Creating public class that makes simultaneous requests in JSP
hi!
this is continuous question of the following question.
https://www.experts-exchange.com/questions/21338416/JSP-timing-program-and-all-hit-the-URL-at-the-same-time.html
I was trying to create public class in scriplets, but I had compile errors. And calling Test () method twice did not help. Also Test() needed to return something and by making while loop infinite didn't compile either and that is how I changed like this.
Now how do I call this Test() method simultaneously?
