java.net.SocketException: Connection reset While using Apache HTTPClient

I am using HTTPClient for file upload.
The first time it is giving an exception like this

But when I do it again (In JFrame by pressing submit button again) its working fine.

What is the problem?

My code looks like

client.getHostConfiguration().setProxy(proxyHost,port);
if(userName!=null)
{
      HttpState httpState = new HttpState();
      httpState.setProxyCredentials(new AuthScope(proxySettings.proxyHost,port),new NTCredentials(proxySettings.userName,proxySettings.password,proxySettings.proxyHost,proxySettings.proxyDomain));
      filePost.setDoAuthentication(true);
      client.setState(httpState);
}
else
{
      filePost.setDoAuthentication(false);
}
client.getHttpConnectionManager().getParams().setConnectionTimeout(1000*60*60);
int status = client.executeMethod(filePost);

line no. 459(indicated in error trace)  is last line --->>int status = client.executeMethod(filePost);

the server is closing the connection for some reason, check the server logs.

It means that the server for some reason closes the connection while the client is still reading from the socket. If you've got access to the server logs, take a look in there to see if you find an indication about what is happening.

I am using Apache Tomcat 6.0 app server.
There I have checked for these files
stdout.log
localhost.log
Catalina.log
stderr.log
 and unable to find any traces of it.

Its a servlet for receiving file upload & the code looks like

ServletFileUpload            upload            =      new ServletFileUpload();
FileItemIterator            iter            =      upload.getItemIterator(request);
FileItemStream            fi            =      iter.next();
fileName                              =      fi.getName();
Streams.copy(fi.openStream(), new BufferedOutputStream(new FileOutputStream(new File("c:\\upload\\temp\\", fileName)),1024*1024*10), true, new byte[(1 << 20)*10]);

and there sre some lines for database connection to MySQL.

Well in that case it should not work for the second time also.

The servlet may see a new request. You need to make the alteration in case you need to avoid a null pointer exception too
