Using c:forEach with Seam, JSF, and Facelets

After a couple of hours of scratching my head and Googling the Interwebs like a mad man I finally figured out why my c:forEach wasn’t iterating and displaying the data in my view. Come to find out I was using the wrong name space when declaring the JSTL core library.

First off here is the c:forEach code.

1
2
3
4
<c:forEach items="#{item.tags}" var="tag">
  <h:outputText value="#{tag.name}"/>
  <br/>
</c:forEach>

Here is the incorrect name space causing the issues. Notice the word jsp in the path.

1
xmlns:c="http://java.sun.com/jsp/jstl/core"

Now for the correct name space. Just remove the word jsp from the path.

1
xmlns:c="http://java.sun.com/jstl/core"

Bingo. Now everything is working. Don’t make same boneheaded mistake.

    Dennis,

    You are very welcome. Glad to know it helped somebody. This issue threw me for a loop because the other namespace is valid but just doesn’t work.
