What do you want to do with that variable?
When you use tag libraries and beans and stuff like that, you're
supposed to kind of live in that environment exclusively. There's no
guarantee that the lcoal variable "p" will exist, so you can't just do this:
<%
p.toString();
%>
All the "variables" defined through things like <c:forEach> are likely
to be stored in the "page" context which isn't represented directly by
local variables (or, at least, isn't guaranteed to be).
Perhaps there's a tag for what you want to do with this variable.
Perhaps you'll have to develop one.
If this is all JSTL, then you may be able to just do:
${p}.toString()
..or something like that.
