  • 0

I am using a servlet which passes a String parameter to another Servlet in another remote system, to get xml response from that remote servlet.

This works fine when i tried to connect to that remote Servlet from my local PC.

But I am getting the error java.net.SocketException: Unexpected end of file from server when I execute same from another server.

Error:

Code in My Servlet (client):

if(queryString.equals("Inventory")) {

   String partNum = (String)session.getAttribute("PARTNUM");
   String locId = (String)session.getAttribute("locids");

   strURL = strURL+"/InventoryStatus?queryStr=Inventory&PARTNUM="+partNum;

   URLConnection dbGatewayURL = new URL(strURL).openConnection();

   BufferedReader in = new BufferedReader(new InputStreamReader(dbGatewayURL.getInputStream()));//--This is line 52 Mentioned in Error above

   StringBuffer responseData = new StringBuffer();
   String line="";

   while((line = in.readLine()) != null) {
      responseData.append(line);
   }

   String result =responseData.toString();
   request.setAttribute("inventryStock",result);

   RequestDispatcher rd=request.getRequestDispatcher ("inventryStatus.jsp?resp=Yes");
   rd.forward(request, response);  
}

    There was nothing wrong with the code but the thing was the remote server wasn’t listening to the connection from my server, hence i tried the same code but on another remote server this time and its working fine….! any body know the reason…………?
