How can get a data(/information) from server using servlet and pass it to swing.simillarly from swing to servlet. i.e in MVC architecture can i use swing or applet instead of JSP to act as View mode
HTTP to a servlet can be done through the HttpUrlConnection class, or Jakartas HttpClient package, if you need some extra functionality. You can serialize objects over such connection. A web services approach would work as well.
I guess technically this might still be considered an MVC approach, although it's probably closer to correct to call the server components the business/data access layer.
