Is there any reason to do server side logic in JSP instead of calling methods from external classes?

Question

I have a web app running in jetty and in the JSP I e.g insert some values to my DB the following way:

 <% 
if(request.getParameter("id") != null && request.getParameter("value") != null){
int poiId = Integer.parseInt(request.getParameter("id"));

int value = Integer.parseInt(request.getParameter("value")); 

FirstExample.insertReading(value, id);   // here I 
}
%>

Is there a reason why I should not do method calling like this? I could have performed this useing JTSL i think its called?

You can use Servlet, in MVC model JSP is mainly used as view. No need to deal with big logic in JSP.

Exactly. Each JSP translates to Servlet implementation by the server, anyway :) – Vadim Nov 11 '16 at 15:32

There is no reason to do it at all. Actually, put the logic/actions in JSP is a bad practice. Separate logic out of JSP is much better design. Same logic can be used by many JSPs or other implementations.
