Subject: Re: Open Source Object Caching Systems compatible with Struts From: "Vic C." <[EMAIL PROTECTED]> === Are you caching objects than? You can append to a linked list from here: http://gee.cs.oswego.edu/dl/classes/collections and than have a thread slowly write to db. That would be a que.
If you need db caching, poolman on sourceforge does db caching (and object caching). Use that for caching. What is the load you expect? What is the hot spot you expect? hth, V.
