Java Server Socket & C++ Client Socket

[rajeshks99]

Hi,
We have a socket server app in Java and the client application in C++.

When we try to connect 60 clients simultaneously from C++ using threads, only 55-56 connections are successfull, rest are not connected(Connection refused error).

For one connection everything works fine. In server side each connection is handled in seperate thread.

Is there anything else to be done?

The server code is as follows.
public class SocketServer
{
public static void main(String args[])
{

ServerSocket Server = null;
Socket clientSocket = null;

try
{
Server = new ServerSocket(7999,60);
}
catch (IOException e)
{
System.out.println(e);
}

try
{
while (true)
{
clientSocket = Server.accept();
SocketThread objThread = new SocketThread(clientSocket);
objThread.start();
}
}
catch (Exception e)
{
System.out.println(e);
}
finally
{

try
{
Server.close();
}
catch (IOException e)
{
System.out.println(e);
}
}

}
}

The number of sockets that can be opened is limited by the operating system where your server runs.
