Hi,
This is really easy with jsp. I'm doing something similar. I don't have the code here,
but
it goes something like:
in servlet.java:
HttpRequest req; // this is passed to you
HttpSession sess = req.getSession();
sess.setAttribute( "errorMessage", "Something terrible has happened." );
And I have this code in a file called header.jsp, which is included by other pages.
It uses the Standard Tag Library:
<jsp:useBean id="errorMessage" scope="session" class="java.jang.String"/>
<c:if test="${errorMessage.length == 0}">
<c:out value="${errorMessage}"/>
</c:if>
Good luck,
Michael
