You cannot use custom tags inside a scriptlet, so the above solution won't
work.

How about something like this (although Struts isn't really designed to
make scriptlets work well, it does cooperate with them :-):
<%
Vector names = new Vector();
names.addElement("John Doe");
names.addElement("Jane Doe");
pageContext.setAttribute("names", names, PageContext.PAGE_SCOPE);
%>
<logic:iterate id="name" name="names" type="java.lang.String">
The current name is <%= name %>.
</logic:iterate>
The "type" attribute on the <logic:iterate> tag determines the Java type
of the scripting variable that is created (name). By default, it is
java.lang.Object.
