Re: Need help on logic:iterate
This is only a debugging type suggestion, but you could put your interate inside of a logic:present name=user property=schedule SCHEDULE WAS FOUND your iterate /logic:present tag and make sure that the collection is being found.

Hi, Yes user is your bean. Have you send it in a session context with session.setAttribute(user,variable) in your Action Class ?

Re: Need help with logic:iterate :)
You're closing your first element, so the iterate never gets to the bean:write until after the loop is finished. You have: logic:iterate id="storerooms" name="storeroomList" scope="application" property="storeroomList"/ It should be (note the lack of the trailing slash): logic:iterate id="storerooms" name="storeroomList" scope="application" property="storeroomList" If you only want to do something for one specific bean, then use logic:equal inside the iterate tag. -- Dan Miser http://www.distribucon.com From: "Alex Colic" [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: "Struts" [EMAIL PROTECTED] Subject: Need help with logic:iterate :) Date: Thu, 19 Apr 2001 15:50:44 -0400 I have attempted the below but the only storeroom name to be printed out to the screen is the last storeroom.

RE: Need help with logic:iterate :)
Your logic:iterate tag closes itself before it gets to the tag body. i.e. logic:iterate/ I made this mistake a couple times too so don't feel bad! On your bonus question, your JSP shouldn't be performing business logic, the bean should be. Create another getter on your bean for the specific thing you want to display. Alternatively, inside your logic:iterate you could wrap a logic:equal tag around your bean:write and conditionally display a particular value within the iteration.
