How to develop chat application in java...
for website (so users who r registerd can chat )

I don't think chat has anything to do with JavaMail.
If you don't even know where to start and you want to support 1 million users,
you're best bet is to hire someone who knows what they're doing.

Thanks in advance.

The VGA is for the 4G iPod only. The 2G can use the composite and component cables.

TNT Website Videos only for Windows?

On http://www.tnt.tv/ when I click on The Company to watch an online program I get a Sad Red Face stating that These Clips can only be watched on a Windows Computer.
I did check their TNT forum and found that other Mac users have the same problem -
Would someone on the forum have any knowledge of this type of problem?
I have Flip4Mac Quicktime flash etc. that all work fairly well on other websites and videos etc.

They exclude any Mac browser so they must have a reason.
They use Windows Media Player format so it must be that the codec used for their files is not available for the Mac OS.
Nothing you can do to change how they do their work. Complain to them in writing or view the files from a very modern PC.

Simple TCP chat application half duplex not working for me

I m having a problem in TCP application working half duplex
My friend runs client program who is in near by city and i run the server program in my system
Let my ip address is 116.x.y.z
My server program is
import java.net.*;
     import java.io.*;
     public class tcpserver
         public static void main(String args[]) throws IOException
          ServerSocket s1=null;
          try
             s1=new ServerSocket(98);
          catch(IOException e)
             System.err.println("Could not find port 98");
             System.exit(1);
          Socket c=null;
          try
             c=s1.accept();
             System.out.println("Connection from"+c);
                                  catch(IOException e)
             System.out.println("Accept failed");
             System.exit(1);
          PrintWriter out=new PrintWriter(c.getOutputStream(),true);
          BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
          System.out.println("I am ready,type now");
          String l=in.readLine();
          while(l!=null)
             out.println(l);
          out.close();
          in.close();
          c.close();
          s1.close();
     }The Client program is which my friend executes is
import java.net.*;
     import java.io.*;
     public class tcpclient
         public static void main(String arg[]) throws IOException
          Socket s=null;
          BufferedReader b=null;
          try
             s=new Socket(InetAddress.getByName("116.x.y.z"),98);
             b=new BufferedReader(new InputStreamReader(s.getInputStream()));
          catch(UnknownHostException u)
             System.err.println("I dont know host");
             System.exit(0);
          String inp;
          while((inp=b.readLine())!=null)
             System.out.println(inp);
             break;
          b.close();
          s.close();
     }Important Note: When i run this program specifying within my system its working ( i mean running the program in two different windows(terminals) its working for me)
When i give the client program to my friend its getting compiling for him but not running for him
Its showing him unknownhost exception and main method not found like this.
Please correct the above code or else just what kind of strategy we should follow in order to get rid of this problem
When i normally run this program in my system
the output when i run in my own system is
Output for running tcpserver.java
~\JDK2~1.0\bin>java tcpserver
Connection fromSocket[addr=/116.x.y.z,port=1930,localport=98] // in output i edit the ip address text
I am ready,type now
this is test text
Output for running tcpclient.java
~\JDK2~1.0\bin>java tcpclient
this is test text
My problem is its working in my system when it exceeds out the output is not available for me
Help me Please !!!

          String l=in.readLine();
          while(l!=null)
          out.println(l);
          }That will print the same thing forever. Make it the same as the loop in the client.
Important Note: When i run this program specifying within my system its working ( i mean running the program in two different windows(terminals) its working for me)Looping forever might be what you call 'working'. I don't.
Its showing him unknownhost exception and main method not found like this.Change this:
new Socket(InetAddress.getByName("116.x.y.z"),98)to this:
new Socket("116.x.y.z",98)although your friend may then run into connectivity problems ...

Proxy-Not able to read from socket for browser IE only for authorized sites

Hi,
I have implemented proxy server using socket connection. For Mozila it works properly, but not for IE.
First it asks for proxy authentication, after providing the username and password for proxy in mozila its asks authentication for the authorized sites and its working properly. But in IE it just ask for proxy authorization and gives error as "you are not authorised to view this page" internally when I went through the code only first time its able to read the request and gives the response, but for the authorized site it wont ask for the username and password. After some time it throws the "Socket connection: reset" exception.
Creates the connection:-
               while(running){
                    try{
                         clientSocket = serverSocket.accept();
                                }catch(SocketException se){
                                        se.printStackTrace();
                               try{
                         new HttpClientConnectionHandler(sockCon);
                    } catch(IOException se) {
                                         se.printStackTrace();
                               }Sends requests and gets the response:-
boolean continueSession = true;
          try{
            SCConnectionManager.increementConnCount();
          while (continueSession){
                    continueSession=false;
                HttpHeader request = rqHandler.getRequest();
                    String con = request.getHeaderValue ("Connection");
               boolean clientPersistentConnection = false;
                    String pcon = request.getHeaderValue ("Proxy-Connection");
                    System.out.println("request = "+request.toString());
                    if( ( request.getHTTPVersion().equalsIgnoreCase("HTTP/1.1")
                                        && !( pcon.equalsIgnoreCase("close") ) )
                              || ( request.getHTTPVersion().equalsIgnoreCase("HTTP/1.0")
                                && ( pcon.equalsIgnoreCase("Keep-Alive") ) ) ){
                              //tempComment     debug("CLIENT Keeping connection true !!!!!! ");
                         clientPersistentConnection = true;
                resHandler.Handle(request);     // Returns boolean ...can check its value...
                         if ( clientPersistentConnection == true && resHandler.connectionPersistent == true ) {
                                   //tempComment
                              debug("SERVER Keeping connection true !!!!!! ");
                              continueSession=true;
                              if ( resHandler.surfAsServer == true ) {
                                   client.setTimeout( persistentConnectionClientReadTimeout );
                         debug("CONTINUING CLIENT CONNECTION "+continueSession);
               System.out.println("out of while loop continue sess = "+continueSession);
          }catch(IOException ioe){
               log(ioe);
               if(qlc.qsm.log.Logger.debugOut) {
                    ioe.printStackTrace();
          } finally {
               synchronized( this ) {
                    int connCount = SCConnectionManager.decreementConnCount();
                SCConnectionManager.updateLastRequestTime();
               close();
     }It does not come out of above while loop.

Sorry, while copy the code one line was missing.
code is:-
while(running){
                    try{
                         clientSocket = serverSocket.accept();
                          } catch (SocketException se) {
                          se.printStackTrace();
                         continue;
                    }catch(IOException se){
                                   continue;
                    try{
                                   SocketConnection sockCon=new SocketConnection(clientSocket);
                                    new HttpClientConnectionHandler(sockCon);
                               } catch(IOException se) {
                         se.printStackTrace();
                                         if ( clientSocket != null ) {
                              try {
                                   clientSocket.close();
                              } catch ( Exception exc ){
                                   clientSocket = null;
                              decrementHttpCount();
                              }

Movie Art not showing for synced movies, only for streamed ones

Movie art is shown correctly in iTunes and while streaming, but not on the movies synced (these show poster frame). The only 'movies' that show correctly their movie art in iTunes, streaming and synced are TV Shows, which has lead me to think that the size of the .m4v has something to do. I have to do tests to determine the posible size limit, but for now all the TV Shows have a file size less than 2GB. I'll try to do some testing as soon as work allows me to get back to a normal life, (T_T)

Back again with some initial findings:
1. Size of the file does not matters. It shows the poster frame for .m4v files of any size.
2. Taking again into account your post, I checked every detail between the ripped TV shows and the ripped DVD movies and everything was the same except one small detail: audio settings. The ripped TV shows had an original Dolby Surround soundtrack, so I encoded them choosing the 'Dolby Surround' audio mix setting in the encoding program while with the ripped DVD movies that had an original Dolby Digital 5.1 I choose the '6 Channel Discrete' AAC 5.1 audio mix.
Noticing this difference, I tried encoding one of the previous movies that had the movie art issue using the same settings, but changing the audio mix setting from '6 Channel Discrete' AAC 5.1 to 'Dolby Pro Logic II'. Imported it to iTunes, applied the Movie cover art, synced with the Apple TV and there was the movie art in the Appke TV.
I'm gonna try again with different movies, but it seems, preliminarily, that the AAC 5.1 encoding setting does something to how the Apple TV sees the movie art in the file tags even though iTunes sees it alright.
I'll let you know what results come out of my tests.
Thanks again.

Can i use java only for database transaction with vb as a front end

Hello All.
I am sorry,i don't know whether this location is the correct location to post my question or not
I have developed one application using complete vb only. That is completly desktop appliation and not suitable for centralized database. Is there any facility to keep my front end as same (vb application) and for the database transaction can i use jdbc? Is there any possibility to do that like View is vb based application and the database connectivity is only jdbc
If my thought is wrongplease execuse me.
thanks in advance

Sounds like a really bad choice even if it was possible.

Doubts over the Performance in Developing a Chat application

We are developing a chat application which needs to update the chat content in the database for the duration of the chat (ie.,For the duration of a session).At the same time the page should refresh and show the current content on both ends.In addition to both these, the database tables has to be checked to detect the occurence of a Network error on both sides.
We have developed it as a Browser based chat and we have used PHP with MySQL. The performance is slow.
Can anyone give a suggestion as to whether we can develop the chat application completely from the scratch and if we do that which technology should we choose to boost the performance.
If anyone is not clear about my problem just mail me.I'll explain it in more detail.
Thanks in Advance

Hi,
I just wanted to know these following answers.
2) Network failure -- Means (either browswer got killed or data did not arrived/Page Not refreshed)
3) which WebSErver are U using?
From java, it is very easy to develop chatting application for which you can use applet and servlets for the same (if you consider the performance is the utmost importance)
Updating to the database should not be done for the duration levels rather should be done at the event levels(data change/keyboards/session -inf changes).
Im not sure about PHPs running at client but I can suggest you to use two frames .One is for typing and other one is for displaying information which basically gets the staus from the server abt other users in the chat either from the session, which would be driven by other component which is static) .
Any how, I just put my ideas (Im sure , you know all these things)
with regards

Using M-Audio Fast Track C400 Audio Interface for FaceTime but only input 1 audio is coming through?...

I'm trying to use my M-Audio interface for FaceTime/U Stream for music purposes. I'm a professional recording artist and I'd like to do some "live stream" concerts for fans from home. I have my keyboard in input 1 and my microphone in input 2. Both signals come through just fine when I'm using Garageband or Logic, but for some reason when I select the interface as the "microphone" option when streaming, only audio from input one is heard from my viewers. I've also switched the keyboard and mic to rule out the mic being the problem, but then the mic audio comes through and not the keyboard...I'm wondering if I'm missing some minute setting somewhere?...I don't understand why it's only for video chat applications that it's only receives one channel of audio...Any help would be appreciated, thanks.

Are you using Logic 8 or 9?
What are you trying to hear Logic's output through?
If you're expecting audio output through built-in audio, and you're using Logic 9, make sure your Fast Track is set as the input device, and built-in audio is set for the output device (both in Logic's audio preferences)
However, if you're using Logic 8 or 7, you need to create an aggregate device if you're using built-in output.
Details here:
http://discussions.apple.com/thread.jspa?messageID=8813763&#8813763
OR
use the FastTrack's audio outputs to drive your monitoring, NOT your built-in audio.

I want to give sales discounts only for the first five sales order

The scenario is that I have to limit the sales discount to first five sales order that is executed, from the 6th the system should not allow any sales discounts

Hi,
If I understand your requirement correclty you want to pass discount for a particular item for a customer only for the first five sales orders irrespective of the quantity you sell on this order. As I understand this way of limiting discount by way of the count of sales orders is not possible.
What is though possible is to limit the discount per customer or per article or per customer and article combination to either a certain fixed value of discount or limit the discount to certain fixed quantity sold for that article.
The config required is
Condition type : Scale basis -Either value scale or quantity scale. Scale type -leave this blank.
Condition record :Chose the scale type as "B- To Scale" and at the time of condition record creation you can define your own Calculation type -either fixed amount,percentage,quantity etc.
All the best.
