Connection refuse

[Venkatesh Sangam]

Hi,

I am generating 5 requests per second on the tomcat server using the following program.

How will I know if the connection is refused by tomcat. If the server is overloaded 
with requests it starts refusing them. I have to capture this using my program below. 
can anybody please tell me how do I do it.

I am also not sure if the Threads that are refused connection are getting any response 
back ..
Please help
Thanks,
Venkatesh.


public class TestTomcat extends Thread{
 
 private static int request=0;

 public void run() {
  try{
  String inputLine;
  URL url = new URL("http://localhost:8080/examples/servlet/TestTomcat?request="; + 
++request);
  URLConnection connection = url.openConnection();
  connection.setDoOutput(true);
  BufferedReader inp = new BufferedReader(
    new InputStreamReader(
    connection.getInputStream()));
  while ((inputLine = inp.readLine()) != null)
      System.out.println(inputLine);
     
   inp.close();
  }
  catch(Exception e){}
  }
 

    public static void main(String[] args) {

  int m=0;
 try{
  for (int p=0;p<100;p++){
   for(m=0;m<5;m++){
    TestTomcat rg= new TestTomcat();
    rg.start();
   }
   Thread.sleep(1000);
  }
 }
 catch(Exception e){}

 }

}
