Why doesn't it return anything?

Question

Java

this code:
public ModelAndView demo(@PathVariable String paginationNum,HttpServletRequest request) {
...

on the local server it returns the path I need, but on the server it doesn't return the path!

Can someone explain to me why??)

Answer 1

Maybe your app is deployed on the server in the root context? That is, available (for example) at server.com? And on localhost:8080/myapp.
In this case:
>> For servlets in the default (root) context, this method returns "".
What do you generally want to do?
