Re: iterate collection
I think you need to say name=roles instead of collection=roles. Assuming there is as roles.getValue() accessor, the rest looks fine. If not, you may just need bean:write:element if the objects in roles have a toString() method. Simon Liang wrote: Hi: Can someone help with this?

RE: iterate collection
you need to add the collection to the request object java.util.Collection roles = client.getUserRoles(admin); request.setAttribute(roles); then logic:iterate id=element name=roles this will work --- Simon Liang [EMAIL PROTECTED] wrote: hi: I tried the suggestion, but still didn't work.
