How appears a new JSP file in the same page?

Question

Hello all,
I have a JSP file in a portal page.From this file I want to open another one.The new file must be opened in the same portal page with the same size and exactly in the same place. But it always openes a completely new page and the portal page disappears.I know that the mistake is from the provider file, but I don't know what should I change.
Thanks for your help!

In my.jsp you could put a form with n submit buttons whith different values of parameter "name", like this:
---My.jsp------
<form method="yourMethod" action="My.jsp">
<input type="submit" value="Button1" name="button1">
<input type="submit" value="Button1" name="button2">
<input type="submit" value="Buttonn" name="buttonn">
</form>
<%if(request.getParameter("button1")!=null){%>
<jsp:include page="f1.jsp">
<%}%>
<%if(request.getParameter("button2")!=null){%>
<jsp:include page="f2.jsp">
<%}%>
<%if(request.getParameter("buttonn")!=null){%>
<jsp:include page="fn.jsp">
<%}%>
I didn't try it but it might work.
