Answer 1

If I'm understanding you correctly this is how your data flow would look like?

HTML Form Data --> Java Servlet --> HTML Data ?

The approach I would, is by using Java Beans to populate your data. They are just normal java class with private fields, getters and setters to store value. Refer here for more information

Form

<form action"YourServlet">
<!-- Your input e.g username and submit button -->
</form>

SERVLET

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

BEAN

//private field correspond to your form data value e.g userName
//constructor no arg
//getters and 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>
