you should use c:forEach to achieve such dynamic building functionality.

Call me a purest but I would rather use a a rich or a4j component iteration component like Repeat or DataList and not c:forEach. Sometimes c:forEach causes conflicts and the output data gets mixed up. Especially with nested loops.

Sorry for the typos in my last message.

It's not possible with repeat. And the reason is - c:foreach actually creates the components in the component tree on building view. And the repeat based components just iterate the same components from the tree at rendering phase.
