I assume that the MenumedBean.jsp creates a menu like:
<LI><A HREF=/jsp/WomanJSP/Function1.jsp>Function1</A>
<LI><A HREF=/jsp/WomanJSP/Function2.jsp>Function2</A>
<LI><A HREF=/jsp/WomanJSP/Function2.jsp>Function3</A>
Since you say you can't use Cookies you must instead use URL rewriting
for session tracking. This means that when you create your A HREF tags
you must encode the URLs with the HttpResponse.encodeURL method, so
that the servlet can add the session ID to the URL. The result should
look like:
<LI><A HREF=/jsp/WomanJSP/Function1.jsp;$sessionid$1234>Function1</A>
<LI><A HREF=/jsp/WomanJSP/Function2.jsp;$sessionid$1234>Function2</A>
<LI><A HREF=/jsp/WomanJSP/Function2.jsp;$sessionid$1234>Function3</A>
