, FTP have their own default port, e.g., HTTP is corresponding to 80,
FTP is to 25. But it is NOT necessary for the web server to provide the HTTP listening service at port 80, right? E.g, Tomcat provides the HTTP listening service at 8080. So it means the default relationship between the application protocl and their port is some routine, which is not necessary to follow, right?
2 Assume a LAN connected to the internet through a proxy, which only allows HTTP protocol, then questions are:
2.1 Does the proxy recognize the HTTP request from the client by the port number (carried in the request string)? For example, when the server provides the HTTP listening service at 80, then the request from the client will include the port number 80, then the proxy will parse such info and decide if or not the request can be out.
2.2 Does the proxy recognize the HTTP request from the client by protocol (carried in the request string)? For example, the protocol used in the communicatin should be included in the request, then the proxy can parse it to make the decision.
3 In java programm, if using the HTTP protcol, then on the client: the corresponding API is java.net.URLConnection, right?
If using the TCP protocol directly, then on the client:the corresponding API is java.net.Socket, right? In both cases, the server side use the same API, java.net.ServerSocket?
Is it correct to say that the communication by Socket is faster than URLConnection?
4 Take MSN messenger for example, which protocol does it use? Since proxy configure is only the possible option, so I guess generally the TCP protocol is used directly so that the better perfomrance can be achieved, right?
5 Given 3 computers within the same LAN, can the client, proxy, server environment above be correctly simulated? If so, can
you recommend me some typical proxy program so that I can install it to configure such an enviroment to perform some test?
6 I guess there should be some software to find out which port number a given program/process is going through to connect to
the remote machine, and which port number a given program/process is listening on? Also, what protocl is used in the given
communication.
7 Finally, regarding each of the above questions, it will be highly appreciated that if you can recommed some references,
tutorials, books etc. In summary, what I care about is how to enable the java client behind the proxy and firewall to
communicate with the remote server without problems, so if you know some good tutorials plz let me know and thx in advance!
Finally, thanks for your attention so such long questions =).

FTP is to 25. But it is NOT necessary for the web
server to provide the HTTP listening service at port
80, right? E.g, Tomcat provides the HTTP listening
service at 8080. So it means the default relationship
between the application protocl and their port is
some routine, which is not necessary to follow,
right?Not sure what you're saying here.
There must be a server listening on some port. The client must know what port that is. If you open the connection using the Socket class, you'll explicitly specify the port. If you use some higher level class like URLConnection or something in the commons Net package, there's probably a default port that will be used if you don't explicitly specify another.
There's no way for the client to know that the HTTP request will go to port 80 instead of port 8080. If you think the the client contacts the server without explicitly naming a port, and then asks the server "get me your HTTP server", and the port is determined from that, you're mistaken.
Not sure if you're thinking that, but it sounded like you might be.
2 Assume a LAN connected to the internet through
a proxy, which only allows HTTP protocol, then
questions are:
2.1 Does the proxy recognize the HTTP request
from the client by the port number (carried in the
request string)? For example, when the server
provides the HTTP listening service at 80, then the
request from the client will include the port number
80, then the proxy will parse such info and decide if
or not the request can be out. I'm not sure, but I think most proxies and firewalls are configured by ports. I thought I'd heard of more sophisticated, higher-level ones that could understand the content to some degree, but I don't know anything about those.
3 In java programm, if using the HTTP protcol,
then on the client: the corresponding API is
java.net.URLConnection, right?That's one way.
You might want to look into this:
http://jakarta.apache.org/commons/httpclient/
If using the TCP protocol directly, then on the
client:the corresponding API is java.net.Socket,
right? In both cases, the server side use the same
API, java.net.ServerSocket? A Java client will user Socket, and a Java server will use ServerSocket and Socket.
Is it correct to say that the communication by Socket
is faster than URLConnection?Probably not.

Problem with the new server UCS C220 for set IP to CIMC

Hi
We’ve a problem with the new server UCS C220.
We bought two servers UCS C220 M3 for CallManager 8.6 with High Availability.
When we turn on the server during the boot and when it tells us, oppress F8 to enter at the CIMC and set the IP. But it never enters at the CIMC.
Then, we configure our DHCP server and our switch, we connect the three gigabyte ports to our switch to give him an IP to the CIMC, so and then can enter via browser, but neither works.
Note. The dedicated management NIC does not link, the other two ports do make link.
What do you suggest to put an IP to CIMC and start installing our applications?
regards

You may have noticed that there is no DVD rom on the c220. What you need to do is:
Login into the CIMC from your browser
Luanch the KVM
Insert the VMware DVD in your machines drive
On the KVM pop up there should be a tab to mount the drive, after mounting it click on Macros and choose ctrl_alt+delete to restart.
After the VMware OS installs press F2 to enter IP.
Browse to the VMware ip to download the Vsphere client
Open the Vsphere client, enter the ip of the vmware and the username will be root and no password if you did not set one.
You can now upload OVA templates or manually create virtua machine from this enviroment.
Hope this help

Intermittent proxy error "There is a problem with the proxy server's security certificate. Outlook is unable to connect to the proxy server "

Hi all,
From time to time (at least once a day), the following message pops up on the user's screen:
"There is a problem with the proxy server's security certificate. Outlook is unable to connect to the proxy server . Error Code 80000000)."
If we click "OK" it goes away and everything continues to work although sometimes Outlook disconnects. It is quite annoying...
Any ideas?
Thank you in advance

Hi,
For the security alert issue, I'd like to recommend you check the name in the alert windows, and confirm if the name is in your certificate.
Additionally, to narrow down the cause, when the Outlook client cannot connect again, I recommand you firstly check the connectivity by using Test E-mail AutoConfiguration. For more information, you can refe to the following article:

File transfer, read write through sockets in client server programming java

Hello All, need help again.
I am trying to create a Client server program, where, the Client first sends a file to Server, on accepting the file, the server generates another file(probably xml), send it to the client as a response, the client read the response xml, parse it and display some data. now I am successful sending the file to the server, but could not figure out how the server can create and send a xml file and send it to the client as response, please help. below are my codes for client and server

Client server programming

Hi;
I want to learn client server programming on using windows xp for the client and windows server 2003.
I downloaded the 9.2 windows xp database version for the client . What do I need to download for the server? I see that there is a 32 and 64 bit version for the server.
Thanks for your help!

What I was asking is what should I install on the server
the 32 or 64 bit version of oracle?
I want to learn how to write client/server programs using Oracle.
I have a network at home with one computer serving as the client and another has server 2003 on it.
Again Thanks for your help!

java.net.UnknownHostException: serverpcname: serverpcname
PLZ. GUIDE ME.
THANKS IN ADVANCE.

For a server to be accessible on the inetrnet it needs to have an externally visible IP address. For example, an address which starts with 192.168.1 is for internal use only can only be used by other machines on the same internal network. The server's firewall needs to allow the port you are using access and the client has to be able to lookup up the IP address either using the hosts file or via a DNS service. None of these things have anything to do with Java programming, so if you have any more questions I sugegst you try googling them or ask a forum which relates to these issues.
The connection time out is due to the fact that there is no way to contact an inetrnal address over the inetrnet. The host unknwown means you haven't configured your PC to lookup that address. i.e. the host is unknown.

I encountered a problem with some client machines that use Firefox version 24ESR and IE8.
Ajax requests of aspx pages from Firefox are getting the following error from the iis server (iis version 7.5):
Bad Request - Request Too Long
HTTP Error 400. The size of the request headers is too long.
From analyzing the request that was sent to the server, I saw that the request consist of only the viewstate of the aspx page.
I tried to disable the viewstate for one page and the server got the request correctly.
I do not encounter any issues on these laptops with postback requests from Firefox or when running the same application with IE8.

Sometimes that means that the page address sent is loo long.
Check the link address you are using.
I can't help you further and will send for more help.

Problem with sun app server startup

hi,
i am getting problem with sun app server default start.the error is::
[#|2006-03-01T13:54:35.121+0530|WARNING|sun-appserver-pe8.2|javax.enterprise.tools.launcher|_ThreadID=10;|LAUNCHER005:Spaces in your PATH have been detected. The PATH must be consistently formated (e.g. C:\Program Files\Java\jdk1.5.0\bin; ) or the Appserver may not be able to start and/or stop. Mixed quoted spaces in your PATH can cause problems, so the launcher will remove all double quotes before invoking the process. The most reliable solution would be to remove all spaces from your path before starting the Appservers components. |#]
now i am useing Win Xp operating system,
show me a solution.

Narasimha

You haven;t specified the exceptions you r getting ........while starting your default server.
if u r getting exception about InetClass then connect your system with LAN/Internet then your problem will be solved becoz i m using same location address as you specified, space doesn't matter at all - i think so, it is running fine........
