Problem with MultiThreading

[afmustac <af...@yahoo.com>]

Hello everyone,

I am using HttpClient version 3.0.1 in my project. I am creating several threads and each thread is responsible for uploading data to some websites. I have defined my HttpClient object as:

MultiThreadedHttpConnectionManager connectionManager = new MultiThreadedHttpConnectionManager();                 
client = new HttpClient(connectionManager);

and I am passing the "client" object to my threads as:

Thread[] awa = new Thread[_iNumThreads];        
            
for (int i = 0; i < awa.length; i++) {                                                    
                    
      Connotea oConnotea = new Connotea("connotea_"+i,_iNumThreads, _oUpdateMan,_lConsistencyInterval,ctc,_sData, client);                    
      awa[i] = new Thread(oConnotea);        
 }       
//start threads here
  for(int y=0;y<awa.length;y++){
      awa[y].start();    
 }

I have run my above code with 1 thread and 10 thread total separately..I thought that I will not get this exception with one thread but I am still getting it.I might be using something wrong and I really appreciate your time and any help...And the exception as:

java.net.SocketException: Connection reset

I tried to follow HttpClient Threading guideline but I might use something wrong in my implementation..I really appreciate any help. Thank you so much for your time and response..

That is not a multithreading problem, it is a problem with
the server you are connecting to. Make sure you have the
proxy configuration set up correctly. Try to access the
server with a browser, then take that browser's proxy settings
and establish them in your application.
