Steps to follow:

Just convert the file js.html to js.jsp.
Get the post parameter from the request parameter.
Set the value in hidden div in JSP and access it in JAVA.

Change the action attribute of form tag as shown below:

<form action="http://localhost:8080/popnnn/js.jsp" method="post">

Try any one:

JSP Scriplets

<div id="fooParameter" style="visibility: hidden;">
     <%=request.getParameter("foo") %>
</div>

JSP Standard Tag Library

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<div id="fooParameter" style="visibility: hidden;">
    <c:out value="${param.foo}" />
</div>

Access value from hosted HTML/JSP to JAVA code

String foo = RootPanel.get("fooParameter").getElement().getInnerHTML();

TextBox text=new TextBox();
text.setText(foo);
