Help with JSTL usage

[Davie Lin]

Hi everyone, thanks for reading my question. I appreciate any opinion offered by anyone.

I am working on a company website and trying to include a chunk of HTML code in a JSP if a user is new to our site. First, I use scriplets like the following

<% if(session.isNew()) {%>
<jsp:include page="greeting.html"></jsp:include>
<% } else {%>
<cut value="Welcome back"></cut>
<% };%>

the above scriplet work perfect for my purpose. However, I don't want to use scriplet so I mod the code above using JSTL tags

<c:choose>
<c:when test="session.isNew()">
<jsp:include page="greeting.html"></jsp:include>
</c:when>
<ctherwise>
<cut value="Welcome back"></cut>
</ctherwise>
</c:choose>

the <c:when> tag is not getting evaluated when I delete the cookie and reopen this JSP. Can anyone suggest where I can change to make it work like the scriplets?

Thank you

The test attribute in your c:when tag is has a String literal in it.

You'll want to replace that with an EL expression.
test="${pageContext.session.new}"

<c:when test="session.isNew()">

The test attribute to <c:when> must contain a valid EL expression. You've just given it a text string.

You might try the following:

<c:when test="${pageContext.session.new}">      

and then bone up on EL expressions in order to understand the difference.

Ah, Ben and I bonk heads so often!

Also, please be sure to use UBB code tags when posting code to the forums. Unformatted code is extermely hard to read and many people that might be able to help you will just move along. Please read this for more information.
