A HashMap would work fine unless you care to add/remove people or permissions without restarting your app server. If changing the security information is important to you, then you'll either need some method to expire old data or make sure that whatever you do to change the security information also changes the cache.
I'm currently caching my group information using an object that extends HashMap but also does time-based and size-based expiration. So I have a 5 minute cache. -----Original Message----- From: Christian, Joanne To: Orion-Interest Sent: 3/6/2002 12:00 PM Subject: Caching Group Information Hi All, I am using a custom user manager that gets group and user information from the database. I would like to cache the database information when the user manager is initialized; and access the cache to get the user information. Can anyone suggest the best method for doing this? I am thinking about using a hashmap, but I'm not quite sure what is the best option. Thanks, Joanne
