Passing parameter to jsp:include with c:set

[anfun wong]

How can I pass a parameter using only standard tags (not snipplets) to a dynamically included jsp? Here is what I have tried:

In parent jsp:

<c:set var="productId" value="<%= productBean.getId() %>" scope="request" />
<jsp:include page="//content/prod.jsp" flush="true" />

In child jsp, when I try to access productId, I got a servlet exception.

Although the following works:

<% request.setAttribute("productId", productBean.getId()); %>

and able to access productId in child JSP.

Do you not think it might be helpful to include the details of said exception?

This is for JSP 1.2. Container is WSAD 5.1.2.

Actually just got a little further - no exception now. But the value is not being passed in. It's empty. The code is still the same though, just a server restart.

Thanks!

I assume that you are using JSTL 1.0 as you are using JSP 1.2? (Unless you have a really good reason not to, an upgrade to JSP 2.0/JSTL 1.1 will make you a much happier person).

If so, are you using the _rt JSTL URI's?

Hi Bear,

If so, are you using the _rt JSTL URI's?

Thanks for the tip. _rt works.

Actually I probably would have tried turning the runtime expression <%= productBean.getId() %> into a proper EL expression - ie

<jsp:useBean id="productBean" class="com.mypackage.ProductBean" scope="page"/> 
<c:set var="productId" value="${productBean.id}" scope="request" />

Thanks Stefan,

Yes you are right. I did have to use Java because I'm only patching this JSP and the existing variable productBean is not available to the tags.

Is there a good document illustrating the various name spaces involved in JSP and JSTL and how they correlate and interact, and how to communicate variables among them? I have only found pieces of info here and there.

Thanks!
