Question

Can I write methods in JSPs? (Java Server Pages)

I tried writing a method within the body of the JSP, but my IDE doesn't seem to like it.

JSP can only show information to user, if you want to do some elaboration you have to re-call a servlet that to that for you.

Analize and try using this: Everything in your jsp.

But i recommend you that if your a gonna use methods, use classes instead. They are safer and loads quite faster when calling them.

<%
   //Your main logic
   out.print(myMethod());
%>
<html>
     your client side content
</html>
<%!
   public String myMethod(){
      return "Method called successfully";
   }
%>
