I have a html file

An easy and quick way is to let your jsp generate the apropriate javascript which will reload your nav frame

something like this:

     <!-- your accepted jsp frame content here -->
     <script language="javascript">
           top.navigationWindow.location.href = 'userAcceptedNav.html'
<% } else { %>
   We are sorry, but you are a illegal user!
<% } %>

make sure you name your nav frame the same as the navigationWindow used in the script
