Hello Friends

[Pratik Surti]

My project is for online trading, in which registerd customer can discuss trading, pricing on chat.

When i will click on online trading button(By selecting the particular person who is online and with whom i want to do chat) it should open a chat window.

I am using servlet, jsp, RMI and swing (Swing as chat window). How should i call that chat window from browser ? which way will be more appropriate ? please guide me.

regards
pratik

How should i call that chat window from browser ?

I am assuming that the chat window is a separate Java application, not an applet managed by the browser.
In that case the simplest thing would be to have the server relay messages between the browser and chat window. How does the chat window "talk" to the client on the other end of the chat?

Browser displays the link to open the chat window to chat with that particular person. I want to know that How I can call the chat window means the Swing from my JSP page.

You would have to implement your swing app as either an applet or a Java Web Start application.

We have forums for both of those technologies here.

when you click on online trading button in the jsp page uou just activate the servlet which again invokes your swing (application)
for this there are many ways to open other applications from a java program

by using this ocde you can solve it

import java.io.*;
public class RunTime {
public static void main(String arghsp[])throws Exception
{
Process p = Runtime.getRuntime().exec("java Test1");
p.waitFor();
 
System.out.println(p.exitValue() == 0 ? "no error" : "error");
 

 

 
}
 

}

And...
Once this code fires up a swing app on the server, how is the user (sitting at the client machine) supposed to use it?

yes you are right...
it opens at server side

actually the code i have provided in the above thread is not correct

and even this code which i am providing here for normal programs (console)
it is working fine
but in webapplications it is not working
can anyone tell me why it is not running i have also place one swing application called Calculator in the current directory(where the servlet is placed)

 
      try{
System.out.println("Starting Lunch...");
Runtime r = Runtime.getRuntime();
Processp = r.exec("java Calculator");//if i ran this in normal java program it is ok but whn i run this as part of servlet it is not working
 
InputStream is_input = p.getInputStream();
int x;
while((x=is_input.read()) != -1) System.out.print((char)x);
 
p.waitFor();
System.out.println(p.exitValue());
}
catch(Exception e){}

should i need to give the absolute path???

thanks in advance
