I am having trouble getting nested tags to work in Tomcat. The code
below results in the error that follows. If I remove the nested forEach
it works. If I use Item <c:out value="${item}"/><br> in the first
forEach it fails. The second .jsp code shows how it does work in
Tomcat4. We've had the same experience with custom tags we wrote.
I would greatly appreciate any help I could get with this. TIA.

pageContext.setAttribute("vector", v);
