thank you for your response, Paul... this is actually inside a struts
tile.. entire code for the tile is (directives omitted):

===========================
<%
String theSponsor = "";
%>
<table><tr><td><img src="..."></td></tr><tr><td>

    <%
    theSponsor = request.getParameter("sponsor");
    if (theSponsor.equals("") || theSponsor == null) {
        response.sendRedirect("/ws/sponsors/index.jsp");
        %>
        <script language="JavaScript" type="text/javascript">
        alert("param has no value");
        </script>
<%-- <jsp:forward page="/ws/sponsors/index.jsp" > --%>
        <%
        return;
    } else if (!theSponsor.equals("") || theSponsor != null) {
    %>

<%-- CUSTOM TAG (to include param in question..) HERE... --%>

<% } %>

</td></tr></table>

===========================

thank you very much..

Do you have any content being sent to the user before this code gets

I have a response.sendRedirect() in a JSP, to be triggered if a param
passed in request evaluates to "" or null.. however, sendRedirect is
being ignored; also tried <jsp:forward..>, is also ignored.. would
appreciate some help.. thank you.. code is as follows:

<%
theSponsor = request.getParameter("sponsor");
if (theSponsor.equals("") || theSponsor == null) {
    %>
          // following test alert triggers fine, the rest is ignored..
    <script language="JavaScript" type="text/javascript">
    alert("test");
    </script>

    <%
    // following ignored...
    response.sendRedirect("/ws/sponsors/index.jsp");
    %>

    <%-- // following also ignored..
    <jsp:forward page="/ws/sponsors/index.jsp" > --%>
    <%

    return;
} else if (!theSponsor.equals("") || theSponsor != null) {
%>

    <%-- code for a custom tag here, using "theSponsor" var as one of
the parameters inside the tag... --%>
<% } %>

thank you very much...
