Subject Re: Quick question about iterators & beans on a page
Date Fri, 15 Feb 2002 15:19:58 GMT
In the action that will be forwarded to your jsp you put a list(e.g. an 
ArrayList)  on the request.  This list contains bean of some kind.
Then in your jsp you can write : 

<logic:iterate id="item" name="NameOfMyListOnTheRequest" scope="request">
   <bean:write name="item" 
property="SomePropertyOfTheBeansThatAreInTheListOnTheRequest" />
