You code (slightly modified) worked fine for me, so my guess is that
something's NQR with how you're filling the List or placing it in the
request. That or the code you posted isn't actually the code that's
producing the error.

Here's some code you can include at the bottom of your JSP...
http://wiki.wendysmoak.com/cgi-bin/wiki.pl?DebugJSP
It just prints out everything in the request/session/context... make sure
everything is where you think it is.

For starters, try just <bean:write name="foos" /> and make sure it can find
the list, and that the list has what you think it has in it. Hopefully your
'Foo' class has a good 'toString' method.

(You don't have to <jsp:usebean> with the Struts tags, it knows how to look
in the various scopes to find objects. Anyway, it's not complaining about
'foos', it's complaining about 'nextElement' inside the iteration.)
