I think it purely depends on your requirement. But why do you want an InputStream as a class variable. I think that is very costly resource and you are blocking a resource.Others i think you can use it based on your requirement. For iteratorsif u declare it as class level variables if the underlying collection changes the iterator gets in valid. -----Original message----- From: Carl Smith [EMAIL PROTECTED] Date: Tue, 10 Jan 2006 19:35:58 -0800 To: Struts Users Mailing List user@struts.apache.org Subject: which is a good instance variable
