/**
*
* @param request
* @param response
* @throws ServletException
* @throws IOException
*/
@Override
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {


Dude, in the long run your code won't work if you don't put this you need to send "post" method to the servlet..
Replace above code to First.java and as well as Second.java

Then it will work..

.Thanks for your video :) cheers
