Answer 1

..put VitalTrackApplet_MOD.jar under WebContent/WEB-INF/lib folder.

http://localhost:8080/WEB-INF/lib/VitalTrackApplet_MOD.jar

If you change localhost:8080 & try that URL in the browser address bar you might note the server refuses to supply the Jar that is in a directory explicitly intended for the server side of a web-app. (IE not the client JRE).

The fix is to move the Jar (and codebase) to a place where any client can access it.

Answer 2

when you run your index.jsp it find VitalTrackApplet_MOD.jar under same folder. Please put your VitalTrackApplet_MOD.jar under WebContent folder.
