I think I'm using the proper syntax on a <jsp:forward>.  But its giving me an error.

How do I fix this?
<% if(myVariable.equals("X")){ %>
          <jsp:forward page="<c:out value="${form.forward}" />            " />
<%} %>

ERROR

I think you cannot put a JSTL tag inside jsp:forward tag. You can do the following:

<jsp:forward page="<%= ((MyForm)request.getAttribute("form")).getForward() %>"/>

Does  <jsp:forward page="${form.forward}"/>   work for you?

try

<c:if test="${param.myVariable == "X" }">
<c:redirect url="<c:out value="${form.forward}" />" />
</c:if>

Jaggernat,

your solution puts a line that says "url has moved here".  where here is a link to the page I need?

Any way to make it automatically go to that page?

hmm, intresting.

what is the value of     "<c:out value="${form.forward}" />"


redirect normally will forward to the url value.


you can try this too


<c:if test="${param.myVariable == "X" }">
<jsp:forward page="<c:out value="${form.forward}" /> " />
</c:if>

if 'form' is a bean instance, just call it like:

<% if(myVariable.equals("X")){ %>
     <jsp:forward page="<%=form.getForward()%>" />
<%} %>

<c:redirect url="${form.forward}" />  should be good enough.   No need to put c:out inside it

Thanks. I test it in my WSAD.
Actaully, both <jsp:forward page="<%=form.getForward()%>" />  and  <c:redirect url="${form.forward}" />  work OK.
