if u putting the orderedsandwiches in the session scope in action class ,
then no Need of having <bean:define> tag in the JSP .
Also instead of keeping that in the session scope in the action class. U can
very well populate the form bean with the contents of that array &
use following in JSP page . Here listOfSandwithces is the array attribute of
the actionForm bean which
<logic:iterate id="element" name="orderedsandwiches"
property="listOfSandwitches" >
<bean:write name="element" property="element" >
<logic:iterate>
