Answer 1

before accessing variable inside html you need to initialize the variable and then do whatever the calculations and other modifications inside another JSP code block. Now you can access the variable inside the html. This is my first answer for the Stackoverflow.com please experts notify the mistakes i've done.

<% java.lang.Integer var=0; %>
<%
  int a;
  int b;
  var=a+b;
%>
<% out.print(var);%>
