please post me sample code of jsp , java program asap

if i'm understanding correctly how data flow like?

html form data --> java servlet --> html data ?

the approach would, using java beans populate data. normal java class private fields, getters , setters store value. refer here more information

form

<form action"yourservlet"> <!-- input e.g username , submit button --> </form>

servlet

//request data //do calculation //populate bean //dispatch jsp

bean

//private field correspond form data value e.g username //constructor no arg //getters , setters //other methods

jsp

<body> <jsp:usebean id="bean" class="package.beanclass" scope="session"/> value: <jsp:getproperty name="bean's id" property="property name"/> </body>
