Using jsp: param / c: param in a portlet environment

I am trying to enable JSP pages with jsp:paramin a portlet environment (using the Pluto portlet container ).

eg,

<jsp:include page="test.jsp">
   <jsp:param name="foo" value="bar"/>
</jsp:include>

and in test.jsp,

<c:out value="${foo}"/> or <%= request.getParameter("foo") %>

The output is always zero, and I also tried using tags c, but got the same result.

<c:import url="test.jsp">
   <c:param name="foo" value="bar"/>
</c:import>

I was browsing the network and many people faced the same problem, except that there was no solution for it.

Is this a limitation or is there another way to do this?
