RE: ArrayList vs. Vector - which is better for webapps?

What the hell was I thinking?! I must've been tired this morning when I wrote the last post. I meant to say Serializable not Synchronized!! Yikes - what a blunder! Does this change your feelings? What if I have a UserForm (extends ActionForm) that has an ArrayList of children? I usually put a user's Form in the session, so I can access their information at any time.

According to the Struts API documentation (both 1.0.2 and 1.1) "An ActionForm is a JavaBean... Such a bean will have had its properties initialized from the corresponding request parameters". My rather superficial understanding of this statement is that there is one ActionForm instance per request which obviates any synchronization concerns for that instance's state (the "ArrayList of children"). Some peculiar application logic can, of course, make this conclusion false but the control of such logic is the application developer's responsibility. Have a good day :)
