I have written a PersistenceManager class that handles all database access and uses the SQLData interface to map java objects to User Defined Types in the oracle database. Every request now has to create a new instance of the persistencemanager so there is no sharing whatsoever. I would like the persistencemanager to look in the object cache first and if the object is not there retrieve it from the database. I need a way to keep this cache in memory so all requests can use the same cache.

i hope this makes things clear..

Shared between requests?
Shared between user sessions?
Shared between applications (contexts)?
Shared between machines?

Can you give us a better description of what you are trying to do?

Hi there,

I would like to implement my own shared object cache in
my webapp. Does anybody have some ideas on how to
do this?
