and want display value of 1 of variable.

first of if class not accessible in jsp need import class

<%@ page import="com.my.yourclass" %>

second need call method of class want output or said want use value of variable make sure should initialized can directly use jsp expression.

<%= new yourclass().variablename; %>

you can use directly display variable value html page make sure variable should accessible means should not private.

you can use scriplet that
