You need to use JSP. Forward request from servlet to jsp setting daat in attribute.

in Servlet

request.setAttribute("attrName","Value");

now forward this request to jsp, and on jsp access this attrName with

${attrName}

See

You can use JSP or AJAX,JavaScript to send the request to the servlet and receive the response to update the third textbox...
