Http post getting socket write error

Hi, I am doing HTTP post using Pub.client:http service and getting the error as follows. I cross checked the URL and it is correct. ServerError: (com.wm.app.b2b.server.ServiceException: java.net.SocketException: Software caused connection abort: socket write error) Could you please advise your ideas about the error? Thanks, Capri_lak.
