}
}
Create a jsp page where the generator tag <s:generator> generates an iterator with “id”
attribute and <s:iterator> tag prints it out
using the <s:property /> tag. The separator
attribute separates the val into entries of the
iterator.
The scriplet as shown below generates an
iterator and put it in the PageContext under
the key as specified by the id attribute.
<%
Iterator i = (Iterator)
pageContext.getAttribute(“myAtt”);
while(i.hasNext()) {
String s = (String) i.next(); %>
<%=s%> <br/>
<% }
